The paper evaluates a well‐known argument for a self from episodic memories—that remembering that I did something or thought something involves experiencing the identity of my present self with the past doer or thinker. Shaun Nichols argues that although it phenomenologically appears to be the case that we are identical with the past self, no metaphysical conclusion can be drawn from the phenomenology. I draw on literature from contemporary psychology and Buddhist resources to arrive at a more radical conclusion: that (...) there is no phenomenological sense of identity with a past self; the sense of self in episodic memory depends on narrative construction of the self.

Many sophisticated essays and books have been written about the topic of consciousness. My own contributions date back some twenty-five years in an essay entitled 'Problems concerning the structure of consciousness' (Pribram 1976), and five years before that in delineating the difference between brain processes that are coordinate with awareness and those that are coordinate with habitual behavior (Pribram 1971a). I have been intrigued by what has been written since and take this occasion to reassess a few of the major (...) issues that have arisen. (shrink)

The goal of this study is to characterize observers’ abilities to discriminate between endogenous and exogenous changes. To do so, we developed a new experimental paradigm. On each trial, participants were shown a dot pattern on the screen. Next, the pattern disappeared and participants were to reproduce it. Changes were surreptuously introduced in the stimulus, either by presenting participants anew with the dot pattern they had themselves produced on the previous trial or by presenting participants with a slightly different dot (...) pattern . We analyzed awareness of the changes and behavioral adaptation to them in a dynamical manner. We observe signal attenuation in the presence of endogenous change, dissociation between self-attribution reports and behavioral effect of agency. We discuss the source of this sensitive attenuation as well as the relation between a minimal or core self and an extended, narrative or autobiographical self. (shrink)

In this introductory paper, we assess the current status of blindsight -- the phenomenon in which patients with damage to their primary visual cortex retain the ability to detect, discriminate and localize visual stimuli presented in areas of their visual field in which they report that they are subjectively blind. Blindsight has garnered a great deal of interest and critical research, in part because of its important implications for the philosophy of mind. We briefly consider why this is so, and (...) then go on to examine three empirical questions which have fuelled challenges to the validity of blindsight as a distinct neuropsychological phenomenon. First, is blindsight simply degraded normal vision? Second, does blindsight depend on undamaged areas of primary visual cortex? Third, does evidence that blindsight patients are aware of moving stimuli undermine the apparent dissociation between access to visual information and visual experience in blindsight? In the course of the review we introduce the four other papers on blindsight in this issue. We conclude that, although patients with primary visual cortex damage may indeed perceive moving stimuli, there is still good evidence for a dissociation between access to information and phenomenal experience which cannot be accounted for in terms of degraded normal vision or undamaged primary visual cortex.

The temporal orientations of any sociocultural grouping are major factors comprising its central identity. The manner in which the past (memories), the present (perception), and the future (anticipation/expectation) are commonly articulated also concern cultural identity. The identity of a cultural group is altered by developmental changes in time keeping and related objective, scientific temporalities.Three modes of temporality, objective, narrative, and transcendental, congruent with different kinds of brain processes, are common throughout our planet. Objective temporality tends to alter and replace traditional (...) narrative and transcendental (spiritual) time, timing, and tempos. Objective temporality is concerned with what is transitory, modern and “progressive”. Objective time is not a traditional form of cultural time; it is a derived Westernized scientific imposition, rather than any cultural formation. This essay develops a new conception of how semiosis occurs. All information is essentially rhythmic, transduced through sensory systems as signals in a space-time domain, but deposited for use into a spectral thermodynamic domain in the human cortex.A “chronemic” perspective, (temporality as it is based in semiotic processes related to human communication) is assumed throughout. Such a perspective appears to be somewhat novel in both communication and semiotic studies. (shrink)
