Relations between self-serving cognitive distortions and overt vs. covert antisocial behavior in adolescents

The present study addressed the relations between cognitive distortions (inaccurate thoughts, attitudes, or beliefs) and antisocial behavior that is either overt/confrontational (e.g., fighting) or covert/nonconfrontational (e.g., stealing). A controlled analysis of 52 male delinquents and a comparison sample of 51 high school students aged 14–18 years found the delinquents to be higher in both cognitive distortions and self-reported antisocial behavior. Furthermore, cognitive distortion related specifically to overt and covert antisocial behavior in both samples. In particular, cognitive distortion having overt antisocial behavior as its referent (e.g., “People need to be roughed up once in a while”) evidenced a significant path to overt but not covert antisocial behavior. Conversely, covert-referential cognitive distortion (e.g, “If someone is careless enough to lose a wallet, they deserve to have it stolen”) evidenced a significant path to covert but not overt antisocial behavior. The theoretical and treatment implications of the findings are discussed. Aggr. Behav. 24:335–346, 1998. © 1998 Wiley-Liss, Inc.     

Exercise of Human Agency Through Collective Efficacy

Social cognitive theory adopts an agentic perspective in which individuals are producers of experiences and shapers of events. Among the mechanisms of human agency, none is more focal or pervading than the belief of personal efficacy. This core belief is the foundation of human agency. Unless people believe that they can produce desired effects and forestall undesired ones by their actions, they have little incentive to act. The growing interdependence of human functioning is placing a premium on the exercise of collective agency through shared beliefs in the power to produce effects by collective action. The present article analyzes the nature of perceived collective efficacy and its centrality in how people live their lives. Perceived collective efficacy fosters groups' motivational commitment to their missions, resilience to adversity, and performance accomplishments.     

Stream segregation of narrow-band noise bursts

Normally hearing adults heard rapid alternations of a pair of band-limited noise bursts that had flat spectra (in terms of equal-loudness weighting of components) and sharp band edges. The bursts differed in center frequency (CF), but were matched on overall intensity, on bandwidth (BW) on a logfrequency scale, and (roughly) on pitch strength. Listeners judged the ease with which the sequence could be held together perceptually in a single auditory stream (vs. forming separate high and low streams). Involuntary segregation was examined as a function of the following measures of frequency separation of the alternating noise bands: (1) the closest band edges, (2) the most remote band edges, (3) the CFs of the bands on a logarithmic scale, and (4) the BWs. Segregation was best predicted from the separation of the two CFs on a log-frequency scale (very strong effect). Increasing the BWs of the two alternating bursts (the same size, in log frequency, for both bands) also led to greater segregation (very weak effect).     

The generic-viewpoint assumption and illusory contours

Visual images are ambiguous. Any image, or collection of images, is consistent with an infinite number of possible scenes in the world. Yet we are generally unaware of this ambiguity. During ordinary perception we are generally aware of only one, or perhaps a few of these possibilities. Human vision evidently exploits certain constraints--assumptions about the world and images formed of it--in order to generate its perceptions. One constraint that has been widely studied by researchers in human and machine vision is the generic-viewpoint assumption. We show that this assumption can help to explain the widely discussed fact that outlines of blobs are ineffective inducers of illusory contours. We also present a number of novel effects and report an experiment suggesting that the generic-viewpoint assumption strongly influences illusory-contour perception.     

The community alcohol use scale: A scale for use in prevention programs

The Community Alcohol Use Scale (CAUS) was developed as a continuous, reliable, valid, and acceptable measure for primary prevention studies. Items were written following a comprehensive review of the literature on alcohol dependence and alcoholism. Based upon the responses of 315 respondents to the 100-item initial version of the scale, the 45-item CAUS was developed. The CAUS was then cross-validated on a local sample (n = 274) and a provincial sample (n = 745). Estimates of internal consistency were .91, .96, and .94, respectively, for the initial and cross-validation samples. Correlations of .48 and .69 were obtained between the CAUS and the Michigan Alcohol Screening Test for the initial and local cross-validation samples. In the provincial cross-validation sample a correlation of .62 was obtained between the CAUS and the Usual Weekly Alcohol Index. Preliminary cutting scores were developed to identify those at risk for alcoholism, and alcoholics. The CAUS has potential use as an evaluative and predictive instrument in a variety of primary prevention programs.
