Harnessing psychoanalytical methods for a phenomenological neuroscience

Psychoanalysis proffers a wealth of phenomenological tools to advance the study of consciousness. Techniques for elucidating the structures of subjective life are sorely lacking in the cognitive sciences; as such, experiential reporting techniques must rise to meet both complex theories of brain function and increasingly sophisticated neuroimaging technologies. Analysis may offer valuable methods for bridging the gap between first-person and third-person accounts of the mind. Using both systematic observational approaches alongside unstructured narrative interactions, psychoanalysts help patients articulate their experience and bring unconscious mental contents into awareness. Similar to seasoned meditators or phenomenologists, individuals who have undergone analysis are experts in discerning and describing their subjective experience, thus making them ideal candidates for neurophenomenology. Moreover, analytic techniques may provide a means of guiding untrained experimental participants to greater awareness of their mental continuum, as well as gathering subjective reports about fundamental yet elusive aspects of experience including selfhood, temporality, and inter-subjectivity. Mining psychoanalysis for its methodological innovations provides a fresh turn for the neuropsychoanalysis movement and cognitive science as a whole – showcasing the integrity of analysis alongside the irreducibility of human experience.


INTRODUCTION
This paper illustrates how the marriage of phenomenology and psychoanalysis can inform the scientific study of consciousness. In particular, we outline the potential psychoanalysis holds as a tool for fostering different states of awareness and gathering experiential accounts for the purposes of cognitive neuroscience. Methods for elucidating the structures of phenomenal experience are scantily present in the landscape composing the cognitive sciences. This lacuna -a palpable gap between subjective and objective techniques -calls for expert methods to discern and describe experience from first and second person perspectives. While readily embracing psychodynamic theory, proponents of the neuropsychoanalysis movement have largely overlooked the methods inherent to analysis. A central aspect of the psychoanalytic approach, the unstructured narrative interaction forms the backbone of analysis. Though unconventional in the context of experimental neuropsychology, to disparage the narrative dynamic would cripple the research potential of psychoanalysis (Bazan, 2011). For example, cognitive scientists stand to benefit from narrative approaches to guide participants to uncover unconscious aspects of their experience, cultivate meta-awareness, and elicit descriptive firsthand reports. Here we argue that viewing psychoanalysis as a method for elucidating subjective experience best motivates collaboration between neuroscience and psychoanalysis. Sketching the crux of contemporary neuropsychoanalysis, we highlight the relative merits of a crosstalk with the critical neuroscience movement of neurophenomenology. We conclude by discussing how the development of new phenomenological techniques may leverage psychoanalytic methods in the clinical and experimental study of consciousness.

NEUROPSYCHOANALYSIS IN FLUX
Neuroscientists, as well as psychoanalysts, are still trying to determine the nature of their collaboration in the burgeoning field of neuropsychoanalysis. Controversy regarding the relationship between psychoanalysis and the natural sciences dates back to Freud's time, and continues to garner much attention today (Cohler and Galatzer-Levy, 2007). While some scholars consider neurobiology and psychoanalysis to be epistemologically and terminologically irreconcilable (Borch-Jacobsen and Shamdasani, 2011), the organic basis of mental life is one of the founding tenets of psychoanalysis (e.g., Freud, 1910b, p. 209). Freud (1895) had anticipated a future in which the psychological and neural sciences would coalesce. Since the 1990s, this vision has gradually come to fruition: while neuroscientists and cognitive psychologists have rekindled their interest in psychoanalytic ideas, analysts have increasingly turned toward the biological sciences (Fotopoulou et al., 2012). Overarching arguments continue to suggest that neuropsychoanalysis binds neuroscience and analysis by facilitating a crosstalk on topics of mutual interest (Solms and Turnbull, 2011). These global accounts inspire leading contemporary scholars to follow this intuitive lead and expound on the details of this cooperation.

Most research under the label of "neuropsychoanalysis" seeks to situate the concepts of psychoanalysis within the framework of contemporary neuroscience. Early collaboration, in the spirit of Freud, centered on understanding neuropathology from a psychodynamic perspective (Kaplan- Solms and Solms, 2000). This manner of clinically oriented investigation has since expanded to include studies of pathological behavior (e.g., depression and anxiety, Zellner et al., 2011), the neural mechanisms of psychodynamic psychotherapy (Gerber, 2011), as well as attempts to find biological measures for therapeutic outcomes (Shedler, 2010). Other research in neuropsychoanalysis fits with the preclinical cognitive neuroscience of consciousness. These investigations aim to develop models of the brain that accommodate and illuminate psychoanalytic phenomena such as repression (Bazan and Snodgrass, 2012), libido (Pfaff and Fisher, 2012), the dynamic unconscious (Shevrin et al., 1996;Berlin, 2011;Solms and Zellner, 2012), and dreaming (Zellner, 2013). As the investigatory domain of contemporary neuropsychoanalysis grows, so does the variety of empirical approaches: from neuroimaging techniques to experimental behavioral methods and animal studies (Fotopoulou et al., 2012).
