Risk Taking and Sensitivity to Punishment in Children with ADHD,ODD, ADHD+ODD,and Controls

We used the Balloon Analog Risk Task (BART) to examine risk taking and sensitivity to punishment, two relevant aspects of behavioral inhibition, in 203 school-age children with attention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), ADHD+ODD, and controls. Participants earned points on the BART by pumping 30 separate balloons that exploded at variable intervals. No points were earned on a trial when a balloon exploded. The number of pumps across all balloons estimated risk taking and the reduction in pumps following balloon explosions was interpreted as an indicator of sensitivity to negative punishment. We found that all groups significantly differed from one another on risk taking. The ADHD+ODD group pumped the most, followed by the ODD, ADHD, and the control group, respectively. For sensitivity to negative punishment, all groups performed differently, with the ODD group showing the least sensitivity to an exploded balloon, followed by the ADHD, control, and ADHD+ODD groups, respectively. Children with ADHD+ODD demonstrated significantly different patterns of risk taking and sensitivity to negative punishment than children with either ADHD-only or ODD-only. ADHD youth with comorbid ODD had the greatest levels of risk taking, but they were also the most sensitive to negative punishment. The relationship between ADHD and ODD, as well as the nature of comorbidity in constructs related to risk taking and related behaviors, are discussed.     

Einzel- und Paarintervention f��r depressive Koronarpatienten

Depressive symptoms in patients presenting with coronary heart disease have an impact on quality of life, health behavior, and prognosis. The psychotherapeutic interventions which had been tested for their efficacy in previous randomized controlled trials, showed only minor effects. A stepwise approach consisting of individual and group psychotherapeutic interventions was tested for efficacy in a German multicenter study. The presented paper describes the therapeutic procedure for two individual sessions and one couple session by means of case examples. The main focus was to determine depressive symptoms along with underlying maladaptive personality traits such as negative affectivity and social inhibition (type D pattern). Depressive mood, disappointments and mortifications both in private and professional life and also during the previous treatment are verbalized. Dysfunctional relation patterns and maladaptive sickness behavior are taken up by the psychotherapist and alternative behavior patterns are developed. The objective of the couple session is strengthening the partnership resources and offering relief of fears and worries relative to the heart disease. The psychotherapeutic procedure is psychodynamically oriented but also contains cognitive-behavioral and interactional treatment approaches.     

When the brain decides: a familiarity-based approach to the recognition heuristic as evidenced by event-related brain potentials

Humans can make fast and highly efficient decisions by using simple heuristics that are assumed to exploit basic cognitive functions. In the study reported here, we used event-related potentials (ERPs) to disclose the psychological mechanisms underlying one of the most frugal decision rules, namely, the recognition heuristic. According to this heuristic, whenever two objects have to be ranked by a specific criterion and only one object is recognized, the recognized object is ranked higher than the unrecognized object. Using a standard recognition-heuristic paradigm, we predicted participants' decisions by analyzing an ERP correlate of familiarity-based recognition occurring 300 to 450 ms after stimulus onset. The measure remained a significant predictor even when later ERP correlates were taken into account. These findings are evidence for the thesis that simple heuristics exploit basic cognitive processes. Specifically, the findings show that familiarity--that is, recognition in the absence of recollection--contributes to decisions made on the basis of such heuristics.     

Internetbasierte Vorbereitung auf eine station?re psychosomatisch-psychotherapeutische Behandlung

Background

Encouraged by promising results of online aftercare programs, this study adapted the concept of internet-based minimal interventions in order to use the time between referral and actual admission to inpatient treatment. The online intervention includes information about the hospital and the treatment and sections which aim to enhance motivation, provide support and allow contact.

Methods

A comprehensive cohort study was conducted with 379 participants in the randomized subcohort. Primary endpoint was the speed of change of the physical, mental and social impairment and of the psychological well-being in the first 2 weeks of inpatient treatment as well as the rates of reliable change 2 weeks after admission.

Results

Both the control and intervention group of the randomized subcohort showed statistically significant improvements in health status. No significant difference in the rate of change was found. The degree of achieved improvement in the physical impairment was equal to the expected intervention effect. A difference in the rates of change was found for the psychological well-being: the intervention group showed 19% more reliable improvements.

Conclusions

The study design and the contents of the intervention were accepted by the patients. The internet-based intervention can help to prepare for treatment and to shorten the settling-in period.     

