Preliminary validation of a Chinese version of the State-Trait Anger Expression Inventory-2

The increased globalization of psychology and related fields necessitates the availability of psychometric instruments in a number of languages, countries and cultures. Unfortunately, research on anger and aggression in Chinese populations has suffered from a lack of valid and reliable measurement instruments. Therefore, the State-Trait Anger Expression Inventory-2 (STAXI-2) was translated into Chinese (Chinese STAXI-2). Two samples of Hong Kong Chinese ( N  = 489 and N  = 775) completed the Chinese STAXI-2. Participants in the second sample also completed measures of anger rumination and aggression. Confirmatory factor analysis (CFA) of responses from the first sample resulted in the loss of nine items from the 57 original items due to misspecification. A second CFA, using responses from the second sample, supported the construct validity of the modified scale. Moderate correlations were observed with measures of aggression and anger rumination, and significant differences were found between males and females on three anger expression subscales (Anger Expression-In, Anger Control-Out, and Anger Control-In). The preliminary evidence suggests that the abbreviated inventory may be a useful measure of state and trait anger, and anger expression in some Chinese populations.     

孤独症生命早期脑过度生长现象及启示

孤独症神经结构研究中近来一个重要的发现是,孤独症生命早期存在脑过度生长的现象。进一步的探查表明,孤独症个体脑的过度生长主要由脑白质的过度生长造成,并且脑的过度生长又主要体现于那些较晚成熟的高级脑区。这一研究成果有助于孤独症儿童的早期发现和诊断,也提示孤独症并不是由单一的局部神经缺陷造成,其存在着广泛分布式的神经发展障碍

Timed performance weaknesses on computerized tasks in pediatric brain tumor survivors: A comparison with sibling controls

With more children surviving a brain tumor, insight into the late effects of the disease and treatment is of high importance. This study focused on profiling the neurocognitive functions that might be affected after treatment for a pediatric brain tumor, using a broad battery of computerized tests. Predictors that may influence neurocognitive functioning were also investigated. A total of 82 pediatric brain tumor survivors (PBTSs) aged 8–18 years (M = 13.85, SD = 3.15, 49% males) with parent-reported neurocognitive complaints were compared to a control group of 43 siblings (age M = 14.27, SD = 2.44, 40% males) using linear mixed models. Neurocognitive performance was assessed using measures of attention, processing speed, memory, executive functioning, visuomotor integration (VMI), and intelligence. Tumor type, treatment, tumor location, hydrocephalus, gender, age at diagnosis, and time since diagnosis were entered into regression analyzes as predictors for neurocognitive functioning. The PBTSs showed slower processing speeds and lower intelligence (range effect sizes .71–.82, p < .001), as well as deficits in executive attention, short-term memory, executive functioning, and VMI (range effect sizes .40–.57, p < .05). Older age at assessment was associated with better neurocognitive functioning (B = .450, p < .001) and younger age at diagnosis was associated with lower intelligence (B = .328, p < .05). Medical risk factors, e.g., hydrocephalus, did not show an association with neurocognitive functioning. Late effects in PBTSs include a broad range of neurocognitive deficits. The results suggest that even PBTSs that were traditionally viewed as low risk for neurocognitive problems (e.g., surgery only, no hydrocephalus) may suffer from decreased neurocognitive functioning.     

Working memory outcomes following traumatic brain injury in children: A systematic review with meta-analysis

The aim of this review is to systematically examine the literature concerning multicomponent working memory (WM)—comprising a central executive (CE), two storage components (phonological loop, PL and visuo-spatial sketchpad, VSSP), and episodic buffer (EB)—in pediatric traumatic brain injury (TBI). Electronic searches were conducted of MEDLINE, PsychINFO and EMBASE up to October 2014 with the inclusion criteria of children and adolescents with TBI, and quantitative methods to assess at least one component of WM. Meta-analytic procedures calculated pooled effect sizes for WM outcomes. Of the studies examined, 27 met the inclusion criteria. Children with TBI exhibited deficits in the CE and PL, but not in the VSSP, and no study could be found which examined the EB. Qualitative analysis found that greater TBI severity was associated with poorer CE functioning in five out of nine studies. Differences in patterns of brain activation were evident in four out of five fMRI studies that examined WM in TBI children and controls. Deficits in CE were associated with poorer mathematical skills in the only study that examined relations between WM and academic deficits. Notwithstanding the heterogeneity of the studies reviewed, TBI places children at risk of WM deficits. Moreover, this meta-analysis suggests that various components of WM have differential vulnerability to pediatric TBI, with significant deficits found in the CE and PL, but not in the VSSP (although the VSSP has rarely been examined to date). Future studies should be theoretically driven, employ tasks assessing all components of the WM model and examine the functional ramifications (including academic outcomes) of WM deficits in this population.     

