One of the most compelling questions still unanswered in neuroscience is how consciousness arises. In this article, we examine visual processing, the parietal lobe, and contralateral neglect syndrome as a window into consciousness and how the brain functions as the mind and we introduce a mechanism for the processing of visual information and its role in consciousness. We propose that consciousness arises from integration of information from throughout the body and brain by the thalamus and that the thalamus reimages visual (...) and other sensory information from throughout the cortex in a default three-dimensional space in the mind. We further suggest that the thalamus generates a dynamic default three-dimensional space by integrating processed information from corticothalamic feedback loops, creating an infrastructure that may form the basis of our consciousness. Further experimental evidence is needed to examine and support this hypothesis, the role of the thalamus, and to further elucidate the mechanism of consciousness. (shrink)

In this paper we list the various criticisms that have been formulated against introspection, from Auguste Comte denying that consciousness can observe itself, to recent criticisms of the reliability of first person descriptions. We show that these criticisms rely on the one hand on poor knowledge of the introspective process, and on the other hand on a naïve conception of scientific objectivity. Two kinds of answers are offered: the first one is grounded on a refined description of the process of (...) becoming aware of one's experience and describing it, the second one relies on a comparison with the methods of the experimental sciences. We conclude the article by providing a renewed definition of 'the truth' of a first person description. (shrink)

Descriptive Experience Sampling (DES) attempts to apprehend in high fidelity pristine inner experience (the naturally-occurring, directly-apprehended phenomena that fill our waking lives, including inner speaking, visual imagery, sensory awarenesses, etc.). Previous DES investigations had shown individual differences in the frequency of inner speaking ranging from nearly zero to nearly 100% of the time. In early 2020, the Internet was ablaze with comments expressing astonishment that constant internal monologue was not universal. We invited Lena, a university student who believed she had (...) constant internal monologue, to participate in a DES analog of a pre-registered study: We would announce, on the Internet, that we would conduct a fully transparent DES investigation and roll out videos of the DES interviews (and annotated transcripts) as they occurred in (almost) real-time, something like “reality TV about inner experience,” so that spectators could examine for themselves our characterizations of Lena and how we arrived at them. We describe here the procedure and its findings: Lena did _not_ have frequent internal monologue (contrary to her expectations); she _did_ have frequent visual imagery (to her surprise); and we speculated about the frequent presence of two simultaneous “centers of gravity” of her experience. The entire procedure is available for inspection. (shrink)

Underlying the recent focus on embodied and interactive aspects of social understanding are several intuitions about what roles the body, interaction processes, and interpersonal experience play. In this paper, we introduce a systematic, hands-on method for investigating the experience of interacting and its role in intersubjectivity. Special about this method is that it starts from the idea that researchers of social understanding are themselves one of the best tools for their own investigations. The method provides ways for researchers to calibrate (...) and to trust themselves as sophisticated instruments to help generate novel insights into human interactive experience. We present the basics of the method, and two empirical studies. The first is a video-study on autism, which shows greater refinement in the way people with autism embody their social interactions than previously thought. The second is a study of thinking in live interactions, which provides insight into the common feeling that too much thinking can hamper interaction, and into how this kind of interactional awkwardness might be unblocked.
