The family career development project in Chinese Canadian families

Based on an action-theoretical conceptualization, this research examined the family career development project in Chinese Canadian families. Six families, each composed of a parent and adolescent, participated in a videotaped conversation to determine a family career development project that was subsequently monitored over a 6-month period and followed up with a second videotaped conversation. The further analysis of these data from a larger data set of 20 Chinese Canadian and European Canadian families resulted in the delineation of several properties of the career development project in Chinese Canadian families, including the importance of the parental agenda, the adolescent’s involvement, parental communication of convincing reasoning, and the adolescent’s withholding and withdrawing response. The findings also indicated that a family career development was central to other higher order projects in the family, including the relationship and cultural projects. The data supported the understanding of project as joint goal-directed action over time and as the basis on which career development influence was organized in these families.     

Hinge versus twist: the effects of 'reference surfaces' and discontinuities on stereoscopic slant perception

Stereoscopic slant perception around a vertical axis (horizontal slant) is often found to be strongly attenuated relative to geometric prediction. Stereo slant is much greater, however, when an adjacent surface, stereoscopically in the frontal plane, is added. This slant enhancement is often attributed to the presence of a 'reference surface' or to a spatial change in the disparity gradient (introducing second and higher derivatives of disparity). Gillam, Chambers, and Russo (1988 Journal of Experimental Psychology: Human Perception and Performance 14 163-175) questioned the role of these factors in that placement of the frontal-plane surface in a direction collinear with the slant axis (twist configuration) sharply reduced latency for perceiving slant whereas placing the same surface in a direction orthogonal to the slant axis (hinge configuration) had little effect. We here confirm these findings for slant magnitude, showing a striking advantage for twist over hinge configurations. We also examined contrast slant measured on the frontal-plane surface in the hinge and twist configurations. Under conditions where test and inducer surfaces have centres at the same depth for twist and hinge, we found that twist configurations produced strong negative slant contrast, while hinge configurations produced significant positive contrast or slant assimilation. We conclude that stereo slant and contrast effects for neighbouring surfaces can only be understood from the patterns and gradients of step disparities present. It is not adequate to consider the second surface merely as a reference slant for the first or as having its effect via a spatial change in the disparity gradient.     

Learning Experiences Contributing to Service-Delivery Competence in Applied Psychologists: Lessons for Sport Psychologists

The purpose of the present study was to compare learning experiences perceived to contribute to service-delivery competence in sport, clinical, and counseling psychologists. Twenty psychologists (11 female, 9 male; 28–70 years of age) participated in semistructured interviews. All participants emphasized the role of client interactions in learning service-delivery processes. In addition, clinical and counseling participants reported personal therapy and supervision as influential experiences. Applied implications for training include (a) regional supervision networks comprising peers and elders, (b) university-based sport psychology clinics, and (c) personal and professional development groups.     

Convergent and discriminative validity of interview and questionnaire measures of personality disorder in mentally disordered offenders: a multitrait-multimethod analysis using confirmatory factor analysis

Measures of personality disorder from the International Personality Disorder Examination, Personality Diagnostic Questionnaire, and Millon Clinical Multiaxial Inventory (MCMI-II) were obtained from detained male mentally disordered offenders (N = 156), and convergent and discriminant validity were examined by confirmatory factor analysis of the multitrait-multimethod matrix. Hierarchical comparisons of models varying in their specification of trait and method variance established the appropriateness of a model supporting both convergence and discrimination across methods, but these were variable across constructs and measures. Convergence was good for avoidant, schizoid, and antisocial disorders, but poor for histrionic, narcissistic, and obsessive-compulsive disorders. Avoidant, schizoid, and schizotypal disorders were not clearly distinguishable from each other. Measurement error attributable to method variance was substantial for all instruments and for most disorders. The commonly alleged superiority of interview over questionnaire methods was not supported, and the MCMI-II demonstrated proportionately more "true" variance. However, assessment methods may be differentially sensitive to different kinds of personality disorder problems.     