Parental ratings of daily behavior and child cognitive test performance after pediatric mild traumatic brain injury

This study aimed to evaluate the degree to which the Behavior Rating Inventory of Executive Function (BRIEF) and Child Behavior Checklist (CBCL) measure overlapping vs. distinct constructs in pediatric patients with mild traumatic brain injury (TBI), and to examine the demographic and injury correlates of such constructs as well as those of cognitive test performance. A total of 100 parents completed the BRIEF and the CBCL within 1 to 12 months after the injury of their child. Groups were contrasted based on the presence vs. absence of impairment on, respectively, the BRIEF and the CBCL. Exploratory maximum likelihood factor analysis was used to evaluate latent constructs. Correlates of the various factor scores were evaluated through regression analysis and contrasted with those of a test of verbal learning and memory.The results revealed that the BRIEF and the CBCL disagree about the presence vs. absence of impairment in about one quarter of cases. A prior history of attention deficit/hyperactivity disorder (ADHD) was associated with an increased likelihood of impairment on both the BRIEF and the CBCL, whereas prior outpatient psychiatric treatment was associated with the increased likelihood of selective impairment on the CBCL. Latent constructs manifested themselves along cognitive regulation, emotional adjustment and behavioral regulation factors. Whereas premorbid characteristics were the exclusive correlates of these factors, performance on a test of verbal learning and memory was negatively affected by intracranial lesions on neuroimaging.It is concluded that the BRIEF and the CBCL offer complementary and non-redundant information about daily functioning after pediatric mild TBI. The correlates of cognitive test performance and parental behavior ratings after such injuries are different and reflect a divergence between premorbid and injury-related influences.     

The neural basis of mirror symmetry detection: a review

The human visual system is extremely sensitive to the presence of bilateral (mirror) symmetry. In this review, I summarise the results of recent work investigating the neural basis of mirror symmetry detection, focusing in particular on brain stimulation evidence. Overall, available findings converge in pointing to the lateral occipital (LO) complex, especially in the right hemisphere, as a key region causally involved in symmetry detection. Interestingly, they also suggest that another region in the right extrastriate visual cortex, the occipital face area (OFA), is causally implied in symmetry detection, posing an interesting connection at the neural level between visual cortex responses to faces and to symmetry. Finally, this review also considers evidence on haptic symmetry detection in sighted and early blind individuals that points to LO as a multi-modal symmetry-sensitive region, and suggests that symmetry is a salient perceptual feature mediated by LO even when any visual experience is missing.     

简单算术对汉语特定句型的结构启动

结构启动是指个体在产生或理解一个结构时,倾向于重复使用或仿照刚刚加工过的结构。与句法启动不同的是,结构启动除了以句子,也可以以其它抽象结构作为启动项。Scheepers et al. (2011) 首次以具有结构偏向性的抽象算式作为启动项,证实了高附着和低附着的简单算式对英语母语者产出高附着和低附着关系从句具有结构启动效应。在此基础上,本研究引用数学算式作为启动项,以汉语特定句型结构NP1+有+NP2+恨+(AP)为切入点,分别选取汉语成人和儿童受试,检验简单算式对汉语母语者产出或理解特定句型的结构启动效应。本研究发现：1）算式结构对汉语特定句型的产出具有结构启动效应。2）算式结构对汉语歧义句的解读具有结构启动效应。3）儿童和成人在产出和理解的启动实验中具有不同结构启动效应,且儿童的结构启动效应比成人的结构启动效应更强。4）算式结构和语言句式在认知上具有共享的结构表征。
