Significance,structure, and gender differences in life domains of college students

The purpose of this study was to assess the significance and structure of life domains of college students and to explore the patterns of gender differences on different indices of significance. Four hundred fifty-seven college students rated 21 life domains in terms of degree of importance, frequency of involvement, and level of impact. They also responded to a measure of global life satisfaction. Gender differences on significance indices were investigated by means of three types of analyses. First, gender mean ratings on 21 life domains were compared via one-way multivariate analyses of variance. Second, the underlying dimensions of the 21 domains for each gender were compared via exploratory factor analyses. Third, the correlation patterns between perceived positive impact of each life domain and life satisfaction were calculated separately for men and women. Within-group comparisons revealed that men and women shared the same nine most significant domains: education, friends, biological needs, leisure, family, health, couple, esthetics, and physical activities. However, several gender differences were consistently found in the three types of analyses. The results indicated that although traditionally feminine domains are rated as more significant to women than men, traditional masculine domains were rated as equally significant by men and women. Domains considered sex role neutral (e.g., personal planning) were rated as more significant by women than men. In general, women appear to experience greater cognitive, affective, and behavioral aspects of significance in a wider spectrum of activities and as well perceive their general life satisfaction as deriving from a broader range of sources. Results also highlight the importance of assessing the degree of significance of life domains as an initial step in the development of multidimensional self-related constructs.Preparation of this paper was made possible through grants from the Social Sciences and Humanities Research Council of Canada, the Fonds pour la Formation des Chercheurs et l'Aide à la Recherche (FCAR-Québec) and the Université du Québec à Montréal.

A corpus of 714 full-color images of depth-rotated objects

A set of full-color images of objects is described for use in experiments investigating the effects of in-depth rotation on the identification of three-dimensional objects. The corpus contains up to 11 perspective views of 70 nameable objects. We also provide ratings of the “goodness” of each view, based on Thurstonian scaling of subjects’ preferences in a paired-comparison experiment. An exploratory cluster analysis on the scaling solutions indicates that the amount of information available in a given view generally is the major determinant of the goodness of the view. For instance, objects with an elongated front-back axis tend to cluster together, and the front and back views of these objects, which do not reveal the object’s major surfaces and features, are evaluated as the worst views.     

Recognition times of different views of 56 depth-rotated objects: A note concerning Verfaillie and Boutsen (1995)

The present study examines the effect of thegoodness of view on the minimal exposure time required to recognize depth-rotated objects. In a previous study, Verfaillie and Boutsen (1995) derived scales of goodness of view, using a new corpus of images of depth-rotated objects. In the present experiment, a subset of this corpus (five views of 56 objects) is used to determine the recognition exposure time for each view, by increasing exposure time across successive presentations until the object is recognized. The results indicate that, for two thirds of the objects,good views are recognized more frequently and have lower recognition exposure times thanbad views.     

Shape equivalence under perspective and projective transformations

When a planar shape is viewed obliquely, it is deformed by a perspective deformation. If the visual system were to pick up geometrical invariants from such projections, these would necessarily be invariant under the wider class of projective transformations. To what extent can the visual system tell the difference between perspective and nonperspective but still projective deformations of shapes? To investigate this, observers were asked to indicate which of two test patterns most resembled a standard pattern. The test patterns were related to the standard pattern by a perspective or projective transformation, or they were completely unrelated. Performance was slightly better in a matching task with perspective and unrelated test patterns (92.6%) than in a projective-random matching task (88.8%). In a direct comparison, participants had a small preference (58.5%) for the perspectively related patterns over the projectively related ones. Preferences were based on the values of the transformation parameters (slant and shear). Hence, perspective and projective transformations yielded perceptual differences, but they were not treated in a categorically different manner by the human visual system.     

Croyances de contrôle et rendement scolaire chez des élèves francophones du primaire au Québec

Recent research in educational psychology, both in the United States and Europe, suggested that students' control beliefs must be considered to understand interindividual variations in students' personal engagement in learning and academic achievement. The present study was conducted with 780 French-speaking elementary school children from grade four to six. The objectives were to examine: (1) the relation between dimensions of control beliefs, (2) whether there were age-related changes in children's control beliefs, and (3) the relation between control beliefs and academic achievement across school grades. Results showed that the relations between dimensions of control beliefs and children's judgements about their importance in school achievement were stable across school grades. No relation was found between children's judgements about usefulness of specific means and academic achievement, but children's beliefs about their capacity to use these means was a powerful predictor of academic achievement. The discussion focuses on similarities and dissimilarities of these findings with those of studies conducted in the United States and Europe.     

Can career self-directedness be improved through counseling?

We examine the learnability, antecedents and outcomes of career self-directedness using a longitudinal dataset of Flemish career counseling clients. The results show that the career counseling clients improved their career self-directedness during the counseling and that this improvement lasted for at least 6 months. Furthermore, we found career self-directedness to be explained in a significant way by self-awareness and adaptability, two competences identified by Hall [Hall, D. T. (1996). Protean careers in the 21st century. Academy of Management Executive, 10(4), 8-16; Hall, D. T. (2004). The protean career: A quarter-century journey. Journal of Vocational Behavior, 65(1), 1-13] as crucial for steering one’s career. Also, career self-directedness related positively to training participation, job mobility and career satisfaction. The main implications of our findings for the protean career and the career counseling literature are discussed.     

Capturing ruminative exploration: Extending the four-dimensional model of identity formation in late adolescence

Identity exploration has been associated with openness and curiosity but also with anxiety and depression. To explain these mixed findings, the four-dimensional identity formation model [Luyckx, K., Goossens, L., Soenens, B., & Beyers, W. (2006b). Unpacking commitment and exploration: Validation of an integrative model of adolescent identity formation. Journal of Adolescence, 29, 361–378.] was extended using data from two late adolescent samples (total N = 703). A fifth dimension, labeled ruminative (or maladaptive) exploration, was added as a complement to two forms of reflective (or adaptive) exploration already included in the model (i.e., exploration in breadth and exploration in depth). Results indicated that ruminative exploration was positively related to distress and to self-rumination. The two forms of reflective exploration, by contrast, were unrelated to well-being and positively to self-reflection. Ruminative and reflective exploration also helped to distinguish between two types of less adaptive identities (i.e., Ruminative Moratorium and Diffused Diffusion) in a six-cluster solution that also contained adaptive types of identity. Implications for current research on identity formation are discussed.     

The effects of simulated stuttering and prolonged speech on the neural activation patterns of stuttering and nonstuttering adults

Functional magnetic resonance imaging was used to investigate the neural correlates of passive listening, habitual speech and two modified speech patterns (simulated stuttering and prolonged speech) in stuttering and nonstuttering adults. Within-group comparisons revealed increased right hemisphere biased activation of speech-related regions during the simulated stuttered and prolonged speech tasks, relative to the habitual speech task, in the stuttering group. No significant activation differences were observed within the nonstuttering participants during these speech conditions. Between-group comparisons revealed less left superior temporal gyrus activation in stutterers during habitual speech and increased right inferior frontal gyrus activation during simulated stuttering relative to nonstutterers. Stutterers were also found to have increased activation in the left middle and superior temporal gyri and right insula, primary motor cortex and supplementary motor cortex during the passive listening condition relative to nonstutterers. The results provide further evidence for the presence of functional deficiencies underlying auditory processing, motor planning and execution in people who stutter, with these differences being affected by speech manner.