Some analysts view neuropsychoanalysis as a weight on psychoanalytic discourse. Such clinicians see the movement as perpetuating the view that psychoanalysis needs biological bolstering to be complete, legitimate, and relevant (Blass and Carmeli, 2007). Other scholars have been especially critical of neuropsychoanalysis, suggesting that it could taint quality, and understanding of analysis among clinicians (Hoffman, 2009). These claims likely emerge in response to studies that purport to investigate the "scientific validity" of psychoanalytic theories (cf dream theory in Shirley, 2011). Alas, such scientism runs counter to the very epistemology set forth by the founders of neuropsychoanalysis, who encourage a balance between scientific objectivity and the subjective insights of psychoanalysis (Fotopoulou et al., 2012). Other critics argue that neuroscience is irrelevant to clinical practice, as the latter emphasizes uniquely personal accounts that are scantily amenable to scientific generalization (Pulver, 2003;Mechelli, 2010). Proponents of neuropsychoanalysis typically respond that while the entire spectrum of neuroscientific studies may be less clinically relevant to psychoanalysts, some studies undoubtedly are, for example animal studies that shed light on primal emotional behavior (Panksepp and Solms, 2012). And while concerns about the integrity of clinical practice remain an important issue, analysts also warn against an insular psychoanalysis that fails to engage in a constructive and critical dialog with the larger scientific community (Safran, 2012).
The collaboration between neuroscience and psychoanalysis reflects greater questions about the nature of scientific research, discourse, and validation (Aron, 2012). By incorporating phenomenological domains into traditional experimental paradigms, neuropsychoanalysis are reshaping the boundaries of science. Findings from neuroscience, moreover, increasingly govern our popular conceptions concerning behavior, psychopathology, and what it means to be human (Thornton, 2011;Young, 2011). Neuropsychoanalysis, therefore, joins the critical neuroscience movement in engaging the scientific community with discussions about culture, meaning, and the irreducibility of human experience (Choudhury and Slaby, 2011). Within this overarching search to unravel the relationship between the mind and body, a central question looms: can the objective third-person methods of cognitive science account for the first-person experience of subjective mental life?

NEUROPHENOMENOLOGY AND THE PROBLEM OF CONSCIOUSNESS
The question of how and why humans are consciousknown amongst philosophers as the "hard problem" of consciousness -has provoked major debate concerning the nature of scientific inquiry. Most scientists posit that biological mechanisms subserve conscious experience, albeit little knowledge informs the details of such mechanisms (Chalmers, 1995(Chalmers, , 2002. Neurologists have long recognized that we seem able to account for the workings of the human brain without recourse to influences beyond the laws of physical science (Eccles, 1965). Subsequently, many thinkers feel hard-pressed to speculate on the evolutionary and functional role of consciousness (Harnad, 2002). Such questions have led some philosophers to the conclusion that consciousness is an illusory heuristic (Churchland, 1981). These thinkers argue that conscious experience just is the neurobiological correlate of consciousness -a position that most neuroscientists hold as their "spontaneous philosophy" (Varela, 1998, p. 31;Dennett, 2001). Others disagree and argue that a description of mind that refers only to biological substrates and processes necessarily leaves something out. These scholars insist that consciousness is irreducible to information processing in the brain (Velmans, 2009) and emphasize that our conscious experience presupposes "every statement, model, or theory" of natural science (Thompson, 2004, p. 394). Such philosophical discord persists, reflecting and motivating practical challenges in the study of consciousness at the experimental level.
