Comparing perceptual and preferential decision making

Perceptual and preferential decision making have been studied largely in isolation. Perceptual decisions are considered to be at a non–deliberative cognitive level and have an outside criterion that defines the quality of decisions. Preferential decisions are considered to be at a higher cognitive level and the quality of decisions depend on the decision maker’s subjective goals. Besides these crucial differences, both types of decisions also have in common that uncertain information about the choice situation has to be processed before a decision can be made. The present work aims to acknowledge the commonalities of both types of decision making to lay bare the crucial differences. For this aim we examine perceptual and preferential decisions with a novel choice paradigm that uses the identical stimulus material for both types of decisions. This paradigm allows us to model the decisions and response times of both types of decisions with the same sequential sampling model, the drift diffusion model. The results illustrate that the different incentive structure in both types of tasks changes people’s behavior so that they process information more efficiently and respond more cautiously in the perceptual as compared to the preferential task. These findings set out a perspective for further integration of perceptual and preferential decision making in a single ramework.     

A self-regulation-based intervention to increase physical activity in cancer patients

The study examined whether a behavior-change intervention focusing on self-regulatory strategies and emphasizing role model support increases physical activity (PA) among insufficiently active (not meeting PA guidelines of 150 min/week) cancer patients. Ambulatory cancer patients [N = 72; 54% female; M = 56 years, SD = 12.34; most with breast or colon cancer (34, 15%)] were enrolled in the MOTIVACTION-study, a 4-week intervention (1-hr counseling, followed by weekly phone calls), with pretest (T1), posttest (T2) and a 10-week follow-up (T3). Participants were randomized to either an exercise or to a stress management intervention (active control). The exercise intervention emphasized self-regulatory strategies (e.g. action- and coping planning and self-monitoring); patients were also encouraged to contact a physically active same-sex role model as a potential exercise partner. The active control condition consisted of coping and relaxation techniques. Sixty-seven patients remained in the study and completed the SQUASH assessment of PA and a measure of perceived stress. PA was validated by Actigraph accelerometry. At T2, 46% of the patients in the exercise group and 19% of stress management patients increased their activity levels to meet PA guidelines (>150 min/week; χ²(1) = 5.51, p = .019). At T3, participants in the exercise intervention maintained their exercise level (46%), but also 31% of the stress management patients met the guidelines. All patients reported reductions in perceived stress. Additional analyses comparing patients in the exercise group by role model contact (63% realized contact) revealed that those who had contact with their role model were significantly more likely to adhere to the recommended guidelines (T2:50%; T3:64%) compared to those who did not have contact with a role model (T2:39%; T3:15%), suggesting the potential of mobilizing role model support to facilitate PA. In sum, cancer patients may not only benefit from an exercise intervention emphasizing self-regulation, but also from stress management, regarding both reducing stress and increasing PA.     

Back to School in a New Country? The Educational Participation of Adult Immigrants in a Life-Course Perspective

While the education of the children of immigrants is a much-researched theme, we know very little about the participation of adult immigrants in education. And yet, lifelong learning is a common demand in highly industrialized societies. This article provides a first empirical analysis of adult immigrants’ educational participation in Germany. It uses the novel German National Educational Panel Study with unique retrospective life-course data. By adopting a life-course perspective, both transnational continuities in the life-course as well as the ruptures caused by migration are captured. The analysis investigates in what ways participation in education is embedded in immigrants’ transnational life-course. It can be shown that immigrants’ participation in formal and nonformal full-time education is common. Hypotheses predict a central influence of (1) pre-immigration activities and (2) of legal immigration gateways. Sequence and cluster analysis detect two education-related incorporation patterns: one is marked by a dominance of educational activities and the other by phases in education alternate with employment and unemployment. The results of multivariate models underline the predictive power of pre-immigration activity, i.e., transnational continuity in immigrants’ life courses. But we can also observe substantial disruption like the transnational transition from employment to education which can be the enforced response to nonrecognition or devaluation of foreign educational credentials. Institutional opportunities and dispositions linked to legal immigration gateways are even more powerful predictors of educational participation. Altogether, the article illustrates how the interaction of structural opportunities and individual agency plays out in the formation of different incorporation trajectories of adult immigrants.     

The impact of epistemological beliefs and cognitive ability on recall and critical evaluation of scientific information

Scientific research findings are frequently picked up by the mainstream media, but it is largely unclear which factors have an impact on laypeople’s processing of the presented scientific information. In this study, we investigated the influence of cognitive and metacognitive inter-individual differences on recall and on critical evaluation of new scientific information that was presented in a journalistic article. Sixty-three participants (80 % female; mean age 24.1 ± 3.3 years) read a newspaper article reporting research findings on a recently developed and yet unproven treatment for depression. We found that more sophisticated, domain-specific epistemological beliefs and a higher cognitive ability were independently associated with better recall of content from the article. Additionally, participants with more sophisticated epistemological beliefs displayed a more critical evaluation of the article. Cognitive ability was unrelated to critical evaluation and to epistemological beliefs. There were also no interaction effects of cognitive ability and epistemological beliefs on recall or on critical evaluation. Based on our preliminary findings and previous evidence of epistemological beliefs as a modifiable feature, we discuss this inter-individual characteristic as a potential target for the promotion of better understanding of scientific topics by the general public.     

