This study focuses on the role of AI in shaping Generation Z's consumer behaviors across fashion, technology, beauty, and education sectors. Analyzing responses from 224 participants, our findings reveal that AI exposure, attitude toward AI, and AI accuracy perception significantly enhance brand trust, which in turn positively impacts purchasing decisions. Notably, flow experience acts as a mediator between brand trust and purchasing decisions. These insights underscore the critical role of AI in developing brand trust and influencing purchasing choices among Generation Z, offering valuable implications for marketers in an increasingly digital landscape.


Introduction
In today's digital era, Artificial Intelligence (AI) is revolutionizing consumer-brand relationships, particularly among Generation Z. Born into a world of technology, this generation engages with AI in ways that profoundly transform their consumption behaviors and expectations.The integration of AI into marketing practices is a burgeoning phenomenon, critical for understanding and adapting to the evolving dynamics of consumer behavior.This research is timely and relevant as it delves into how AI is shaping these new dynamics, especially among younger, tech-savvy consumers.
The advent of Artificial Intelligence (AI) is particularly evident in its transformative shift in consumer behavior, most notably among Generation Z. Born between 1997 and2005, this demographic segment emerges as a pivotal market force, distinguished by their innate digital fluency and substantial future spending power.Their unique expectations and sophistication in technology usage, especially regarding AI, make them a critical group for study in marketing and emerging technology contexts.This paper studies into the complex interplay between AI and Generation Z's consumer behavior.It scrutinizes how AI exposure, attitude toward AI and AI accuracy perception, along with the mediating effect of flow experience, shape brand trust.This trust, in turn, is examined for its impact on purchasing decisions.The exploration of these relationships aims to shed light on the multifaceted dynamics of AI's influence on consumer behavior, particularly in the context of brand trust and its downstream effects.Understanding Generation Z is vital for brands aiming to adapt and thrive in the digital era, as their consumption patterns and attitudes toward AI are indicative of broader market trends.AI exposure, defined as the frequency of an individual's interaction with AI in their daily life, is a significant factor in shaping consumer behavior (Abrardi et al., 2022).Globally, AI-powered devices and services have become a ubiquitous part of consumers' lives.It is projected that the majority of customer interactions are expected to be managed without human intervention, signifying the pervasive influence of AI in our daily routines and interactions (Stephanidis, 2019).
Attitudes toward AI, which span a spectrum from fear and skepticism to enthusiasm and acceptance, have been identified as a significant determinant of consumer behavior (Mantello et al., 2023).A substantial body of research suggests that consumers globally are increasingly comfortable with AI, particularly when it enhances the convenience of their interactions with businesses (McLean et al., 2021;Meyer-Waarden and Cloarec, 2021;Pitardi and Marriott, 2021).This trend underscores the importance of understanding and addressing consumer attitudes toward AI, as these attitudes can significantly influence the acceptance and use of AI-powered services.
The perception of AI's accuracy, gauged by an individual's belief in the precision of AI's recommendations or decisions, is another critical factor influencing brand trust (Figueroa-Armijos et al., 2023).Research indicates that consumers are more likely to trust AI advice when they perceive the AI to be reliable (Ameen et al., 2021;Chi et al., 2021;Shin, 2021).This finding highlights the importance of ensuring the accuracy of AI systems, as consumer trust in these systems can significantly impact their willingness to follow AI recommendations and, ultimately, their purchasing decisions.
Flow experience, characterized by a state of complete immersion and involvement during an activity, has emerged as a relevant concept in understanding consumer interactions with AI (Nguyen et al., 2022).Research suggests that when consumers experience a state of flow while using AI-powered services, they are more likely to perceive the service as enjoyable, engaging, and valuable (Baabdullah et al., 2022;Kautish and Khare, 2022).This positive flow experience can lead to increased satisfaction, trust, and loyalty toward AI systems.
Brand trust, a key variable in this study, is considered a significant mediator in the relationship between AI and consumer behavior (Ameen et al., 2021;Hasan et al., 2021).It is measured based on the level of confidence an individual has in a brand's AI systems and the extent to which they rely on AI-based recommendations or decisions from the brand (Chi et al., 2021).Research underscores that trust in AI systems is a critical factor influencing consumers' purchasing decisions, highlighting the importance of building and maintaining brand trust in the era of AI.
The dependent variable in this study, purchasing decision, is assessed based on various factors.These include whether the individual makes a purchase (Allal-Chérif et al., 2021) and their satisfaction (Cheng and Jiang, 2020;Prentice et al., 2020) with the purchases made based on AI's recommendations.These variables are critical indicators of the effectiveness of AI systems in influencing consumer behavior and enhancing the shopping experience.
The primary objective of this research is to unravel the complex dynamics between AI and consumer behavior within Generation Z.We aim to investigate the direct effects of AI exposure, attitudes toward AI, and perceptions of AI accuracy on brand trust, as well as the consequent impact on purchasing decisions.Additionally, this study seeks to explore the role of flow experience as a mediating factor in these relationships.By achieving these objectives, the research intends to offer valuable insights into the evolving landscape of AI in marketing and provide strategic guidance for effectively engaging with the digitally adept Generation Z market.

