Alexithymia, Cumulative Feedback, and Differential Response Patterns on the Iowa Gambling Task

ABSTRACT Although the role of emotional processing is central to contemporary models of risky decision making, to date the role of trait emotional understanding has not been explored experimentally in this context. The current experiment ( N =326) explores the role of alexithymia with respect to performance on the standard Iowa Gambling Task (IGT) and a version where cumulative financial feedback is obscured. Standard learning on the IGT was observed for those low in alexithymia. Those high in alexithymia learned to avoid disadvantageous decks over the first half of the task. However, over the later trials they showed a change in performance, shifting from advantageous to disadvantageous and back to advantageous decks again (termed an "explore-learn-change-return" strategy). It is argued that this is due to an inability to fully consolidate earlier learning and reduced sensitivity to losses. The absence of cumulative feedback independently resulted in reduced performance.     

Individual Differences in Training Gains and Transfer Measures: An Investigation of Training Curves in Children with Attention‐Deficit/Hyperactivity Disorder

Currently, evidence for the beneficial effects of working memory (WM) training on transfer measures in children with attention‐deficit/hyperactivity disorder (ADHD) is inconsistent. Although there is accumulating evidence for the role of individual differences in training and transfer gains of cognitive training, this area has been left unexplored for children with ADHD. In the current study, an advanced latent growth curve model analysis was used to investigate the individual differences in learning curves (training gains) of WM training tasks within a new cognitive intervention ‘Paying Attention in Class’. It was investigated whether certain baseline variables (age, intelligence quotient, externalizing behaviour problems and presence of learning disability) predicted the learning curves and how these individual learning curves influenced near‐transfer and far‐transfer measures. A total of 164 children diagnosed with ADHD, between the age of 8 and 12 years old, followed this new Paying Attention in Class intervention. WM (near‐transfer) and academic performance (far‐transfer) measures were assessed before treatment and directly after treatment. Results showed that individual differences at the start of training were predicted by age and intelligence quotient, but the individual differences in learning curves were not predicted by any of the baseline variables. Both for the verbal and the visuospatial WM training, children with larger training gains (i.e. steeper training curves) showed larger benefits on the near untrained transfer measures. These effects were absent for the far‐transfer measures. Current study shows that training WM is quite complex and has its limitations for children with ADHD. Nonetheless, it highlights that training and transfer gains are affected by many different factors and warrants the need of a more in‐depth investigation of individual differences in future studies.Copyright © 2017 John Wiley & Sons, Ltd.     

Resilience in Holocaust Survivors: A Study of Defense Mechanisms in Holocaust Narratives

There is extensive literature examining the psychological adaptation of survivors after the Holocaust, including studies of Holocaust narratives (HN). As a measure of psychological adaptation, defense mechanisms (DM) have been studied in various clinical samples, however, to date, not in Holocaust narratives. Using a standardized observer-rated measure, we assessed DM in Holocaust versus pre/post Holocaust narratives (other narratives [ON]) in 20 in-depth survivor interviews. Regarding individual DM, isolation of affect and self-assertion were statistically more frequent in the HN than the ON. High adaptive (mature) level defenses were more frequent in the HNs than the ON. Furthermore, the overall defensive functioning (ODF) was higher in the HN than the ON, contradicting previous findings showing lower defensive functioning in life-threatening situations. Possible explanations include differences in the nature of trauma, the time elapsed between the trauma and the interview, and the specificity of the sample. A qualitative overview with several examples from the narratives are also presented.     

Which behaviours? Identifying the most common and burdensome behaviour changes in amyotrophic lateral sclerosis

Behaviour change is increasingly recognised as a common feature of amyotrophic lateral sclerosis (ALS), and may be similar to that seen in frontotemporal dementia (FTD). The behaviours most disturbed in ALS, and those that relate most significantly to caregiver burden, however, have not been well established. Forty ALS participants and their caregivers, and 27 age- and gender-matched healthy controls and their relatives, participated in this study. ALS participants were assessed on a disease rating scale, and caregivers and control informants completed the revised version of the Cambridge Behaviour Inventory and a measure of burden. ALS caregivers reported significantly more disturbance than healthy control informants on the functional domains of everyday skills, self-care, and sleep, and in the behavioural domains of mood and motivation. There were no differences between groups in frequency of memory and orientation difficulties, or behaviours characteristic of FTD, such as changes to eating habits or stereotypic and motor behaviour, indicating that the behavioural profile in ALS may differ from FTD. In the ALS group, the domains with the strongest relationship to caregiver burden were everyday skills, motivation and memory, likely because poor motivation, memory dysfunction and difficulties completing activities of daily living require more carer support via direct supervision, prompting or hands on care. Services to support ALS patients and caregivers need to provide targeted interventions for those functional and behavioural changes which are most burdensome in the disease.     

