Predictable and self-initiated visual motion is judged to be slower than computer generated motion

Self-initiated action effects are often perceived as less intense than identical but externally generated stimuli. It is thought that forward models within the sensorimotor system pre-activate cortical representations of predicted action effects, reducing perceptual sensitivity and attenuating neural responses. As self-agency and predictability are seldom manipulated simultaneously in behavioral experiments, it is unclear if self-other differences depend on predictable action effect contingencies, or if both self- and externally generated stimuli are modulated similarly by predictability. We factorially combined variation in (1) predictability of action effects, (2) spatial congruence, and (3) performance by the self or computer to dissociate these influences on a visual discrimination task. Participants performed 2AFC speed judgments. Self-initiated motion was judged to be slower than computer-initiated motion when action effect contingencies were predictable, while spatial congruence influenced speed judgments only when action effect contingencies were unpredictable. Results are discussed in relation to current theories of sensory attenuation.     

The functionalist theory of stratification: Two decades of controversy

The author examines the 1945 and 1948 versions of the Davis‐Moore functionalist theory of stratification. The analysis explores the basic postulates, assumptions, and logical articulation of the theory and isolates its distinctively functionalist components. This is followed by a historical account of the major criticisms leveled at the theory. The critics have succeeded in showing the fallacious and tautologous character of the functionalist components, thus, in effect, destroying the theory as a theory. Despite this destruction, various portions of the Davis‐Moore theory are shown to be usable, to contain valuable insights, and to be capable of further development.     

Postmodernism's Self-Nullifying Reading of Nietzsche

In his very rich and insightful book, Kant's Theory of Freedom, Henry Allison argues that in the first Critique Kant's reason for rejecting Humean compatibilism in favor of an incompatibilist conception of practical freedom stems, not from a specific concern to ground morality, as many have supposed, but from his general conception of rational agency, which Allison explicates in terms of the idea of practical spontaneity. Practically spontaneous rational agency is subject to imperatives and therefore distinct from Humean agency. But it is not necessarily subject to the categorical imperative and hence is distinct from fully spontaneous (transcendentally free) moral agency. A conception thus emerges of an agent with limited spontaneity, subject to hypothetical but not categorical imperatives. A doubt may be raised, however, as to whether Kant's view can accommodate this conception of limited practical spontaneity. Reflection on Kant's notion of a hypothetical imperative suggests that the idea of limited spontaneity is in danger of either collapsing into the Humean picture or else turning out to be equivalent to the conception of full spontaneity appropriate to moral agency. There is thus reason to suppose that, for Kant, we would not be bound by imperatives at all if we were not bound by the categorical imperative.     

Pleasure and Aversion: Challenging the Conventional Dichotomy

Philosophy and its descendents in the behavioral sciences have traditionally divided incentives into those that are sought and those that are avoided. Positive incentives are held to be both attractive and memorable because of the direct effects of pleasure. Negative incentives are held to be unattractive but still memorable (the problem of pain) because they force unpleasant emotions on an individual by an unmotivated process, either a hardwired response (unconditioned response) or one substituted by association (conditioned response). Negative incentives are divided into those that are always avoided and those that are avoided only by higher mental processes—archetypically the passions, which are also thought of as hardwired or conditioned. Newer dichotomies within the negative have been proposed, hinging on whether a negative incentive is nevertheless sought (“wanted but not liked”) or on an incentive's being negative only because it is confining (the product of “rule worship”). The newer dichotomies have lacked motivational explanations, and there is reason to question conditioning in the motivational mechanism for the older ones.

Both experimental findings and the examination of common experience indicate that even the most aversive experiences, such as pain and panic, do not prevail in reflex fashion, but because of an urge to attend to them. The well-established hyperbolic curve in which prospective rewards are discounted implies a mechanism for such an urge, as well as for the “lower” incentives in the other dichotomies. The properties of these lower incentives are predicted by particular durations of temporary preferences on a continuum that stretches from fractions of a second to years.     

Right‐wing authoritarianism and social dominance orientation differentially predict biased evaluations of media reports

This study tested the dual‐process motivational (DPM) model, which posits that right‐wing authoritarianism (RWA) and social dominance orientation (SDO) differentially predict attitudes toward socially threatening or subordinate groups, respectively. Participants read articles on same‐sex relationships and affirmative action and evaluated the article content and the biases of the article authors. The article conclusions (i.e., pro‐ or anti‐same‐sex relationships and affirmative action) were varied between subjects. As expected, only RWA predicted evaluations of the same‐sex relationships articles and authors, whereas only SDO predicted evaluations of the affirmative action articles and authors. These results extend applications of the dual‐process model by demonstrating that RWA and SDO differentially predict evaluations of political information that pertains to socially threatening or subordinate groups, respectively.     

The role of self‐determination in the relationship between social support and physical activity intentions

Using the hierarchical model of intrinsic and extrinsic motivation (HMIEM) and self‐determination theory as theoretical frameworks, the purpose of the present study was to assess the role of motivation‐related variables in the relationship between perceptions of social support and intentions to be physically active. Undergraduate students completed surveys assessing perceptions of social support, psychological needs satisfaction, self‐determination, and future exercise intentions. Model fit with the data was examined and was considered acceptable, indicating that social support was positively related to the satisfaction of psychological needs, which, in turn, was related positively to self‐determination and then to physical activity intentions.
