Intact emotion-induced recognition bias in neuropsychological patients with executive control deficits

In recognition memory tasks, emotionally negative words are judged more often as "old" relative to emotionally neutral words, suggesting a shift in response bias. We wondered whether this bias shift was due to the flexible regulation of executive control during memory retrieval. To address this question, we investigated individuals with high variability in executive control functions. As expected, we observed that emotional word meaning did indeed have a strong influence on the bias toward responding "old," independent of recognition accuracy and overall response bias. However, these effects were uncorrelated with executive control, as measured by the Trail Making Test, and were fully intact, even in a sample of hospitalized neurological patients with severe executive dysfunctions, some of whom had marked damage in fronto-thalamo-striatal networks. Having concluded that the emotion-induced bias must develop on different grounds, we went on to discuss alternative explanations.     

Applied Computer Diagnostics — Theoretical Foundations and Future Perspectives

The paper reviews and discusses a number of issues relating to the use of computer technology to assist the process of assessing psychologically relevant variables — computer-assisted diagnostics. A definition of computer-assisted diagnostics is given and theoretical developments are discussed. The paper emphasizes the need to consider theoretical issues relating to a number of domains: theory of content, test theory, human—computer interaction, programming theory, instructional theory, normative theory and situation theory. The paper concludes with a view of the current situation and future perspectives, and describes some important ethical issues.     

Motivational control of motor performance by goal setting in a dual-task situation

Summary The goal-setting approach to task motivation is applied to examine the way in which subjects control their performance on two concurrently performed tasks under the guidance of different goals in a dual-task situation. The tasks were a simple auditory-manual reaction time (RT) task and a visual-manual pursuit-tracking task. The goal conditions assigned alternatively to the tasks differed with respect to goal specificity and feedback information (KR) given after the trials. It is shown that the improvement of performance in the task with hard, specific goals is achieved in both cases at the cost of the concurrently performed other task which, on the basis of a lack of feedback and a rather unspecific goal instruction, should have a lower priority. The data reveal some strategies hidden behind these overall changes of the average performance at both tasks. For the RT task, the adjustment to the different goals is mainly achieved by changes in the temporal control or preparatory processes as can be inferred from the RT distributions as well as from the analysis of some typical errors. For the tracking task, changes in the tracking accuracy within the overlapping RT intervals are the best indicators for the performance control under the different goal conditions.This research was supported by a grant from the Deutsche Forschungsgemeinschaft (Kl 408/4-2)     

Psychological predictors for health-related quality of life and disability in persons with chronic obstructive pulmonary disease (COPD)

Objective: Individuals with chronic obstructive pulmonary disease (COPD) exhibit low physical and mental health-related quality of life (HRQL) and high susceptibility to disability. We investigated the influence of psychological factors on HRQL and disability in COPD individuals recruited from the general population. In line with Leventhal’s common sense model, we expected psychological factors to be associated with HRQL and disability even after controlling for medical status.

Methods: Individuals with COPD (n = 502; 59.7 years old; GOLD grades were I: 3%, II: 17%, III: 34%, IV: 46%) were assessed through an online survey administered via COPD patient organisations in Germany. Individuals filled in the Short Form Health Survey (SF-12), COPD Assessment Test, Patient Health Questionnaire (modules: GAD-2, PHQ-15, PHQ-9), Brief Illness Perception Questionnaire, a questionnaire that assesses causal illness attributions, and the internal illness-related locus of control scale of the ‘KKG questionnaire for the assessment of control beliefs about illness and health’. Multiple linear regressions were calculated.

Results: The investigated factors explained high variances (disability = 56%, physical HRQL = 28%, mental HRQL = 63%, p ≤ .001). Better mental health, more optimistic illness perceptions, attribution to psychological causes, and stronger internal locus of control were associated with lower disability and better HRQL. Comorbid somatic symptoms contributed to high disability and low quality of life.

Conclusion: Psychological factors, such as illness perception, attribution and internal locus of control, were associated with disability and HRQL. These factors should be considered when designing treatments for individuals with COPD, and adequate interventions should be provided to enhance illness understanding and self-management skills.     

