To understand the endogenous components of the event-related brain potential (ERP), we must use data about the components' antecedent conditions to form hypotheses about the information-processing function of the underlying brain activity. These hypotheses, in turn, generate testable predictions about the consequences of the component. We review the application of this approach to the analysis of the P300 component. The amplitude of the P300 is controlled multiplicatively by the subjective probability and the task relevance of the eliciting events, whereas its (...) latency depends on the duration of stimulus evaluation. These and other factors suggest that the P300 is a manifestation of activity occurring whenever one's model of the environment must be revised. Tests of three predictions based on this “context updating” model are reviewed. Verleger's critique is based on a misconstrual of the model as well as a partial and misleading reading of the relevant literature. (shrink)

Suppose that a team of neurosurgeons and bioengineers were able to remove your brain from your body, suspend it in a life-sustaining vat of liquid nutrients, and connect its neurons and nerve terminals by wires to a supercomputer that would stimulate it with electrical impulses exactly like those it normally receives when embodied. According to this brain-in-a-vat thought experiment, your envatted brain and your embodied brain would have subjectively indistinguishable mental lives. For all you know—so one argument goes—you could be (...) such a brain in a vat right now.1 Daniel Dennett calls this sort of philosophical thought experiment an “intuition pump” (Dennett 1995). An intuition pump is designed to elicit certain intuitive convictions, but is not itself a proper argument: “intuition pumps are fine if they’re used correctly, but they can also be misused. They’re not arguments, they’re stories. Instead of having a conclusion, they pump an intuition. They get you to say ‘Aha! Oh, I get it!’ (Dennett 1995, p. 182). Philosophers have used the brain-in-a-vat story mainly to raise the problem of radical skepticism and to elicit various intuitions about meaning and knowledge (Putnam 1981). The basic intuition the story tries to pump is that the envatted brain, though fully conscious, has systematically false beliefs about the world, including itself. Some philosophers reject this intuition. They propose that the envatted brain’s beliefs are really about its artificial environment or that it.. (shrink)

This paper describes a method for analyzing a corpus of descriptions collected through micro-phenomenological interviews. This analysis aims at identifying the structure of the singular experiences which have been described, and in particular their diachronic structure, while unfolding generic experiential structures through an iterative approach. After summarizing the principles of the micro-phenomenological interview, and then describing the process of preparation of the verbatim, the article presents on the one hand, the principles and conceptual devices of the analysis method and on (...) the other hand several dimensions of the analysis process: the modes of structural unfolding of generic structures, the mutual guidance of the processes of structural and experiential unfolding, the tracking of analysis processes, and finally the assessment of analysis results.

This article presents an interview method which enables us to bring a person, who may not even have been trained, to become aware of his or her subjective experience, and describe it with great precision. It is focused on the difficulties of becoming aware of one’s subjective experience and describing it, and on the processes used by this interview technique to overcome each of these difficulties. The article ends with a discussion of the criteria governing the validity of the descriptions (...) obtained, and then with a brief review of the functions of these descriptions. (shrink)

The purpose of this paper is to show through the concrete example of epileptic seizure anticipation how neuro-dynamic analysis and “pheno-dynamic” analysis may guide and determine each other. We will show that this dynamic approach to epileptic seizure makes it possible to consolidate the foundations of a cognitive non pharmacological therapy of epilepsy. We will also show through this example how the neuro-phenomenological co-determination could shed new light on the difficult problem of the “gap” which separates subjective experience from neurophysiological (...) activity.

