Genetic architecture of context processing in late middle age: more than one underlying mechanism

Studies comparing young and older adults suggest a deficit in processing context information as a key mechanism underlying cognitive aging. However, the genetic architecture of context processing has not been examined. Consistent with previous results, we found evidence of functionally dissociable components of context processing accuracy in 1127 late middle-aged twins ages 51-60. One component emphasizes use of context cues to prepare responses (proactive cognitive control), and the other emphasizes adjustment of responses after probes are presented (reactive control). Approximately one-quarter of the variance in each component was accounted for by genes. Multivariate twin analysis indicated that genetic factors underlying two important components of context processing were independent of one another, thus implicating more than one underlying mechanism. Slower reaction time (RT) on noncontext processing trials was positively correlated with errors on the strongly proactive control component on which young adults outperform older adults, but RT was negatively correlated with errors on the strongly reactive control component on which older adults perform better. Although this RT measure was uncorrelated with chronological age in our age-homogeneous sample, slower RT was associated with performance patterns that were more like older adults. However, this did not generalize to other processing speed measures. Genetic correlations, which reflect shared genetic variance, paralleled the phenotypic correlations. There was also a positive genetic correlation between general cognitive ability and accuracy on the proactive control component, but there were still mostly distinct genetic influences underlying these measures. In contrast, the reactive control component was unrelated to general cognitive ability.     

Investigating Hegemonic Masculinity: Portrayals of Masculinity in Men’s Lifestyle Magazines

A content analysis of eight different men’s lifestyle magazines sold in Canada between November 2004 and August 2006 was conducted to explore how masculinities are currently being portrayed in regards to the body, aesthetics and grooming, and fashion. Findings suggest that different men’s magazines represent different forms of masculinity but elements of hegemonic masculinity (culturally normative ideals of masculinity within a structure of social relations where some men are subordinated) are woven throughout. Although the marketed look varies by the magazine, these magazines not only convey the message that appearance can be manipulated—but it should also be enhanced, and that men should engage in bodywork in order to attain the lifestyle they desire.     

The Impact of Anger Management Treatment and Rational Emotive Behavior Therapy in a Public School Setting on Social Skills,Anger Management,and Depression

Public school students participated in a group to enhance and improve anger management. The study used a pre-post design with a comparison group. Students were assigned to either Anger Management Treatment or Anger Management plus Rational Emotive Behavior Therapy (REBT). Each child served as his or her own control and received an empirically validated intervention. Pretest–posttest data were evaluated using the Social Skills Rating System, the Children’s Depression Inventory and the Children’s Inventory of Anger. Results indicate that the addition of the REBT component to Anger Management reduced anger as well as depression, while improving social skills, suggesting the addition of a specialized cognitive behavioral component increased the effectiveness of the intervention.     

The processing of auditory and visual recognition of self-stimuli

This study examined self-recognition processing in both the auditory and visual modalities by determining how comparable hearing a recording of one’s own voice was to seeing photograph of one’s own face. We also investigated whether the simultaneous presentation of auditory and visual self-stimuli would either facilitate or inhibit self-identification. Ninety-one participants completed reaction-time tasks of self-recognition when presented with their own faces, own voices, and combinations of the two. Reaction time and errors made when responding with both the right and left hand were recorded to determine if there were lateralization effects on these tasks. Our findings showed that visual self-recognition for facial photographs appears to be superior to auditory self-recognition for voice recordings. Furthermore, a combined presentation of one’s own face and voice appeared to inhibit rather than facilitate self-recognition and there was a left-hand advantage for reaction time on the combined-presentation tasks.     

The Effects of Incentives on Visual–Spatial Working Memory in Children with Attention-deficit/Hyperactivity Disorder

Working memory is one of several putative core neurocognitive processes in attention-deficit/hyperactivity disorder (ADHD). The present work seeks to determine whether visual–spatial working memory is sensitive to motivational incentives, a laboratory analogue of behavioral treatment. Participants were 21 children (ages 7–10) with a diagnosis of ADHD-combined type. Participants completed a computerized spatial span task designed to assess storage of visual–spatial information (forward span) and manipulation of the stored information (backward span). The spatial span task was completed twice on the same day, once with a performance-based incentive (trial-wise feedback and points redeemable for prizes) and once without incentives. Participants performed significantly better on the backward span when rewarded for correct responses, compared to the no incentive condition. However, incentives had no effect on performance during the forward span. These findings may suggest the use of motivational incentives improved manipulation, but not storage, of visual–spatial information among children with ADHD. Possible explanations for the differential incentive effects are discussed, including the possibility that incentives prevented a vigilance decrement as task difficulty and time on task increased.     

“Not a little Mickey Mouse thing”: How experienced counselling psychologists describe the significance of personal therapy in clinical practice and training. Some results from an interpretative phenomenological analysis

The British Psychological Society's Division of Counselling Psychology currently specifies a mandatory period of personal therapy for trainees. However, evidence for the role of personal therapy in developing practitioner competence is sparse. This paper presents part of a wider ongoing interpretative phenomenological analysis exploring how counselling psychologists describe the meaning and significance of personal therapy in clinical practice and training. Detailed examination of a subset of data from this study suggests that personal therapy is valued as a vehicle for a genuine, often extremely intense relationship with the therapist, through which participants become able to establish authentic emotional contact with themselves and their clients. Whilst most participants felt that personal therapy should remain an obligatory part of the training curriculum, they were ambivalent about specifying its aims or evaluating its outcomes. Results are discussed in terms of the importance of establishing a sense of integrity and authenticity within the personal therapy experience and are tentatively situated within a possible theoretical framework drawing on current developmental literature.     

Classroom observations of students with and without ADHD: Differences across types of engagement

The current study examined the behaviors related to academic engagement exhibited by students with ADHD during instruction in math and reading. A total of 155 students (92 ADHD, 63 recruited controls) in grades 1 through 4 participated in the study. Results revealed that students with ADHD exhibited statistically significant lower rates of academic engagement and higher rates of off-task behaviors than recruited controls and randomly selected peer comparisons. Specifically, students with ADHD exhibited statistically significant lower rates of passive academic engagement (PET) than recruited controls and peer comparisons; however no group differences were found with regard to active engaged time (AET). In addition, students with ADHD exhibited lower rates of AET than PET, a finding observed among both recruited controls and randomly selected peer comparisons. Implications for research and practice are discussed.
