Does post-event cognitive load undermine thought suppression and increase intrusive memories after exposure to an analogue stressor?

Ironic process theory has been used in part to explain the phenomenon of intrusive memories in various disorders including post-traumatic stress disorder. How thought suppression interacts with other cognitive processes believed to be instrumental in the development of traumatic intrusive memory was tested. In an analogue design 120 participants were randomised to five conditions, four of which also required participants to attempt to suppress intrusive memories after viewing a film of traumatic content. Participants in three conditions were also required to perform concurrent tasks that acted as a cognitive load during suppression. Intrusive memories were recorded during the experimental phase and at 1-week follow-up. Contrary to predictions, post-film processing did not undermine suppression success. There was some suggestion that post-film processing resulted in those participants experiencing intrusions of shorter duration than the no-suppression control group in two 5-minute intrusion monitoring intervals at the initial and follow-up phase of the experiment, but this was not reflected in a 1-week diary measure of intrusions. All experimental groups performed in a similar fashion in terms of memory testing of the film's content. The findings are discussed in the context of ironic process theory and cognitive models of post-traumatic stress.     

Metametaphysics and Substance: Two Case Studies

This paper examines an often-ignored aspect of the evaluation of metaphysical analyses, namely, their ontological commitments. Such evaluations are part of metaphysical methodology, and reflection on this methodology is itself part of metametaphysics. I will develop a theory for assessing what these commitments are, and then I will apply it to an important historical and an important contemporary metaphysical analysis of the concept of an individual substance (i.e., an object, or thing). I claim that in evaluating metaphysical analyses, we should not only rule out counterexamples, but also compare them with respect to their ontological commitments, and we should hold that if they are comparable in other respects, then an analysis with fewer such commitments is preferable to one with more (There is, of course, a connection between counterexamples and ontological commitments. If the existence or possible existence of something one is committed to the existence or possible existence of is incompatible with an analysis, then one should reject that analysis as inadequate to the data. On the other hand, if one is uncertain about the existence or possible existence of something that is incompatible with an analysis, then while this does not refute the analysis for one, it raises doubts about it. The fewer such doubts are raised by an analysis, the better it is.).     

Behavioral community psychology: training a community board to problem solve

This study demonstrated the effect of training nine lower socio-economic adults participating as policy board members in a federally funded rural community project to make behaviorally defined statements to increase problem-solving behaviors in board meetings. A multiple-baseline design across subjects and skills was used to analyze the behavioral categories of: (1) stating the problem; (2) finding solutions to the problem, and (3) implementing the action to the solution. Problem-solving responses during board meetings increased for subjects following training and remained higher than baseline during follow-up.     

War,revolution, and psychoanalysis: Freudian thought begins to grapple with social reality

Psychoanalytic theory and practice have been affected by external events as well as by internal development. Specifically, the period of the Great War and its aftermath was a turning point in the history of psychoanalysis. These experiences emphasized the inadequacy of the libido theory alone, accelerated Freud's impetus toward metapsychology, and encouraged the articulation of theories of innate destructive urges, of ego instincts, of the superego, and of social interaction. Discussionsof war neuroses, of aggression and the death instinct, of the reality principle, and of the mechanisms of social psychology undermined Freud's original biologism in favor of a social-scientific approach. Psychoanalytic theory began to take more account of social experience and was profoundly changed in the process.     

The perception of color from motion

We introduce and explore a color phenomenon which requires the prior perception of motion to produce a spread of color over a region defined by motion. We call this motion-induced spread of colordynamic color spreading. The perception of dynamic color spreading is yoked to the perception of apparent motion: As the ratings of perceived motion increase, the ratings of color spreading increase. The effect is most pronounced if the region defined by motion is near 1° of visual angle. As the luminance     

Empathy and justice motivation

Empathic distress is defined as an aversive feeling contingent on another's physical, emotional, or economic distress. The paper (1) summarizes a developmental scheme consisting of four stages of empathic distress; (2) suggests that causal attributions may partly transform empathic distress into sympathy, empathic anger, feeling of injustice, and guilt feeling; (3) notes the evidence that these empathic affects often serve to motivate moral behavior, and therefore that they qualify as moral motives; (4) points up limitations of these affects/motives and the need to embed them in justice principles; (5) discusses links between empathic affects/motives and principles of distributive justice/ (6) argues that Rawls' theory of justice, which excludes empathy, may nevertheless require it for the difference principle to influence behavior in real life; (7) hypothesizes a functional equivalence between empathy and the veil of ignorance; and (8) speculates that the conjunction of empathic affect and justice-principle thinking — in life and in abstract didactic contexts like Rawls' original position — may produce a principle having the motivational and stabilizing properties of a hot cognition.