Beitrag der Neurowissenschaften zur forensischen Psychiatrie

Forensic psychiatry is a subspecialty dedicated to the interface between psychiatry and law. It uses paradigms and knowledge from general psychiatry for diagnostics, assessment, therapy and research under consideration of the special requirements of legal aspects and framework conditions; therefore, scientific development in forensic psychiatry is substantially dependent on scientific progress in psychiatry and thus nowadays also in neurosciences. Neurobiological hypotheses on the neuronal foundations of psychiatric diseases have been established, for example the dopamine hypothesis for schizophrenia, in a manner that led to important therapeutic advances in the treatment and long-term quality of life for affected persons. Analogous advances should not be withheld from forensic psychiatric patients, who are doubly affected by the disease and the accompanying limitations in their rights to freedom, which is why research in this field must be driven forwards. Clear advances in knowledge of the neurobiological foundations of forensic psychiatric illnesses have, for example, already been made in the field of pedophilia and psychopathy. Based on studies of investigation populations, such neuroscientific knowledge on the neurobiological principles of forensic psychiatric diseases, however, requires a carefully concerted communication with respect to dissemination in the media as well as in the interpretation of individual cases, for example in court. This is of great importance in order to prevent simplifying misconceptions and to avoid a subsequent loss of trust in the scientific process. Therefore, training of the new generation of forensic psychiatrists in the understanding and communication of scientific methods of modern forensic psychiatric neuroscience is of great importance for the societal impact and further advancement of the discipline.

Managing Pandemics—Demands,Resources, and Effective Behaviors Within Crisis Management Teams

Pandemics, such as the COVID-19 crisis, are very complex emergencies that can neither be handled by individuals nor by any single municipality, organization or even country alone. Such situations require multidisciplinary crisis management teams (CMTs) at different administrative levels. However, most existing CMTs are trained for rather local and temporary emergencies but not for international and long-lasting crises. Moreover, CMT members in a pandemic face additional demands due to unknown characteristics of the disease and a highly volatile environment. To support and ensure the effectiveness of CMTs, we need to understand how CMT members can successfully cope with these multiple demands. Connecting teamwork research with the job demands and resources approach as starting framework, we conducted structured interviews and critical incident analyses with 144 members of various CMTs during the COVID-19 pandemic. Content analyses revealed both perceived demands as well as perceived resources in CMTs. Moreover, structuring work processes, open, precise and regular communication, and anticipatory, goal-oriented and fast problem solving were described as particularly effective behaviors in CMTs. We illustrate our findings in an integrated model and derive practical recommendations for the work and future training of CMTs.     

The Accuracy of Retrospective Recall of Childhood ADHD: Results from a Longitudinal Study

Attention-deficit/hyperactivity disorder (ADHD) is a childhood-onset condition that may continue into adulthood. When assessing adult patients, clinicians usually rely on retrospective reports of childhood symptoms to evaluate the age-of-onset criterion. Since inaccurate symptom recall may impede the diagnosis and treatment of ADHD, knowledge about the factors influencing retrospective reports is needed. This longitudinal study investigated (a) the accuracy of retrospective symptom ratings by adult participants with a childhood diagnosis of ADHD (self-ratings) and parents or significant others (proxy ratings), and (b) the influence of current ADHD symptom severity and ADHD-associated impairments on retrospective symptom ratings. Participants (N =?55) were members of the Cologne Adaptive Multimodal Treatment (CAMT) study who had been referred and treated for ADHD in childhood and were reassessed in adulthood (average age 27 years). Participants’ retrospective self-ratings were substantially lower than, and did not correlate with, parents’ ADHD symptom ratings provided at study entry, while retrospective symptom ratings provided by proxy respondents correlated moderately with parents’ childhood ratings. In addition, participants were more likely to underreport childhood symptoms (79%) and more frequently denied the presence of three or more childhood symptoms (17%) compared to proxy respondents (65% underreporting, 10% false-negative recall). Proxy respondents’ symptom recall was best predicted by childhood ADHD, while participants’ symptom recall was best predicted by current ADHD symptom severity. ADHD-associated impairments were not correlated with symptom recall after controlling for childhood ADHD. Together, these findings suggest a recall bias in adult patients and question the validity of retrospective reports, even in clinical samples.
