GENERALIZATION AND MAINTENANCE OF PRESCHOOL CHILDREN'S SOCIAL SKILLS: A CRITICAL REVIEW AND ANALYSIS

This paper summarizes the results of a retrospective review of generalization in the context of social skills research with preschool children. A review of studies from 22 journals (1976 to 1990) that assessed generalization as part of social interaction research provided information concerning the prevalence of studies that have assessed generalization, common practices concerning the production and assessment of generalization, and the overall success of obtaining generalization and maintenance of social behaviors. A comparison of the most and least successful studies, with respect to generalization, revealed some differences concerning the practices employed by studies within each group. Differences differentially related to the production of generalization are discussed and recommendations are provided to guide and support future research efforts.     

Why It Can't Happen to Me: The Base Rate Matters,But Overestimating Skill Leads to Underestimating Risk1

Undergraduates (N = 330) estimated their risk for aversive events (e.g., motor vehicle accident), in which we varied personal control (e.g., driver = self or other) and bogus base rates (high vs. low). Base rate data influenced risk estimates, but people underestimated their risk if they were the agent (e.g., the driver) rather than if another person was the agent. Justifications for estimates suggested that the base rate was perceived to be the risk for the average person. Most people then adjusted their estimates for a negative outcome downward because they believed that they were better than average on a skill (e.g., driving skill) that was perceived to be causally related to the event.     

Some Effects of Crowding in a Prison Environment1

Inmates at a federal correctional institution were examined for their criterion of what constitutes overcrowding. In general, inmates who were housed under highly crowded conditions exhibited less tolerance of overcrowding than did those who were housed under relatively less crowded conditions. Higher crowding also yielded more negative affective responses to the physical environment. This relationship existed only with respect to a social-density measure of crowding and not for a spatial-density measure.     

Consultative services in the schools: A model

A model Child Evaluation Center was established in a regular public school to demonstrate alternative methods for providing psychoeducational services. In addition to its service/demonstration function, the center functioned as a psychoeducational field training clinic for the training of school psychologists. The center was successful in encouraging teachers to utilize consultative services, and, in the process, reducing the number of referrals for formal psychological evaluation.     

When auditory presentations should and should not be a component of multimedia instruction

Based on cognitive load theory, two experiments investigated the conditions under which audiovisual‐based instruction may be an effective or an ineffective instructional technique. Results from Experiment 1 indicated that visual with audio presentations were superior to equivalent visual‐only presentations. In this experiment, neither the auditory nor the visual material could be understood in isolation. Both sources of information were interrelated and were essential to render the material intelligible. In contrast, Experiment 2 demonstrated that a non‐essential explanatory text, presented aurally with similar written text contained in a diagram, hindered learning. This result was obtained because when compared to a diagram only format, the aural material was unnecessary and therefore created a redundancy effect. Differences between groups were stronger when information was high in complexity. It was concluded that the effectiveness of multimedia instruction depends very much on how and when auditory information is used. Copyright © 2003 John Wiley & Sons, Ltd.     

Spirituality and Health Outcomes in the Elderly

The purpose of this mail survey was to examine the relationship of attitudinal and behavioral measures of spirituality to physical and mental health outcomes in a sample of elderly community residents. Frequency of prayer, importance of faith, and reliance on religion for their coping were compared for their association with eight categories of physical and mental health. All three measures, prayer, faith and religious coping, correlated strongly with positive mental health, but not with the other seven physical health categories. Multiple regression analyses indicated importance of one's faith had the strongest association with positive mental health, even after controlling for the effect of other significant variables, age and education. The behavioral measure of prayer was a component of importance of faith to mental health, with no independent impact. This study highlights attitudes rather than practices, as the stronger spiritual variables related to mental health in the elderly.     

The effects of transcranial direct current stimulation (tDCS) on multitasking performance and oculometrics

Multitasking is the ability to perform more than one task simultaneously. The need to multitask is common in many industries especially within the military with tasks such as air traffic controllers, cyber defense operators and image analysts. However, as the time on task increases, information throughput can become overwhelming resulting in a performance decrement. Through task prioritizing, the operator is able to maintain performance on specific subtasks in which they selected as high importance while other subtasks experience a decrement. The objective of this study was to evaluate the effects of transcranial direct current stimulation (tDCS) applied to the left dorsolateral prefrontal cortex (ldLPFC) on information processing capabilities to improve individual and overall multitasking performance while performing the multi-attribute task battery (MATB). Two groups of 8 participants each received either 2 mA of anodal or sham tDCS while performing MATB. In addition, eye tracking was implemented to record eye movement patterns. In doing so, we were able to determine how much time the operator allocated to each of the subtasks within MATB and how their task priorities changed as workload demands increased. The findings provided evidence that 2 mA of anodal tDCS during MATB significantly improved overall information throughput compared to the sham group. With respect to the individual subtasks, communication and system monitoring displayed the greatest enhancement with anodal tDCS. Our data suggests that tDCS could be a useful tool to enhance information processing capabilities during a multitasking paradigm resulting in improved processing capabilities and information throughput.     

Aboriginal language knowledge and youth suicide

This brief report details a preliminary investigation into how community-level variability in knowledge of Aboriginal languages relate to “band”-level measures of youth suicide. In Canada, and, more specifically, in the province of British Columbia (BC), Aboriginal youth suicide rates vary substantially from one community to another. The results reported demonstrate that not only did this simple language-use indicator prove to have predictive power over and above that of six other cultural continuity factors identified in previous research, but also that youth suicide rates effectively dropped to zero in those few communities in which at least half the band members reported a conversational knowledge of their own “Native” language.
