Gains v. losses,or context dependence generated by confusion?

Animal Cognition - Tversky and Kahneman introduced the term framing for the finding that people give different answers to the same question depending on the way it is posed. One form of framing...     

The use of heuristics in intuitive mathematical judgment

Anecdotal evidence points to the use of beauty as an indication of truth in mathematical problem solving. In the two experiments of the present study, we examined the use of heuristics and tested the assumption that participants use symmetry as a cue for correctness in an arithmetic verification task. We manipulated the symmetry of sets of dot pattern addition equations. Speeded decisions about the correctness of these equations led to higher endorsements for both correct and incorrect equations when the addend and sum dot patterns were symmetrical. Therefore, this effect is not due to the fact that symmetry facilitates calculation or estimation. We found systematic evidence for the use of heuristics in solving mathematical tasks, and we discuss how these findings relate to a processing-fluency account of intuition in mathematical judgment.     

Das Absetzen antiandrogener Medikation im ambulanten Setting

In the Forensic Therapeutic Outpatient department in Berlin a total of n?=?20 individually justified, therapeutically accompanied withdrawals from antiandrogenic treatment have been implemented. The sample was compared with n?=?20 patients under antiandrogenic treatment. Patients with withdrawal have been significantly older, than patients without withdrawal. No differences were found regarding their duration of further imprisonment and standardized risk-assessment (HCR-20, LSI-R, Static-99, Stable-2007, PCL-R). Firsts results of the monitoring of the withdrawals indicate, that the symptom-checklist SCL-90-R is not appropriate for that purpose. However, post-hoc both known sexual reoffendings could be identified by the Massachusetts General Hospital Sexual Functioning Questionnaire. By means of practical experience results are getting discussed.     

Reality monitoring and metacognitive beliefs related to cognitive confidence in obsessive-compulsive disorder

The present study investigated general reality monitoring ability, and selective reality monitoring ability for anxiety relevant actions in a group of individuals with obsessive-compulsive disorder (OCD) and a group of non-anxious controls. In addition, reality monitoring confidence was assessed, as well as specific meta-cognitive beliefs related to cognitive confidence (by means of the Meta-Cognitions Questionnaire (MCQ)). No differences were found between both groups in actual reality monitoring ability. Unlike previous studies, the reality monitoring task included actions that were related to the individual concerns of the OCD patients and were ideographically selected. Nevertheless, no differential reality monitoring effect was observed for the anxiety relevant stimuli. Data from the MCQ, however, revealed that OCD patients had less overall confidence in their memory for actions and their reality monitoring ability. Analysis of the confidence ratings of the reality monitoring task showed that this reduced confidence was restricted to the neutral actions. No differences were observed for patients that reported low or high frequencies of checking behaviour. The whole of these data do not support memory deficit models of OCD, but are in line with recent emphasis on the importance of memory confidence and other meta-cognitive beliefs in OCD.     

Touch and Go: Merely Grasping a Product Facilitates Brand Perception and Choice

Consumers often touch products, and such haptic exploration can improve consumers' evaluations of the product. We tested whether cross‐modal priming might contribute to this effect. Under the guise of a weight judgment task, which served as a haptic prime, we had blindfolded participants grasp familiar products (e.g., a Coca Cola bottle). We then had participants visually identify the brand name as quickly as possible (Experiments 1 and 2), list the first beverage brands that come to mind (Experiment 3), or choose between beverage brands as reward for participation (Experiment 4). Haptic exposure facilitated visual recognition of the given brand and increased participants' consideration and choice of that brand. Moreover, this haptic priming was brand specific and occurred even among participants who did not consciously identify the prime brand. These results demonstrate that haptic brand identities can facilitate recognition, consideration, and brand choice, regardless of consumers' conscious awareness of this haptic priming.

Common Etiological Sources of Anxiety,Depression, and Somatic Complaints in Adolescents: A Multiple Rater twin Study

Somatic complaints in children and adolescents may be considered part of a broader spectrum of internalizing disorders that include anxiety and depression. Previous research on the topic has focused mainly on the relationship between anxiety and depression without investigating how common somatic symptoms relate to an underlying factor and its etiology. Based on the classical twin design with monozygotic and dizygotic twins reared together, our study aimed to explore the extent to which the covariation between three phenotypes in adolescent girls and boys can be represented by a latent internalizing factor, with a focus on both common and specific etiological sources. A population-based sample of twins aged 12–18 years and their mothers and fathers (N?=?1394 families) responded to questionnaire items measuring the three phenotypes. Informants’ ratings were collapsed using full information maximum likelihood estimated factor scores. Multivariate genetic analyses were conducted to examine the etiological structure of concurrent symptoms. The best fitting model was an ACE common pathway model without sex limitation and with one substantially heritable (44 %) latent factor shared by the phenotypes. Concurrent symptoms also resulted from shared (25 %) and non-shared (31 %) environments. The factor loaded most on depression symptoms and least on somatic complaints. Trait-specific influences explained 44 % of depression variance, 59 % of anxiety variance, and 65 % of somatic variance. Our results suggest the presence of a general internalizing factor along which somatic complaints and mental distress can be modeled. However, specific influences make the symptom types distinguishable.     

Das Restless-Legs-Syndrom

In 1995, the International Restless Legs Syndrome Study Group (IRLSSG) developed the first consensus-based diagnostic criteria, which were revised in 2003. These criteria allowed the implementation of numerous epidemiological, pathophysiological, and therapeutic approval studies. To increase the specificity, the guidelines were augmented regarding differential diagnoses, clinical severity, and objective examination in 2012. RLS, one of the most common neurological diseases worldwide, is often misdiagnosed and greatly underdiagnosed. Symptomatic treatment with dopaminergic agents is standard treatment for primary RLS; however, opioids are also used.     

The social image of drinking – mass media campaigns may inadvertently increase binge drinking

Mass media campaigns that promote responsible drinking are rarely tested for their usefulness in reducing heavy alcohol consumption. Existing campaigns that appeal to responsible drinking while simultaneously displaying young people in social drinking situations may even have paradoxical effects. To examine such possible effects, we drew on a real-world media campaign, which we systematically modified on the basis of recent prototype research. We pilot tested questionnaires (using n = 41 participants), developed two different sets of posters in the style of an existing campaign (n = 39) and investigated their effectiveness (n = 102). In the main study, young men were randomly assigned to one of three conditions: sociable or unsociable binge drinker prototype condition or a control group. Outcome variables were intention, behavioural willingness, attitude, subjective norm, self-efficacy, prototype evaluation and prototype similarity with respect to binge drinking. Binge drinking as a habit was included to control for the fact that habitual drinking in social situations is hard to overcome and poses a particular challenge to interventions. The manipulation check showed that the experimental variation (sociable vs. unsociable drinker prototype condition) was successful. Results of the main study showed that the sociable drinker prototype condition resulted in a higher willingness and – for those with less of a habit – a higher intention to binge drink the next weekend. The unsociable drinker prototype condition had no effects. The results imply that the social components of mass media campaigns might inadvertently exacerbate binge drinking in young men. We therefore advocate against campaigns including aspects of alcohol consumption that might be positively associated with drinker prototype perception. Finally, we provide suggestions for future research.