Literature review
In the context of the theoretical framework, this section aims to provide a concise overview of the interplay between AI and Generation Z's consumer behavior.The focus of this study is to explore the relationships among key variables: AI exposure, attitude toward AI and AI accuracy perception, flow experience, brand trust and purchasing decisions.Understanding these relationships is crucial for comprehending the impact of AI on brand trust and its subsequent effects on consumer behavior.By studying into these variables, marketers can gain valuable insights to navigate the AI landscape effectively and enhance the overall consumer experience.Generation Z's unique positioning as the first true digital natives makes their analysis imperative in studies concerning AI's impact on consumer behavior.Their integral role in shaping future market trends, coupled with their distinct consumer attitudes formed in the digital age, provides unparalleled insights into the evolving landscape of consumer-brand interactions in the AI era.This demographic's engagement with technology goes beyond mere usage; it shapes their expectations, trust, and loyalty toward brands, making their study crucial for understanding and forecasting market dynamics in the age of AI.
. AI exposure and brand trust Artificial Intelligence (AI) exposure refers to the frequency and extent of an individual's interaction with AI in their daily life.This exposure can occur through various channels, such as AI-powered devices, services, and applications (Abrardi et al., 2022).The ubiquity of AI in modern life has made AI exposure a significant factor in shaping consumer behavior (Rodgers et al., 2021).As AI becomes increasingly integrated into our daily routines and interactions, it is transforming the way consumers interact with brands and make purchasing decisions (McLean et al., 2021).
AI exposure is particularly relevant in the context of online business and e-commerce.For instance, in fashion and apparel industry, affiliate marketing systems, which are often AI-powered, have become a popular marketing tool (Yeo et al., 2022).These systems can increase the exposure of products and services, thereby enhancing brand visibility and credibility.
The relationship between AI exposure and brand trust has been a subject of interest in recent research (Hasan et al., 2021;Youn and Jin, 2021;Minton et al., 2022).Brand trust is a critical factor influencing consumers' purchasing decisions.In this research It will measure based on the level of confidence an individual has in a brand's AI systems and the extent to which they rely on AI-based recommendations or decisions from the brand.
The influence of AI exposure on brand trust has been substantiated by a wealth of research across various industries.In the hospitality sector, for instance, studies have found that the trust in AI-powered affiliate marketing systems can significantly impact consumers' intentions to book accommodations.This trust is often intertwined with factors such as social contact and consumers' selfefficacy in navigating the AI interface (Bhushan, 2021;Khaliq et al., 2022;Rasheed et al., 2023).
Similarly, in the realm of e-commerce, research has underscored the role of trust in online vendors and merchants in mitigating the perceived risks of online transactions (Kim et al., 2021).This trust is often shaped by consumers' perception of the benefits of AI, such as enhanced security and the reputation of the website, as well as their familiarity with the AI system (Micu et al., 2021;Fedorko et al., 2022;Fonseka et al., 2022).
In the gaming industry, where AI is increasingly used to enhance user experience, studies have shown that players' trust in the game's AI system can significantly influence their engagement with the game.This trust is often linked to the perceived fairness and competence of the AI system (Yang and Nazir, 2022;Khatri, 2023;Xia, 2023).
These findings collectively suggest that increased AI exposure can bolster brand trust, thereby influencing consumers' purchasing decisions.However, it is crucial to note that the impact of AI exposure on brand trust is multifaceted and may be contingent on other factors.These include the perceived accuracy and reliability of the AI system, the individual's attitudes toward AI, and their past experiences with AI.
In the context of Generation Z, AI exposure takes on a unique dimension, given their innate digital fluency and constant interaction with emerging technologies.This demographic, accustomed to the omnipresent AI in their daily lives, provides fertile ground to explore how this exposure affects their trust in brands.While previous studies have examined the relationship between AI exposure and brand trust, there is a significant gap in the literature regarding how this dynamic specifically unfolds within Generation Z.
Our study addresses this gap by exploring whether increased AI exposure among Generation Z consumers leads to greater brand trust.This approach not only contributes to understanding Generation Z's interaction with AI but also provides valuable insights for brand management strategies in the digital age.Therefore, we propose the following hypothesis: Hypothesis 1: Increased AI exposure positively influences brand trust among Generation Z consumers.