Research in phenomenology has benefitted from using exceptional cases from pathology and expertise. But exactly how are we to generate and apply knowledge from such cases to the phenomenological domain? As researchers of cerebral palsy and musical absorption, we together answer the how question by pointing to the resource of the qualitative interview. Using the qualitative interview is a direct response to Varela’s call for better pragmatics in the methodology of phenomenology and cognitive science and Gallagher’s suggestion for phenomenology to (...) develop its methodology and outsource its tasks. We agree with their proposals, but want to develop them further by discussing and proposing a general framework that can integrate research paradigms of the well-established disciplines of phenomenological philosophy and qualitative science. We give this the working title, a “phenomenological interview”. First we describe the what of the interview, that is the nature of the interview in which one encounters another subject and generates knowledge of a given experience together with this other subject. In the second part, we qualify why it is worthwhile making the time-consuming effort to engage in a phenomenological interview. In the third and fourth parts, we in general terms discuss how to conduct the interview and the subsequent phenomenological analysis, by discussing the pragmatics of Vermersch’s and Petitmengin’s “Explicitation Interview”.

We concur with Sommer et al. that the processing manifested by P300 is not necessarily conscious. We also note that Verleger is yet again adducing evidence that contradicts an assertion we never made.

Linking the process of rational decision making to emotions, an award-winning scientist who has done extensive research with brain-damaged patients notes the dependence of thought processes on feelings and the body's survival-oriented regulators. 50,000 first printing.

Context: Despite the fact that pain and body awareness are by definition subjective experiences, most studies assessing these phenomena and the relationship between them have done so from a “third-person” perspective, meaning that they have used methods whose aim is to try to objectify the phenomena under study. Problem: This article assesses the question of what is the impact of a widespread chronic pain condition in the bodily experience of persons suffering from fibromyalgia. Method: I used an interview methodology stemming (...) from a phenomenological approach called the “elicitation interview.” Results: The results indicate that the intensification of fibromyalgia pain does in fact affect different aspects of body awareness: in particular, experienced body size, weight and localization, as well as the experience of owning one’s own body. In addition, these disruptions in patient’s body awareness have as a result, a modification of the experience of pain, leading to the apparently paradoxical experience of being in pain while not feeling it. Implications: The elicitation interview approach made it possible to gather and analyze descriptions of the bodily experience of persons suffering from fibromyalgia. This approach allowed the consideration of the hypothesis that the disruption of implicit knowledge of the topography of patients’ bodies prevents them from referring to the pain sensation in terms of its localization and intensity, transforming the sensation in a way that is experienced as paradoxical. Further studies should be conducted that focus on the interplay between attention, pain and body perception. Constructivist content: The study presented in this article is framed within the perspective that the study of conscious phenomena should consider a first-person perspective, which is in line with constructivist approaches.

Context: The founding idea of neurophenomenology is that in order to progress in the understanding of the human mind, it is indispensable to integrate a disciplined study of human experience in cognitive neuroscience, an integration which is also presented as a methodological remedy for the “hard problem” of consciousness. Problem: Does neurophenomenology succeed in solving the hard problem? Method: I distinguish two interpretations and implementations of neurophenomenology: a light or “mild” neurophenomenology, which aims at building correlations between first-person descriptions and (...) neural recordings, and tries to evaluate the validity of first-person descriptions through objective criteria; and a deep or radical neurophenomenology, which aims at investigating the process of co-constitution of the subjective and the objective poles, within lived experience, and tries to evaluate first-person descriptions through processual criteria. Results: While mild neurophenomenology does not solve the hard problem, radical neurophenomenology solves it by dissolving it. Exploring the early stages of phenomenal processes such as the emergence of a perception or an idea highlights: a dimension of experience where the separation usually perceived between the subjective and the objective poles vanishes; micro-actions that instant after instant create and support this process of co-constitution, which Varela called “enaction.” This involves on the one hand experiencing concretely the dissolution of the hard problem, and on the other hand verifying the theory of enaction in lived experience. Implications: Radical neurophenomenology is a research programme that enables us to investigate precisely the mutual unfolding of the subjective and objective poles, from its most primitive phases such as perceptual events, to its latest phases such as the co-construction of scientific objectivity and intersubjectivity.

