Schizotypy,cognitive performance,and genetic risk for schizophrenia in a non-clinical population

Schizophrenia risk alleles are expected to mediate effects on cognitive task performance, and aspects of personality including schizotypy, in nonclinical populations. We investigated how 32 of the best-validated schizophrenia risk alleles, singly and as summed genetic risk, were related to measures of schizotypal personality and measures of two aspects of cognitive performance, verbal skills (vocabulary) and visual-spatial skills (mental rotation), in healthy individuals. Summed genetic risk score was not associated with levels of total schizotypy or its three main subscales. Similarly, genotypic variation at none of the individual risk loci was related to cognitive performance measures, after correction for multiple tests. Higher overall genetic risk score was, however, associated with lower performance on the mental rotation test in males, with a broad set of loci contributing to this effect. These results imply that there is a lack of linear, genetically-based continuity connecting schizotypal cognition with the expression of schizophrenia itself, and indicate that, for males, higher genetic risk of schizophrenia exerts negative effects on visual-spatial skills, as measured by mental rotation.     

Emotion understanding,pictorial representations of friendship and reciprocity in school-aged children

This study examined the relationship between emotional understanding, friendship representation and reciprocity in school-aged children. Two hundred and fifty-one Caucasian 6-year-old children (111 males and 140 females) took part in the study. The Test of Emotion Comprehension (TEC) and the Pictorial Assessment of Interpersonal Relationships (PAIR) were used. Children having a reciprocal friendship and children having a unilateral friendship with a child named as their “best friend” were compared on the emotional understanding task and on their pictorial representations of friendship. Multilevel analyses indicated that friendship status effects were not influenced by classroom-level differences. Results showed that children with reciprocal friendships drew themselves as more similar to and more cohesive with their best friends, and they showed better understanding of emotions, than children having a unilateral friendship. Finally, the implications of these findings for theoretical and empirical research development on friendship are discussed.     

Self-Concepts and Psychological Well-Being Assessed By Beck Youth Inventory Among Pupils with Reading Difficulties

This study investigated the self-image and psychological well-being in 67 children and adolescents age 10–16 years with severe reading difficulties and/or dyslexia. The participants were assessed with Beck Youth Inventory regarding symptoms of depression, anxiety, and negative self-image. The results showed that the participants do not depict negative self-image and showed few symptoms of depression or anxiety at group level in comparison to a norm group. These results could be seen as contradictory to previous research. A questionnaire regarding self-efficacy was also distributed and showed that the participants had low self-knowledge about their reading impairments. The results were interpreted as a possible increase in knowledge among teachers and subsequent change in pedagogical strategies. In addition, technological advances may have improved the academic situation for dyslexic children. This study was a partial study in a larger project that aimed to evaluate the efficiency of assistive technologies for dyslexic children.     

Male and Female Voices in Commercials: Analysis of Effectiveness, Adequacy for the Product, Attention and Recall

In radio advertising, there is a strong tendency to employ male voices more often than female voices in the belief that male voices sound more convincing. As a result, a gender stereotype is established which would appear to be upheld more by tradition than actual advertising effectiveness. This experimental study analyses the influence of gender on the effectiveness of the voice in terms of adequacy to the product, the ability to attract listeners’ attention and the degree to which voice gender contributes to recall. The objective is to ascertain whether or not the patent infra-use of the female voice is justified. To this end, a gender-balanced sample of 372 students of journalism from Spain was employed. The findings show that when a question is asked about an alleged association with a pre-existing vocal stereotype the answer is consistent with the gender of the voice and the type of product, though this does not occur when the aspects are unrelated, such as voice effectiveness, attention or recall. Accordingly, the supremacy of the male voice over the female voice in radio advertising and the repeated association between voices and types of products is more based on tradition than on alleged advertising effectiveness.     

What Counts as Science? Families’ Perceptions of Science in a Natural History Museum

ABSTRACT

Natural history museums open their doors to millions of family visitors each year and are considered to have a valuable role to play in engaging these families with science. Yet little is known about whether or in what way families perceive such institutions to be connected with science. The current study set out to explore such perceptions via interviews with family visitors to a large natural history museum. Analyses reflected that families’ perceptions of the museum and of their own engagement with science were intertwined with their definitions and impressions of science. For these families, perceptions of the museum as fun, interesting, and educational at times counteracted impressions of it as a science-y institution. Moreover, some families also did not consider natural history to count as science, which further contributed to a reluctance to categorize the museum as science-y. Although such perceptions may challenge how natural history museums would like to portray themselves, they also represent an opportunity to broaden visitors’ definitions and images of science.     

