Language Outcome After Perinatal Stroke: Does Side Matter?

The goal of this study was to examine structured language skills in children with perinatal strokes. Participants were 28 school-age children with early focal brain lesions (17 with left hemisphere [LH] damage, 11 with right hemisphere [RH] damage), and 57 controls. A standardized test of language (Clinical Evaluation of Language Fundamentals–Revised) was administered. Receptive, Expressive, and Total Language scores, as well as subtest scores, were analyzed. Control participants scored within the normal range, whereas the LH and RH groups scored significantly more poorly than did controls. There were no differences between the LH and RH groups on any of the language scores, and all scores were below the 14th percentile. Within the lesion group as a whole, scores were not related to lesion laterality, site, or severity. Results also were not accounted for by socioeconomic status or IQ. However, children who experienced seizures demonstrated significantly poorer performance than did children who did not experience seizures. Damage to either the LH or RH early in development adversely affects later language abilities, particularly on tasks with structured and complex linguistic demands. Although lesion side has little effect, the presence or absence of seizures is a major contributor to language outcome.     

Concurrent validity of the wide range assessment of visual motor abilities in typically developing children ages 4 to 11 years

Pediatric clinicians working with school-age children use the Wide Range Assessment of Visual Motor Abilities (WRAVMA) as a method for evaluating visual perception and motor skills in children despite limited information on concurrent validity. Whether it may be substituted for the Beery-Buktenica Developmental Test of Visual-Motor Integration (VMI) and has suitable estimates of concurrent validity were examined with a convenience sample of 91 typically developing children ages 4 to 11 years. No systematic concurrent validity between the WRAVMA and the VMI emerged. Only two subtests of the WRAVMA (Matching with Visual Perception, and Pegboard with Motor Coordination) gave scores statistically significantly correlated with those on the VMI, and these correlations were weak, accounting for very small amounts of the shared variance. As such, they have low clinical relevance. These findings do not provide evidence of concurrent validity to support the use of WRAVMA as an alternative method for the VMI for assessing children's visual perception and motor skills.     

Visible homonyms are ambiguous, subliminal homonyms are not: a close look at priming

Homonyms, i.e. ambiguous words like ‘score’, have different meanings in different contexts. Previous research indicates that all potential meanings of a homonym are first accessed in parallel before one of the meanings is selected in a competitive race. If these processes are automatic, these processes of selection should even be observed when homonyms are shown subliminally. This study measured the time course of subliminal and supraliminal priming by homonyms with a frequent (dominant) and a rare (subordinate) meaning in a neutral context, using a lexical decision task. In the subliminal condition, priming across prime-target asynchronies ranging from 100 ms to 1.5 s indicated that the dominant meaning of homonyms was facilitated and the subordinate meaning was inhibited. This indicates that selection of meaning was much faster with subliminal presentation than with supraliminal presentation. Awareness of a prime might decelerate an otherwise rapid selection process.     

Which Aspects of a Semistructured Interview,Besides Cognitive Ability Tests,Contribute Incrementally to Predicting the Training Success of Air Traffic Controller Trainees?

This study examined whether a semistructured interview is valid in predicting training performance in theoretical and simulation examinations and overall training success; which aspects of the interview show incremental validity over cognitive ability tests; and whether additional variables enhance the prediction from the interview. The sample involved data from 337 trainees of the German Air Navigation Service Provider selected by the German Aerospace Center and 657 (interview) and 6,885 (cognitive ability) candidates being the corresponding reference samples. Findings indicate incremental validity of the interview over the cognitive ability tests. Additional variables contributed only to the prediction of theoretical examination performance. Attention, general motivation, and social competence predicted the criteria best, particularly the theoretical examination performance and overall training success.     

Proactive climate in a post-reorganization setting: When staff compensate managers' weakness

This study explored the effects of proactive climate on performance in a post-reorganization setting. We hypothesized that proactive climate should have both a direct effect on unit performance and should—in the sense of the “substitutes for leadership” approach—enhance the effect of managers' entrepreneurial attributes (e.g., personal initiative) on unit performance. Hypotheses were tested using data from organizational units, called “centres” (n?=?35), of four recently reorganized public transport organizations. Managers provided ratings of centre performance, and centre members assessed their centre's climate. Proactive climate was positively related with performance. Moderated regression analyses revealed significant interaction effects between proactive climate and some centre manager variables; however, the interaction pattern indicated that proactive climate compensated for a low degree of entrepreneurial attributes.