. Attitude toward AI and brand trust
Research has shown that attitudes toward AI can significantly influence brand trust (Qin et al., 2020;Ahn et al., 2022;Yang and Wibowo, 2022).For instance, in the realm of e-commerce, studies have underscored the role of trust in online vendors and merchants in mitigating the perceived risks of online transactions.This trust is often shaped by consumers' perception of the benefits of AI, such as enhanced security and the reputation of the website, as well as their familiarity with the AI system (Khrais, 2020;Nagy and Hajd, 2021;Rashidin et al., 2021).
In the context of viral marketing, the appeal and credibility of the message source, which often communicates the use of AI, have been found to significantly impact consumers' attitudes toward the brand.This suggests that the way AI is utilized and communicated in marketing messages can influence consumers' attitudes toward AI and, consequently, their trust in the brand (Hayes et al., 2021;Vlačić et al., 2021;Ameen et al., 2022).
In the airline industry, studies have shown that customers' attitudes toward traditional and social media marketing, where the use of AI is often communicated, can affect brand trust and purchase intention.This indicates that the medium through which AI is presented and its use is communicated can influence consumers' attitudes toward AI and their trust in the brand (Rana et al., 2021;Singh, 2021).
These findings collectively suggest that attitudes toward AI can significantly influence brand trust.However, it is crucial to note that the impact of attitudes toward AI on brand trust is multifaceted and may be contingent on other factors.These include the perceived accuracy and reliability of the AI system, the individual's past experiences with AI, and their exposure to AI.As such, a comprehensive understanding of these dynamics is essential for leveraging AI effectively to build brand trust and enhance consumer satisfaction.
In the domain of Generation Z, attitudes toward AI play a pivotal role in shaping brand trust.This demographic, known for its adaptability to technology, may demonstrate unique perspectives on AI, influencing their trust in brands utilizing AI technologies.
Studies in e-commerce and viral marketing have highlighted how consumers' perceptions of AI, including its benefits and application, shape their trust in online vendors and brand messages (McLean et al., 2021;Marjerison et al., 2022).Additionally, in industries like airlines, the way AI is communicated through marketing channels has a significant impact on brand trust and purchase intentions (Tussyadiah and Miller, 2019).
These findings suggest that Generation Z's attitudes toward AI, influenced by the factors such as AI's perceived accuracy and past experiences, are crucial in building brand trust.This study extends this understanding by examining how positive attitudes toward AI among Generation Z consumers can enhance brand trust.Therefore, we propose the following hypothesis: Hypothesis 2: Positive attitudes toward AI positively influence brand trust among Generation Z consumers.