Optimizing preoperative expectations in cardiac surgery patients is moderated by level of disability: the successful development of a brief psychological intervention

Patients’ expectations have shown to be a major psychological predictor of health outcome in cardiac surgery patients. However, it is unclear whether patients’ expectations can be optimized prior to surgery. This study evaluates the development of a brief psychological intervention focusing on the optimization of expectations and its effect on change in patients’ expectations prior to cardiac surgery. Ninety patients scheduled for coronary artery bypass graft were randomly assigned to (1) standard medical care, (2) additional expectation manipulation intervention (EMI), and (3) additional attention control group. Therapists’ fidelity to intervention manuals and patients satisfaction with the intervention were assessed for both active intervention conditions. Patients’ expectations about post-surgical disability, treatment control, personal control, and disease duration were assessed before and after the psychological intervention. Demographical, medical, and psychosocial characteristics and disability were assessed at baseline. Treatment fidelity and patient satisfaction was very high in both intervention conditions. Only patients receiving EMI developed higher personal control expectations and longer (more realistic) expectations of disease duration. The effect of intervention group on patients’ disability expectations and patients’ personal control expectations was moderated by patient’s level of disability. EMI patients with low to moderate disability developed positive expectations whereas patients with high disability did not. This study shows the successful development of a short psychological intervention that was able to modify patients’ expectations, especially in those with low to moderate disability. Given the robust association of expectations and surgery outcome, such an intervention might offer the opportunity to enhance patients’ health following cardiac surgery.     

The direct way may not be the best way: Children with ADHD and their understanding of self-presentation in social interactions

Knowledge and use of self-presentational tactics is an important social skill. We examined understanding of the function of three different self-presentational tactics (self-promotion, ingratiation and blasting) in 11 8–12-year-old boys with attention-deficit/hyperactivity disorder (ADHD) and 11 matched comparison children. Children were given six different self-presentation stories, two for each one of the three different tactics. After each story, they were asked to evaluate the effects of the self-presentational tactic used. Children with ADHD rated self-promotion and blasting as more positive and more effective—and ingratiation as less positive and less effective—than children in the control group. This implicates that children with ADHD prefer simple and direct self-presentational strategies (like self-promotion), and, therefore, may not as easily understand more subtle strategies (like ingratiation). They also seem to be more inclined to use negatively connoted strategies (like blasting). We suggest that this limited understanding of self-presentational strategies in children with ADHD may explain some of their problems in social interactions. Therefore, social skill interventions in children with ADHD should incorporate elements focusing on use and understanding of different self-presentational strategies.     

Der Arztbrief

The right of inspection in the hospital documents, the hospital discharge report for example, is often refused to patients in in-patient psychotherapeutic treatment (psychiatry, psychosomatic and psychotherapeutic medicine) with reference to the protection of the patients themselves, their doctors or relatives. Within a systemic therapy approach patients of an acute psychosomatic care unit in a hospital the patients could inspect the report of their hospital treatment including all ?objective” and ?subjective” data of their hospital stay. The conversation with patients and their relatives about this report and modifications of the details and addresses of the report in case of patients’ objections is considered as a psychotherapeutic tool (narrative of doctor and patient) in order to improve the transparency of the diagnostic and therapeutic process and the insights in the psychosomatic mechanisms of the patient’s disease. We discuss our organisation of cocreating the hospital discharge report and our experiences with this type of patient-doctor-communication.     

Reflective verbalization improves solutions—the effects of question‐based reflection in design problem solving

In this experimental study (N=60), the impact of question‐based reflective verbalization on the quality of a design solution was investigated. Participants first designed an everyday object (garden grill) using various design strategies and then either answered questions of a naive partner, where they had to verbally describe, explain, justify and evaluate their solution (experimental group), or were given a filler task (control group). After the intervention, participants continued their design. The improvement in the design quality was significantly larger for the experimental group than for the control group. Significantly more participants of the experimental group developed new principles and added new explanations of functions to their design, whereas in the control group only corrections were made. We suggest that the dialogue specific style of reflective verbalization in the experimental group is linked to a specific way of thinking which is important for solving complex problems.