One response to the puzzle of consciousness comes from neurophenomenology, a movement founded by Varela et al. (1992). According to Varela, the hard problem is established on a deeply ingrained, falsely dualistic understanding of mind and brain. Instead of trying to philosophically "solve" the hard problem, he proposed that cognitive scientists take a methodological approach (Varela, 1996). In order to elucidate how and why experiences arise from neural processes, scientists require careful descriptions of experience to match the refined objective descriptions of brain functioning (Jack and Shallice, 2001;Lutz, 2002); however, researchers have largely eschewed such first-person methods. This trend partly owes to the recent focus in cognitive science on imaging of the living human brain alongside a long-standing ambivalence towards introspective reports (Nisbett and Wilson, 1977). Thus, while researchers are now equipped with many advanced methods for imaging and modeling the brain in fine-grained detail, sophisticated methods for describing and discriminating subjective experience continue to lag behind. Varela advocated bridging this methodological gap by incorporating the experiential techniques of phenomenology into a circulating dialog with the third-person methods of cognitive science. His neurophenomenology seeks to give an "explicit and central role Frontiers in Psychology | Psychoanalysis and Neuropsychoanalysis to first-person accounts and to the irreducible nature of experience, while at the same time refusing both a dualistic concession or a pessimistic surrender" (Varela, 1998, p. 32). In doing so, neurophenomenology does not solve, but rather "dis-solves" the hard problem (Varela, 1998).
Proponents of Varela have realized the neurophenomenological project in different forms and under a variety of labels. Some scholars focus on the philosophical details of the collaboration between phenomenology and cognitive science (Gallagher, 2003). These theorists tease apart difficult phenomenological issues, such as the nature of indexing the self (Zahavi and Roepstorff, 2011), and conducting investigations into experiential realms pertinent to clinicians, including the phenomenology of psychopathology, (e.g., Sass et al., 2011). Neurophenomenology is also a growing scientific research program that seeks to modify and complement traditional methods of neuroscience for better phenomenological inquiry. For example, cognitive scientists have adapted a neuroimaging paradigm to allow for periodic "experience sampling" of subjects during experiments (Christoff et al., 2009). Some investigators utilize experimental participants who are already expert at observing and describing their experience, such as Buddhist meditators (Farb et al., 2007;Lutz et al., 2008). Other scholars have proposed that researchers may harness hypnotic and posthypnotic suggestion to alter subjective experience and encourage particular states of awareness (Lifshitz et al., 2013(Lifshitz et al., , 2014. One group of researchers in neurophenomenology focuses on developing firstperson methods (Depraz et al., 2003;Vermersch, 2009) as well as second-person interviewing techniques for aiding subjects in attending to and articulating their experience (e.g., Petitmengin, 2006). Across all approaches, both theoretical and applied neurophenomenologists aim to bind first-person approaches with the techniques of modern cognitive science to uncover the basic structures of consciousness (Gallagher and Schmicking, 2010).
Psychoanalysis seems apposite to the goals of neurophenomenology; yet neurophenomenologists have largely overlooked psychoanalytic techniques and theories. Instead, neurophenomenologists have turned to two main sources of inspiration: Western Phenomenology (e.g., following philosophers such as Heidegger, Husserl, and Merleau-Ponty; see Schmicking, 2010) and Eastern contemplative traditions including Buddhist practices (Thompson, 2006;Schmicking, 2010). Research in neurophenomenology centers on training or guiding participants to discern and describe their experience with awareness and impartiality (Petitmengin and Bitbol, 2011). The neurophenomenology approach encourages individuals to reflexively observe consciousness from their firstperson perspective and to recount accurate and detailed subjective reports (Lutz and Thompson, 2003). Although the inclusion of psychoanalysis in the neurophenomenological toolbox has yet to occur, Western Phenomenology, and psychoanalytic theory do overlap (Karlsson, 2010;Csordas, 2012). Indeed, the existential psychiatry movement of the early 20th century bridged the two disciplines in letter as well as in spirit (Halling and Dearborn Nill, 1995). Moreover, current efforts in neurophenomenology such as the "explicitation interview" harken to psychoanalytic techniques. The explicitation interview is a practice of "guided retrospective introspection" that incorporates inter-subjective guidance and non-leading suggestions to promote awareness of processes that typically remain implicit and un-seen within the field of experience, also known as "meta-awareness" (Maurel, 2009;Vermersch, 2009). Similarly, analysts describe the therapeutic process as "making the unconscious conscious" and commonly gage the completion of analysis by when the patient can freely articulate whatever comes to mind (Freud, 1910a;Wachtel, 2012). Thus, psychodynamic methods already suffuse established neurophenomenological protocols for cultivating meta-awareness in untrained participants.
