The cognitive profile and multiple-deficit hypothesis in Chinese developmental dyslexia

The present study was conducted to examine the cognitive profile and multiple-deficit hypothesis in Chinese developmental dyslexia. Thirty Chinese dyslexic children in Hong Kong were compared with 30 average readers of the same chronological age (CA controls) and 30 average readers of the same reading level (RL controls) in a number of rapid naming, visual, phonological, and orthographic tasks. Chinese dyslexic children performed significantly worse than the CA controls but similarly to the RL controls on most of the cognitive tasks. The rapid naming deficit was found to be the most dominant type of cognitive deficit in Chinese dyslexic children. Over half of the dyslexic children exhibited deficits in 3 or more cognitive areas, and there was a significant association between the number of cognitive deficits and the degree of reading and spelling impairment. The present findings support the multiple-deficit hypothesis in Chinese developmental dyslexia.     

Regional variation in the inversion effect for faces: differential effects for feature shape, feature configuration, and external contour

Faces are perceived via an orientation-dependent expert mechanism. We previously showed that inversion impaired perception of the spatial relations of features more in the lower face than in the (more salient) upper face, suggests a failure to rapidly process this type of structural data from the entire face. In this study we wished to determine if this interaction between inversion and regional salience, which we consider a marker for efficient whole-face processing, was specific to second-order (coordinate) spatial relations or also affected other types of structural information in faces. We used an oddity paradigm to test the ability of seventeen subjects to discriminate changes in feature size, feature spatial relations, and external contour in both the upper and lower face. We also tested fourteen subjects on perception of two different types of spatial relations: second-order changes that create plausible alternative faces, and illegal spatial changes that transgress normal rules of facial geometry. In both experiments we examined for asymmetries between upper-face and lower-face perceptual accuracy with brief stimulus presentations. While all structural changes were less easily discerned in inverted faces, only changes to spatial relations showed a marked asymmetry between the upper and lower face, with far worse performance in the mouth region. Furthermore, this asymmetry was found only for second-order spatial relations and not illegal spatial changes. These results suggest that the orientation-dependent face mechanism has a rapid whole-face processing capacity specific to the internal second-order (coordinate) spatial relations of facial features.     

Intermittent explosive disorder and other psychiatric comorbidity among court-referred and self-referred aggressive drivers

We assessed possible Axis I and Axis II disorders in two groups of aggressive drivers (n=20, court-referred; n=10, self-referred) and 30 non-aggressive driver controls, using the SCID and SCID-II. Aggressive drivers were more likely than controls to be positive for any Axis I and Axis II disorders. They were also more likely to meet the criteria for Intermittent Explosive Disorder (IED), current or past alcohol or substance abuse or dependence and Antisocial PD and Borderline PD. The self-referred aggressive drivers were more likely than court-referred aggressive drivers to meet the criteria for a current or past Anxiety Disorder. Re-analysis of aggressive driver data on the basis of presence or absence of IED revealed differences only in Axis II disorders: those with IED were more likely to meet the criteria for any Axis II disorder and Antisocial PD.     

Academic self-disclosure in adolescence

Adolescents' dialogues with friends and classmates about their academic performance constitute a central arena of self-disclosure for developing teenagers. Yet researchers have generally limited the range of their study of academic self-disclosure to gifted students. This study brings together the literature on self-disclosure, academic achievement, and adolescent development to elucidate the overlapping elements at play in adolescents' everyday decisions to talk about their academic performance. With an ethnically diverse sample of San Francisco Bay Area ("Silicon Valley") 10th and 12th graders, the authors developed a 12-scenario instrument specifying both interpersonal context (attraction/friendship) and relative-intelligence relationship (more, less, or equally smart), querying degrees of academic self-disclosure associated with these contexts. The results indicated that self-disclosure was highly (positively) influenced by the achievement level of both the discloser and listener, modestly influenced by friendship versus romantic interest, and influenced in anticipated directions by gender and age.     

Unwrapping the organizational entry process: disentangling multiple antecedents and their pathways to adjustment

This 4-wave longitudinal study of newcomers in 7 organizations examined preentry knowledge, proactive personality, and socialization influences as antecedents of both proximal (task mastery, role clarity, work group integration, and political knowledge) and distal (organizational commitment, work withdrawal, and turnover) indicators of newcomer adjustment. Results suggest that preentry knowledge, proactive personality, and socialization influences from the organization, supervisors, and coworkers are independently related to proximal adjustment outcomes, consistent with a theoretical framework highlighting distinct dimensions of organizational and work task adjustment. The proximal adjustment outcomes partially mediated most of the relationships between the antecedents of adjustment and organizational commitment, work withdrawal, and turnover.     

A controlled evaluation of cognitive behavioural therapy for posttraumatic stress in motor vehicle accident survivors

Seventy-eight motor vehicle accident survivors with chronic (greater than 6 months) PTSD, or severe sub-syndromal PTSD, completed a randomized controlled comparison of cognitive behavioral therapy (CBT), supportive psychotherapy (SUPPORT), or a Wait List control condition with two detailed assessments. Scores on the CAPS showed significantly greater improvement for those in CBT in comparison to the Wait List and to the SUPPORT conditions. The SUPPORT condition in turn was superior (p=0.012) to the Wait List. Categorical diagnostic data showed the same results. An analysis of CAPS scores including drop-outs (n=98) also showed CBT to be superior to Wait List and to SUPPORT with a trend for SUPPORT to be superior to Wait List. The CBT condition led to significantly greater reductions in co-morbid major depression and GAD than the other two conditions. Results held up well at a 3-month follow-up on the two active treatment conditions.
