The skill of recognizing musical structures

In three experiments, musicians and nonmusicians were compared in their ability to discriminate musical chords. Pairs of chords sharing all notes in common or having different notes were played in succession. Some pairs of chords differed in timbre independent of their musical structures because they were played on different instruments. Musicians outperformed nonmusicians only in recognizing the same chord played on different instruments. Both groups could discriminate between instrument timbres, although musicians did slightly better than nonmusicians. In contrast, with chord structures not conforming to the rules of tonal harmony, musicians and nonmusicians performed equally poorly in recognizing identical chords played on different instruments. Signal detection analysis showed that musicians and nonmusicians set similar criteria for these judgments. Musicians' superiority reflects greater sensitivity to familiar diatonic chords. These results are taken as evidence that musicians develop perceptual and cognitive skills specific to the lawful musical structures encountered in their culture's music. Nonmusicians who lack this knowledge based their judgments on the acoustical properties of the chords.     

Adolescents' occupational and educational goals: A test of reciprocal relations

During adolescence, young people's future aspirations and expectations begin to crystallize, especially in the domains of education and occupation. Much of the research in this area has emphasized development within a particular domain (e.g., education) and relations between aspirations and expectations across domains remain largely unexplored, resulting in a lack of information on how goals develop in tandem and affect each other. It is also unclear whether these developmental processes differ by gender and socioeconomic status. We tested reciprocal effects between occupational and educational goals using a longitudinal sample of 636 adolescents (52% boys). Results from dynamic systems models indicated change in occupational and educational goals across high school. For all youth, occupational aspirations predicted change in occupational expectations. Educational expectations predicted change in occupational aspirations for youth in high but not low parent education groups, and occupational expectations predicted change in educational expectations for girls but not boys.     

The REBT Competency Scale for Clinical and Research Applications

This paper presents the REBT Competency Scale which can be used in the evaluation of adherence to an REBT treatment model in clinical and research applications. The scale has been developed to map closely onto the REBT treatment protocol developed by Dryden et al. (A primer on rational emotive behaviour therapy, Research Press, Champaign, 2003). Based on this treatment protocol 21 core steps (tasks) were identified for effective REBT practice. Each step is operationally defined, the rater is reminded of how the step relates to REBT theory and practice and scoring criteria are established that enable a rating of the therapists performance of the task. The potential uses for and application of the scale in clinical and research settings are considered.     

Colour, face, and visuospatial imagery abilities in low-vision individuals with visual field deficits

This study investigates to what extent visual perception integrity is necessary for visual mental imagery. Sixteen low-vision participants with severe peripheral visual field loss, 16 with severe central field loss, 6 left brain-damaged patients with right homonymous hemianopia, 6 right brain-damaged patients with left homonymous hemianopia, and 16 normally sighted controls performed perceptual and imagery tasks using colours, faces, and spatial relationships. Results showed that (a) the perceptual and mental image>ry disorders vary according to the type of visual field loss, (b) hemianopics had no more difficulties imagining spatial stimuli in their contralesional hemispace than in their ipsilesional one, and (c) the only hemianopic participant to have perceptual and mental imagery impairments suffered from attentional deficits. Results suggest that (a) visual memory is not definitively established, but rather needs perceptual practice to be maintained, and (b) that visual mental imagery may involve some of the attentional-exploratory mechanisms that are employed in visual behaviour.     

Effects of disclosure of traumatic events on illness behavior among psychiatric prison inmates

To assess the health effects of writing about traumatic events in a clinical population, 98 psychiatric prison inmates were randomly assigned to 1 of 3 conditions in which they were asked to write about their deepest thoughts and feelings surrounding upsetting experiences (trauma writing condition), write about trivial topics (trivial writing control), or go about their daily routine without writing (no-writing control). Both writing groups wrote for 20 min per day for 3 consecutive days. Participants in the trauma condition reported experiencing more physical symptoms subsequent to the intervention relative to those in the other conditions. Despite this, controlling for prewriting infirmary visits, sex offenders in the trauma writing condition decreased their postwriting infirmary visits. These results are congruent with predictions based on stigmatization and inhibition.     

Predictors of opposition to and support for the ordination of women: insights from the LDS Church

Female ordination is an important component of gender equality in Christian religious communities. While prior research has examined societal, institutional, and organisational factors that predict changes in ordination policies in Christian denominations, there is very little research examining individuals’ attitudes regarding the ordination of women. In this research, we use data from two surveys of members of The Church of Jesus Christ of Latter-day Saints (LDS) to examine the factors that predict attitudes towards the ordination of women using two polity-specific measures of support or opposition. Results indicate greater support for the ordination of women when framed in a way that takes into account LDS church governance. While several demographic variables predict attitudes towards ordination, the strongest correlate is perceptions of inequality.
