Friend influence on prosocial behavior: The role of motivational factors and friendship characteristics

This study examined motivation (prosocial goals), individual characteristics (sex, ethnicity, and grade), and friendship characteristics (affective quality, interaction frequency, and friendship stability) in relation to middle adolescents' prosocial behavior over time. Ninth- and 10th-grade students (N = 208) attending a suburban, mid-Atlantic public high school and having at least 1 reciprocated friendship were followed for 1 year. Hierarchical regression analyses revealed that a friend's behavior is related to an individual's prosocial goal pursuit, which in turn, is related to an individual's prosocial behavior. Further, the affective quality of a friendship and the frequency with which friends interact moderate relations of a friend's prosocial behavior to an individual's prosocial goal pursuit.     

Becoming syntactic

Psycholinguistic research has shown that the influence of abstract syntactic knowledge on performance is shaped by particular sentences that have been experienced. To explore this idea, the authors applied a connectionist model of sentence production to the development and use of abstract syntax. The model makes use of (a) error-based learning to acquire and adapt sequencing mechanisms and (b) meaning-form mappings to derive syntactic representations. The model is able to account for most of what is known about structural priming in adult speakers, as well as key findings in preferential looking and elicited production studies of language acquisition. The model suggests how abstract knowledge and concrete experience are balanced in the development and use of syntax.     

What Do We Tell the Children? Contrasting the Disclosure Choices of Two HD Families Regarding Risk Statusand Predictive Genetic Testing

Above all else, predictive genetic testing provides information. Gaining insight into the psychosocial effects of this information is a primary goal of genetic counseling. For individuals utilizing predictive genetic testing, the acquisition of genetic information requires choices regarding disclosure within the family. This study uses a phenomenological methodology to explore the contrasting choices of two sets of HD parents regarding the disclosure of genetic risk status to their children. Additionally, the children (now adults) discuss their lived experience growing up with contrasting disclosure dynamics, and their current views regarding the use of predictive genetic testing for themselves. The primary finding of this study is that all of the adult children now express preference for early disclosure of genetic risk and an open/supportive communication style regarding HD. This finding has value for clinicians working with HD families who must make decisions regarding disclosure issues related to predictive genetic testing.     

Evaluating three criteria for establishing cue-search hierarchies in inferential judgment

The authors identify and provide an integration of 3 criteria for establishing cue-search hierarchies in inferential judgment. Cues can be ranked by information value according to expected information gain (Bayesian criterion), cue-outcome correlation (correlational criterion), or ecological validity (accuracy criterion). All criteria significantly predicted information acquisition behavior; however, in 3 experiments, the most successful predictor was the correlational criterion (followed by the Bayesian). Although participants showed sensitivity to task constraints, searching for less information when it was more expensive (Experiment 1) and when under time constraints (Experiment 2), concomitant changes in the relative frequency of acquisition of cues with different information values were not observed. A rational analysis illustrates why such changes in the frequency of acquisition would be beneficial, and reasons for the failure to observe such behavior are discussed.     

Retrograde enhancement of kinesthetic memory by alcohol and by glucose

Several studies have reported that administration of a low dose of alcohol is capable of retrograde enhancement of memory. It has been postulated that the neurobiological mechanisms underlying this effect may involve the liberation of glucose and/or activation of reward centers. Here the effects of a low dose of alcohol were compared to those of glucose on kinesthetic memory. Mood and blood glucose levels were also measured. Compared with a placebo, both glucose and alcohol significantly enhanced kinesthetic memory performance. Only glucose ingestion resulted in significantly elevated blood glucose levels. The three groups' mood scores were statistically indistinguishable. Low-dose alcohol consumption does not result in the release of glucose nor does it affect any aspect of mood, at least as measured here. These results confirm that kinesthetic memory can be improved by administration of alcohol and extend the range of tasks which are sensitive to enhancement by glucose.     

Promoting positive body image among university students: A collaborative pilot study

The purpose of the present study was to pilot a prevention program designed to promote positive body image among university students. Thirty-seven undergraduate students from three Canadian universities were recruited to participate in the study. They were selected from a pool of students enrolled in a peer health education program facilitated by the university-based health promotion staff. Borrowing from the tenets of the non-specific vulnerability stressor model and the disease-specific social cognitive theory, the intervention focused on media literacy, self-esteem enhancement strategies, stress management skills and ways to recognize healthy versus unhealthy relationships. Separate ANOVAs revealed that participants reported significant improvements in body satisfaction and reductions in the internalization of media stereotypes between the baseline and post-program period. The program received a favorable response from the participating students, who appreciated the face-to-face format of the intervention, and from the university staff who expressed interest in embedding the strategies into their routine peer mentoring training activities. Limitations of the study and suggestions for future research are discussed.     

Low neuroticism and high hedonistic traits for female internet child pornography consumers

Limited research has attempted to identify and understand the personality characteristics of female consumers of Internet child pornography (ICP). In the current study, female respondents (N = 162) from the Seigfried et al. study were analyzed to determine if personality characteristics differed between female users (n = 10, 6.2%) and female non-users (n = 152, 93.8%) of ICP. An exploratory backward stepwise (Wald) logistic regression revealed a predictive model, with female ICP consumers scoring: low on neuroticism, high on moral choice hedonism, and self-reporting a non-white racial identity. The relationship between female ICP consumption, neuroticism, hedonism, and race are discussed, along with the study's limitations and future research suggestions in the area of computer deviance.     

Maternal Depression,Maternal Expressed Emotion,and Youth Psychopathology

Across development, maternal depression has been found to be a risk factor for youth psychopathology generally and youth depression specifically. Maternal Expressed Emotion (EE) has been examined as a predictor of outcome among youth with depression. The present study explored the associations between youth psychopathology and two predictors–maternal depression within the child’s lifetime and maternal EE–in a study of children at risk for depression. One hundred and seventy-one youth, ages 8–12, and their mothers participated. To assess maternal and youth psychopathology, dyads were administered structured diagnostic assessments, and mothers and children completed self-report measures of their own depressive symptoms. In addition, mothers completed the Achenbach Child Behavior Checklist–Parent Report Version (CBCL) for their children. Maternal EE was assessed based on the Five Minute Speech Sample. History of maternal depression was associated with high maternal EE, and the combination of maternal depression history and maternal EE was associated with children’s own reports of higher depressive symptoms. Current maternal depressive symptoms were associated with mothers’ reports of children’s Internalizing scores on the CBCL, and maternal depression history, current maternal depressive symptoms, and maternal EE were strongly associated with mothers’ reports of children’s Externalizing and Total Problem scores on the CBCL. History of maternal depression and a rating of high or borderline Critical EE (characterized by maternal critical comments and/or reports of a negative relationship) were independently associated with children’s depression diagnoses.