. AI accuracy perception and brand trust
Artificial Intelligence (AI) accuracy perception refers to an individual's belief in the precision of AI's recommendations or decisions (Nadarzynski et al., 2019).This perception is a critical factor in shaping consumer behavior and influencing brand trust (Pelau et al., 2021).As AI systems become increasingly sophisticated and accurate, they are transforming the way consumers interact with brands and make purchasing decisions (Wang et al., 2022).
AI accuracy perception is particularly relevant in the context of online business and e-commerce.For instance, in the airline industry, studies have shown that customers' attitudes toward AI, as presented through traditional and social media marketing, can affect brand trust and purchase intention.This indicates that the medium through which AI is presented and communicated to consumers can influence their perceptions of AI's accuracy and their trust in the brand (Mayer et al., 2020;Kim et al., 2021;Strich et al., 2021).
The influence of AI accuracy perception on brand trust has been substantiated by a wealth of research across various industries.In the realm of recommender systems, studies have found that consumers are more likely to trust AI advice when they perceive the AI to be reliable (Abbass, 2019;Shi et al., 2021).This trust is often intertwined with factors such as the perceived benefits of AI, such as enhanced security and the reputation of the website, as well as their familiarity with the AI system (Cabiddu et al., 2022).
In the context of social media influencers, research has shown that consumers' attitudes toward AI influencers can significantly impact brand trust and purchase intention (Alboqami, 2023).AI accuracy perception, gauged by an individual's belief in the precision of AI's recommendations or decisions, is pivotal in shaping brand trust (Kim et al., 2021).In marketing communications, the manner in which AI is incorporated can sway consumers' perceptions of its accuracy (Cheng and Jiang, 2022).If AI is used to provide personalized, accurate product recommendations, it could enhance consumers' perception of the brand's AI accuracy, thereby boosting their trust in the brand.This trust can subsequently influence purchasing decisions (Kumar et al., 2019).
These findings collectively suggest that positive perceptions of AI's accuracy can bolster brand trust, thereby influencing consumers' purchasing decisions.However, it is crucial to note that the impact of AI accuracy perception on brand trust is multifaceted and may be contingent on other factors.These include the individual's attitudes toward AI, their past experiences with AI, and their exposure to AI.As such, a comprehensive understanding of these dynamics is essential for leveraging AI effectively to build brand trust and enhance consumer satisfaction.
In the digital landscape where Generation Z is a significant player, the perception of AI's accuracy is crucial in shaping brand trust.This demographic, known for its critical engagement with technology, values the precision of AI systems in their interactions with brands (Guo and Luo, 2023).Research across various sectors, including e-commerce and retail, highlights that when AI is perceived as accurate and reliable, it significantly enhances consumers' trust in brands (Ho and Chow, 2023;Nazir et al., 2023).
For Generation Z, the way AI is presented and its perceived reliability in providing personalized and accurate recommendations are key factors influencing their trust in a brand.This study extends these findings by examining the impact of AI accuracy perception on brand trust among Generation Z consumers, offering insights into how their unique perceptions of AI shape brand relationships.Therefore, we propose the following hypothesis: Hypothesis 3: Positive AI accuracy perception positively influences brand trust among Generation Z consumers.

