Positive Life Events as a Moderator of Stress‐Related Depressive Symptoms

This study examines the relationships among positive life events, negative life events, and depressive symptoms in a sample of college students. Consistent with predictions, the results of a hierarchical multiple regression indicated a significant main effect for negative life events in predicting depressive symptoms such that increases in negative life events were associated with increases in depressive symptoms. There was also significant interaction between positive and negative life events such that the depressive effects of higher levels of negative life events seem to be reduced for subjects who had also experienced higher levels of positive life events.

Differential effects of safety in extinction of anxious responding to a CO2 challenge in patients with panic disorder

Safety-relevant parameters are hypothesized to be important to the maintenance of pathological anxiety. The authors examined the effects of safety information and safety cues on anxious responding to a repeated 35% CO2 challenge in 31 patients with panic disorder. Patients were randomly assigned to one of three conditions: (a) safety information, (b) safety information plus a safety cue, or (c) no safety information. In the safety information group, patients received accurate information regarding the benign effects of the CO2 challenge. In the combined group, patients also received a safety cue that is salient for many patients with panic disorder (i.e., access to an anxiolytic pill during the challenge). The experimental manipulations did not differentially affect anxious responding following an initial challenge. However, after access to the anxiolytic was removed and the challenge procedure was repeated, those in the safety information alone condition showed lower subjective anxiety compared to those in the combined safety information/safety cue group. Findings suggest that safety information facilitates extinction of anxiety but only in the absence of safety cues.     

Effects of training, prompting, and self-monitoring on staff behavior in a classroom for students with disabilities

This study extended the limited research on the utility of tactile prompts and examined the effects of a treatment package on implementation of a token economy by instructional assistants in a classroom for students with disabilities. During baseline, we measured how accurately the assistants implemented a classroom token economy based on the routine training they had received through the school system. Baseline was followed by brief in-service training, which resulted in no improvement of token-economy implementation for recently hired instructional assistants. A treatment package of prompting and self-monitoring with accuracy feedback was then introduced as a multiple baseline design across behaviors. The treatment package was successfully faded to a more manageable self-monitoring intervention. Results showed visually significant improvements for all participants during observation sessions.     

Visuo-tactile links in covert exogenous spatial attention remap across changes in unseen hand posture

We investigated the effect of unseen hand posture on cross-modal, visuo-tactile links in covert spatial attention. In Experiment 1, a spatially nonpredictive visual cue was presented to the left or right hemifield shortly before a tactile target on either hand. To examine the spatial coordinates of any cross-modal cuing, the unseen hands were either uncrossed or crossed so that the left hand lay to the right and vice versa. Tactile up/down (i.e., index finger/thumb) judgments were better on the same side of external space as the visual cue, for both crossed and uncrossed postures. Thus, which hand was advantaged by a visual cue in a particular hemifield reversed across the different unseen postures. In Experiment 2, nonpredictive tactile cues now preceded visual targets. Up/down judgments for the latter were better on the same side of external space as the tactile cue, again for both postures. These results demonstrate cross-modal links between vision and touch in exogenous covert spatial attention that remap across changes in unseen hand posture, suggesting a modulatory role for proprioception.     

Five dangers of materialism

Amidst the boon of medical, scientific, and technological progress, materialism has gained increasing explanatory power in deciphering the enigma of mind. But with the proliferation and acceptance of cognitive science, psychic reality has been largely reduced to a physical ontology. In this article, the author explores the ground, scope, and limits to the materialist framework and shows that although biological-neurochemical physiology is a necessary condition for mental functioning, it is far from a sufficient condition to adequately explain the human being. This situation becomes especially significant when one examines the issues of selfhood, freedom, personal autonomy, and the phenomenal quality of the lived experience.     

A computerized test of speed of language comprehension unconfounded by literacy

A computerized version of the Silly Sentences task developed for use with children is found to be equivalent to the pencil‐and‐paper version from the SCOLP test with UK undergraduates, and is usable by a sample of young UK children. Because the sentences are presented aloud instead of being written, the computerized test is not affected by literacy skills. Translated into Kiswahili, the task was used in Tanzanian schools, despite the absence of an electricity supply and a very different cultural background. The decision latencies had a test–retest reliability of 0.69 over 5 months, and were independent of age and baseline decision speed. The task appears appropriate for longitudinal studies, including those in developing countries. Given its simplicity and the correlations with the original SCOLP version of the task, it may also be useful in studies on literate adults. Copyright © 2001 John Wiley & Sons, Ltd.     

The Effects of Charismatic Leadership on Followers' Self-Concept Accessibility

Shamir, House, and Arthur (1993) suggested that the effects of charismatic leadership on followers' motivation are mediated by the increased salience of collective identities in followers' self-concepts. This study empirically examines the effects of leadership messages on followers' self-concept accessibilities. Charismatic and integrative (combined charismatic and individualized consideration) leadership increased the accessibility of followers' collective self-concepts. Individualized consideration increased the accessibility of followers' private self-concepts. These results support the propositions of the self-concept-based theory of charismatic leadership. Charismatic and integrative leadership messages from a leader resulted in higher follower collective self-concept accessibilities than did routinized messages. This finding underscores the importance of a charismatic leader, even when charismatic messages have become routinized.     

Altruism and egoism: prosocial motivations for helping depend on relationship context

Findings from the current study suggest that the link between helping and empathic concern—a hypothesized motivator of altruistic behavior—may be more pronounced in the context of kinship relationships than among strangers. Participants expressed their willingness to help a kin‐member or stranger in specific need situations. Putative mediators of helping (empathic concern, general negative affect, perceptions of oneness) were measured. Empathic concern appeared to partially mediate effects of relationship context on willingness to help. Moreover, while controlling for egoistic motivators (negative affect, oneness), empathic concern was linked to participants' willingness to help a kin‐member but not a stranger. Findings suggest that factors motivating prosocial action in close relationships may be different from those that motivate helping among strangers. Copyright © 2006 John Wiley & Sons, Ltd.     

Power, risk, and the status quo: does power promote riskier or more conservative decision making?

Two experiments suggest that the experience of power can interact with a person's level of power motivation to produce effects on risky decision making. In Study 1, assignment to a position of power increased risk taking among participants with low levels of power motivation but reduced risk taking among participants with high levels of power motivation. In Study 2, participants high in power motivation again made more conservative decisions, but only under circumstances in which the dominance hierarchy was unstable and there was potential for losing their power. When power was irrevocable and participants' choices had no bearing on their ability to retain power, both high and low power-motivated participants responded by making riskier decisions. Findings suggest that although power may generally lead to riskier decisions, power may lead to more conservative decisions among power-motivated individuals, especially when the status quo is perceived to be in jeopardy.
