An Uncontrolled Examination of a 5-Day Intensive Treatment for Pediatric OCD

This study examined the feasibility of a 5-day intensive treatment for pediatric obsessive-compulsive disorder (OCD). Fifteen children with OCD received a week-long treatment based on exposure and response prevention (ERP). The intervention also emphasized teaching children and parents how to conduct ERP independently at home. All families completed the week-long treatment and symptoms improved significantly as measured by self- and parent-report forms, as well as the Children's Yale-Brown Obsessive-Compulsive Scale, F(2, 22) = 45.67, p < .05. Total CY-BOCS scores decreased significantly from pretreatment (M = 28.00, SD = 4.24) to posttreatment [M = 16.00, SD = 6.0, F(1, 11) = 34.38, p < .05] and from posttreatment to 5-month follow-up [M = 11.5, SD = 7.3; F(1, 11) = 12.94, p < .05]. This level of improvement was consistent with other intensive treatments for pediatric OCD. The study suggests that the 5-day program is a promising treatment for children with OCD who do not have access to local providers.     

Involvement of shared resources in time judgment and sequence reasoning tasks

Previous research suggests that time perception is supported by the same attentional resources involved in sequence processing. The present experiment was designed to clarify this connection by examining the relation between timing and reasoning tasks that involved either sequencing or non-sequencing judgments. For the timing task, subjects produced a series of 5-s intervals. For the reasoning tasks, subjects judged whether pairs of statements describing common actions either (a) were presented in the correct temporal order (sequencing), or (b) described similar actions or objects (similarity). Subjects performed the timing and reasoning tasks both separately and concurrently in a series of 3-minute trials. Comparisons of single-task and dual-task performance assessed interference patterns between concurrent tasks. Both reasoning tasks interfered with timing by making temporal productions longer and more variable. Timing had differential effects on the two reasoning tasks. Concurrent timing caused sequencing judgments to become slower, less accurate, and less sensitive relative to sequencing-only conditions. In contrast, similarity judgments were either unaffected or affected to a lesser degree by the concurrent timing task. These results support the notion that timing and sequencing are closely related processes that rely on the same set of cognitive resources or mechanisms.     

Traditionality and the Discriminating Effect of Expectations of Occupational Success and Occupational Values for Women within Math-Oriented Fields

Success expectations and vocational values have been identified as important features of women's career pursuits. Also, examination of differences among women pursuing traditionally and nontraditionally open fields has proven illuminating. Nonetheless, the women compared in such studies often pursued fields requiring vastly different competencies, interests, and training. This study investigated possible differences between women majoring in math-oriented fields in a traditionally closed area, engineering, and those in a traditionally open area, math education, with respect to success expectations in such fields and to the importance of various vocational outcomes. Success expectations for traditional and nontraditional occupations distinguished between the two groups, as did values for a number of vocational outcomes. In understanding women's career choices, the findings support the role of success expectations, the little studied role of outcome desirability, and the value of examining within-group occupational orientations within fields differing in traditionality but requiring similar skills, training, and interests.     

Gender and Video Game Performance

We investigated potential gender differences in video game (pong) performance in university students. In Experiment 1 men (N = 16) performed significantly better than women (N = 16). Experiment 2 was similar to the first, but used 14 men and 14 women who were matched carefully on previous video game experience. In spite of the matching, results replicated those of the first experiment. In Experiment 3 we evaluated the effect of an audience (male, female, none) on pong performance in 42 men and 42 women. We also assessed trait competition anxiety (Sport Competition Anxiety Test scores), sex role identification (Bem Sex Role Inventory scores), and video game experience. Both genders showed significantly poorer performance when they played pong in the presence of a female audience. Overall, males outperformed females as in the first two experiments. Examination of individuals with low, medium, and high levels of sport competition anxiety and videogame experience reveals persistent gender differences in performance, seemingly independent of levels of anxiety and experience. In all three experiments, both men and women showed significant improvement in performance over trials.     

How Are Different Properties of a Scene Encoded in Visual Memory?

