Am I ‘Chinese’ or ‘Scottish’? children’s perceptions of the adaptive nature of Chinese Scottish children’s dual identities

Chinese Scottish children (children who are born and live in Scotland with Chinese parents) face challenges in establishing their identity. However, there is lack of research that investigates ethnic minority Chinese children’s identity and associated feelings about the dual social context in which they live. The study introduced a social identity vignettes task to examine Chinese Scottish and White Scottish children’s perceptions of Chinese ethnic identity and Scottish national identity of a Scottish born Chinese character within two contrasting socio-cultural contexts (Scottish vs. Chinese). This study examines whether children’s ethnic and national identity and feelings of positivity are adaptive and sensitive to social context. In addition it explored age-related changes in perceptions of ethnic and national identification in the vignettes. The sample comprised of 161 children (8, 11, and 14 years). The results found Chinese Scottish children and White Scottish children’s judgments of the characters’ ethnic identity changed with the cultural context. Both groups of children had a similar perception of vignette characters’ feeling of positivity. Both Chinese and White Scottish children judged that the character would feel more positive about him/herself in the Chinese context. There was no main effect of age.     

False recall in the Deese-Roediger-McDermott paradigm: The roles of gist and associative strength

Theories of false memories, particularly in the Deese-Roediger-McDermott (DRM) paradigm, focus on word association strength and gist. Backward associative strength (BAS) is a strong predictor of false recall in this paradigm. However, other than being defined as a measure of association between studied list words and falsely recalled nonpresented critical words, there is little understanding of this variable. In Experiment 1, we used a knowledge-type taxonomy to classify the semantic relations in DRM stimuli. These knowledge types predicted false-recall probability, as well as BAS itself, with the most important being situation features, synonyms, and taxonomic relations. In three subsequent experiments, we demonstrated that lists composed solely of situation features can elicit a gist and produce false memories, particularly when monitoring processes are made more difficult. Our results identify the semantic factors that underlie BAS and suggest how considering semantic relations leads to a better understanding of gist formation.     

The reliability and validity of the panic disorder self-report: a new diagnostic screening measure of panic disorder

This study examined the Panic Disorder Self-Report (PDSR), a new self-report diagnostic measure of panic disorder based on the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association, 1994). PDSR diagnoses were compared with structured interview diagnoses of individuals with generalized anxiety disorder, social phobia, and panic disorder and nonanxious controls. Receiver operating characteristic analyses revealed that the PDSR showed 100% specificity and 89% sensitivity. The PDSR also demonstrated retest reliability, convergent and discriminant validity, and kappa agreement of .93 with a structured interview. Finally, the PDSR demonstrated clinical validity. Students who were identified as having panic disorder using the PDSR did not have significantly different scores on the Panic Disorder Severity Scale--Self-Report form (P. R. Houck, D. A. Speigel, M. K. Shear, & P. Rucci, 2002) than a panic disordered community sample. However, both groups had significantly higher scores than students identified as not meeting criteria for panic disorder.     

Text comprehension in middle aged adults: is there anything wrong?

Two experiments tested text comprehension skills in adults varying in age from 20 to 69 years. A coherence judgment task (n = 39), in which the pragmatic connection of two sentences had to be evaluated, did not yield any age effects. Both error rates and reaction times were largely independent of age. In a word recognition paradigm (n = 60), testing the strength of different text representation levels, there was a gradual, linear decrease in performance with age, accompanied by a similarly gradual increase in processing times. The results confirm that aging affects comprehension under high memory demands, but spares the conceptual, situation-based levels. Most importantly, it was shown that these changes become apparent during middle age already. Implications for education and neuropsychology are discussed.     

The neurobiology of adaptive learning in reading: A contrast of different training conditions

fMRI was used to investigate the separate influences of orthographic, phonological, and semantic processing on the ability to learn new words and the cortical circuitry recruited to subsequently read those words. In a behavioral session, subjects acquired familiarity for three sets of pseudowords, attending to orthographic, phonological, or (learned) semantic features. Transfer effects were measured in an event-related fMRI session as the subjects named trained pseudowords, untrained pseudowords, and real words. Behaviorally, phonological and semantic training resulted in better learning than did orthographic training. Neurobiologically, orthographic training did not modulate activation in the main reading regions. Phonological and semantic training yielded equivalent behavioral facilitation but distinct functional activation patterns, suggesting that the learning resulting from these two training conditions was driven by different underlying processes. The findings indicate that the putative ventral visual word form area is sensitive to the phonological structure of words, with phonologically analytic processing contributing to the specialization of this region.     

The scaling of postural adjustments during bimanual load-lifting in traumatic brain-injured adults

Previous postural studies of traumatic brain injury (TBI) patients have been limited to identifying deficits in static and quasi-dynamic postural control tasks such as weight shifting. In this study, we examined whether or not patients with TBI are able to scale adequately their postural adjustments during the performance of the dynamic task of bimanual load-lifting. An age matched group of healthy adults served as controls. We used the Tetrax posturography system that calculates a stability score (ST) based on fluctuations in vertical ground reaction forces, normalized for body weight. During quiet standing, the ST scores of the TBI group were significantly higher than the control group. Forward weight shift and percentage change in the vertical ground reaction forces (lift postural adjustment (LPA) and post-lift postural adjustment (PLPA) scores) linearly increased with increasing load weight in both healthy and TBI subjects. Group differences were found in the magnitude of forward weight shift but not in the relative increase of the LPA and PLPA scores during the lifting and post-lifting phases respectively. The forward weight shift of the TBI group was lower-than-normal and asymmetrical--there was significantly less forward weight shift on the more affected than on the less affected limb. In addition, a significant amplitude coupling was found between the scaling of the weight shift of the heel and forefoot of each limb. However, no coupling was found between the weight shift amplitudes of homologous parts of both limbs in the TBI group. The results showed that scaling based on prior experience was preserved in the TBI group, though some TBI subjects demonstrated absent scaling in either the more affected or less affected heel or forefoot. The differences between the normal and TBI groups in postural adjustments are not necessarily a sign of pathology; rather they may represent a deliberate choice of the central nervous system to counteract predictable disturbances.     

Parental Meta-Emotion Philosophy in Families with Conduct-Problem Children: Links with Peer Relations

We addressed the question of whether mothers of conduct-problem (CP) children differ from mothers of non-CP children in their awareness and coaching of emotion, and also examined whether mother's awareness and coaching of emotion is associated with better peer relations in CP children. Meta-emotion philosophy, assessed through audio taped interviews, and preschool children's peer relations, observed in same-sex dyadic interaction with a close friend, were investigated in families with CP and non-CP children. Results indicated that mothers of CP children were less aware of their own emotions and less coaching of their children's emotions than mothers of non-CP children. Moderation analyses revealed that children's level of aggression moderated the relationship between mother's meta-emotion and children's peer play. For both aggressive and nonaggressive children, higher levels of mother awareness and coaching of emotion was associated with more positive and less negative peer play, although effects were stronger for families with nonaggressive children. These data suggest that both aggressive and nonaggressive children can benefit when parents are more aware and coaching of emotion. Implications for the development of an intervention program aimed at improving parental awareness and coaching of emotion is discussed.
