A constructionist account of emotional disorders

Lindquist et al. present a strong case for a constructionist account of emotion. First, we elaborate on the ramifications that a constructionist account of emotions might have for psychiatric disorders with emotional disturbances as core elements. Second, we reflect on similarities between Lindquist et al.'s model and recent attempts at formulating psychiatric disorders as networks of causally related symptoms.     

Central executive involvement in children's spatial memory

Previous research with adults found that spatial short-term and working memory tasks impose similar demands on executive resources. We administered spatial short-term and working memory tasks to 8- and 11-year-olds in three separate experiments. In Experiments 1 and 2 an executive suppression task (random number generation) was found to impair performances on a short-term memory task (Corsi blocks), a working memory task (letter rotation), and a spatial visualisation task (paper folding). In Experiment 3 an articulatory suppression task only impaired performance on the working memory task. These results suggest that short-term and working memory performances are dependent on executive resources. The degree to which the short-term memory task was dependent on executive resources was expected to be related to the amount of experience children have had with such tasks. Yet we found no significant age-related suppression effects. This was attributed to differences in employment of cognitive strategies by the older children.     

Delinquency in gangs — Selection or socialization?

Thornberry, Krohn, Lizotte, and Chard-Wierschem's (1993) introduced three models to account for why gangs are associated with high levels of delinquency. Existing research using Thornberry et al.'s (1993) models to explain the gang-delinquency association has been inconclusive. This paper seeks to address this gap in research by incorporating Moffitt's (1993) developmental taxonomy of delinquency within Thornberry et al.'s (1993) explanatory models. A few proposals are put forth in this paper: (1) support for Thornberry et al.'s (1993) models depends on developmental stage of the individual, (2) the selection model explains delinquency of life-course-persistent gang members, while social facilitation model explains delinquency of adolescence-limited gang members, and (3) support for the enhancement model is an artifact of assuming a homogenous gang sample.     

Co-occurrence frequency evaluated with large language corpora boosts semantic priming effects

In recent decades, many computational techniques have been developed to analyse the contextual usage of words in large language corpora. The present study examined whether the co-occurrence frequency obtained from large language corpora might boost purely semantic priming effects. Two experiments were conducted: one with conscious semantic priming, the other with subliminal semantic priming. Both experiments contrasted three semantic priming contexts: an unrelated priming context and two related priming contexts with word pairs that are semantically related and that co-occur either frequently or infrequently. In the conscious priming presentation (166-ms stimulus-onset asynchrony, SOA), a semantic priming effect was recorded in both related priming contexts, which was greater with higher co-occurrence frequency. In the subliminal priming presentation (66-ms SOA), no significant priming effect was shown, regardless of the related priming context. These results show that co-occurrence frequency boosts pure semantic priming effects and are discussed with reference to models of semantic network.     

Mimicry and helping behavior: an evaluation of mimicry on explicit helping request

Research found that mimicry behavior led to increased helping behavior toward the mimicker and is associated with higher positive evaluation of the mimicker. Furthermore, studies on helping behavior focused only on implicit helping behavior, whereas no experimental study on explicit helping request was tested. An experiment was carried out in which a female student-confederate mimicked or not mimicked a participant during a discussion about paintings and, after that, solicited the participant for a written feedback about an essay. It was found that mimicry increased compliance to the confederate's request.     

Regional differences in the listener's phonemic inventory affect semantic processing: A mismatch negativity (MMN) study

Using the mismatch negativity (MMN) response, we examined how Standard French and Southern French speakers access the meaning of words ending in /e/ or /ε/ vowels which are contrastive in Standard French but not in Southern French. In Standard French speakers, there was a significant difference in the amplitude of the brain response after the deviant-minus-standard subtraction between the frontocentral (FC) and right lateral (RL) recording sites for the final-/ε/ word but not the final-/e/ word. In contrast, the difference in the amplitude of the brain response between the FC and RL recording sites did not significantly vary as a function of the word’s final vowel in Southern French speakers. Our findings provide evidence that access to lexical meaning in spoken word recognition depends on the speaker’s native regional accent.     

The effects of mothers' past infant-holding preferences on their adult children's face processing lateralisation

Face processing development is negatively affected when infants have not been exposed to faces for some time because of congenital cataract blocking all vision (Le Grand, Mondloch, Maurer, & Brent, 2001). It is not clear, however, whether more subtle differences in face exposure may also have an influence. The present study looked at the effect of the mother's preferred side of holding an infant, on her adult child's face processing lateralisation. Adults with a mother who had a left-arm preference for holding infants were compared with adults with a mother who had a right-arm holding preference. All participants were right-handed and had been exclusively bottle-fed during infancy. The participants were presented with two chimeric faces tests, one involving emotion and the other one gender. The left-arm held individuals showed a normal left-bias on the chimeric face tests, whereas the right-arm held individuals a significantly decreased left-bias. The results might suggest that reduced exposure to high quality emotional information on faces in infancy results in diminished right-hemisphere lateralisation for face processing.     

Correlates of Academic Procrastination and Students’ Grade Goals

This study examined correlates of academic procrastination and students’ grade goals in a sample of 226 undergraduates from Singapore. Findings indicated that self-efficacy for self-regulated learning was significantly and negatively related to procrastination. High self-efficacy for self-regulated learning also predicted students’ expectations of doing well and low self-efficacy for self-regulated learning predicted students’ expectations of not doing well academically. Additionally, help-seeking predicted students’ expectations of doing well academically while academic stress predicted students’ expectations of not doing well academically. Implications for education and educational practice were discussed. This project was partially supported by the Undergraduate Research Experience on Campus (URECA) program from Nanyang Technological University, Singapore.     

Reliability,Validity and Invariance of the Narcissistic Personality Questionnaire for Children-Revised (NPQC-R)

Using confirmatory factor analysis, this study compared the 4-factor 18-item Narcissistic Personality Questionnaire for Children (NPQC) and the 2-factor, 12-item Narcissistic Personality Questionnaire for Children-Revised (NPQC-R). Support was found for the 2-factor structure of the 12-item NPQC-R using two independent adolescent school-based samples (n = 479 and n = 470). The 2-factor NPQC-R model (i.e., Superiority, Exploitativeness) showed a better fit in both adolescent samples than the alternative 4-factor NPQC model. There was strong support for NPQC-R’s invariance across gender and age. The NPQC-R was found to have reasonable internal consistency estimates, test–retest reliability estimates, and adequate convergent and discriminant validity estimates. Collectively, these results support the utility of the NPQC-R as a measure of narcissism in children and adolescents. A copy of the NPQC-R and scoring key can be obtained from Rebecca P. Ang.