. Brand trust and purchasing decisions
Brand trust encapsulates the faith and confidence consumers harbor regarding the sincerity and integrity embodied in a brand's actions and communications (Portal et al., 2019).This trust extends to an anticipation that the brand will act favorably, even in scenarios where consumers lack control or face uncertainty regarding the outcomes (Gretry et al., 2017).
The pivotal role of brand trust lies in its capacity to foster and sustain long-term relationships with consumers (Menidjel et al., 2017).Trust in a brand ameliorates perceived risk associated with purchasing decisions (Kim and Chao, 2019;Arruda Filho et al., 2020), thereby cultivating a more loyal consumer base.This loyalty often translates to repeat purchases and favorable recommendations (Quaye et al., 2022).Moreover, consumers exhibit a willingness to pay a premium for products from trusted brands, attributing additional value to the safety and quality these brands epitomize (Chakraborty, 2019).
The nexus between brand trust and purchasing decisions has garnered substantial attention in marketing academia, particularly within the e-commerce milieu.Empirical evidence posits that brand trust exerts a direct influence on consumers' purchase intentions (Zuech et al., 2015;Zhao et al., 2019;Nosi et al., 2021).For instance, a notable study delineated the mediating role of brand trust in the relationship between perceived website quality and purchase intention (Qalati et al., 2021).
Similarly, investigations within the retail sector have unveiled a significant impact of brand trust on consumer loyalty, which subsequently shapes repeat purchase behaviors (Diallo et al., 2021).This impact is particularly pronounced in high-risk product categories, where consumers' reliance on a brand's reliability and consistency is paramount (Dabholkar and Sheng, 2012).
Moreover, the extant literature posits that brand trust can serve as a bulwark against adverse information.In instances of negative publicity or unfavorable product reviews, consumers with established trust in the brand are more inclined to adopt a lenient stance or interpret the adversities less harshly (Folse et al., 2013;Bhandari and Rodgers, 2020).
In the context of Generation Z, brand trust becomes increasingly significant.Known for their discerning nature and reliance on digital information, Gen Z's trust in a brand heavily influences their purchasing decisions (Serravalle et al., 2022;Pradhan et al., 2023).This demographic, more than previous generations, values authenticity and integrity in brand communications, which in turn shapes their buying behavior.Trust alleviates perceived risks, fostering loyalty and a propensity for repeat purchases among Gen Z consumers (Ismail et al., 2021;Joshi and Garg, 2021).
Empirical studies within the digital marketplace have shown a direct correlation between brand trust and purchase intentions for Gen Z, particularly in online environments where trust is paramount (Tabassum et al., 2020;Kim-Vick and Yu, 2023).Our study aims to further investigate this relationship, proposing the following hypothesis: Hypothesis 4: High brand trust positively influences purchasing decisions of Generation Z consumers.
. Flow experience as a mediating variable in brand trust and the purchasing decisions Flow experience, a concept introduced by Csikszentmihalyi and Csikszentmihalyi (2014), refers to a state of complete immersion and involvement during an activity, characterized by a loss of selfconsciousness and a sense of optimal experience.In the context of AI interactions, flow experience can be understood as the degree to which an individual is fully engaged and absorbed in the interaction with the AI system (Baabdullah et al., 2022).This experience is often associated with a sense of enjoyment, engagement, and satisfaction (Kautish and Khare, 2022).
The importance of flow experience in AI interactions lies in its potential to enhance the user's perception of the AI system and their overall experience (Ashfaq et al., 2020).When users experience a state of flow during their interaction with an AI system, they are more likely to perceive the system as enjoyable, engaging, and valuable (Nguyen et al., 2022).This positive flow experience can lead to increased satisfaction, trust, and loyalty toward the AI system, thereby influencing their future interactions and decisions related to the AI system (Sampat et al., 2023).
The relationship between flow experience and brand trust has been explored in various retail and e-commerce contexts.Research has indicated that consumers' flow experience can significantly impact their trust in brands (Shim et al., 2015;Guerra-Tamez and Franco-García, 2022).This trust is often shaped by consumers' perception of the brand's benefits, such as its reputation, quality of products or services, and their familiarity with the brand (Iglesias et al., 2019).
Empirical research has shown that when consumers perceive a brand as useful and relevant, they are more likely to experience a state of flow.This flow experience, in turn, has a substantial positive impact on their brand loyalty.For example, in Bilgihan (2016) it states that consumers' flow experience significantly influenced their trust in a brand, which subsequently affected their loyalty to the brand (Bilgihan et al., 2014).Other research by Ozkara et al. (2017) indicated that consumers' flow experience during their interaction with a brand positively influenced their trust in it, which then influenced their purchase intention.These studies underscore that fostering a positive flow experience for consumers can critically enhance brand trust and loyalty.Likewise, it has also been proven that the positive flow experience has been indicated as a mediating variable in this relationship, which suggests that a positive flow experience can increase trust in the brand and, consequently, affect repurchase intentions (Bilgihan, 2016).
Flow experience, defined as a state of complete immersion in an activity, holds particular significance in the context of Generation Z's interactions with AI systems.This research explores how flow experience may mediate the relationship between brand trust and purchasing decisions among this demographic.With Generation Z's inherent familiarity with digital technology, their flow experience in AI interactions could uniquely influence their brand trust and purchasing behaviors.While flow experience has been studied in various contexts, its specific application to Generation Z's AI interactions is a less explored area.Therefore, we propose: Frontiers in Artificial Intelligence frontiersin.org Hypothesis 5: Positive flow experiences mediate the relationship between brand trust and purchasing decisions among Generation Z consumers.The relationships formulated in this study are shown in Figure 1.

Methodology . Data collection
The choice to focus on the Generation Z demographic in this study is rooted in their unique characteristics as digital natives and their emerging influence in the consumer market.This generation's deep integration with digital technology, particularly AI, offers a distinct perspective on brand trust and purchasing behaviors.Their interactions with AI in online shopping provide a rich context for examining the nuances of AI's impact on consumer behavior (Ameen et al., 2023).The insights gained from this focus are instrumental in understanding the evolving landscape of AI in marketing and consumer engagement.
To initiate the data collection process, preliminary outreach was made to several prominent universities in Mexico.Formal invitation letters were dispatched to the academic and alumni relations departments of these institutions, seeking their collaboration and consent for data collection.Out of the institutions approached, Universidad de Monterrey, Universidad Autónoma de Nuevo León and Tecnológico de Monterrey granted permission to proceed with the research.
To ensure the specificity of our study's focus on Generation Z, stringent selection criteria were employed.The target respondents were defined as individuals belonging to Generation Z, specifically those aged between 18 and 26 during the data collection period (July-September 2023), aligning with the birth years 1997 to 2005.This age criterion was a key determinant in the participant selection process, and initial filtering questions were included at the beginning of the survey to confirm the respondent's age group.A post-survey data verification process was also implemented to further validate that participants fell within the Generation Z age bracket, maintaining the integrity of our targeted demographic study.
The survey instrument was initially drafted in English and then translated into Spanish to cater to the primary language of the target audience.To ensure the accuracy and relevance of the survey items, a back translation method was employed.
To mitigate the potential for common method bias in our study, we carefully designed our survey to include procedural remedies.This involved randomizing the order of the questions to reduce patterned responses.Additionally, we used varied question formats to prevent response biases that can arise from monotonous answering patterns.These measures were implemented to ensure that our data accurately reflects the independent contributions of each variable, enhancing the validity of our findings.
Further refinement of the questionnaire was achieved through in-depth interviews with both academic representatives and a select group of Generation Z students and alumni.A pilot study, involving 40 participants, was also executed to ascertain face validity and the clarity of the questionnaire's wording.Given the digital nature of the platforms and the techsavviness of the Generation Z demographic, an online survey was chosen as the mode of data collection.The survey was distributed via university email systems and alumni networks, with the cooperation of the participating institutions.After a span of 3 months (July-September) dedicated to data collection, a total of 224 filled-out questionnaires were retrieved, marking them ready for data analysis.This sample size was deemed adequate, considering the multiple variables in the proposed model and the recommendations from previous literature on sample sizes for comprehensive data analysis.Table 1 shows the technical information of the study.

