Research participants telling the truth about their lives: the ethics of asking and not asking about abuse

Most discussions of the ethics of self-report research on abuse and interpersonal violence focus on the risks of asking participants about their experiences. An important element of the cost-benefit analysis--the costs of not asking about child abuse--has largely been ignored. Furthermore, little research has been conducted on the costs and benefits of child abuse research, leaving researchers to make decisions based on individual beliefs about such issues as the prevalence of abuse, the likelihood of disclosure, the effects of child abuse, and the ability of abuse survivors to give informed consent. The authors suggest that these beliefs tend to overemphasize survivors' vulnerability and ignore the costs of avoiding asking about abuse. In fact, these beliefs may reinforce societal avoidance of abuse and ultimately harm abuse survivors.     

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.     

Positive affectivity predicts successful and unsuccessful adaptation to stress

This study examined adaptation to work stress among public school teachers (n = 267). Regression analyses tested whether positive affect predicted successful and unsuccessful adaptation to stress (viz., resilience and burnout, respectively) after controlling for demographic characteristics and work stress. Positive affect was largely correlated with resilience (r = .65, p < .001) and burnout (r = ?.57, p < .001). The regression of resilience showed that positive affect had a direct effect (β = .66, p < .001) and the total model explained 44 % of the variance (R ² Change = 37 %). In the regression of burnout, positive affect also had a direct effect (β = ?.41, p < .001) and the total model explained 52 % of the variance (R ² Change = 14 %). Further analyses found no significant interaction between work stress and positive affect, but revealed that positive affect completely mediated the effect of work stress on resilience. Results provide support for the broaden-and-build theory of positive emotions, particularly the theory’s building and undoing effects.     

The Interpersonal Model of Health Anxiety: Testing predicted paths and model specificity

Health anxiety involves persistent worry about one’s health and is characterized by dysfunctional interpersonal processes such as excessive health-related reassurance-seeking and feelings of alienation from others. Cognitive-behavioral models largely ignore cyclical, interpersonally averse behaviors and social cognitions observed amongst health anxious individuals. The Interpersonal Model of Health Anxiety (IMHA) proposes health anxiety is maintained through activated anxious attachment insecurities, which drive frequent, but ineffective, health-related reassurance-seeking from others. Such excessive health-related reassurance-seeking leads to health-related alienation and beliefs others are unconcerned about one’s perceived health problems. Feeling alienated from others fuels further health-related worry, resulting in continued self-defeating attempts at health-related reassurance-seeking. The present study offers the first comprehensive articulation and test of the IMHA. Using a cross-sectional design and 107 undergraduates, path analysis supported five of six hypothesized paths in the model; all paths except that from anxious attachment to health-related reassurance-seeking were significant and in the expected direction. Specificity tests suggested anxious attachment was more central than avoidant attachment to the IMHA. The present test of the IMHA as a single, coherent model provides a conceptual foundation for future research on interpersonal processes in health anxiety. Clinical implications are discussed.
