This article re-examines the role of the brain in self-recognition. It reconsiders the idea that the frontal and cortical midline structures are important for self-specific experience in light of several recent reviews of neuroscience literature. The findings suggests that the frontal cortex and the cortical midline structure are not the only areas involved in self-related tasks and that these areas may be involved not because the tasks are self-specific, but because they are tasks that involve a specific kind of cognitive (...) operation, specifically reflective evaluation.

This paper explores the human significance of crack cocaine abuse by submitting its manifestation (logos) to existential-phenomenological analysis. The author conducted over fifty, first-hand interviews of recovering and active crack cocaine abusers toward disclosing the meaning of his to-be.What is revealed is the way the addiction reacts upon the with-structure of existence. Active crack cocaine addiction is being-high-and-free-of-craving. The singularity of this event eclipses the interhuman significance that substantially constitutes concern, as the meaning and Being of There-being, and radicalizes existence (...) such that the “other” is unceasingly projected as a means to free transcendence. The crack abuser forsakes the existentials being-with and There-being-with-others, ways of to-be that accommodate and gear into the existence of “others,” to being-with-crack, a way of Being that is exclusively for the sake of the dependent’s “self.”.

The self is a common yet unclear theme in addiction studies. William James's model of self provides a framework to explore the experience of self. His model details the subjective and objective constituents, the sense of self‐continuity through time, and the ephemeral and plural nature of the changing self. This exploration yields insights into the self that can be usefully applied to subjective experiences with psychoactive drugs of addiction. Results of this application add depth to the common understanding of self (...) in addiction, acknowledge the importance of feelings and choice in the sense of self created in addiction experiences, and affirm the values salient to these interior experiences in addiction. These results suggest meaning derived from those values, and provide important background knowledge for the nurse interacting with these clients. (shrink)

Knowledge concerning the relation of the addicted subject to time is deepened through a phenomenological analysis. The theoretical understanding of lived-time, or temporality, is explored with particular reference to the theories of Heidegger, Fuchs and van den Berg. Grounded in a description of the lived experiences of addicted persons, it is argued that the temporal relation of the addict is drawn, by the adoption of an addictive existence, primarily towards “the now” which predisposes the addict to various consequences. These include (...) impulsiveness, sleep disturbance, pain and social alienation. The relation of addiction to death is also briefly discussed in its temporal dimension. Implications for treatment and therapy are explored. (shrink)

The processing, representation, and perception of bodily signals (interoception) plays an important role for human behavior. Theories of embodied cognition hold that higher cognitive processes operate on perceptual symbols and that concept use involves reactivations of the sensory-motor states that occur during experience with the world. Similarly, activation of interoceptive representations and meta-representations of bodily signals supporting interoceptive awareness are profoundly associated with emotional experience and cognitive functions. This article gives an overview over present findings and models on interoception and (...) mechanisms of embodiment and highlights its relevance for disorders that are suggested to represent a translation deficit of bodily states into subjective feelings and self-awareness.

Although philosophical approaches to the self are diverse, several of them are relevant to cognitive science. First, the notion of a 'minimal self', a self devoid of temporal extension, is clarified by distinguishing between a sense of agency and a sense of ownership for action. To the extent that these senses are subject to failure in pathologies like schizophrenia, a neuropsychological model of schizophrenia may help to clarify the nature of the minimal self and its neurological underpinnings. Second, there is (...) good evidence to suggest that although certain aspects of the minimal self are primitive and embodied, other aspects may be accessed only in reflective consciousness. Employing a modified concept of the minimal self, it may be possible to construct a robotic form of non-conscious self-reference that depends on an interaction between the robotic body and its environment. In contrast to the minimal self, the narrative self involves continuity over time and is directly relevant to discussions of memory and personal identity. There is growing consensus among philosophers and cognitive scientists about the importance of narrative and its relation to episodic memory and left-hemisphere functions. There are, however, at least two different views of how the narrative self is structured. On one model it is nothing more than an abstract point. On a more extended view, proposed here, the self is a rich amalgam of narratives that allows for the equivocations, contradictions, and self-deceptions of personal life. Even in this case, however, neurocognitive models contribute to our understanding of how narrative identity is structured. (shrink)

We are even less aware of our internal organs and the physiological processes that keep us alive. In this fascinating work, Drew Leder examines all the ways in which the body is absent—forgotten, alien, uncontrollable, obscured.