The motives and objectives of neurophenomenology resonate with the call to neuropsychoanalysis. Both movements point to the need for a psychological theory in neuroscience that avoids fracturing or reducing human experience into a collection of functions and abilities. Just as neurophenomenologists emphasize the "embodied mind" (Clark, 1999;Thompson and Varela, 2001), neuropsychoanalysts urge scholars to reimagine the "minded brain" (Panksepp and Solms, 2012). Both groups argue that without a theoretical framework that operates at the level of the subject, neuropsychology fails to capture the psychological at all (Bazan, 2011), as well as stress the need for a "neurophenomenal level of analysis" in experimental neuropsychology (Panksepp and Solms, 2012). Like its phenomenological counterpart, neuropsychoanalysis can be seen as a direct effort against the implicit biological reductionism in cognitive neuroscience. Current research in the neuropsychoanalysis community appears biased toward the traditional methods of cognitive neuroscience. To analysts, collaboration with cognitive neuroscience runs the risk of reducing psychoanalytic "meaning" to neural "cause." In line with the outlook Varela espoused, a turn toward the methodological in neuropsychoanalysis could help assuage these concerns, shifting the emphasis from psychoanalytic theory (e.g., testing the scientific validity of psychoanalytic concepts) to psychoanalytic methods (e.g., incorporating technical aspects of the therapeutic process into experimental protocols). However, while both neurophenomenology and neuropsychoanalysis call for a theory of experience at the subject level, only the former has generated an empirical program for incorporating that theory in practice. In closing, therefore, we propose that neuropsychoanalysis may present a new incarnation of neurophenomenology.

CONCLUDING REMARKS
The practical realization of neuropsychoanalysis-as-neurophenomenology presents many challenges. For example, is it possible to harness elements of the intuitive therapeutic process in an experimental context? Whereas Varela called upon Western phenomenology and Eastern contemplative traditions for their systematic treatment of firsthand experience, analysts often cite one of the hallmarks of psychoanalysis as the "imprecise" treatment of firsthand experience (Bazan, 2011, p. 2). Written accounts of therapeutic methods (e.g., the specific strategies that an analyst employs to bring out the unconscious stories of their patients) tend to take the form of case studies. Descriptions of more universal or underlying therapeutic techniques are sparse; analysts train in vivo, by engaging in clinical internships and undergoing analysis themselves. While philosophers and analysts have www.frontiersin.org considered the mechanism of psychoanalytic insight and the relation between psychoanalytic insight and the structures of experience as described by cognitive and phenomenological science, these topics remain largely pristine on the proverbial "To Do" list of neuropsychoanalysis research (Strachey, 1934;Karlsson, 2010). And yet, phenomenology and psychoanalysis both draw on the premise that the vague nature of experience hardly precludes its careful articulation, analysis, and interpretation. A dialog between neuropsychoanalysis and neurophenomenology, therefore, would engender more precise ideas concerning the specific psychoanalytic techniques that can inform a correlation between firsthand descriptions of experience and third-person data.
One approach would advocate for including individuals who have undergone analysis as neurophenomenology participants. In the same way we treat seasoned meditators or phenomenologists, we can exploit the process of discerning and describing the psychoanalytic experience. This idea is scarcely new among analysts: "(One) might manipulate different neuropeptides, in research participants who are themselves psychoanalysts, and then have them describe their subjective states, using their expertise in doing so (with reference to the theoretical concepts that we use). Approaches such as this are rather radical, but they have huge potential, and appear to be remarkably underappreciated" (Solms and Turnbull, 2011, p. 9). To consider analysts and analysands experiential experts on par with, say, trained meditators raises many a problem. And yet, experiments involving either psychoanalytically trained individuals or Buddhist monks would both necessarily involve a second-person component -such as the explicitation interview -thereby exploiting a similar experimental approach.
Spanning an array of literature from clinical science and consciousness research, here we show how neurophenomenology casts a fresh light on the neuropsychoanalysis movement. While proponents of neuropsychoanalysis emphasize the importance of bringing a subject-oriented approach to cognitive neuroscience, these scholars have largely neglected the task of incorporating psychodynamic methods in an experimental setting. Cognitive scientists, however, stand to benefit from drawing on psychoanalytic techniques. Given their expertise in calling the unconscious mind to awareness, analysts could help researchers promote metaawareness and gather subjective reports that effectively describe the structures of experience. At the same time, focusing on the possibilities of methodological exchange between neuroscience and psychoanalysis offers an answer to concerns within the neuropsychoanalysis community. Rather than foisting neuroscientific methods and models onto the theories of psychoanalysis, mining analysis for its phenomenological capabilities would ensure the integrity of the psychodynamic identity in a domain increasingly tinged with neuro-reductionism. Such an approach would allow neuropsychoanalysis to flourish because of, rather than despite, the different perspectives of its comprising disciplines.
