83The electrophysiology of introspectionConsciousness and Cognition 15 (4): 662-672. 2006.To study whether the distinction between introspective and non-introspective states of mind is an empirical reality or merely a conceptual distinction, we measured event-related potentials elicited in introspective and non-introspective instruction conditions while the observers were trying to detect the presence of a masked stimulus. The ERPs indicated measurable differences related to introspection in both preconscious and conscious processes. Our data support the hypothesis that introspective…Read more

12Ontogenetic emergence as a criterion for theories of consciousness: Comparing GNW, SOMA, and REFCONPhilosophy and the Mind Sciences 4. 2023.In recent years increasing attention has been given to systematic comparison of theories of consciousness. Laudable practical projects have emerged in this regard, such as adversarial collaboration and the development of databases lending themselves to comparisons of empirical support for theories. In addition to the practical advances, theoretical advances have been made, such as a list of issues a theory of consciousness must address. We propose adding the issue of the ontogenetic emergence (O…Read more

8Methodological reductionism or methodological dualism? In search of a middle groundPhenomenology and the Cognitive Sciences 1-14. forthcoming.The contrasts between so-called objective and subjective measures of consciousness have been a dominating topic of discussion for decades. The debate has classically been dominated by two positions – that subjective measures may be completely or partially reduced to objective measures, and, alternatively that they must exist in parallel. I argue that many problems relate to subjective reports as they can be imprecise and vulnerable to a number of potential confounding factors. However, I also ar…Read more

29Multiple Factors and Multiple Mechanisms Determine the Quality of Conscious Experiences: A Reply to Anzulewicz and WierzchońCognitive Science 42 (6): 2101-2103. 2018.In this Letter to the Editor, we seize the opportunity to respond to the recent comments by Anzulewicz and Wierzchoń, and further clarify and extend the scope of our original paper. We re‐emphasize that conscious experiences come in degrees, and that there are several factors that determine this degree. Endorsing the suggestions of Anzulewicz and Wierzchoń, we discuss that besides low‐level attentional mechanisms, high‐level attentional and non‐attentional mechanisms might also modulate the qual…Read more

38A Multi‐Factor Account of Degrees of AwarenessCognitive Science 42 (6): 1833-1859. 2018.In this paper we argue that awareness comes in degrees, and we propose a novel multi-factor account that spans both subjective experiences and perceptual representations. At the subjective level, we argue that conscious experiences can be degraded by being fragmented, less salient, too generic, or flash-like. At the representational level, we identify corresponding features of perceptual representations—their availability for working memory, intensity, precision, and stability—and argue that the…Read more

6Beyond Neural Correlates of ConsciousnessRoutledge. 2020.Drawing on neuroscientific research and metacognitive theory, this ground-breaking volume examines the theoretical implications that are elicited when neural correlates of consciousness are identified. The relationship between consciousness and the brain has concerned philosophers for centuries, yet a tacit assumption in much empirically-minded consciousness research seems to be that if we can only develop a map of correlations, no further questions remain to be asked. Beyond Neural Correlates o…Read more

65An integration of first-person methodologies in cognitive scienceJournal of Consciousness Studies 15 (5): 100-120. 2008.A number of recent publications have argued that a scientific approach to consciousness needs a rigorous approach to first-person data collection. As mainstream experimental psychology has long abandoned such introspective or phenomenological method, there is at present no generally agreed upon method for first-person data collection in experimental consciousness studies. There are, however, a number of recent articles that all claim to provide a unique contribution to such a methodology. This a…Read more

93Is conscious perception gradual or dichotomous? A comparison of report methodologies during a visual taskConsciousness and Cognition 15 (4): 700-708. 2006.In a recent article, [Sergent, C. & Dehaene, S. . Is consciousness a gradual phenomenon? Evidence for an all-or-none bifurcation during the attentional blink, Psychological Science, 15, 720–729] claim to give experimental support to the thesis that there is a clear transition between conscious and unconscious perception. This idea is opposed to theoretical arguments that we should think of conscious perception as a continuum of clarity, with e.g., fringe conscious states [Mangan, B. . Sensation’…Read more

48Partial awareness distinguishes between measuring conscious perception and conscious content: Reply to Dienes and SethConsciousness and Cognition 19 (4): 1081-1083. 2010.In their comment on Sandberg, Timmermans, Overgaard, and Cleeremans , Dienes and Seth argue that increased sensitivity of the Perceptual Awareness Scale is a consequence of the scale being less exclusive rather than more exhaustive. According to Dienes and Seth, this is because PAS may measure some conscious content, though not necessarily relevant conscious content, “If one saw a square but was only aware of seeing a flash of something, then one has not consciously seen a square.” In this reply…Read more

2Visual experience and blindsight: A methodological reviewExperimental Brain Research 209 473-479. 2011.Blindsight is classically defined as residual visual capacity, e.g., to detect and identify visual stimuli, in the total absence of perceptual awareness following lesions to V1. However, whereas most experiments have investigated what blindsight patients can and cannot do, the literature contains several, often contradictory, remarks about remaining visual experience. This review examines closer these remarks as well as experiments that directly approach the nature of possibly spared visual expe…Read more

26On the encompassing of the behaviour of manBehavioral and Brain Sciences 26 (5): 615-616. 2003.One supposition underlying the Anderson & Lebiere target article is that the maximally broad “encompassing of its subject matter – the behavior of man” is regarded as an unquestioned quality criterion for guiding cognitive research. One might argue for an explicit specification of the limitations of a given paradigm, rather than extending it to apply to as many domains as possible

111Measuring consciousness: Is one measure better than the other?Consciousness and Cognition 19 (4): 1069-1078. 2010.What is the best way of assessing the extent to which people are aware of a stimulus? Here, using a masked visual identification task, we compared three measures of subjective awareness: The Perceptual Awareness Scale , through which participants are asked to rate the clarity of their visual experience; confidence ratings , through which participants express their confidence in their identification decisions, and Post-decision wagering , in which participants place a monetary wager on their deci…Read more
