Neural Recruitment and CognitiveAging: Two Hemispheres Are Better Than One, Especially as You Age

Several neuroimaging studies have reported that older adults show weaker activations in some brain areas together with stronger activations in other areas, compared with younger adults performing the same task. This pattern may reflect neural recruitment that compensates for age-related neural declines. The recruitment hypothesis was tested in a visual laterality study that investigated age differences in the efficiency of bihemispheric processing. Letter-matching tasks of varying complexity were performed under two conditions: (a) matching letters projected to the same visual field (hemisphere) and (b) matching letters projected to opposite visual fields (hemispheres). As predicted by the recruitment hypothesis, older adults generally performed better in the bilateral than unilateral condition, whereas younger adults showed this pattern onlyfor the most complex task. We discuss the relation between these results and neuroimaging evidence for recruitment, and the relevance of the present bihemispheric advantage to other evidence for age-related changes in interhemispheric transfer.     

A grouping interpretation of the modality effect in immediate probed recognition

In a series of experiments on immediate probed recognition for eight 3-digit numbers, it was shown that if the target modality involved auditory components and the effect of the similarity of the modality of the probe to that of the targets was controlled, unequivocal evidence was obtained for an auditory superiority effect (modality effect) for hit rates for the final items of the list. Moreover, false-alarm rates were significantly lower following targets with an auditory component than they were following silently seen targets. It is argued that this pattern of hits and false alarms is consistent with the idea that targets that have an auditory component yield memory representations that are better grouped as units than are those for targets that are only silently seen; in particular, if a new probe has a first digit that accidentally matches the first digit of a target item, it is more likely that the subject will mistakenly identify this new probe as old (give a false alarm) if the target has only been partially encoded because it was only silently seen.     

Examining the Experience of Undergoing Group Cognitive Behavioral Therapy for Obsessive Compulsive Disorder: An Interpretative Phenomenological Analysis

This study used interpretative phenomenological analysis (IPA) to explore the lived experiences of five individuals diagnosed with obsessive-compulsive disorder (OCD) who underwent a group cognitive behavioral therapy (CBT) intervention program to address their symptoms. Two master themes were identified: experiences and processes of change and reflections on change. For all participants, the degree of group cohesion or connectedness they established with group members emerged as highly important in facilitating therapeutic progress. A number of technical elements of cognitive behavioral therapy (CBT) were also notable therapeutic factors, including questioning/rationalizing maladaptive interpretations about intrusions. However, the commonality of non-specific group processes as key features for subsequent therapeutic change prompts the need for further research in dynamics within CBT group interventions for OCD.     

Dimensional Personality Traits Broadly and Selectively Associated with Normative Externalizing Behavior

This study aimed to distinguish personality traits that are widely associated with several types of externalizing behaviors from personality traits that are more selectively associated with one or only a few specific types of externalizing behavior. A wide range of externalizing behaviors (e.g. alcohol and drug use, risky driving, aggressive acts, sexual promiscuity and relationship infidelity, academic misconduct) typical among an undergraduate population (N?=?257) were examined along with a range of personality traits measured using the Section III personality model for the DSM-5. We found that externalizing behavior was best associated with the domain level trait Antagonism and, to a lesser degree, Disinhibition. Antagonism’s association with problematic behavior was primarily accounted for by the facet trait Deceitfulness. Deceitfulness was found to be associated with a wide range of behaviors including relationship infidelity, theft, aggressive acts, and drug and alcohol use. Associations between Disinhibition and problem behavior, especially risky driving and poor work or school performance, were best accounted for by the Irresponsibility facet, as opposed to the Impulsivity or Distractibility facet traits. This comprehensive multivariate approach is important for a more complete understanding of the complex relationship that exists between personality traits and externalizing behavior. A better understanding of factors precipitating externalizing behavior could ultimately lead to an increased ability to target interventions to individuals most susceptible to engage in problematic behavior.     

