Use of 3-dimensional body scans for body-image research

This preliminary study explored the use of highly realistic 3-dimensional body-scan images as a potential tool, taking advantage of a much more specific and expanded representation of the entire body. Traditionally, body-image research makes use of various contour drawing scales whose 2-dimensional figures increase proportionately and do not match the shape of many women. The study tested whether body-scanned images (N = 85) could be consistently "matched" to individual figures on a contour drawing scale. Internal consistency and interrater reliability were calculated and high coefficients were observed (alpha = .97, kappa = .80). The potential of utilizing 3-dimensional images either as more realistic somatotypes in contour-rating scales or as a measurement of body-image satisfaction using computer manipulation of a digital image is discussed.     

Child Psychosocial Adjustment and Parenting in Families Affected by Maternal HIV/AIDS

Child adjustment and parenting were examined in twenty-three 9–16-year-old youth from families affected by maternal HIV infection and 20 same-age peers whose mothers were not infected. Children whose mothers were seropositive reported significantly more externalizing problems. Infected mothers reported less age-appropriate supervision/monitoring relative to non-infected mothers. Better mother-child relationship quality and less impairment in parental supervision/monitoring of age-appropriate youth behaviors were associated with fewer externalizing difficulties among the HIV-positive group only. Similarly, only among HIV-infected mothers was refraining from engaging in inconsistent disciplinary tactics associated with lower reports of internalizing and externalizing problems. These data highlight the promise of programs targeting parenting skills to prevent or ameliorate child difficulties.     

Social cues for creativity: The impact of behavioral mimicry on convergent and divergent thinking

We present behavioral mimicry as a social cue for creative thinking. Specifically, we argue that being mimicked by an interaction partner cues convergent thinking by signalling a social opportunity for collaboration, while not being mimicked cues divergent thinking by signalling a social demand for improvisation and innovation. To test this theory, we experimentally manipulated whether individuals were subtly mimicked or not by an experimenter during a 5 min social interaction, and subsequently measured participants’ capacity for convergent thinking (Experiment 1) and divergent thinking (Experiment 2). The results point to the importance of understanding how social relationships influence the creative processes and contributes to the growing understanding of the social function of behavioral mimicry.     

Cooperation versus competition in a mass emergency evacuation: A new laboratory simulation and a new theoretical model

Virtual reality technology is argued to be suitable to the simulation study of mass evacuation behavior, because of the practical and ethical constraints in researching this field. This article describes three studies in which a new virtual reality paradigm was used, in which participants had to escape from a burning underground rail station. Study 1 was carried out in an immersion laboratory and demonstrated that collective identification in the crowd was enhanced by the (shared) threat embodied in emergency itself. In Study 2, high-identification participants were more helpful and pushed less than did low-identification participants. In Study 3, identification and group size were experimentally manipulated, and similar results were obtained. These results support a hypothesis according to which (emergent) collective identity motivates solidarity with strangers. It is concluded that the virtual reality technology developed here represents a promising start, although more can be done to embed it in a traditional psychology laboratory setting.     

Delinquent peer affiliation and conduct problems: A twin study

Many putative environmental risks correlate with individuals' genotypes. The association between delinquent peer affiliation and conduct problems may occur because of shared genetic liability. Five hundred fifty three monozygotic and 558 dizygotic twin pairs, aged 11 to 18 years, were assessed for delinquent peer affiliation and conduct problems. The authors investigated whether genes contribute to both delinquent peer affiliation and the correlation between delinquent peer affiliations and conduct problems. Delinquent peer affiliation was influenced by genetic, shared environmental, and nonshared environmental factors; genetic factors also contributed to the correlation between delinquent peer affiliations and conduct problems, providing evidence for genotype-environment correlation. The magnitude of the genetic variance of conduct problems was contextually dependent on levels of delinquent peer affiliation and was greater at higher levels of delinquent peer affiliation.     

Parentification and Maternal HIV Infection: Beneficial Role or Pathological Burden?

Parentification, along with parenting and child adjustment, were examined in 23 9-through 16-year-old youth from families affected by maternal HIV infection and 20 same-age peers whose mothers were not infected. Children whose mothers were HIV-positive reported to more often engage in parental role behaviors, relative to children of HIV-negative mothers. This difference remained even after controlling for the effects of current drug use, number of adults per child in the household, and marital status. Findings revealed a beneficial relationship between parentification and both child adjustment and parenting, particularly among families affected by maternal HIV infection. When relationships were examined separately by HIV status, the pattern of results suggested that parentification, which involves increased emotional closeness, rather than role-related tasks, which may involve increased responsibility of household maintenance, seems to foster an association with concurrent positive parenting and child adjustment among families coping with HIV/AIDS. Directions for future research, including the need for methodological advances in the field are discussed.     

Exploring Factors Related to Young Children’s Word-Meaning Derivations During Read-Alouds

This study explores how child and text clues were related to 31 kindergarteners’ word-meaning derivation outcomes for 372 words presented in books read aloud to children. Data were analyzed using a multilevel, cross-classification, ordered logit model. Children showed no word-meaning derivation 40% of the time, indicating a need for instruction. Better word-meaning outcomes were related to text factors (written text clues in close proximity to the word) and child factors (literal comprehension and metacognition). Thus, using text with written clues in close proximity to the word and building children's literal comprehension and metacognition may improve word-meaning derivation.