Parents Think Their Sons Are Brighter Than Their Daughters: Sex Differences in Parental Self-Estimations and Estimations of Their Children's Multiple Intelligences

In this study, 156 participants, predominantly White British adults (M age = 44.3 years) rated themselves on overall IQ and on H. Gardner's (1983) 7 intelligence subtypes. Parents (n = 120) also estimated the intelligence of their children. Men's self-estimates were significantly higher than women's (110.15 vs. 104.84). Participants thought their verbal, mathematical, and spatial intelligence scores were the best indicators of their own overall intelligence. Parents estimated that their sons had significantly higher IQs than their daughters (115.21 vs. 107.49). Self-estimates and estimates of children's multiple intelligences were higher for men and sons, significantly so for logical-mathematical and spatial intelligence. Parents rated 2nd-born daughters as having significantly higher verbal and musical intelligence than their male counterparts. Higher parental IQ self-estimates corresponded with higher IQ estimates for children. Results for 1st-born children were clearest and showed the most significant differences. The findings are interpreted in terms of sociocultural and familial influences and the possibility of actual sex differences in particular abilities.     

An Item Analysis of the Adjustment Questionnaire

This study examined the relationship of dogmatism, attitude extremity, and the tendency to displace perceptually a neutral communication to a position more discrepant from the subject's own than it objectively holds. Results indicate that dogmatism was not predictive of displacement tendency, but that extremity and intensity were both significantly related to displacement. It was also found that dogmatism was not correlated with having a conservative attitude on the issues studied. The results were consistent across four different attitude issues.     

Comparison of Methods for Collecting and Modeling Dissimilarity Data: Applications to Complex Sound Stimuli

Sorting procedures are frequently adopted as an alternative to dissimilarity ratings to measure the dissimilarity of large sets of stimuli in a comparatively short time. However, systematic empirical research on the consequences of this experiment-design choice is lacking. We carried out a behavioral experiment to assess the extent to which sorting procedures compare to dissimilarity ratings in terms of efficiency, reliability, and accuracy, and the extent to which data from different data-collection methods are redundant and are better fit by different distance models. Participants estimated the dissimilarity of either semantically charged environmental sounds or semantically neutral synthetic sounds. We considered free and hierarchical sorting and derived indications concerning the properties of constrained and truncated hierarchical sorting methods from hierarchical sorting data. Results show that the higher efficiency of sorting methods comes at a considerable cost in terms of data reliability and accuracy. This loss appears to be minimized with truncated hierarchical sorting methods that start from a relatively low number of groups of stimuli. Finally, variations in data-collection method differentially affect the fit of various distance models at the group-average and individual levels. On the basis of these results, we suggest adopting sorting as an alternative to dissimilarity-rating methods only when strictly necessary. We also suggest analyzing the raw behavioral dissimilarities, and avoiding modeling them with one single distance model.     

The development of an evidence-based treatment: Regulation-Focused Psychotherapy for Children with externalising behaviours (RFP-C)

There is a critical need for the development, evaluation and implementation of evidence-based psychodynamic treatments for children and adolescents. Currently, there are no empirically supported, manualised psychodynamic treatments for children and adolescents with disruptive behaviour problems. The field of manualised psychodynamic treatments with measurable equivalence or superiority to other established forms of psychotherapy is in its nascent stage. This paper details a novel, manualised, time-limited psychodynamic treatment approach for children who manifest disruptive behaviours and emotional dysregulation. Regulation-Focused Psychotherapy for Children (RFP-C) conceptualises children’s disruptive and acting out behaviours as expressions of maladaptive emotion regulation. Externalising symptoms are conceptualised as attempts to defend against painful emotions and thus protect the child from disturbing feelings such as sadness, shame and guilt. This paper provides the theoretical basis for the treatment approach and through the use of a clinical example demonstrates the systematic application of RFP-C in a single case.