This article is devoted to the description of the experience associated with listening to a sound. In the first part, we describe the method we used to gather descriptions of auditory experience and to analyse these descriptions. This work of explicitation and analysis has enabled us to identify a threefold generic structure of this experience, depending on whether the attention of the subject is directed towards the event which is at the source of the sound, the sound in itself, considered (...) independently from its source, the felt sound. In the second part of the article, we describe this structure. The third part is devoted to a discussion of these results and the paths they open up in various fields of theoretical and applied research. (shrink)

Context: Affective neuroscience has not developed first-person methods for the generation of first-person data. This neglect is problematic, because emotion experience is a central dimension of affectivity. Problem: I propose that augmenting affective neuroscience with a neurophenomenological method can help address long-standing questions in emotion theory, such as: Do different emotions come with unique, distinctive patterns of brain and bodily activity? How do emotion experience, bodily feelings and brain and bodily activity relate to one another? Method: This paper is theoretical. (...) It advances ideas for integrating neurophenomenology and affective neuroscience, and explains how this integration would allow progress on the above questions. Results: An integrated “affective neuro-physio-phenomenology” may help scientists understand whether discrete emotion categories come in different experiential varieties, which would in turn help interpret concomitant brain and bodily activity. It may also help investigate the bodily nature of emotion experience, including how experience relates to actual brain and bodily activity. Implications: If put into practice, the ideas advanced here would enrich the scientific study of emotion experience and more generally further our understanding of the relationship of consciousness and physical activity. The paper is speculative and its ideas need to be implemented to bear fruit. Constructivist content: This paper argues in favor of the neurophenomenological method, which is an offshoot of enactivism. (shrink)

Context: The use of first-person micro-phenomenological interviews and their productive interaction with third-person physiological data is a challenging and pressing issue in order to offer an effective and fruitful application of Varela’s neurophenomenological hypothesis. Problem: We aim at offering a generative method of analysis of first-person micro-phenomenological interviews using third-person physiological data. Our challenge is to describe this generative first-person analysis with the third-person physiological framework rather than put Varela’s hypothesis into practice in a generative way (as we did in (...) another paper. Method: The present contribution is a first pioneering study as far as the exposition of such an interactive generative methodology is concerned. It is also a new issue insofar as it deals with a case study, surprise in depression, that has not been thoroughly dealt with so far, either in philosophy or in psychopathology. Results: We show that the analysis of first-person data is an intrinsic generative one, insofar as new refined categories and multifarious circular micro- and macro-processes were discovered in the very process of analyzing. They provide the initial structural generic third-person description of surprise inherited both from philosophical phenomenological a priori categories and from the experimental startle setting with a refined micro-segmentation of the dynamic of the experience. Implications: Our article could be of interest to neurophenomenologists looking for an effective application and to researchers in quest of a method of analysis of first-person data. The present limitations are due to the still preliminary data-results we need to complete. Constructivist content: The article is directly linked to Varela’s neurophenomenological program and aims at extending and reforming it with a cardio-phenomenological approach. Keywords: First-person micro-phenomenological interviews, surprise, generative analysis of first-person data, depression, cardio-phenomenology, generative categories. (shrink)

Context: The current study of emotions is based on theoretical models that limit the emotional experience. The collection of emotional data is through self-report questionnaires, restricting the description of emotional experience to broad concepts or induced preconceived qualities of how an emotion should be felt. Problem: Are the emotional experiences responding exclusively to these concepts and dimensions? Method: Music was used to lead participants into an emotional experience. Then a micro-phenomenological interview, a methodology with a phenomenological approach, was used to (...) guide their descriptions. Results: The descriptions of emotional experiences revealed a temporal structure that could have a linear or circular development. Moreover the qualitative aspects disclosed that these experiences are characterized by corporal sensations and marked variations of emotional intensity. Additionally, the emotional experience was embodied. Implications: The emotional experience is a dynamic process in which bodily sensations take a primary role, allowing the identification of such emotions. The integration of these first-person features of emotional experience with third-person data could lead to a better understanding and interpretation of emotional processes. Constructivist content: This article highlights the need to integrate first-person and third-person methodologies to study and explain human behavior in a comprehensive manner. Key Words: Emotion, experience, micro-phenomenological interview, body, music, affective neuroscience. (shrink)
