Ethnic and Gender Differences in Distress Among Anglo American, African American, Japanese American, and Mexican American Spousal Caregivers of Persons with Dementia

Distress, coping, and social resources were compared in a sample of 202 Japanese-, Anglo-, African-, and Mexican American spousal caregivers of persons with dementia using a Stress-Coping model. Both ethnicity and gender showed differential effects on the outcome and on the moderating variables. Female caregivers in all ethnic groups reported significantly higher levels of psychiatric symptomatology. All 4 ethnic groups reported high rates of psychological distress, with Mexican Americans reporting significantly higher rates of depression than Anglo or African Americans. Ethnicity was related to (1) the kind of caregiving appraisals (spiritual, pessimistic, and lack of support), (2) coping styles (escape-avoidance and seeking social support), and (3) social support. African Americans were more likely to be spiritual appraisers, to have more positive appraisals, and to have more social support available to them. Gender differences were evident on 4 out of the 6 caregiver appraisals, but none of the coping styles. Although males tended to have more perfectionistic appraisals, they were also more likely to view caregiving with a less negative and more self-efficacious outlook.     

An Evaluation of the Relative Effectiveness of Function-Based Consequent and Antecedent Interventions in a Preschool Setting

Although there is substantial functional behavioral assessment (FBA) literature suggesting that function-based interventions are effective for improving problem behavior, only a limited number of studies have examined the effectiveness of function-based antecedent versus consequent interventions. Additionally, although there has been a recent increase in the number of studies conducted in the K–12 school setting, only a limited number of studies have included children in the preschool setting. The present study extends existing literature by examining the effectiveness of function-based antecedent versus consequent interventions for reducing problem behavior and increasing appropriately engaged behavior for preschool children without cognitive disabilities. Following an FBA of 4 children, the effectiveness of a function-based antecedent (i.e., noncontingent reinforcement [NCR]) was compared with a function-based consequent (i.e., differential reinforcement of alternative behavior [DRA]) intervention using an alternating treatments design. Results indicated that both function-based NCR and DRA were effective for decreasing problem behavior and increasing appropriately engaged behavior, with function-based NCR being more effective than DRA for 2 of 4 participants.     

Automated vision occlusion-timing instrument for perception–action research

Vision occlusion spectacles are a highly valuable instrument for visual-perception–action research in a variety of disciplines. In sports, occlusion spectacles have enabled invaluable knowledge to be obtained about the superior capability of experts to use visual information to guide actions within in-situ settings. Triggering the spectacles to occlude a performer’s vision at a precise time in an opponent’s action or object flight has been problematic, due to experimenter error in using a manual buttonpress approach. This article describes a new laser curtain wireless trigger for vision occlusion spectacles that is portable and fast in terms of its transmission time. The laser curtain can be positioned in a variety of orientations to accept a motion trigger, such as a cricket bowler’s arm that distorts the lasers, which then activates a wireless signal for the occlusion spectacles to change from transparent to opaque, which occurs in only 8 ms. Results are reported from calculations done in an electronics laboratory, as well as from tests in a performance laboratory with a cricket bowler and a baseball pitcher, which verified this short time delay before vision occlusion. In addition, our results show that occlusion consistently occurred when it was intended—that is, near ball release and during mid-ball-flight. Only 8% of the collected data trials were unusable. The laser curtain improves upon the limitations of existing vision occlusion spectacle triggers, indicating that it is a valuable instrument for perception–action research in a variety of disciplines.     

If the Television Program Bleeds, Memory for the Advertisement Recedes

In public surveys, the most common complaint about television is the amount of violence depicted on the screen. More than half the programs shown on television are violent, and hundreds of studies have shown that viewing TV violence causes an increase in societal violence. Nevertheless, advertisers continue to sponsor violent programs. For an advertisement to be effective, people should be able to remember the brand advertised and the message in the advertisement. This article reviews the effect of TV violence on memory for ads. A meta-analysis integrating the results from 12 studies involving more than 1,700 participants shows that TV violence impairs memory for ads. The impairment occurs for males and females, for children and adults, and for people who like and do not like to watch TV violence. These results suggest that sponsoring violent programs might not be a profitable venture for advertisers.     

A selectionist explanation for the success and failures of science

I argue that van Fraassen’s selectionist explanation for the success of science is superior to the realists’ explanation. Whereas realists argue that our current theories are successful because they accurately reflect the structure of the world, the selectionist claims that our current theories are successful because unsuccessful theories have been eliminated. I argue that, unlike the explanation proposed by the realist, the selectionist explanation can also account for the failures of once successful theories and the fact that sometimes two competing theories are both equally successful.

I wish I were a warrior: the role of wishful identification in the effects of violent video games on aggression in adolescent boys

This study tested the hypothesis that violent video games are especially likely to increase aggression when players identify with violent game characters. Dutch adolescent boys with low education ability (N=112) were randomly assigned to play a realistic or fantasy violent or nonviolent video game. Next, they competed with an ostensible partner on a reaction time task in which the winner could blast the loser with loud noise through headphones (the aggression measure). Participants were told that high noise levels could cause permanent hearing damage. Habitual video game exposure, trait aggressiveness, and sensation seeking were controlled for. As expected, the most aggressive participants were those who played a violent game and wished they were like a violent character in the game. These participants used noise levels loud enough to cause permanent hearing damage to their partners, even though their partners had not provoked them. These results show that identifying with violent video game characters makes players more aggressive. Players were especially likely to identify with violent characters in realistic games and with games they felt immersed in.
