Psychometric properties of the Revised Male Body Attitudes Scale among Irish men

The psychometric properties of a revised version of the Male Body Attitudes Scale (Tylka, Bergeron, & Schwartz, 2005) were investigated using two independent online samples of Irish men (ns=241 and 253, respectively). Exploratory factor analyses suggested that a 15-item, 3-factor solution representing men's attitudes toward their body fat, muscularity, and height best described the data. The internal consistency and construct validity of scores on the Revised Male Body Attitudes Scale suggest that this measure holds promise as an indicant of men's attitudes toward their physical appearance. Limitations and strengths associated with the current research are discussed and directions for future research are outlined.     

The what–where trade-off in multiple-identity tracking

Observers are poor at reporting the identities of objects that they have successfully tracked (Pylyshyn, Visual Cognition, 11, 801-822, 2004; Scholl & Pylyshyn, Cognitive Psychology, 38, 259-290, 1999). Consequently, it has been claimed that objects are tracked in a manner that does not encode their identities (Pylyshyn, 2004). Here, we present evidence that disputes this claim. In a series of experiments, we show that attempting to track the identities of objects can decrease an observer's ability to track the objects' locations. This indicates that the mechanisms that track, respectively, the locations and identities of objects draw upon a common resource. Furthermore, we show that this common resource can be voluntarily distributed between the two mechanisms. This is clear evidence that the location- and identity-tracking mechanisms are not entirely dissociable.     

Stimulus range and discontinuity effects on information-integration category learning and generalization

Two studies are reported that support the hypothesis that categories that require a multiple-unit, as opposed to a single-unit, representation lead to worse initial acquisition but better generalization. On the basis of the constraints imposed by the procedural-based learning system thought to mediate information-integration categorization, we argue that the need to train multiple units during initial category acquisition slows the procedural-based category learning process and adversely affects learning performance. However, we speculate that better generalization occurs because of the increased likelihood that a novel stimulus will activate at least one of the multiple units needed to represent the category. Relations to other findings in the literature and the implications of this work for training and clinical assessment are discussed.     

Risk factors for disordered eating during early and middle adolescence: prospective evidence from mainland Chinese boys and girls

Despite evidence that sociocultural and psychological factors contribute to disordered eating, researchers have yet to examine the extent to which putative risk factors influence vulnerability for girls versus boys within and across phases of adolescence, particularly in non-Western cultures. In this study, early and middle adolescent samples from China (N = 2,909) completed measures of eating disorder pathology and putative risk factors at baseline and were reassessed 12 months later. Among both younger and older girls, elevations in appearance-focused interactions with friends, negative affect, and body dissatisfaction predicted increases in symptomatology at follow-up. In contrast, there was more discontinuity in risk factors relevant to samples of boys. Although media and friendship influences contributed to later disturbances among early adolescent boys, psychological factors, including body dissatisfaction and negative affect, had stronger effects in the multivariate model for older boys. Implications of finding are discussed in relation to adolescent development and a Chinese cultural context.     

Surprise-induced blindness: a stimulus-driven attentional limit to conscious perception

The cost of attending to a visual event can be the failure to consciously detect other events. This processing limitation is well illustrated by the attentional blink paradigm, in which searching for and attending to a target presented in a rapid serial visual presentation stream of distractors can impair one's ability to detect a second target presented soon thereafter. The attentional blink critically depends on 'top-down' attentional settings, for it does not occur if participants are asked to ignore the first target. Here we show that 'bottom-up' attention can also lead to a profound but ephemeral deficit in conscious perception: Presentation of a novel, unexpected, and task-irrelevant stimulus virtually abolishes conscious detection of a target presented within half a second after the 'Surprise' stimulus, but only for its earliest occurrences (generally 1 to 2 presentations). This powerful but short-lived deficit contrasts with a milder but more enduring form of attentional capture that accompanies singleton presentations in rapid serial visual presentations. We conclude that the capture of stimulus-driven attention alone can limit explicit perception.     

Effects of Numbered Heads Together on the Daily Quiz Scores and On-Task Behavior of Students with Disabilities

Previous research has demonstrated that Numbered Heads Together, a cooperative learning strategy, is more effective than traditional teacher-led instruction in academic areas such as social studies and science. The current study compared the effects of two types of Numbered Heads Together strategies with a baseline condition during 7th grade language arts lessons. Results indicated that three students with various disabilities had higher percent intervals of on-task behavior and daily quiz scores during either Heads Together condition. Teacher satisfaction ratings suggested that Heads Together was easy to implement, and all three students preferred this strategy to baseline instruction. A discussion of study limitations, implications, and future research directions is included.     

A Clinical Model in Action in Intensive Residential Treatment: Meeting the Needs of Adolescent Boys who have Experienced Domestic Violence

The Habitat Program at Wood’s Homes, Calgary, Alberta, is an eight bed residential treatment program for conduct-disordered youth who have been exposed or subjected to high levels of violence in their family home. The program was based on the assumption that working effectively with such youth requires consideration of the background experiences of family violence, yet traditional treatment models often ignore or minimize the importance of these experiences. We present a clinical model which incorporates aspects of milieu treatment, relationship-based daily interventions and elements of Jenkins’ invitational approach to working with men and boys who use violence as well as Wade’s response-based approach to counseling with victims and perpetrators of violence. The model also incorporates ideas based on Maruna’s research into recidivism and excuse-making. The purpose of the model is twofold: to be broad enough to structure an overall treatment strategy based on the assumption that successful treatment results from the cumulative effect of many interactions over time, and to be specific enough to guide staff in developing strategies for specific situations that typically arise in daily interaction with the youth. We use a case example format to illustrate how staff has utilized the model to engage youth in exploring both their experiences of violence in the family home and in developing new ways of thinking and talking about behavioural choices.     

Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders: Protocol Development and Initial Outcome Data

The Unified Protocol (UP) is a transdiagnostic, emotion-focused cognitive-behavioral treatment developed to be applicable across the emotional disorders. The UP consists of 4 core modules: increasing emotional awareness, facilitating flexibility in appraisals, identifying and preventing behavioral and emotional avoidance, and situational and interoceptive exposure to emotion cues. Here we present data from 2 open clinical trials. In the first trial, an initial version of the UP was administered to a heterogeneous clinical sample, yielding significant pre- to posttreatment effects across disorders on a variety of measures. Analyses of clinical significance demonstrated modest results, with 56% of participants achieving responder status and 33% achieving high end-state functioning. Further manual development ensued, resulting in specific modifications and enhancements to core treatment components, and a second trial presents data from an additional pilot study of this revised version of the UP. Results from this trial demonstrated more robust treatment effects, with 73% achieving responder status and 60% achieving high end-state functioning. Results improved further at 6-month follow-up, with 85% classified as treatment responders and 69% achieving high end-state functioning. Implications for the treatment of emotional disorders as well as dimensional conceptualizations of psychopathology are discussed.
