Bystander Responses to Public Episodes of Child Abuse

Bystander responses to public episodes of child abuse were surveyed among 269 self reported witnesses. Respondents completed an 80-item self-report questionnaire which inquired into a broad range of events, experiences, and behaviors surrounding naturally occurring incidents of perceived child abuse witnessed in public places. Almost one-half of the sample reported having witnessed at least one event of child abuse in public, but only one out of four witnesses acted to intervene. Data analyses identified 40 statistically significant variables across four categories: characteristics of the bystander, situation, victim, and perpetrator. Results were generally consistent with predictions and findings from previous research on bystander intervention, but a number of new and significant variables were identified that characterized intervention events. Direct and indirect forms of intervention were also distinguished. Implications of the findings are discussed, and educating people to intervene on behalf of abused children is proposed.     

The effects of differential negative reinforcement of other behavior and noncontingent escape on compliance

The present study evaluated the effects of noncontingent escape and differential negative reinforcement of other behavior in reducing problem behaviors and increasing compliance in 2 children with disabilities. Results showed that both methods reduced problem behavior and increased compliance for both children.     

Induction when rats lick for 1% liquid-sucrose reinforcement

Previous research reported that rats responding for 1% liquid-sucrose reinforcement when 32% sucrose reinforcement is upcoming will decrease their response rate (contrast) if licking is the dependent measure and increase their response rate (induction) if pressing a lever is the dependent measure. The present study investigated whether induction could be observed when licking served as the dependent measure and whether induction in lever pressing and contrast in licking behaviour could be concurrently observed. Experiment 1 found induction when rats licked to earn the rewards but consumed them at a location separate from the spout licked to earn them. Experiment 2 also found induction when rats earned (and consumed) rewards by licking the same spout throughout the session. Experiment 3 separately measured instrumental lever pressing for sucrose rewards and licking the sucrose during the reward period. We found that both measures increased for 1% sucrose when 32% sucrose reinforcement was upcoming. The present results indicate that the type of response is not the sole determinant of whether contrast or induction is observed. Rather, they suggest that other procedural details, such as the location of reinforcer delivery, influence which effect is observed. The results also indicate that associative processes underlie the appearance of induction in responding for 1% sucrose.     

A preliminary study of perfectionism and loneliness as predictors of depressive and anxious symptoms in Latinas: a top-down test of a model

In the present study, we used a top-down approach to examine perfectionism and loneliness as additive sociocognitive predictors of depressive and anxious symptoms in a sample of 121 Latina college students. Consistent with expectations, we found perfectionism and loneliness to be associated with both depressive and anxious symptoms. In addition, results of conducting hierarchical regression analyses indicated that certain dimensions of perfectionism, especially doubts about actions, accounted for significant variance in both depressive and anxious symptoms. Moreover, the inclusion of loneliness as a predictor was found to predict additional unique variance in both depressive and anxious symptoms beyond what was accounted for by perfectionism. Implications of the present findings for future research on negative affective conditions in Latinas are discussed.     

Artificial time constraints on the Iowa Gambling Task: the effects on behavioural performance and subjective experience

In the last decade, the Iowa Gambling Task (IGT) has become a widely employed neuropsychological research instrument for the investigation of executive function. The task has been employed in a wide range of formats, from 'manual' procedures to more recently introduced computerised versions. Computer-based formats often require that responses on the task should be artificially delayed by a number of seconds between trials to collect skin-conductance data. Participants, however, may become frustrated when they want to select from a particular deck in the time-limited versions--so that an unintended emotional experience of frustration might well disrupt a task presumed to be reliant on emotion-based learning. We investigated the effect of the various types of Iowa Gambling Task format on performance, using three types of task: the classic manual administration, with no time limitations; a computerised administration with a 6-s enforced delay; and a control computerised version which had no time constraints. We also evaluated the subjective experience of participants on each task. There were no significant differences in performance, between formats, in behavioural terms. Subjective experience measures on the task also showed consistent effects across all three formats-with substantial, and rapidly developing, awareness of which decks were 'good' and 'bad.'     

Psychological factors and use of antiepileptic drugs: pilot work using an objective measure of adherence

Given the current emphasis on the "concordance" prescribing model, a study was designed to determine the influence of patients' beliefs about epilepsy, beliefs about medication and a range of neuroepilepsy variables on drug adherence among a sample of epilepsy patients. A special feature of the study was the use of a credible objective measure of drug adherence. Psychological health was also assessed. Thirty-seven patients were recruited from a local epilepsy clinic. Beliefs about epilepsy (illness representations), beliefs about epilepsy medication, anxiety, depression, neuroepilepsy status and adherence were all measured. Data were collected via clinical interview and questionnaire methods. Adherence with drug treatment was determined by an objective measure using low-dose phenobarbital as an indicator of adherence and, or, measurement of antiepileptic drug levels. Neither illness representations nor beliefs about epilepsy drugs were related to adherence. With the exception of time since last seizure, which was positively related to adherence, neuroepilepsy variables were unrelated to adherence. A number of significant associations between cognitive representations of epilepsy and mood were found.     

EVALUATIONS OF SEXY WOMEN IN LOW- AND HIGH-STATUS JOBS

We hypothesized that women who dress in a sexy versus business-like manner evoke negative emotions and perceptions of lesser competence if employed in high- (but not low-) status jobs. Male and female undergraduates evaluated a videotaped female target whose physical attractiveness was held constant, but who was (a) dressed in sexy or business-like attire and (b) allegedly either a manager or a receptionist. Participants exhibited more negative affect toward the sexily attired manager and rated her as less competent than the neutrally attired manager. This effect was fully mediated by emotional reactions. In contrast, the appearance manipulation had no effect on emotions toward or competence ratings of the receptionist. These findings suggest that a sexy self-presentation harms women in high-, but not low-, status jobs.     

Trajectories of social withdrawal from grades 1 to 6: prediction from early parenting, attachment, and temperament

From 1,092 children in the NICHD Study of Early Child Care and Youth Development, the authors identified 3 trajectory patterns of social withdrawal from teacher reports in Grades 1-6: a normative consistently low group (86%), a decreasing group (5%) with initially high withdrawal that decreased, and an increasing group (9%) with initially low withdrawal that increased. Prediction models supported the role of early dysregulated temperament, insensitive parenting, and attachment. Preschool shy temperament was a specific pathway to decreasing withdrawal, and poor inhibitory control was a specific pathway to increasing withdrawal. Children on the increasing pathway were more lonely, solitary, and were excluded by peers. Results suggest differentiated pathways to varying trajectories of social withdrawal and highlight the importance of identification of longitudinal patterns in relation to risk.     

Changes in Pronominal Usage in a Classroom Situation

Changes in pronominal usage of students were investigated in a classroom situation where attention to usage was heightened by instructor use of 'she' as the generic singular, and by instructor assessment of reactions to the practice. Two classes (N = 74) constituted the experimental group. Analyses of pronominal usage in the written work of students (compared to a control group, N=20) and questionnaires to obtain student reaction to instructor usage and student views on language usage were the principal measures used. Results indicated a change in use of pronouns with more specific use of "he," a reduction of use of "he" as the generic singular, and use of "she" as a generic. Results indicate that pronominal usage is susceptible to change.
