Valuing Environmental Outcomes: Preferences for Constant or Improving Sequences

Experimental results on individuals' preferences for temporal sequences of environmental outcomes related to air quality and near-shore ocean water quality are compared with preferences for sequences of health and monetary outcomes. Generally, graduate business student participants gave significantly lower ratings to environmental and health sequences (with equal means) that worsened over time, relative to the ratings they gave to sequences that either remained the same or improved over time. This pattern was reversed by the participants when they faced sequences of monetary payments. This preference structure held for both short (5-year) and long (50-year) time horizons, and it was confirmed with choice data. A model proposed by Loewenstein and Prelec for the valuation of sequences of outcomes was applied to the current data set and compared to the traditional discounting model. In all cases, the model that incorporated “Gestalt” features of the sequence (slope and uniformity) performed better than the net present value discounting model at predicting the mean ratings for the sequences in the different domains.     

White Racism and Suboptimal Psychological Functioning Among White Americans: Implications for Counseling and Prejudice Prevention

This study examined the causal relationships between anxiety, racism, and self‐esteem in a sample of White graduate and undergraduate students (N = 169). The results indicated that level of anxiety had a direct effect on anti‐Black attitudes, which, in turn, had a direct effect on self‐esteem. Implications for counseling interventions aimed at preventing prejudice among Whites are discussed. Este estudio examinó las relaciones causales entre la ansiedad, el racismo, y el auto‐estima en un grupo de estudiantes graduados y estudiantes de bachillerato Blancos (N = 169). Los resultados indicaron que el nivel de ansiedad tuvo un efecto directo en las actitudes anti‐Negras, que en torno tuvo un efecto directo en el auto‐estima. Las implicaciones para las intervenciones de consejería dirigidas a prevenir el prejuicio entre los Blancos son discutidas.     

Individual differences in children's understanding of social evaluation concerns

Recent research suggests that children's understanding of self‐presentational behaviour—behaviour designed to shape social evaluation—is a function of both cognitive and motivational variables. Furthermore, the motivational factors involved are likely to reflect individual differences in the salience of concerns about social evaluation. The present research represents a first effort to determine whether measures of such differences are indeed associated with the understanding of self‐presentational behaviour. In a first experiment, a teacher rating measure of self‐monitoring was found to be positively associated with the understanding of self‐presentational motives. In a second experiment, a more narrowly specified self‐report measure of public self‐consciousness was found to have a similar association with the understanding of self‐presentation, with no such association found for private self‐consciousness. These preliminary results make it clear that our formulations of development in social cognition must indeed include a consideration of individual differences in motivational orientations.

Developing Standard Recommendations (Guidelines) for Genetic Counseling Practice: A Process of the National Society of Genetic Counselors

The National Society of Genetic Counselors (NSGC) supports the development of practice recommendations (guidelines) in the field of genetic counseling. This paper reviews the basic components of NSGC genetic counseling practice recommendations as well as the process for formal adoption of such documents, as approved by the Board of Directors of the NSGC.     

Teasing,rejection, and violence: Case studies of the school shootings

Media commentators have suggested that recent school shootings were precipitated by social rejection, but no empirical research has examined this claim. Case studies were conducted of 15 school shootings between 1995 and 2001 to examine the possible role of social rejection in school violence. Acute or chronic rejection—in the form of ostracism, bullying, and/or romantic rejection—was present in all but two of the incidents. In addition, the shooters tended to be characterized by one or more of three other risk factors—an interest in firearms or bombs, a fascination with death or Satanism, or psychological problems involving depression, impulse control, or sadistic tendencies. Implications for understanding and preventing school violence are discussed. Aggr. Behav. 29:202–214, 2003. © 2003 Wiley‐Liss, Inc.     

The Protestant Work Ethic,Expectancy Violations,and Criminal Sentencing1

To test the hypothesis that endorsement of the Protestant work ethic would be related positively to sensitivity to criminal behavior that violated expectations, American college students (N = 159) read scenarios describing a crime committed by a typical or an atypical offender. After answering questions about the crime, they completed Mirels and Garrett's (1971) Protestant Work Ethic (PWE) scale. Extent of punishment was positively related to PWE for atypical criminal behavior. Yet, high PWEs also were more likely to perceive an affluent criminal as experiencing greater remorse for a blue‐collar crime than a white‐collar crime. We relate our results to perceptions of criminal behavior, information‐processing tendencies among individuals endorsing the PWE, and jury selection considerations.     

Further considerations of a general d′ in multidimensional space

Thomas (Psychonom. Bull. Rev. 6 (1999) 224) proposed a generalization of d′,d_g′ for multidimensional distributions and demonstrated that it is not equivalent to Euclidean distance as had been assumed in some previous studies. In this note, it is further shown not to be a metric in the general sense as it fails the triangle inequality. Also, a rigorous proof is offered of the claim (found in Thomas, Psychonom. Bull. Rev. 6 (1999) 224) that in order for the definition of d_g′ to correspond to the quantity that is estimated from data in the traditional way (using hits and false alarms) one must assume a distance classifier (proved in the case of equal covariance matrices). If one assumes optimal responding instead, then the estimated d′ corresponds to (the square root of) Mahalanobis distance. This latter observation clears up an apparent paradox between the fact that d_g′ is not a metric and Ashby and Perrin's (Psychol. Rev. 95 (1988) 124) statement relating the weighted Euclidean scaling model and a signal detection model of similarity that would yield a distance classifier.
