AN EVALUATION OF THE NUMBER OF PRESENTATIONS OF TARGET SOUNDS DURING STIMULUS—STIMULUS PAIRING TRIALS

We evaluated the differential effects of 2 variations of a stimulus–stimulus pairing procedure on the vocalizations of 2 children with autism. For both participants, presenting 1 sound per pairing trial resulted in a higher rate of vocalizations than 3 sounds per pairing trial.     

A TRANSLATIONAL EVALUATION OF THE INTERPOLATED REINFORCEMENT PROCEDURE WITH YOUNG CHILDREN

The interpolated reinforcement procedure (IRP) involves the deliberate continuous reinforcement of a previously intermittently reinforced behavior prior to implementing extinction. Basic research on the IRP has produced equivocal findings, and applied research has suffered from methodological limitations. The present study was an evaluation of the IRP with typically developing young children and a nonclinical target behavior. The IRP was demonstrated in only two of five participants. The results are discussed in the context of the IRP's clinical utility given the unreliability of the finding. Copyright © 2012 John Wiley & Sons, Ltd.     

“Do You Trust Him?” Children’s Trust Beliefs and Developmental Trajectories of Aggressive Behavior in an Ethnically Diverse Sample

This study investigated the role of trust beliefs (i.e., trustworthiness, trustfulness) on aggression trajectories in a four-wave longitudinal study using an ethnically diverse sample of 8- to 11-year-old children (N?=?1,028), as well as the risk profiles of low trust beliefs and low socioeconomic status on aggression trajectories. At Time 1 to Time 4, teachers provided ratings of overt aggressive behavior. At Time 1, children’s trust beliefs were assessed by a sociometric peer nomination instrument and derived using social relations analysis. Latent growth curve analysis revealed five trajectories of aggressive behavior: high-stable, medium-stable, low-stable, increasing, and decreasing. As hypothesized, children in the high-stable trajectory were perceived as less trustworthy than children in the low-stable, medium-stable, and increasing trajectories. Children in the high-stable trajectory were less trustful than children in the low-stable trajectory and had a significantly higher risk profile (i.e., low trust beliefs and low SES) compared to children in the low-stable trajectory. Our findings indicate that the developmental course of aggression during middle childhood is predicted by children’s trustworthiness and trustfulness. A risk profile of low trust and low socioeconomic status contributes to high-stable aggression trajectories.     

Postmodern Masculinities and the Eunuch

This research examines the recent rise of the eunuch within several sociological contexts. The contention of this article is that present images of masculine sexuality have inadvertently made the effigy of the eunuch more permissible, albeit, unstated. In addition, as a form of sexual deviance, this practice relies on both individual pathologies and communities for membership. Recent technological advances in the computer industry have simplified access to like-minded individuals fostering fellowship. Using both primary and secondary sources of data, individual motivations to becoming a eunuch are examined.     

The role of problem solving in complex intraverbal repertoires

We examined whether typically developing preschoolers could learn to use a problem-solving strategy that involved self-prompting with intraverbal chains to provide multiple responses to intraverbal categorization questions. Teaching the children to use the problem-solving strategy did not produce significant increases in target responses until problem solving was modeled and prompted. Following the model and prompts, all participants showed immediate significant increases in intraverbal categorization, and all prompts were quickly eliminated. Use of audible self-prompts was evident initially for all participants, but declined over time for 3 of the 4 children. Within-session response patterns remained consistent with use of the problem-solving strategy even when self-prompts were not audible. These findings suggest that teaching and prompting a problem-solving strategy can be an effective way to produce intraverbal categorization responses.     

Response interruption and redirection for vocal stereotypy in children with autism: a systematic replication

This study systematically replicated and extended previous research on response interruption and redirection (RIRD) by assessing instructed responses of a different topography than the target behavior, percentage of session spent in treatment, generalization of behavior reduction, and social validity of the intervention. Results showed that RIRD produced substantial decreases in vocal stereotypy. Limitations of this study were that behavior reduction did not generalize to novel settings or with novel instructors and that appropriate vocalizations did not improve.     

Assessment Center Practices in South Africa

Despite the popularity of assessment centers (AC) in South Africa, no recent study exists that describes AC practices in that region. Given this research gap, we conducted a survey study that analyzes the development, execution, and evaluation of ACs in N=43 South African organizations. We report findings regarding AC design, job analysis and job requirements assessed, target groups and positions of the participants after the AC, number and kind of exercises used, additional diagnostic methods used, assessors and characteristics considered in constitution of the assessor pool, observational systems and rotation plan, characteristics, contents, and methods of assessor training, types of information provided to participants, data integration process, use of self‐ and peer‐rating, characteristics of the feedback process, and features after the AC. Finally, we compare the results with professional suggestions to identify pros and cons in current South African AC practices and offer suggestions for improvement.     

Psychological processes in young bullies versus bully‐victims

Some children who bully others are also victimized themselves (“bully‐victims”) whereas others are not victimized themselves (“bullies”). These subgroups have been shown to differ in their social functioning as early as in kindergarten. What is less clear are the motives that underlie the bullying behavior of young bullies and bully‐victims. The present study examined whether bullies have proactive motives for aggression and anticipate to feel happy after victimizing others, whereas bully‐victims have reactive motives for aggression, poor theory of mind skills, and attribute hostile intent to others. This “distinct processes hypothesis” was contrasted with the “shared processes hypothesis,” predicting that bullies and bully‐victims do not differ on these psychological processes. Children (n = 283, age 4–9) were classified as bully, bully‐victim, or noninvolved using peer‐nominations. Theory of mind, hostile intent attributions, and happy victimizer emotions were assessed using standard vignettes and false‐belief tasks; reactive and proactive motives were assessed using teacher‐reports. We tested our hypotheses using Bayesian model selection, enabling us to directly compare the distinct processes model (predicting that bullies and bully‐victims deviate from noninvolved children on different psychological processes) against the shared processes model (predicting that bullies and bully‐victims deviate from noninvolved children on all psychological processes alike). Overall, the shared processes model received more support than the distinct processes model. These results suggest that in early childhood, bullies and bully‐victims have shared, rather than distinct psychological processes underlying their bullying behavior.     

Vigilance and Avoidance of Threat in the Eye Movements of Children with Separation Anxiety Disorder

The vigilance-avoidance attention pattern is found in anxious adults, who initially gaze more at threatening pictures than nonanxious adults (vigilance), but subsequently gaze less at them than nonanxious adults (avoidance). The present research, using eye tracking methodology, tested whether anxious children show the same pattern. Children with separation anxiety disorder or no mental disorder viewed pairs of pictures, while the direction of their gaze was tracked. Each picture pair showed one picture of a woman separating from a child, the other picture of a woman reuniting with a child. The results supported the vigilance-avoidance model in children. Although the two groups’ gaze direction did not differ during the first second of viewing, anxious children gazed significantly more at separating (threatening) pictures than nonanxious children after a period of 1 s. But after 3 s the pattern reversed: anxious children gazed significantly less at the separating pictures than nonanxious children.
