Distractor clustering enhances detection speed and accuracy during selective listening

The effects of distractor clustering on target detection were examined in two experiments in which subjects attended to binaural tone bursts of one frequency while ignoring distracting tones of two competing frequencies. The subjects pressed a button in response to occasional target tones of longer duration (Experiment 1) or increased loudness (Experiment 2). In evenly spaced conditions, attended and distractor frequencies differed by 6 and 12 semitones, respectively (e.g., 2096-Hz targets vs. 1482- and 1048-Hz distractors). In clustered conditions, distractor frequencies were grouped; attended tones differed from the distractors by 6 and 7 semitones, respectively (e.g., 2096-Hz targets vs. 1482- and 1400-Hz distractors). The tones were presented in randomized sequences at fixed or random stimulus onset asynchronies (SOAs). In both experiments, clustering of the unattended frequencies improved the detectability of targets and speeded target reaction times, Similar effects were found at fixed and variable SO As. Results from the analysis of stimulus sequence suggest that clustering improved performance primarily by reducing the interference caused by distractors that immediately preceded the target.     

Ignorance is not a victimless crime: The case of the caring teacher,part 2

Confusion about the mandated reporting of child abuse was discovered in a case study to be widespread, including at the state level. Such extensive confusion serves to keep citizens from both seeing the depth of suffering to which children are subjected and responding appropriately to their suffering; and it serves to keep society dissociated from the impact violence has on us.     

Gender and Self-Reported Sexual Arousal in Response to Sexual Stimuli: A Meta-Analytic Review

Social constructionist theories and sociobiological perspectives have led to increased interest in gender differences in sexual behavior. This study involved a meta-analysis of gender differences in sexual arousal in response to sexual stimuli. Forty-six studies in which participants were presented with a sexual stimulus depicting males and females and in which participants responded using a self-report measure of arousal were compiled, and 62 independent effect sizes were aggregated. An overall effect size of d = .31 showed a small to moderate-sized gender difference in sexual arousal with men reporting more arousal than women across all studies. There was significant variation in the effect sizes, though, which was only partially explained by variables coded from the studies. It was found that the gender difference was slightly larger for studies using pornographic vs. erotic stimuli, was larger for studies where participants were tested in a private setting or small group compared to a large group, and was much larger for college age participants compared to those who were older than college age. Generally, the pattern of results provided more support for predictions from social influence theories compared to sociobiological theory.

SEQUENTIAL APPLICATION OF MAJOR HABIT-REVERSAL COMPONENTS TO TREAT MOTOR TICS IN CHILDREN

In this study, we sequentially administered up to four components of the habit-reversal treatment to 4 children with motor tics within a multiple baseline design. The habit-reversal components included (a) awareness training; (b) awareness training and self-monitoring; (c) awareness training, self-monitoring, and social support; and (d) awareness training, social support, and the use of a competing response. Results demonstrated that the combined use of awareness training, social support, and competing response training was effective in eliminating motor tics in 2 of 4 children, that awareness training alone was effective for 1 child, and that a combination of awareness training and self-monitoring was effective for the 4th child. The treatment and ensuing improvement were found to be socially valid. We discuss possible explanations for these results and recommend directions for future research.     

A Playroom Observation Procedure to Assess Children with Mental Retardation and ADHD

Forty-two children (ages 6 to 12 years old) with moderate mental retardation to borderline intellectual functioning were studied in a laboratory playroom setting to determine whether children identified as ADHD (attention deficit hyperactivity disorder) or controls differed on activity and attentional measures. Children with ADHD were further divided into ADHD + conduct problems (ADHD + CD) and ADHD-only subgroups (with an ADHD-combined group comprising children of both subgroups). An interval recording system was used to code observations of independent play and a restricted academic task. Results indicated that the ADHD-combined group was significantly more vocal and engaged in a significantly greater number of toy changes than controls during independent play. Significant group differences were also noted during the restricted academic task, with the ADHD-combined and ADHD + CD groups more off-task and engaging in a greater number of toy touches than controls. Discriminant analyses found independent play measures to predict group membership in 70 percent of cases (ADHD-combined vs. controls), but in only 64 percent of cases using measures from the restricted academic task. No significant findings resulted when the ADHD subjects were further divided into two subgroups. Despite some inconsistent findings, such laboratory-based observations may be of value in the diagnosis of ADHD in children with moderate mental retardation to borderline intellectual functioning.     

The Hairlessness Norm: The Removal of Body Hair in Women

This study aimed to investigate the frequency andmeaning of the removal of body hair in women.Participants were 129 female university students (meanage = 22.3 years) and 137 female high school students (mean age = 14.3 years). Almost all (>95%)were Caucasian. It was found that, as predicted, the vastmajority (92%) of women remove their leg and/or underarmhair, most frequently by shaving. This was irrespective of their feminist beliefs, but wasnegatively related to self-esteem in university students.The reasons cited for hair removal were primarilyconcerned with a desire for femininity andattractiveness. However, the reasons provided for starting toremove body hair differed between the groups, in thatthey were relatively more normative for the universitystudents than for the high school students. It was concluded that women's stated reasons forstarting the practice of hair removal reflectprimarilytheir vantage point as an observer. In fact, removingbody hair is a practice so normative as to go mostly unremarked, but one which contributessubstantially to the notion that womens' bodies areunacceptable as they are.     

SOCIAL REACTIONS, COPING STRATEGIES, AND SELF-BLAME ATTRIBUTIONS IN ADJUSTMENT TO SEXUAL ASSAULT

The present study investigated the impact of social reactions of others to sexual-assault victims on disclosure of their victimization. A convenience sample of adult sexual-assault victims (N = 155) completed a mail survey in which they reported information about their sexual assaults and postassault experiences. As expected, all negative social reactions were strongly associated with increased psychological symptoms, whereas most positive social reactions were unrelated to adjustment. The only social reactions related to better adjustment were being believed and being listened to by others. Victims experiencing negative social reactions also reported poorer adjustment even when other variables known to affect psychological recovery were controlled. Avoidance coping mediated the association of negative social reactions with adjustment. Implications of these findings for research and treatment of sexual-assault survivors are discussed.