Recent studies in scene perception suggest that much of what observers believe they see is not retained in visual memory. Depending on the roles they play in organizing the perception of a scene, different visual properties may require different amounts of attention to be incorporated into a mental representation of the scene. The goal of this study was to compare how three visual properties of scenes, colour, object position, and object presence, are encoded in visual memory. We used a variation on the change detection “flicker” task and measured the time to detect scene changes when: (1) a cue was provided regarding the type of change; and, (2) no cue was provided. We hypothesized that cueing would enhance the processing of visual properties that require more attention to be encoded into scene representations, whereas cueing would not have an effect for properties that are readily or automatically encoded in visual memory. In Experiment 1, we found that there was a cueing advantage for colour changes, but not for position or presence changes. In Experiment 2, we found the same cueing effect regardless of whether the colour change altered the configuration of the scene or not. These results are consistent with the idea that properties that typically help determine the configuration of the scene, for example, position and presence, are better encoded in scene representations than are surface properties such as colour.     

On Vandervert et al. “Working Memory,Cerebellum, and Creativity”

Four measures of self-determination (SD) were correlated with two measures of trait creativity. In Study 1, subjects high on the Creative Personality Scale (Gough, 1979) and the Problem-Solving/Creativity scale (Marsh &; O'Neill, 1984) were found to strive for self-determined reasons, to strive toward greater SD, and to evidence higher SD in measures of both motivational orientation and self-concept. Study 2 replicated most of these findings and also showed that creative subjects perceived their parents to be more autonomy supportive. Results are interpreted in terms of a general disposition to be self-determining that may help attune creative people to deeper cognitive resources and capacities within themselves.     

Sad Kids,Sad Media? Applying Mood Management Theory to Depressed Adolescents' Use of Media

Mood management studies typically have found that adults will select media that enhance positive moods and reduce negative moods. In this study, adolescents diagnosed with major depressive disorder and control adolescents without psychiatric disorders were called on customized cell phones up to 4 times a day and asked about their current mood state and media use for five extended weekends across an 8-week period. Mood effects on subsequent media use, mood during media consumption, and media effects on subsequent mood were examined. Results indicated that adolescents who consumed fun media tended to do so in a way that sustained, rather than enhanced their prior positive mood levels during and after consumption-if they turned to media. Adolescents in more negative moods did not often use media to improve their moods. When they did, boys were more likely than girls to use media that ultimately reduced negative mood levels. Findings are discussed in light of the literature on mood management, adolescence, and depression.     

Social inclusion facilitates risky mating behavior in men

Although past research has reliably established unique effects of social exclusion on human cognition and behavior, the current research focuses on the unique effects of social inclusion. Recent evidence indicates that social inclusion leads to enhanced prioritization of reproductive interests. The current study extends these findings by showing that the pursuit of these inclusion-induced reproductive goals occurs in sex-specific ways. Across three experiments, social inclusion led men, but not women, to endorse riskier, more aggressive mating strategies compared to control and socially excluded participants. Specifically, included men were more likely to endorse sexual aggression (Experiment 1), high-risk mate poaching behaviors (Experiment 2), and high-risk mate retention tactics (Experiment 3). These results demonstrate that the experience of social inclusion can affect sex-differentiated preferences for risky mating strategies.     

Response to hyperventilation and inhalation of 5.5% carbon dioxide-enriched air across the DSM-III-R anxiety disorders.

Anxiety disorder patients (n = 198; under criteria of the Diagnostic and Statistical Manual of Mental Disorders; rev. 3rd ed.; American Psychiatric Association, 1987) and nonanxious control subjects (n = 25) underwent challenges of 90 s of voluntary hyperventilation and 15 min of 5.5% carbon dioxide in air. Panic disorder subjects showed a greater subjective response to both challenges than did subjects with other anxiety disorders, who in turn responded more than did control subjects. Furthermore, subjects with panic disorder as an additional diagnosis tended to report more subjective response than did anxiety disorder subjects without panic disorder. The best prechallenge predictor of response to each procedure was a measure of fear of physical symptoms. The findings support previous results that have pointed to a greater fear or anxiety-inducing effect of these challenge procedures in panic disorder patients, as compared with other subjects.