. Measurement
In our study, we operationalized several constructs, as delineated in Table 2.These constructs encompass AI exposure, attitude toward AI, AI accuracy perception, brand trust, flow experience, and purchasing decision.Each of these was gauged using a seven-point Likert scale, anchored at 1 (strongly disagree) and culminating at 7 (strongly agree).
All constructs were tested using 4 items.The dimension of AI exposure was probed drawing inspiration from a framework proposed by a specific author.The construct of attitude toward AI was shaped leveraging measures conceived by another distinguished author.The metrics to discern AI accuracy perception were tailored based on the groundwork laid by yet another author.We turned to established literature, referencing a specific author, to delineate the measures for brand trust.The items gauging flow experience found their genesis in the works of a particular author.Concluding our set of constructs, the purchasing decision was assessed using metrics aligned with the insights of a certain author.
Our survey instrument was initially crafted in English.To ensure cultural relevance and accuracy, it was subsequently ./frai. .translated into Spanish by a native Mexican academic.A second native Mexican scholar, well-versed in English and immersed in an English-speaking milieu, further reviewed, and refined the translated version.To bolster the robustness of our data collection we employed strategies such as randomizing the sequence of certain items and introducing variations in the phrasing within the primary survey instrument.Data analysis and results

. Sample profile
A comprehensive survey was conducted, gathering responses from a diverse group of 224 participants.The gender distribution revealed that the majority, 67.1%, were females, followed by 27.3% males and a smaller segment of 5.6% identifying as other.Age-wise, the largest group, 56.6%, fell into the 18-20 age bracket, with those under 18 years accounting for 13.3%.The majority had completed high school, comprising 70.6% of the sample, while 28% had obtained a college degree, and a mere 1.4% held a master's degree.When examining occupation, a striking 88.8% were students, with minimal representation from full-time and part-time workers at 2.8% and 7% respectively.On the topic of online activity, 36.4% spent 3-4 h daily, closely followed by 35.7% investing 5-6 h.Most participants displayed a medium level of tech-savviness (63.6%), with 34.3% considering themselves highly familiar with technology.
In terms of online purchasing behavior, 43.4% had been shopping online for over 3 years.The primary online purchases were in fashion, accounting for 63.6% of the sample, followed by tech and mobile apps at 17.5% and beauty products at 11.9% (Full results are shown in Table 3).

. Measurement model
The suggested framework was corroborated using a CFA on the entire dataset through the PLS Algorithm in Smart PLS4.0 and SPSS Statistics 29.The key findings from this analysis, alongside the descriptive metrics for the constructs examined in the framework, are highlighted in Table 4.The standardized coefficients (β) exceeded 0.715, marking an optimal situation.On employing both Smart PLS 4.0 and SPSS Statistics 29, the Cronbach alpha values ranged between 0.713 and 0.827.These figures are deemed satisfactory as per existing literature.The constructs' composite dependability surpassed 0.822, and the average variance extracted (AVE) for each construct exceeded 0.537.Hence, the robustness of the constructs in our study's framework for the entire dataset stands affirmed.Moreover, the model's fit is in line with expectations, registering above 0.90 for the NFI metric at 0.931 and below 0.08 for the SRMR at 0.071.

