Sexuality and Exercise Motivations: Are Gay Men and Heterosexual Women Most Likely to be Motivated by Concern About Weight and Appearance?

This study was designed to investigate the relationship between sexuality and exercise motivations in 93 British bar staff. Participants who self-identified as heterosexual, gay, or lesbian completed the revised version of the Exercise Motivations Inventory and reported exercise frequency. Heterosexual men scored lower on appearance motives than did heterosexual women and gay men, higher on enjoyment motives than did gay men, and higher on competition motives than did women and gay men. Men were significantly less likely than women to be motivated by weight management. Heterosexual men also reported exercising significantly more frequently than the other three groups. Suggestions for targeted exercise promotion initiatives are discussed.     

Cone excitation ratios correlate with color discrimination performance in the horse (Equus caballus)

Six horses (Equus caballus) were trained to discriminate color from grays in a counterbalanced sequence in which lightness cues were irrelevant. Subsequently, the pretrained colors were presented in a different sequence. Two sets of novel colors paired with novel grays were also tested. Performance was just as good in these transfer tests. Once the horse had learned to select the chromatic from the achromatic stimulus, regardless of the specific color, they were immediately able to apply this rule to novel stimuli. In terms of the underlying visual mechanisms, the present study showed for the first time that the spectral sensitivity of horse cone photopigments, measured as cone excitation ratios, was correlated with color discrimination performance, measured as accuracy, repeated errors, and latency of approach.     

A randomized controlled trial of cognitive behavior therapy for borderline personality disorder: rationale for trial, method, and description of sample

This paper describes the rationale for a randomized controlled trial, comparing cognitive behavior therapy in addition to treatment as usual with treatment as usual alone, for borderline personality disorder. Previous pioneering randomized controlled trials of psychotherapies have suffered from methodological weaknesses and have not always been reported clearly to allow adequate evaluation of either the individual study or comparisons across studies to be undertaken. We report on the recruitment and randomization, design, and conduct of an ongoing randomized controlled trial of one hundred and six patients with borderline personality disorder. Primary and secondary hypotheses and their planned analyses are stated. The baseline characteristics of 106 patients meeting diagnostic criteria for borderline personality disorder are described.     

Predictors and outcomes of early motherhood in the Australian Longitudinal Study on Women's Health

Early motherhood is identified as a social problem, and having children at an early age is assumed to lead to psychological distress, welfare dependence and socioeconomic disadvantage. Analysis of responses from 9,689 young participants in the Australian Longitudinal Study on Women's Health was used to examine predictors and outcomes of early motherhood in Australia. Survey 1 (1996, aged 18 - 23) and Survey 2 (2000, aged 22 - 27), were used to categorize women as Childless, Existing Mothers (before Survey 1) and New Mothers (became mothers before Survey 2). Multivariate logistic regressions provided comparisons on sociodemographics, gynaecological variables, psychological wellbeing and health behaviours. Survey 1 data show that Existing Mothers experience socioeconomic disadvantages and unhealthy lifestyles. However, those who will go on to become mothers earlier than their peers already experience similar disadvantages. Further, the Survey 2 data show that, when these pre-existing disadvantages are controlled for, the additional deficits experienced by early mothers are relatively minor. Social disadvantage predisposes women to become mothers early, and to adopt unhealthy behaviours. However, young Australian women cope well with the challenges of early motherhood. In the longer term, unhealthy lifestyles and low education may lead to ill health and disadvantage, but early motherhood is not the initiator of this trajectory.     

Exploring the association between color-blind racial ideology and multicultural counseling competencies

The authors examined the association between color-blind racial ideology and self-reported multicultural counseling competencies in 130 applied psychology students and mental health workers. Results from 1 sample (n = 79) indicated that greater levels of color-blind racial ideology as measured by the Color-Blind Racial Attitudes Scale (Neville, Lilly, Duran, Lee, & Browne, 2000) were (1) related to lower self-reported multicultural counseling awareness and knowledge as measured by the Multicultural Counseling Knowledge and Awareness Scale (MCKAS; Ponterotto, Gretchen, Utsey, Rieger, & Austin, 2002) and (2) accounted for a significant amount of variance in MCKAS scores over and above that explained by self-reported multicultural training, social desirability, and participant race. Findings from another sample also provided empirical support for the link between higher color-blind racial ideology and lower multicultural case conceptualization ability (n = 51), after controlling for the influence of the number of multicultural course(s) taken. Implications of the findings and future directions are provided.     

