Power Spectral Density Analysis of Lateral Human Standing Sway

A number of investigators have used power spectral density (PSD) analysis to try to identify and quantify various sensory systems which are involved in upright standing. Using PSD analysis, over a frequency range from 0.02-2.5 Hz, the present study examined two trials of lateral sway in each of 80 men. The results showed that little change occurred in PSD values between the first and second trials. Exponential curves were fit to the averaged trials data of each subject. The values of the parameter estimates obtained from the curve-fitting were regressed on the values of various direct, and derived anthropometric variables to try to explain the variance of the parameter estimates in terms of the anthropometrics. The subject’s center of gravity location accounted for no more than 15.8% of the parameter variance, whereas the remaining anthropometrics explained even less. The overall averaged data suggest that three functions (related to visual, vestibular, and proprioceptive processes) may underlie the sway pattern over this frequency range. PSD curves of individuals with a history of high-level athletic activity clearly differed from those of sedentary subjects.     

Psychometric Characteristics of the Multidimensional Scale of Perceived Social Support

The initial study describing the development of the Multidimensional Scale of Perceived Social Support (MSPSS) indicated that it was a psychometrically sound instrument (Zimet, Dahlem, Zimet, & FarIey, 1988). The current study attempted to extend the initial findings by demonstrating the internal reliability, factorial validity, and subscale validity of the MSPSS using three different subject groups: (a) 265 pregnant women, (b) 74 adolescents living in Europe with their families, and (c) 55 pediatric residents. The MSPSS was found to have good internal reliability across subject groups. In addition, strong factorial validity was demonstrated, confirming the three-subscale structure of the MSPSS: Family, Friends, and Significant Other. Finally, strong support was also found for the validity of the Family and Significant Other subscales.     

Uptake of Breast Screening is Influenced by Current Religion and Religion of Upbringing

Research has shown that individuals with a current religious affiliation are more likely to use preventive health services. The aim of this study was to determine whether breast screening uptake in Northern Ireland is higher amongst women with a current affiliation to an organised religion and, for those with no current affiliation, to examine whether their religion of upbringing is associated with uptake of breast screening. The Northern Ireland Longitudinal Study (NILS) was used to link Census and national breast screening data for 37,211 women invited for routine breast screening between 2001 and 2004. Current religious affiliation, religion of upbringing and other demographic and socio-economic characteristics were as defined on the Census form. Multivariate logistic regression was used to determine the relationship between religion affiliation and attendance. Uptake of breast screening is about 25% lower for those without a current religious affiliation. There are modest differences between Catholics and Protestants, with the latter about 11% more likely to attend for screening. For those with no current religion, the religion of upbringing appears to positively influence attendance rates. These differences remain after adjustment for all of the socio-demographic and socio-economic factors that have been shown to influence uptake rates of breast screening in the UK to date. Record linkage is an efficient way to examine equity across demographic characteristics that are not routinely available. The lower uptake amongst those with no religious affiliation may mean that screening services may find it difficult to maintain or improve uptake rate in an increasingly secularised society.     

Interview anxiety across the sexes: Support for the sex-linked anxiety coping theory

The sex-linked anxiety coping theory states that females’ anxiety levels may be less detrimental to their selection test performance because they have more available coping resources and engage in more constructive coping strategies prior to and during selection tests. This research project sought to investigate whether gender moderates the link between interview anxiety and interview performance. Co-op students (N = 125) participated in a mock interview as part of a course requirement. The results indicated that gender moderated the relation between self-rated interview anxiety and interview performance. Males were no more anxious than were females, but experienced significantly greater impairments to performance in the job interview as a result of interview anxiety. Of interest, interviewer-rated interview anxiety did not interact with gender to predict interview performance, which supports preliminary research evidence that perceptions and the experience of interview anxiety are not necessarily congruent.     

Teoría multifactorial-sistemática—exposición sucinta—

RESUMEN

Los autores esbozan su Teoría Multifactorial Sistemática, que presenta una concepción general de la estructura, dinámica y desarrollo de las diferencias individuales en la personalidad integradora. Se analiza la estructura y dinámica de la individualidad desde el marco conceptual del procesamiento de la información, en el cual la personalidad -o el sistema psicológico total- viene a ser concebida como un compuesto jerárquico organizado de seis sistemas en interacción: sensorial, motor, cognitivo, afectivo, estilos y valores. Para ello comienzan con algunos comentarios acerca del modelo factorial y el de sistemas, describiendo seguidamente su concepción actual de “estructura”, “dinámicas” y “desarrollo” de la individualidad. A continuación se ocupan del significado de la interacción herencia-ambiente y persona-situación, y finalizan discutiendo problemas empíricos y teóricos no resueltos y las implicaciones de su teoría.     

Reading and Social Imagination: What Relationally Oriented Reading Instruction Can Do for Children

Twenty-two second and third grade children experiencing difficulties with social relationships and reading comprehension participated in small group Relationally Oriented Reading Instruction for eight weeks. Developmental and literacy assessments done before and after the reading intervention showed statistically significant improvements in the understanding of text and in social imagination. Analysis of writing samples resulted in a typology of relationally oriented response. Together these data provide initial evidence linking the understanding of texts to the development of other relational capacities like social imagination, and indicate that purposeful use of picture books within relationally oriented reading instruction may enhance this development.     

Assessing Personality in the Employment Interview: The Impact of Training on Rater Accuracy

We developed a training protocol to enhance interviewers' knowledge of personality-related cues and, in so doing, improve the accuracy of their personality judgments. Participants (N = 164) watched 3 videotaped mock employment interviews and judged the personality of those interviewees. The trained group was more accurate than the control group for some, but not all, of the rated traits. It was predicted that training would increase participants' dispositional intelligence (knowledge of personality) scores. This hypothesis was not supported, suggesting that trait cue knowledge and dispositional intelligence may function independently in the improvement of rating accuracy. These findings contribute to further articulation of the process underlying accurate personality inferences.     

Examining the role of parental self-regulation in family physical activity: A mixed-methods approach

Physical activity (PA) is essential for good health. However, parents risk becoming less active because of the demands of parenting. This has consequences for children as parents are role models. The present study used a mixed-methods approach to explore parental self-regulation associated with PA. Data were collected from 36 parents with preschool-aged children. They were interviewed about their PA and their family’s PA. Parents also completed PA and self-regulation questionnaires and wore an accelerometer for five days. Qualitative data were examined using an inductive approach to thematic analysis. It showed that parents felt that they had limited time for personal PA. Mothers’ self-regulation was driven by an ethic of care and subjective norms, whereas fathers’ self-regulation was driven by beliefs about the importance of autonomy. Nevertheless, both parents saw caring for their children as the main priority. Quantitative data were examined using multiple regression analyses. Results showed that different self-regulatory behaviours predicted the PA of mothers and fathers. Which predictors were significant depended on the type of activity and how it was measured. The findings warrant longitudinal research that would enable the effect of family dynamics on self-regulation associated with PA to be assessed.