Executive Functioning Correlates of <Emphasis Type="Italic">DSM-5</Emphasis> Maladaptive Personality Traits: Initial Evidence from an Italian Sample of Consecutively Admitted Adult Outpatients

In order to evaluate the associations between computer-administered tasks of executive functioning (EF), and maladaptive personality domains and traits listed in DSM-5 Alternative Model of Personality Disorders, 53 consecutively admitted psychotherapy outpatients (female participants: n?=?27, 50.9%; male participants: n?=?26, 49.1%; participants’ mean age?=?37.28 years, SD?=?11.50 years) were administered the Psychology Experiment Building Language (PEBL) EF tasks and the Personality Inventory for DSM-5 (PID-5). According to rank-order correlation analyses, a number of non-negligible and specific associations were observed between selected PID-5 scales and indices of participants’ performance on EF tasks. MM robust regression models showed that participants’ performance on computer-administered EF tasks explained a non-negligible amount of variance in selected PID-5 scale scores (median R² value?=?.17). As a whole, our trait-level analyses of PID-5 dimensions suggest the clinical usefulness of integrating self-reports and EF laboratory tasks in routine clinical assessment.     

Treatment Outcome of 18-Month, Day Hospital Mentalization-Based Treatment (MBT) in Patients with Severe Borderline Personality Disorder in the Netherlands

Psychoanalytically oriented day hospital therapy, later manualized and named mentalization-based treatment (MBT), has proven to be a (cost-) effective treatment for patients with severe borderline personality disorder and a high degree of psychiatric comorbidity (BPD) in the United Kingdom (UK). As to yet it has not been shown whether manualized day hospital MBT would yield similar results when conducted by an independent institute outside the UK. We investigated the applicability and treatment outcome of 18-month, manualized day hospital MBT in the Netherlands by means of a prospective cohort study with 45 Dutch patients with severe BPD and a high degree of comorbid Axis I and Axis II disorders. Outcomes were assessed each six months. Symptom distress, social and interpersonal functioning, and personality pathology and functioning all improved significantly, with effect sizes between 0.7 and 1.7. Suicide attempts, acts of self-harm, and care consumption were also significantly reduced. The results indicate that MBT can effectively be implemented in an independent treatment institute outside the UK. This study also supports the clinical effectiveness of manualized day hospital MBT in patients with severe BPD and a high degree of psychiatric comorbidity.     

Getting the big picture: Development of spatial scaling abilities

Spatial scaling is an integral aspect of many spatial tasks that involve symbol-to-referent correspondences (e.g., map reading, drawing). In this study, we asked 3–6-year-olds and adults to locate objects in a two-dimensional spatial layout using information from a second spatial representation (map). We examined how scaling factor and reference features, such as the shape of the layout or the presence of landmarks, affect performance. Results showed that spatial scaling on this simple task undergoes considerable development, especially between 3 and 5 years of age. Furthermore, the youngest children showed large individual variability and profited from landmark information. Accuracy differed between scaled and un-scaled items, but not between items using different scaling factors (1:2 vs. 1:4), suggesting that participants encoded relative rather than absolute distances.     

Multisystemic therapy for young offenders: families' experiences of therapeutic processes and outcomes

Multisystemic Therapy (MST) has been found to be effective in reducing youth antisocial behavior, but little is known about the process and impact of MST from the perspective of families themselves. This qualitative study explored parents' and young people's experiences of MST, focusing on aspects of the intervention that promoted or limited change. Thirty-seven semistructured interviews were conducted with a consecutive sample of 21 families (21 parent interviews, 16 young people) who had participated in a randomized controlled trial of MST for young offenders in the United Kingdom. Thematic analysis yielded 10 themes, organized into two domains: (a) engagement in MST and initial processes of change captures the central importance of the therapeutic relationship and the MST engagement model in families' positive experiences of MST; and (b) outcomes are complex reflects the range of positive outcomes reported (notably increased parental confidence and skills, improved family relationships, a return to education, and greater reflection and aspiration on the part of the young person) and mixed behavior outcomes. Even when the young person had reoffended, respondents indicated a range of other benefits for the family. The findings support the MST theory of change as well as point to some outcomes not usually measured in MST outcome studies. They also suggest some adaptations that may increase the impact of the intervention, including more attention to the influence of deviant peers, and ongoing support for families struggling to maintain strategies beyond the prescribed treatment period.