Action relations, semantic relations, and familiarity of spatial position in Balint’s syndrome: Crossover effects on perceptual report and on localization

We contrasted effects of the action relationship between objects, relative to effects of semantic relation and familiarity of spatial location, in a patient with Balint’s syndrome. We found enhanced perceptual report of objects placed in the correct colocations for action in comparison with when the objects (1) were placed in incorrect locations for action (Experiment 1), (2) were associatively related (Experiment 2), or (3) fell in familiar locations but were not action related (Experiment 4). In contrast, the ability to localize the objects was affected by whether the objects were in familiar as opposed to unfamiliar locations with respect to one another. Action relations between objects facilitate joint attention to both objects but do not facilitate binding to location. Familiar spatial relations facilitate spatial binding, but do not cue joint attention to the stimuli. Effects of action relation on attention and localization can be dissociated from effects of semantic relationship and familiarity of spatial location on attention and localization.     

Computer-Presented Video Prompting for Teaching Microwave Oven Use to Three Adults with Developmental Disabilities

We evaluated the use of a video prompting procedure for teaching three adults with developmental disabilities to make popcorn using a microwave oven. Training, using a 10-step task analysis, was conducted in the kitchen of the participant’s vocational training program. During baseline, participants were instructed to make popcorn, but were given no further instructions or prompts. Video prompting consisted of first watching a video clip of a step being performed and then giving participants the opportunity to imitate that step. This prompting procedure was introduced in a delayed multiple-probe across subjects design. Following acquisition, video prompting was removed and maintenance in the absence of video prompting was assessed at 2, 6, and 10 weeks. Two of the three participants acquired the task when video prompting was introduced and performed at 80–100% correct during follow-up sessions. These data suggest that video prompting may be an effective instructional strategy for teaching daily living skills to adults with developmental disabilities.     

Worry and Pathological Worry in Patients with Psoriasis: Cross Sectional and Longitudinal Analyses of the Penn State Worry Questionnaire (PSWQ) in Four Samples of Patients

The purpose of the present study was to examine the psychometric properties of the Penn state Worry Questionnaire (PSWQ) in patients with psoriasis. A series of cross-sectional and longitudinal studies were undertaken to assess the reliability, stability and validity of the measure. Patients with psoriasis from four samples (consecutive attendees, anxious patients, depressed patients, and 6-month follow-up of consecutive attendees) completed the PSWQ and measures assessing related constructs of anxiety and depression (HADS) and coping (COPE). The clinical severity of patients psoriasis was also assessed by dermatologists using the Psoriasis Area and Severity Index (PASI). Exploratory factor analysis was undertaken and receiver operator characteristic (ROC) analyses were used to examine the clinical utility of the PSWQ cut-off score for normal and pathological worry. Exploratory factor analysis suggested that the PSWQ is essentially unidimensional in patients with psoriasis. Intraclass correlation demonstrated that, over a 6-month period, the reproducibility of the PSWQ total scale was good in patients with anxiety and moderate in patients with depression. ROC analysis suggested that the optimum cutoff differentiating pathological worry was > 60, which is commensurate with findings in adult mental health more generally. The PSWQ cutoff for pathological worry showed a lower specificity for depression than anxiety. The PSWQ is an appropriate measure of pathological worry in patients with psoriasis. The cutoff on the scale for pathological worry demonstrates appropriate conceptual overlap with subordinate distress categories of anxiety and depression.     

Systemic blockade of D2-like dopamine receptors facilitates extinction of conditioned fear in mice

Extinction of conditioned fear in animals is the explicit model of behavior therapy for human anxiety disorders, including panic disorder, obsessive-compulsive disorder, and post-traumatic stress disorder. Based on previous data indicating that fear extinction in rats is blocked by quinpirole, an agonist of dopamine D2 receptors, we hypothesized that blockade of D2 receptors might facilitate extinction in mice, while agonists should block extinction, as they do in rats. One day after fear conditioning mice with three pairings of a white noise conditional stimulus (CS) with moderate footshock, we injected the D2 antagonist, sulpiride, the D2 agonist, quinpirole, or vehicle, just before repeated CS presentations to generate extinction. We assayed fear by measuring behavioral freezing during extinction presentations and then drug-free during CS presentations 1 d later. We found that sulpiride injections before extinction training facilitated extinction memory 24 h later, while quinpirole partially blocked extinction memory compared with vehicle-injected controls. Notably, sulpiride treatment yielded significant extinction after spaced CS presentations, which yield no extinction at all in vehicle-treated mice. These findings suggest that dopamine D2-mediated signaling contributes physiological inhibition of extinction, and that D2 antagonists may be useful adjuncts to behavior therapy of human anxiety disorders.