Category priming with aliens: analysing the influence of targets' prototypicality on the centre surround inhibition mechanism

Marginally perceptible prototypes as primes lead to slowed reactions to related category exemplars as compared to unrelated ones. This at first glance counterintuitive finding has been interpreted as evidence for a particular mechanism of lateral inhibition, namely the centre surround inhibition mechanism. We investigated the semantic surround of category labels by experimentally manipulating the prototypicality of stimuli. Participants first learned two new categories of fantasy creatures in a 5-day-long learning phase before they worked through a semantic priming task with the category prototypes as primes and category exemplars as targets. For high-prototypical targets we observed benefit effects from related primes, whereas for low-prototypical targets we observed cost effects. The results define when the centre surround inhibition mechanism is applied, and furthermore might explain why previous studies with word stimuli (i.e., material that prevents experimental manipulation of prototypicality) observed mixed results concerning the prototypicality of targets.     

Discriminant validity and interaction between perceived organizational support and perceptions of organizational politics: A temporal analysis

We used two‐wave panel data based on a sample of 137 employees from a small Korean manufacturing company to examine first the discriminant validity of, and then the interaction between perceived organizational support (POS) and perceptions of organizational politics (POP). We focused on the relationships between POS, POP, and three employee work‐related outcomes, affective organizational commitment, intention to stay, and individually oriented organizational citizenship behaviour (OCBI). Confirmatory factor analysis revealed that POS and POP were distinct constructs. Moreover, time‐lagged LISREL estimates showed that POS and POP were differentially related to the three outcomes in a theoretically predictable way. POP did not moderate the relationship between POS and either affective commitment or intention to stay. POS, however, significantly moderated the POP–OCBI relationship. The implications of the results for POS and POP theory and research are discussed.     

On the positive aspects of customers: Customer‐initiated support and affective crossover in employee–customer dyads

This study examines psychological resources for service employees and their customers, which enhance the service experiences of both parties during service conversations. We investigate whether customer behaviour (customer‐initiated support) positively impacts on employees’ affect. We also examine the crossover of employees’ affect on customers’ affect. State positive affect (PA) was assessed in 82 employees of car dealerships and 421 customers on 2 occasions (before and after the conversation). Multi‐level analyses showed the hypothesized positive impact of customer behaviour on employees’ PA and in turn of employees’ PA on customers’ PA. Results are integrated in an overall process model whereby customers’ PA leads to customer‐initiated support, which increases employees’ PA and in turn enhances customers’ PA. Results suggest direct and indirect crossover effects. This study extends research on customer behaviour offering a positive slant on customer behaviour and suggests to actively involve customers in the service process in order to promote their positive behaviour towards employees.

Poems and commentary from the perspective of a nurse, an emergency medical technician and two physicians are accompanied by an exploration of the meaning of work and the role of medical humanities.     

What Does Diffusion Tensor Imaging Reveal About the Brain and Cognition in Fetal Alcohol Spectrum Disorders?

Over the past 5 years, Diffusion Tensor Imaging (DTI) has begun to provide new evidence about the effects of prenatal alcohol exposure on white matter development. DTI, which examines microstructural tissue integrity, is sensitive to more subtle white matter abnormalities than traditional volumetric MRI methods. Thus far, the available DTI data suggest that white matter microstructural abnormalities fall on a continuum of severity in Fetal Alcohol Spectrum Disorder (FASD). Abnormalities are prominent in the corpus callosum, but also evident in major anterior-posterior fiber bundles, corticospinal tracts, and cerebellum. These subtle abnormalities are correlated with neurocognitive deficits, especially in processing speed, non-verbal ability, and executive functioning. Future studies using larger samples, increasingly sophisticated DTI methods, and additional functional MRI connectivity measures will better characterize the full range of abnormalities in FASD. Ultimately, these measures may serve as indices of change in future longitudinal studies and in studies of interventions for FASD.     

The Contributions of Child Behavioral Functioning and Parent Distress to Family Functioning in Pediatric Inflammatory Bowel Disease

The objective of this study was to examine the relative contributions of both parental and adolescent functioning to family functioning in adolescent patients with inflammatory bowel disease (IBD) and their families. Participants were 45 adolescents (27 male, 18 female) 13-17?years old (M?=?15.41?years, SD?=?1.32) with IBD and their parents. Families completed measures of patient behavioral functioning and depression, parent distress and family functioning. Disease severity assessments were completed via data provided by patients' gastroenterologists. Results indicated that parent-reported patient behavioral problems accounted for a significant 26% of variance in family functioning. Post-hoc analysis revealed that externalizing behavior problems accounted for the majority of this variance compared to internalizing behavior problems. These results suggest that externalizing problems may have a more significant impact on these families than previous research indicates. Moreover, externalizing behaviors may significantly impact family adaptation and should be taken into consideration during routine clinical care. Further research is needed to replicate and expand upon these findings.