. Structural equation modeling
Following CFA, the structural model was tested.The hypothesized relationships in the research model have been contrasted using bootstrapping analysis via the Smart PLS 4.0 software.The results for the sample are presented in Table 5 and Figure 2, and according to the SEM analysis, all the relationships proposed in the research model have been contrasted successfully.
. /frai. .To evaluate the intermediary role of the flow experience, we assessed its indirect influence.This is calculated as the disparity between the total effect and the direct effect, as articulated by Christian Nitzl (Nitzl et al., 2016).As depicted in Table 6, the outcomes were significant.Given the significant outcomes in the direct effect of the brand trust and purchasing decision, the flow experience is confirmed as a partial mediating variable, thereby supporting hypotheses H6.

. Validation of the measuring instrument
The discriminant validity was assessed based on the criteria set by Fornell and Larcker.In the diagonal, the AVE values were placed to evaluate them against other factors in the correlation coefficient.Findings revealed values exceeding 0.5, validating the discriminant nature of all the factors (see Table 7).
The collinearity statistics, as denoted by the VIF, were examined, indicating an absence of complications in the partial least squares estimations (Table 8).
. Goodness-of-fit diagnosis Tenenhaus et al. (2004) have proposed a methodology for determining the global goodness of fit (GoF).The GoF metric evaluates the congruence between a model and an observed dataset.This calculation juxtaposes observed values with those projected   by the model.The method encapsulates the integrity of both the measurement and structural models (Tenenhaus et al., 2005).
The derived global goodness of fit (GoF) value was 0.49, surpassing the benchmark GoF of >0.36 as proposed by Wetzels et al. (2009).Consequently, it can be inferred from this investigation that the research model exhibits a satisfactory overall fit.

Discussion
In this research, we examined the influence of Artificial Intelligence (AI) interaction factors-specifically, AI exposure, attitude toward AI, and AI accuracy perception-on brand trust among Generation Z consumers across five sectors: fashion, technology and mobile apps, beauty, and books and education products.The study's methodology deployed a bootstrapping analysis to meticulously dissect the various relationships among these factors.These findings resonate with previous studies in the field, as depicted in Table 9.

Brand trust → Flow experience → Purchasing decision Bilgihan et al., 2014;Shim et al., 2015;Bilgihan, 2016;Ozkara et al., 2017;Iglesias et al., 2019;Guerra-Tamez and Franco-García, 2022 Once the independent variable of brand trust was explained, its positive relationship with the dependent variable purchasing decisions that explained the university student's perception of learning was verified.Likewise, the relationship between brand trust and the flow experience was verified.These results coincide with other works in the literature, as shown in Table 10.
Finally, this study also verified the mediating effect of the flow experience variable between the relationships of purchasing decision.These results coincide with other works in the literature shown in Table 11.
Furthermore, our findings on AI's influence in the marketing sector are reflective of the broader role of AI as a disruptive technology across various industries.As detailed in the systematic literature review on AI as a disruptive technology (Pȃvȃloaia and Necula, 2023), AI's transformative impact extends beyond marketing into sectors like healthcare, education, and urban development.This broader perspective of AI's role underscores its potential to reshape consumer interactions and expectations, particularly among digitally native populations like Generation Z.The insights gained from this study, therefore, not only contribute to understanding AI's influence in marketing but also echo AI's expansive and transformative capacity in various sectors.
. Findings and contributions, ethical considerations, limitations, and future research suggestions This study embarked on an exploration into the role of AI interaction factors through AI exposure, attitude toward AI, and AI accuracy perception in brand trust.Further, it delved into understanding the subsequent ripple effect this trust has on the purchasing decisions of Generation Z consumers across five distinct sectors: fashion, technology and mobile apps, beauty, and books and education products.Rooted in the belief that positive AI interactions amplify brand trust, thus swaying purchasing decisions favorably, this research uniquely positions itself at the confluence of AI and Generation Z's purchasing behavior.Through this lens, the study uncovers the transformative potential of AI on market dynamics and its broader implications for crafting marketing strategies tailored to this tech-savvy generation.

