Nature and nurture: Williams syndrome across cultures

This study is concerned with ways in which children with Williams syndrome (WS), a rare neurodevelopmental disorder arising from a hemizygous deletion in chromosome band 7q11.23 including the gene for elastin (ELN) and approximately 20 surrounding genes, are affected by social mores of vastly differing cultures: the United States and Japan. WS presents a compelling model for the investigation because its genetic phenotype is well defined and results in an uneven cognitive profile as well as a social phenotype typical of the syndrome including overt over-friendliness toward strangers. While a number of research groups have been studying the cognitive strengths and weaknesses of individuals with WS in various countries, there have not been studies to date that explore the social phenotype in WS across different cultures. This study examines the ways in which social behavior in WS, stemming from specific genetic underpinnings, might be mediated by cultural expectations. We conducted a cross-cultural study using an instrument that measures aspects of sociability commonly found among people with WS. Quantitative analyses revealed a significant effect of diagnostic category in that in both countries, children with WS were rated as significantly higher in global sociability and more likely to approach strangers than were their normal counterparts. There was also an effect of culture, in that regardless of category, WS and normal children in Japan were rated lower than their counterparts in the US. We suggest that the excessively social phenotype of children with Williams syndrome, although markedly present across cultures, appears to vary in its intensity by culture. This is an intriguing illustration of interactions between nature and nurture.     

Post-September 11th Perspectives on Religion, Spirituality, and Philosophy in the Personal and Professional Lives of Selected REBT Cognoscenti

The purpose of this article was for selected Rational Emotive Behavior Therapy (REBT) cognoscenti to examine the impact of the events of September 11th, 2001, on their beliefs about religion, spirituality, and their personal philosophy—including the role of evil in the universe and the implications of these issues on their use of REBT. The degree of consistency of the author’s views with classical REBT theory and philosophy was examined. The authors are current or former members of the Albert Ellis Institute’s International Training Standards and Policy Review Committee, of which Albert Ellis, REBT’s founder, is also a member.

Spirituality/Religiosity (SpR), Leisure-Time Physical Activity,and Sedentary Behaviour in Students at a Catholic University

Some studies have found an association between spirituality and/or religiosity (SpR) and cardiovascular health, for reasons which remain unclear. This study explores whether SpR is linked to physical activity whilst young, which in turn is linked to long-term cardiovascular health. Students at a Catholic University in Australia completed a survey combining the SpREUK-P SF 17 SpR questionnaire with elements of the long-form 7-day recall International Physical Activity Questionnaire. Respondents who scored highly in the unconventional spiritual practices components of SpREUK-P engaged in moderate intensity physical activity more frequently. This finding may have implications for health promotion.     

Item type,occlusion, and gender differences in mental rotation

Two experiments were conducted to examine the role of item type in mental rotation. In each experiment, participants completed two computerized mental rotation tasks, one with blocks as stimuli and one with human figures as stimuli. The tasks were formatted either as a multiple-choice psychometric test (Experiment 1) or as a same–different type task (Experiment 2). Aside from the expected replication of a decreased effect of occlusion on women's accuracy when processing human figures compared to block figures, it was hypothesized that response times would increase when processing the complex but familiar human figures, compared to the simple but unfamiliar block figures. In Experiment 1, the results relevant to occlusion were replicated. However, the presence of a speed–accuracy trade-off suggested that participants processed human figures faster but less accurately than block figures. In Experiment 2, both men and women performed faster and more accurately when processing occluded human figures than when processing nonoccluded human figures. The effect of item type, its potential link to embodied cognition, and the role of strategy selection on gender differences in mental rotation are discussed.     

A hierarchical LSI-11 system for real-time control,interevent time storage,and data analysis

A general-purpose laboratory computer system using two Digital Equipment Corporation LSI-11 s in a master-slave relationship is described. The implementation includes hardware to install an LSI-11 as a slave parallel processor, to provide special-purpose functions such as a real-time clock and a 4K FIFO interprocessor buffer, and to establish a bus that permits the use of inexpensive interfaces to experimental equipment. The slave processor generates a complete log of each input or output event. Data in the form of the time of each event are continuously passed through the FIFO to a foreground task in the main LSI-11, which in turn stores the raw data on a hard disk. A macro library allows the easy development of experimentcontrol programs. A library of FORTRAN routines provides a pointer-based conditional and iterative search facility that can sift out any specifiable event or set of events from the data records for subsequent analysis. This computer system provides the user with an inexpensive facility to run up to 32 simultaneous experiments with complete data logging in foreground while program development, analysis, and word processing are concurrently being done in background.     

Detectionless processing with semantic activation? A footnote to Greenwald,Klinger, and Liu (1989)

Recently published research has suggested that, in a pattern masking task, semantic activation caused by the target may continue to exist even though subjects cannot detect the target. The experiments are reassessed as an exceptional case of the more general rule that subjects are able to use residual semantic activation to actually detect targets. Furthermore, residual graphic information is far less effective at supporting near-chance target detections.     

The socialization of sex-differentiated skills and academic performance: A mediational model

Using a multifactorial model, sex differences in academic performance were examined in a sample of 347 elementary school children. As expected, girls' academic performance averaged higher than boys'. Path analysis confirmed initial hypotheses that girls' advantage is partially due to their characteristic of greater responsiveness to social cues and compliance with adult direction. This advantage was partially offset in this model by boys' greater visual-spatial skill, which also was a predictor of academic success. Access to stereotypic masculine toys and activities at home was, for both sexes, a predictor of children's visual-spatial ability. As expected, socioeconomic variables, including mothers' occupation and fathers' level of education, also influenced the environmental, social, and cognitive factors predicting academic success. These results indicate that boys' and girls' differential development of specific cognitive and social skills may play an important role in establishing sex differences in academic performance.     

Factor structure of the Condoms Barriers Scale with a sample of men at high risk for HIV

This study assesses the psychometric properties of the Condom Barriers Scale (CBS), an instrument originally designed to measure women's perceptions and attitudes regarding male condom use, with a sample of men at high risk for human immunodeficiency virus (HIV). Participants include 590 male patients in drug abuse treatment involved in a gender-specific HIV prevention intervention for teaching safer sex skills. Second-order confirmatory factor analysis generally supported the underlying four-factor subscale structure of the CBS. However, exploratory factor analysis revealed a few specific discrepancies in the factor structure between men and women. Internal consistency and test-retest reliability estimates were moderate to high in value. CBS scores correlated with use of condoms for men with high-risk sexual partners, supporting criterion-related validity. Overall, the analysis indicates that the CBS is a potentially valid and reliable instrument and has utility for assessing barriers to condom use with men, but may need some item content modifications to allow appropriate assessment of gender differences and comparisons across studies.
