Background

In an era shaped by flexible work schedules, AI-assisted decision environments, and rising cognitive fatigue, understanding how biological rhythms influence decision-making has become critically relevant.

Decision-making is a multifaceted process subject to a wide array of influences, with psychology, neuroscience, and social sciences each contributing critical perspectives. Yet, while contemporary studies have addressed social, psychological, and environmental factors, the role of internal biological timing, specifically chronotypes, remains underexamined.
Chronotypes, or individual differences in preferred activity times, influence peaks in alertness, arousal, and emotion regulation, with downstream effects on cognitive and attentional performance. As a result, early-type (morning) and late-type (evening) individuals may exhibit substantial differences in decision accuracy, speed, and risk tolerance depending on time of day, fatigue, and how well their environment aligns with their biological rhythm.

Gaps remain in both mechanistic understanding and translational application, particularly regarding how circadian alignment (or misalignment) impacts judgment accuracy, risk tolerance, and fatigue in high-demand settings. Everyday decisions, including consumer and lifestyle choices, may serve as accessible, real-world models for understanding circadian influences on motivation, impulsivity, and perceived risk.

This Research Topic aims to bridge chronobiology and decision neuroscience, reframing current models by integrating the influence of circadian biology and chronotypes into the cognitive and neural processes behind decision performance. We seek to clarify how inter-individual differences in biological timing modulate neural, cognitive, and behavioral facets of decision performance across diverse domains, from laboratory settings and animal models to real-world professional, clinical, consumer and political environments.

Key questions to be addressed include:

i. How do early and late chronotypes differ in their susceptibility to fatigue and risk during decision-making?

ii. What neural circuits underpin time-of-day effects on impulse control and cognitive flexibility?

iii. How might tools and organizational practices be adapted to account for chronotype diversity for better outcomes?

This Research Topic calls for interdisciplinary research to understand how biological rhythms and chronotypes, modulate decision performance, with emphasis on real-world translational relevance. The aim is to better inform individual, clinical, consumer, and organizational outcomes in high-stakes and high-fatigue environments.

Studies will explore tasks tapping into impulsivity (e.g., delay discounting, Go/No-Go), risk tolerance (e.g., Iowa Gambling Task), temporal discounting, and intolerance to delay or uncertainty. Studies using neurobiological techniques (e.g., EEG, fMRI, eye-tracking), hormonal and biomarker indicators (e.g., DLMO), and chronobiological assessments in real-world contexts are particularly encouraged.

We welcome articles addressing, but not limited to:

• Neurobiological mechanisms linking chronotype and decision-making
• Effects of chronotype and time-of-day on impulsivity, risk-taking, and temporal discounting using behavioral tasks (e.g., Iowa Gambling Task, BART, Go/No-Go)
• Circadian misalignment, decision fatigue, and performance decline in professional contexts
• Methodological innovations in assessing chronotype and circadian phase in field settings (e.g., actigraphy, melatonin profiling, ambulatory neuroimaging)
• Translational and comparative research using animal models to model chronobiological effects on cognitive control
• AI-augmented decision systems that adapt to user circadian profiles
• Chronotype impacts on clinical outcomes and medical decision-making
• Chronobiology in strategic and crisis decision-making (e.g., political or emergency scenarios)
• Circadian preferences in consumer choice and lifestyle decisions.

Topic editors

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

     

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