. Findings and contributions
The research unearthed pivotal insights, establishing that AI exposure, attitude toward AI, and AI accuracy perception play a significant role in fostering brand trust.Furthermore, brand trust was found to a robust predictor of purchasing decisions.A notable discovery was the partial mediating effect of the 'flow experience' between brand trust and purchasing decisions, adding a nuanced layer of understanding to the AI-consumer interaction dynamics.
The findings of this study are particularly illuminating when considering the unique characteristics of Generation Z.As digital natives, their interactions with AI are more intuitive and frequent compared to older generations.This inherent comfort with technology makes their responses to AI exposure, attitudes toward AI, and perceptions of AI accuracy especially relevant for marketers.Our study reveals that Generation Z's trust in brands is significantly influenced by these AI interaction factors, suggesting that marketers targeting this demographic should prioritize AI integration and transparency to build and maintain brand trust.
Moreover, the distinct purchasing behavior of Generation Z, influenced by AI, underscores the need for brands to adapt their strategies to this generation's preferences.This study's insights into the mediating role of flow experience between brand trust and purchasing decisions are particularly valuable.They suggest that creating engaging and immersive AI experiences can be a key strategy in appealing to Generation Z consumers.
These findings also open new avenues for future research.While this study focused on Generation Z, it would be insightful to compare these findings with other generational cohorts to understand generational differences in AI interaction and its impact on consumer behavior.Additionally, the unique characteristics of Generation Z identified in this study provide a valuable framework for developing targeted marketing strategies that resonate with this technologically adept generation.
In light of our study's findings, it is imperative to acknowledge the potential for alternative explanations in interpreting the influence of AI interaction factors on brand trust and purchasing decisions among Generation Z. Factors such as cultural nuances (Priporas et al., 2017), socio-economic status (Puiu et al., 2021) and individual differences in technology acceptance and digital literacy (Verma et al., 2021) may also play a moderating role in this relationship.Additionally, external market dynamics, including competitive pressures (Varsha et al., 2021) and market saturation (Guo and Luo, 2023) within the sectors analyzed, could have significant implications on consumer behavior.These considerations suggest that the interplay between AI and consumer behavior is subject to a complex matrix of variables, both internal and external to the individual.
. Ethical implications of AI in marketing to generation Z Alongside our findings on AI's influence on Generation Z's purchasing behavior, it's crucial to consider the ethical implications of AI in marketing.Key ethical aspects such as autonomy, the right to explanation, and value alignment, as discussed in Bertoncini and Serafim (2023), are paramount in AI systems.Generation Z, as digital natives, have heightened expectations for transparency and ethical conduct in AI interactions.Marketers should prioritize these ethical considerations to maintain trust and align with the values of this generation.The development and implementation of AI in marketing strategies should be guided by ethical principles that respect consumer autonomy, provide clear explanations of AI decisions, and align with societal values, ensuring responsible engagement with Generation Z consumers.

. Limitations
This research, while offering crucial insights into the AIrelated purchasing behaviors of Generation Z, inherently bears the limitation of focusing solely on this demographic group.While the study succeeds in providing a thorough understanding of Generation Z's unique relationship with AI, this singular focus potentially limits the generalizability of the findings across different generational cohorts.Generations like Millennials, Generation X, and Baby Boomers have their own distinct experiences and levels of technological engagement, which might lead to varying perceptions and interactions with AI.Therefore, the results of this study, though profound in the context of Generation Z, need cautious extrapolation when considering broader generational implications.
Furthermore, the adoption of a cross-sectional design was purposeful.This approach efficiently captures the current state of AI interactions, offering a clear snapshot of the present landscape.While it provides a robust overview of the current scenario, it also lays the foundation for future longitudinal studies to track evolving trends and causal dynamics over extended periods.
By acknowledging these considerations, we aim to provide clarity on the study's scope and to pave the way for complementary research endeavors that can build upon this foundation.
. Future research suggestions Building on the findings and limitations of the present study, several avenues for future research emerge: Diverse demographics: While this study centered on Generation Z students, future research could diversify the sample to include working professionals, entrepreneurs, and other segments within Generation Z to gain a holistic understanding.
Generational comparative studies: In light of the study's focus on Generation Z, future research should aim to include a broader range of generational cohorts.Comparative studies involving multiple generations would provide valuable insights into generational differences and similarities in AI interactions, brand trust, and purchasing behaviors.Such studies could help in understanding the broader implications of AI across the consumer spectrum and aid in developing more comprehensive marketing strategies.
Longitudinal design: Adopting a longitudinal approach would provide insights into the evolving nature of AI interactions and its impact on brand trust and purchasing decisions over time.
Broader geographical scope: Expanding the research to different regions or countries could offer cross-cultural insights into how different Generation Z cohorts perceive and interact with AI in the context of brand trust.
In conclusion, as AI continues to weave itself into the fabric of consumer interactions, understanding its multifaceted impact on brand trust and purchasing decisions, especially for the digital natives of Generation Z, remains paramount.This study serves as a foundational step in that direction, paving the way for more nuanced and expansive explorations in the future.