Understanding the genetic and environmental specificity and overlap between well‐being and internalizing symptoms in adolescence

Moderate inverse correlations are typically found between well‐being and mental illness. We aimed to investigate the role of genes and environments in explaining the relationships between two aspects of well‐being and two measures of internalizing symptoms. Altogether, 4700 pairs of 16‐year‐old twins contributed data on subjective happiness and life satisfaction, as well as symptoms of depression and emotional problems. Well‐being was moderately correlated with internalizing symptoms (range = ?0.45, ?0.58). Multivariate twin model‐fitting indicated both genetic and environmental overlap. Life satisfaction and happiness demonstrated different patterns of overlap, with stronger genetic links between life satisfaction and depression. Non‐shared environmental influences were largely specific to each trait. This study supports the theory of mental health and illness being partly (but not entirely) correlated dimensions. There are also significant genetic and environmental factors to identify for well‐being that go beyond the absence of mental illness. It is therefore possible that different interventions are needed for treating mental illness and promoting mental health.     

Hot and Cool Executive Function and its Relation to Theory of Mind in Children with and without Autism Spectrum Disorder

Previous research has clearly demonstrated that autism spectrum disorder (ASD) involves deficits in multiple neuropsychological functions, such as executive function (EF) and theory of mind (ToM). A conceptual distinction is commonly made between cool and hot EF. In ASD, continued attention has been paid to the cool areas of executive dysfunction. Cool EF has been strongly related to ToM, but research has not taken into account the association between hot EF and ToM in ASD. The present study investigated the associations between hot and cool EF and ToM in 56 school-aged children with ASD and 69 controls on tasks tapping cool EF (i.e., working memory, inhibition, planning), hot EF (i.e., affective decision making, delay discounting), and ToM (i.e., mental state/emotion recognition and false belief). Significant group differences in each EF measure support an executive dysfunction in both domains in ASD. Strong associations between delay discounting and ToM mental state/emotion recognition were found, suggesting that hot EF makes a unique contribution to ToM above and beyond cool EF in typical development and ASD. This study improves understanding of the profile of higher-order cognitive deficits in children with ASD, which may inform diagnosis and intervention.     

Human Energy Expenditure and Postural Coordination on the Mechanical Horse

The authors investigated and compared the energy expenditure and postural coordination of two groups of healthy subjects on a mechanical horse at 4 increasing oscillation frequencies. Energy expenditure was assessed from the oxygen consumption, respiratory quotient, and heart rate values, and postural coordination was characterized by relative phase computations between subjects (elbow, head, trunk) and horse. The results showed that the postural coordination of the riders was better adapted (i.e., maintenance of in-phase and antiphase) than that of the nonriders, but the energy expenditure remains the same. Likewise, we observed an energy system shifting only for nonriders (from aerobic to lactic anaerobic mode). Finally, cross-correlations showed a link between energy expenditure and postural coordination in the riders (i.e., effectiveness).     

Matthews Model of Clinical Reasoning: A Systematic Approach to Conceptualize Evaluation and Intervention

Clinical reasoning is a complex process required for effective therapeutic encounters. Its development is poorly understood. The clinical reasoning process is placed in a historical context based on the occupational therapy literature. An emerging model of clinical reasoning is proposed. This model of clinical reasoning provides a unique perspective in order to compartmentalize the person, environment, and occupation constructs around the person’s life story, connect it directly to the occupational therapy practice framework, and determine treatment priorities, emphasizing a client-centered perspective. A client-centered model of clinical reasoning supports efforts to provide effective intervention.     

How prisoners and their partners experience the maintenance of their relationship during a prison sentence

Research shows that intimate relationships, and their maintenance via prison visits, have a positive impact on factors associated with prisoner well‐being and reduced likelihood of recidivism. It is therefore in the interest of corrections, government, and wider society to enable prisoners to maintain healthy relationships with their family and intimate partners throughout their prison sentence. Despite this evidence, little is known about how prisoners experience the maintenance of a significant intimate relationship in prison. This study aims to explore heterosexual couples' experiences in maintaining their well‐established intimate relationships, while the male partner is incarcerated. Four main themes were identified: how they experienced “having a special connection” that they were motivated to maintain; “coping with challenges and threats” to that connection; “developing reciprocal behaviours” to meet those challenges; and “maintaining a belief in the future.” Implications for how the relational context of rehabilitation can best be supported is considered.     

Increased number of responses may account for reduced resurgence following serial training

Abrupt discontinuation of functional communication training can cause resurgence of challenging behavior. Teaching multiple alternative responses in sequence (serial training) may reduce resurgence, relative to teaching a single alternative. However, previous evaluations of serial training included a different number of response options across comparison conditions. In Experiment 1, we varied both training type (single and serial) and number of response options, and replicated previous findings showing that more resurgence occurred following single training relative to serial training. In Experiment 2, we varied the training type while holding the number of alternative responses constant and obtained no consistent differences in resurgence. In Experiment 3, we varied the number of alternative responses while holding training type constant (i.e., single). More resurgence occurred in the condition with fewer response options, suggesting that the number of available alternative responses, and not explicit serial training of alternatives, was critical to outcomes.
