Attentional biases in geometric form perception

This paper reports the operation of robust attentional bias to the top and right during perception of small, single geometric forms. Same/different judgements of successively presented standard and comparison forms are faster when local differences are located at top and right rather than in other regions of the forms. The bias persists when form size is reduced to approximately one degree of visual angle, and it is unaffected by saccadic eye movements and by instructions to attend to other reliably differentiating regions of the forms. Results lend support in various degrees to two of the possible explanations of the bias: (1) a static, skewed distribution of attentional resources around eye fixation; and (2) biased, covert scanning that commences invariably at the top and right of stim ulus forms. Origins of the bias in terms of possible left-hemispheric capacity for constructing representations of visual stimuli from parts, as well as in terms of reading experience and prevailing optic flow during locomotion through space are considered. Recent investigations of conditions under which the bias can be maintained or reduced are mentioned.     

Regret and Responsibility Resolved? Evaluating Ordóñez and Connolly's (2000) Conclusions

T. Connolly, L. D. Ordo;aan;atez, and R. Coughlan (1997, Organizational Behavior and Human Decision Processes, 70, 73-85) argued, on the basis of 5 experiments, that regret need not be related to a sense of responsibility for the regretted outcome. We (M. Zeelenberg, W. W. van Dijk, & A. S. R. Manstead, 1998, Organizational Behavior and Human Decision Processes, 74, 254-272) showed in 2 experiments that this conclusion was premature, because it was based on an indirect measure of regret (i.e., overall happiness with the decision outcome). When regret was directly measured, the predicted effects of responsibility were found. L. D. Ordo;aan;atez and T. Connolly (2000, Organizational Behavior and Human Decision Processes, 81, 132-142) replicated our findings in 2 experiments. Based on their findings they arrived at 4 conclusions. In this rejoinder we first discuss Ordó?ez and Connolly's new studies and we then discuss the validity of their 4 conclusions. Copyright 2000 Academic Press.     

A group treatment program for bulimia nervosa

Seventeen female patients diagnosed as exhibiting bulimia nervosa participated in a shortterm group treatment program. A combination of exposure with response prevention, life skills training, and psychodynamic group interaction was provided. Results in pretest vs. posttest scores on a battery of tests demonstrated improved control over eating behavior and lowered anxiety and depression.     

Child and familial pathways to academic achievement and behavioral adjustment: a prospective six-year study of children with and without ADHD

This longitudinal study examined familial and child predictors of academic achievement and behavioral adjustment. Participants included 115 children with ADHD and 59 normative comparisons. Data analyses spanned three assessment waves from elementary- through secondary-school grades. We evaluated the degree to which child and familial factors present during middle school mediated relationships between childhood ADHD, subsequent academic achievement, and behavioral adjustment during high school. We found that emotional and behavioral well-being of ADHD children during middle school mediated relations between childhood ADHD and adverse academic and behavioral outcomes during high school. In addition, familial factors in middle school years predicted the behavioral adjustment of children in both the ADHD and non-ADHD groups. Academic achievement during high school was strongly associated with previous achievement levels. Our results provide support for tailoring preventive interventions to the unique needs of children with ADHD and their parents at various stages of adolescent development.     

Clinical issues in the assessment of adolescent alcohol and other drug use

Clinicians working with adolescents are routinely faced with the issue that alcohol and other drug (AOD) involvement may be part of the clinical picture either as a primary problem or a contributing factor to other problems or disorders. Fortunately, assessment research in this area has produced several behaviorally oriented and psychometrically sound tools from which to choose for problem identification, referral and treatment of youth suspected of AOD abuse. The aim of this paper is to provide an overview of several issues related to the clinical utility of such assessment tools.     

Neighborhood & Family Effects on Learning Motivation among Urban African American Middle School Youth

Motivational theorists in psychology have moved away from individual-based approaches to socio-cognitive and socio-ecological models to explain student engagement and motivation for learning. Such approaches consider, for example, the influence of family and neighborhood environments as important constructs in youth behavior. In this study, links between neighborhood condition (e.g. external appearance of the blocks nearest to the respondents’ home), family dysfunction, and motivation for learning are investigated. Data were obtained from two hundred and sixteen (216) urban African American middle school children enrolled in a substance use prevention intervention. Analytic models show associations between poor neighborhood condition, and both family dysfunction and lower learning motivation, and poor neighborhood condition and lower learning motivation. Family dysfunction was also found to mediate the effect of neighborhood condition on motivated learning. Neighborhood and family characteristics are important determinants of urban schoolchildren’s motivation for learning.     

Is horror a necessary component of flooding (implosion)?

Experimental results indicate that presentation of horrifying scenes is not necessary to obtain a favorable outcome in the treatment of phobias by flooding. Prolonged exposure to the feared object, even under relatively pleasant conditions is sufficient. Subjects were college students who rated highly fearful of rats. They were randomly assigned to one of three experimental groups and to a no treatment-control group. Treatment groups differed along the dimension of harshness of scene presentation. Control group subjects received no treatment but were assessed repeatedly as were experimental subjects. All experimental subjects showed improvement irrespective of treatment received-after treatment they were all willing to come closer to a live rat and experienced less anxiety at the closest point. However, subjects exposed to horrid scenes were judged by an independent evaluator as less likely to avoid fearful situations. The discussion centers on the discrepancy between rater's evaluation and other measures, implications of the results for treatment, and on the generalizability of findings to a patient population.     

Eye-movement data: Cumulative fixation time and cluster analysis

This paper describes procedures for the visual presentation and cluster analysis of eye-movement data. Methods for two- and three-dimensional representation of cumulative fixation time (CFT) and ways of enhancing the peaks in CFT distributions are outlined and illustrated by reference to examples from eye-movement studies of cognitive processes. CFT distributions may also be partitioned using thek means clustering technique (MacQueen, 1967), and applications of variants of this technique to eye-movement data are discussed. Cluster analyses such ask means require the user to make initial estimates of the number and value of the means. One classification procedure (Wallace & Boulton, 1968a, 1968b), based on information theory, avoids these initial assumptions. This procedure is applied to a CFT distribution and has its solution compared with that ofk means for the same distribution. Finally, programs that implement these procedures on Macintosh computers are listed and offered on floppy disk.     

The importance of subjective norms for people who care what others think of them

Using the framework of the Theory of Planned Behaviour (TPB), this study examined whether the extent to which people are concerned with others’ approval of them moderates the subjective norms–intentions relationship in the context of exercise. The participants were 325 undergraduate students who completed a questionnaire assessing the TPB constructs (subjective norms, attitudes, perceived behavioural control, intentions) and the Brief Fear of Negative Evaluation Scale. The results of hierarchical regression analyses indicated that subjective norms were a significant predictor of intentions to exercise only for people highly concerned with receiving disapproval from others (i.e., high fear of negative evaluation) and not for people low on this trait.
