Though emotional faces preferentially reach awareness, the present study utilised both objective and subjective indices of awareness to determine whether they enhance subjective awareness and “blindsight”. Under continuous flash suppression, participants localised a disgusted, fearful or neutral face (objective index), and rated their confidence (subjective index). Psychopathic traits were also measured to investigate their influence on emotion perception. As predicted, fear increased localisation accuracy, subjective awareness and “blindsight” of upright faces. Coldhearted traits were inversely related to subjective awareness, but not (...) “blindsight”, of upright fearful faces. In a follow-up experiment using inverted faces, increased localisation accuracy and awareness, but not “blindsight”, were observed for fear. Surprisingly, awareness of inverted fearful faces was positively correlated with coldheartedness. These results suggest that emotion enhances both pre-conscious processing and the qualitative experience of awareness, but that pre-conscious and conscious processing of emotional faces rely on at least partially dissociable cognitive mechanisms.

This study investigates the performance of psychopathic individuals on tasks believed to be sensitive to dorsolateral prefrontal and orbitofrontal cortex (OFC) functioning. Psychopathic and non-psychopathic individuals, as defined by the Hare psychopathy checklist revised (PCL-R) [Hare, The Hare psychopathy checklist revised, Toronto, Ontario: Multi-Health Systems, 1991] completed a gambling task [Cognition 50 (1994) 7] and the intradimensional/extradimensional (ID/ED) shift task [Nature 380 (1996) 69]. On the gambling task, psychopathic participants showed a global tendency to choose disadvantageously. Specifically, they showed an (...) impaired ability to show learning over the course of the task. On the ID/ED task, the performance of psychopathic individuals was not significantly different from incarcerated controls on attentional set-shifting, but significant impairments were found on response reversal. These results are interpreted with reference to an OFC and amygdala dysfunction explanation of psychopathy. (shrink)
This study investigates the ability of individuals with psychopathy to perform passive avoidance learning and whether this ability is modulated by level of reinforcement/punishment. Nineteen psychopathic and 21 comparison individuals, as defined by the Hare Psychopathy Checklist Revised (Hare, 1991), were given a passive avoidance task with a graded reinforcement schedule. Response to each rewarding number gained a point reward specific to that number (i.e., 1, 700, 1400 or 2000 points). Response to each punishing number lost a point punishment specific (...) to that number (i.e., the loss of 1, 700, 1400 or 2000 points). In line with predictions, individuals with psychopathy made more passive avoidance errors than the comparison individuals. In addition, while the performance of both groups was modulated by level of reward, only the performance of the comparison population was modulated by level of punishment. The results are interpreted with reference to a computational account of the emotional learning impairment in individuals with psychopathy. (shrink)
This study investigated the performance of boys with psychopathic tendencies and comparison boys, aged 9 to 17 years, on two tasks believed to be sensitive to amygdala and orbitofrontal cortex func- tioning. Fifty-one boys were divided into two groups according to the Psychopathy Screening Device (PSD, P. J. Frick & R. D. Hare, in press) and presented with two tasks. The tasks were the gambling task (A. Bechara, A. R. Damasio, H. Damasio, & S. W. Anderson, 1994) and the Intradimensional/ (...) Extradimensional (ID/ED) shift task (R. Dias, T. W. Robbins, & A. C. Roberts, 1996). The boys with psychopathic tendencies showed impaired performance on the gambling task. However, there were no group differences on the ID/ED task either for response reversal or extradimensional set shifting. The implications of these results for models of psychopathy are discussed.

Working in ZF + DC with no additional use of the axiom of choice, we show how to iterate the extended ultrapower construction of Spector . This generalizes the technique of iterated ultrapowers to choiceless set theory. As an application, we prove the following theorem: Assume V = LU[κ] + “κ is λ-supercompact with normal ultrafilter U” + DC. Then for every sufficiently large regular cardinal ρ, there exists a set-generic extension V[G] of the universe in which there exists for (...) some σ a set S ρ for which one can define an elementary embedding j mapping V to LD[S], where D is the filter in V[G] generated by the closed unbounded filter on ρ. Moreover, we have j = ρ, j = σ, j) = S according to LD[S]), and j = D ∩ LD[S] i s a normal ultrafilter in LD[S] on ρ. (shrink)
Balance and common sense are commonplace concepts used to bring an audience to a place of shared understanding. These commonplaces also function as decision-making heuristics. I argue in this paper that the commonplaces ?balance? and ?common sense? are problematic because they suggest decision-making strategies that strip associated information of complexity and value. Through an examination of theory and responses to interviews conducted in relation to an ongoing project on environmental rhetoric, I problematize these concepts and consider how awareness of the (...) interaction of these commonplaces and heuristics can benefit rhetors and agencies seeking environmental change.

This paper explores care ethics and the roles that power, trust, and stereotypes play in establishing and building caring relationships. The work is the result of the evolution of collaboration between teacher and student as that teacher/student dichotomy evolved to one of shared trust and respect and considers the oft-neglected aspect of respect in an ethic of care. By tracing the evolution of the authors’ relationship, we argue that mutual respect in an ethic of care has the potential to enrich (...) our interactions and reshape the way we think about care from primarily unilinear to a more reciprocal model. We propose a modified ethic of care based on mutual trust as a working model for ethics of care-based relationships, particularly with regard to student-teacher interactions, but also perhaps to more broadly extend into our daily interactions with others.

This book attempts, through a series of interpretive discussions, to confront a number of well-known perplexities in their structural form of disjunctive moments, of interpretive contexts of 'this is' and 'this is not.'.
The Bungle Book presents a demythology of six salient concepts central to our modern self-understanding, The “suspects” of the self, the machine, and God, as well as the “senses” of home, love, and freedom are analyzed and put into conversation with the work of Gadamer, Heidegger, Lingis, and Midgely.
What does place mean for human beings? What does it mean to exist in space? How do we place ourselves not only in physical space, but within the interior landscape of consciousness? Place Meant explores these and related questions through the lenses of psychoanalysis, sociology, geography, folklore, and history.
