Parenting styles or practices? Parenting, sympathy, and prosocial behaviors among adolescents

In the present study, the authors examined the relations among parenting styles, parental practices, sympathy, and prosocial behaviors in adolescents. The participants were 233 adolescents (M age = 16.7 years; 69% girls; mostly White) from public high schools in the Midwestern region of the United States who completed measures of prosocial behaviors, parenting styles, parenting practices, and sympathy. Overall, the authors found evidence that parenting practices were significantly associated with adolescents' prosocial behaviors. However, the associations between parenting practices and prosocial behaviors occurred mostly through the indirect relations with sympathy. The relations among parenting practices, sympathy, and prosocial behaviors varied as a function of the specific parenting practice and the specific prosocial behavior. Implications for future research on the study of prosocial development and parenting among adolescents are discussed.     

A window on the normal development of sensitivity to global form in Glass patterns

We studied the development of sensitivity to global form in 6-year-olds, 9-year-olds, and adults (n = 24 in each group) using Glass patterns with varying ratios of paired signal dots to noise dots. The developmental pattern was similar whether the global structure within the Glass patterns was concentric or parallel. Thresholds were equally immature for both types of pattern at 6 years of age (about twice the adult value) but were adult-like at 9 years of age. Together, the results indicate that the cortical structures involved in the processing of global form achieve functional maturity between 6 and 9 years of age. During middle childhood, the mechanisms mediating sensitivity to concentric structure develop at the same rate as those mediating sensitivity to parallel structure.     

Effect of Mg content on Portevin–Le Chatelier band strain in Al–Mg sheet alloys

Experimental measurements of stress drops and band strains in type-B Portevin–Le Chatelier (PLC) bands were carried out for 5xxx series Al–Mg sheets with Mg content between 1.8 and 4.5?wt%. While the stress drops increase with global strain, the band strain values in all the samples follow a common linear relationship with global strain. The results indicate that the type-B PLC band strain is independent of solute content at given strain rate.     

Comment upon ‘"Poor girl": a case of active psychosis’: how therapeutic schemas may limit our work

The paper explores the effect of group participation on depressed women's ‘doing depression’ and ‘doing pleasure’ in Finland over three time periods. Quantitative data and qualitative data are analysed. To assess statistically the differences between the time periods, the Wilcoxon matched-pairs signed-ranks z-test is applied to the quantitative data. Coping with emotions through self-focused attention, depressed women are reluctant to initiate instrumental behaviour. They tend to respond to their lives in a ruminative way. Moving towards pleasure rather than depression characterized women's activities as a result of the group process; they learned to embody health, while envisaging hope for the future. Our emphasis on embodiment allows us to consider agency as a contemporary group therapeutic effect as well as to contextualize psychotherapy research within post-modern thinking. While the findings do not provide an indisputable list of the ways women's activities changed over time or all the advantages of group participation, they do suggest areas for future exploration in connection with depressed women's healthy embodiment in a healing group context and advance an understanding of how the experience and duration of depression can be altered if the public and private boundaries of depressed women's embodied routines are broken down and self-isolation is challenged.     

The Relationship Between Nonclinical Schizotypy and Handedness on Divergent and Convergent Creative Problem-Solving Tasks

Previous research indicated a relationship between hemispherical dominance, the extent of schizotypal tendencies, and creativity. Little research has been conducted to assess the degree of schizotypy in nonclinical samples. The aim of this study was to determine the extent to which measures of multidimensional schizotypy and predominant handedness could predict measures of creativity, as assessed by both divergent and convergent tasks. One hundred and twenty-six participants participated in a quasi-experiment involving tests of predominant handedness, schizotypal tendencies, and divergent and convergent thinking. Results suggest that individuals who scored high on a test for schizotypal tendencies performed better on divergent problem-solving tasks, as opposed to low scoring individuals who performed better on convergent problem-solving tasks. Furthermore, results suggest that there was relationship between handedness on divergent and convergent thinking. There was, however, a relationship between handedness (right hemisphere) on the degree of schizotypal tendencies with left-handed individuals demonstrating greater schizotypal tendencies.     

Using robots to understand animal cognition

In recent years, robotic animals and humans have been used to answer a variety of questions related to behavior. In the case of animal behavior, these efforts have largely been in the field of behavioral ecology. They have proved to be a useful tool for this enterprise as they allow the presentation of naturalistic social stimuli whilst providing the experimenter with full control of the stimulus. In interactive experiments, the behavior of robots can be controlled in a manner that is impossible with real animals, making them ideal instruments for the study of social stimuli in animals. This paper provides an overview of the current state of the field and considers the impact that the use of robots could have on fundamental questions related to comparative psychology: namely, perception, spatial cognition, social cognition, and early cognitive development. We make the case that the use of robots to investigate these key areas could have an important impact on the field of animal cognition.     

Targeting those in need: baseline data from the first English National Health Service (NHS) health trainer service

As part of a wider strategy to reduce health inequalities, England's National Health Service has introduced health trainers (HTs) to facilitate healthier behaviour among disadvantaged groups. This study reports baseline data from the first English HT service: assessing whether the HTs reached socially disadvantaged clients engaging in unhealthy behaviours and describing client belief characteristics relevant to the delivery of the service. Data from 864 clients show that the service reached disadvantaged groups and that those groups were engaging in risky health behaviours. Self-efficacy about changing behaviour was not strong and clients were unlikely to have made explicit behaviour-change plans prior to attending the service. Implications for HT services around targeting those most in need and supporting psychological triggers for change are discussed.     

Using story contexts to bias children’s true and false memories

The effects of embedding standard Deese/Roediger-McDermott (DRM) lists into stories whose context biased interpretation either toward or away from the overall themes of the DRM lists on both true and false recognition were investigated with 7- and 11-year-olds. These biased story contexts were compared with the same children’s susceptibility to false memory illusions using the standard DRM list presentation paradigm. The results showed the usual age effects for true and false memories in the standard DRM list paradigm, where 11-year-olds exhibited higher rates of both true and false recognition compared with the 7-year-olds. Importantly, when DRM lists were embedded in stories, these age effects disappeared for true recognition. For false recognition, although developmental differences were attenuated, older children were still more susceptible to false memory illusions than younger children. These findings are discussed in terms of current theories of children’s false memories as well as the role of themes and elaboration in children’s memory development.     

Let the pigeon drive the bus: pigeons can plan future routes in a room

The task of determining an optimal route to several locations is called the traveling salesperson problem (TSP). The TSP has been used recently to examine spatial cognition in humans and non-human animals. It remains unclear whether or not the decision process of animals other than non-human primates utilizes rigid rule-based heuristics, or whether non-human animals are able to flexibly ‘plan’ future routes/behavior based on their knowledge of multiple locations. We presented pigeons in a One-way and Round-Trip group with TSPs that included two or three destinations (feeders) in a laboratory environment. The pigeons departed a start location, traveled to each feeder once before returning to a final destination. Pigeons weighed the proximity of the next location heavily, but appeared to plan ahead multiple steps when the travel costs for inefficient behavior appeared to increase. The results provide clear and strong evidence that animals other than primates are capable of planning sophisticated travel routes.