An examination of sources of peer-review bias

Peer-review ratings of 1,983 posters submitted for three annual conferences of a professional society were examined for evidence of bias. Hypotheses derived from the literature on the better-than-average effect were tested by analyzing 7,383 sets of ratings. Reviewers who authored posters gave lower average ratings than reviewers who did not author posters. Posters having authorship that included at least one reviewer received higher ratings than those having only nonreviewing authors. Reviewers' experience and professional role were also explored as biasing factors. The ratings were converted into z scores, and differences in reliability and acceptance decisions were examined. Implications for current peer-review practices are discussed.     

Higher-order dimensions of personality disorder: hierarchical structure and relationships with the five-factor model, the interpersonal circle, and psychopathy

Two studies examined the higher-order factor structure of DSM-IV personality disorders using the International Personality Disorder Examination in male forensic psychiatric patients. In Study 1 (N = 168), exploratory factor analysis at the level of individual personality disorder criteria indicated nine primary factors. Exploratory and confirmatory factor analyses of these first-order factors supported a hierarchical structure in which two of three second-order factors covaried to yield a third-order factor. The two resulting superordinate factors were labelled Anxious-Inhibited and Acting Out. In Study 2 (N = 160), we used exploratory and confirmatory factor analyses to test hypotheses of common dimensions underlying these superordinate factors of personality disorder and superordinate factors of the five-factor model of personality, dimensions of the interpersonal circle, and psychopathy. Of three common factors, one combined Anxious-Inhibited disorders, "neurotic introversion," and hostile-submission. The other two factors of Acting Out/ psychopathy and antagonism/hostile-dominance covaried to yield a superordinate factor. Possible substrates underlying two superordinate dimensions common to normal and abnormal personality were identified in the theoretical literature.     

Modal Logic As Dialogical Logic

The title reflects my conviction that, viewed semantically,modal logic is fundamentally dialogical; this conviction is based on the key role played by the notion of bisimulation in modal model theory. But this dialogical conception of modal logic does not seem to apply to modal proof theory, which is notoriously messy. Nonetheless, by making use of ideas which trace back to Arthur Prior (notably the use of nominals, special proposition symbols which name worlds) I will show how to lift the dialogical conception to modal proof theory. I argue that this shift to hybrid logic has consequences for both modal and dialogical logic, and I discuss these in detail.     

Delay discounting as emotional processing: An electrophysiological study

Both theoretical models and functional imaging studies implicate the involvement of emotions within the delay discounting process. However, defining this role has been difficult to establish with neuroimaging techniques given the automaticity of emotional responses. To address this, the current study examined electrophysiological correlates involved in the detection and evaluation of immediate and delayed monetary outcomes. Our results showed that modulation of both early and later ERP components previously associated with affective stimuli processing are sensitive to the signalling of delayed rewards. Together with behavioural reaction times that favoured immediacy, we demonstrated, for the first time, that time delays modify the incentive value of monetary rewards via mechanisms of emotional bias and selective visual attention. Furthermore, our data are consistent with the hypothesis that delayed and thus intangible rewards are perceived less saliently, and rely on emotion as a common currency within decision making. This study provides a new approach to delay discounting and highlights a potential novel route through which delay discounting may be investigated.     

Reading and Phonological Awareness Skills in Children Exposed to Domestic Violence

This study examined whether children exposed to domestic violence perform worse on tests of reading and phonological awareness than children from nonviolent homes. Forty children, ages 6 to 9 years, were divided into control or domestic violence groups based on their mothers' responses on the revised Conflict Tactics Scales (CTS2). The groups were matched on age, gender, nonverbal IQ, and socioeconomic status. The domestic violence group performed worse than the control group on all measures of reading and phonological awareness. Significantly more children in the domestic violence group were identified as having reading difficulties compared to the control group. The results suggest that domestic violence may negatively impact children's reading skills, and appropriate intervention techniques should be developed.
