Does Time Fly When You are Having Fun? A Day Reconstruction Method Analysis

Duration-based measures of happiness from retrospectively constructed daily diaries are gaining in popularity in population-based studies of the hedonic experience. Yet experimental evidence suggests that perceptions of duration—how long an event lasts—are influenced by individuals’ emotional experiences during the event. An important remaining question is whether observational measures of duration outside the laboratory setting, where the events under study are engaged in voluntarily, may be similarly affected, and if so, for which emotions are duration biases a potential concern. This study assesses how duration and emotions co-vary using retrospective, 24-h diaries from a national sample of older couples. Data are from the Disability and Use of Time supplement to the nationally representative U.S. Panel Study of Income Dynamics. We find that experienced wellbeing (positive, negative emotion) and activity duration are inversely associated. Specific positive emotions (happy, calm) are not associated with duration, but all measures of negative wellbeing considered here (frustrated, worried, sad, tired, and pain) have positive correlations (ranging from 0.04 to 0.08; p < .05). However, only frustration remains correlated with duration after controlling for respondent, activity and day-related characteristics (0.06, p < .01). The correlation translates into a potentially upward biased estimate of duration of up to 10 min (20 %) for very frustrating activities. We conclude that estimates of time spent feeling happy yesterday generated from diary data are unlikely to be biased but more research is needed on the link between duration estimation and feelings of frustration.     

Uncertainty is associated with increased selective attention and sustained stimulus processing

Uncertainty about future threat has been found to be associated with an overestimation of threat probability and is hypothesized to elicit additional allocation of attention. We used event-related potentials to examine uncertainty-related dynamics in attentional allocation, exploiting brain potentials’ high temporal resolution and sensitivity to attention. Thirty participants performed a picture-viewing task in which cues indicated the subsequent picture valence. A certain-neutral and a certain-aversive cue accurately predicted subsequent picture valence, whereas an uncertain cue did not. Participants overestimated the effective frequency of aversive pictures following the uncertain cue, both during and after the task, signifying expectancy and covariation biases, and they tended to express lower subjective valences for aversive pictures presented after the uncertain cue. Pictures elicited increased P2 and LPP amplitudes when their valence could not be predicted from the cue. For the LPP, this effect was more pronounced in response to neutral pictures. Uncertainty appears to enhance the engagement of early phasic and sustained attention for uncertainly cued targets. Thus, defensive motivation related to uncertainty about future threat elicits specific attentional dynamics implicating prioritization at various processing stages, especially for nonthreatening stimuli that tend to violate expectations.     

Entwicklung und Stand des psychiatrischen Maßregelvollzugs (§ 63 StGB)

Psychiatric forensic commitment is at the interface between psychiatry and criminal justice. Both fields are subject to societal and political influences, which are not to be underestimated and have undergone many changes since the introduction of the catalogue of penal measures in 1933. This article provides a summarizing overview of the development of psychiatric penal measures in the 8 decades since its inception. The various developmental phases are chonologically presented and analyzed, in some cases with reference to the international situation. The main transition is the change from custodial detention up to modern treatment enforcement, even if many different factors influence the certainly to be strived for further development. Finally, the complex topics of “forensic psychiatry and the public” as well as the influence of the media on this aspect are briefly discussed.     

Working memory training: improving intelligence--changing brain activity

The main objectives of the study were: to investigate whether training on working memory (WM) could improve fluid intelligence, and to investigate the effects WM training had on neuroelectric (electroencephalography - EEG) and hemodynamic (near-infrared spectroscopy - NIRS) patterns of brain activity. In a parallel group experimental design, respondents of the working memory group after 30 h of training significantly increased performance on all tests of fluid intelligence. By contrast, respondents of the active control group (participating in a 30-h communication training course) showed no improvements in performance. The influence of WM training on patterns of neuroelectric brain activity was most pronounced in the theta and alpha bands. Theta and lower-1 alpha band synchronization was accompanied by increased lower-2 and upper alpha desynchronization. The hemodynamic patterns of brain activity after the training changed from higher right hemispheric activation to a balanced activity of both frontal areas. The neuroelectric as well as hemodynamic patterns of brain activity suggest that the training influenced WM maintenance functions as well as processes directed by the central executive. The changes in upper alpha band desynchronization could further indicate that processes related to long term memory were also influenced.     

White-matter microstructure and language lateralization in left-handers: A whole-brain MRI analysis

Most people are left-hemisphere dominant for language. However the neuroanatomy of language lateralization is not fully understood. By combining functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI), we studied whether language lateralization is associated with cerebral white-matter (WM) microstructure. Sixteen healthy, left-handed women aged 20–25 were included in the study. Left-handers were targeted in order to increase the chances of involving subjects with atypical language lateralization. Language lateralization was determined by fMRI using a verbal fluency paradigm. Tract-based spatial statistics analysis of DTI data was applied to test for WM microstructural correlates of language lateralization across the whole brain. Fractional anisotropy and mean diffusivity were used as indicators of WM microstructural organization. Right-hemispheric language dominance was associated with reduced microstructural integrity of the left superior longitudinal fasciculus and left-sided parietal lobe WM. In left-handed women, reduced integrity of the left-sided language related tracts may be closely linked to the development of right hemispheric language dominance. Our results may offer new insights into language lateralization and structure–function relationships in human language system.     

Illegitimate tasks as assessed by incumbents and supervisors: converging only modestly but predicting strain as assessed by incumbents,supervisors, and partners

ABSTRACT

Illegitimate tasks are tasks that violate norms about what an employee can reasonably be expected to do. Representing a relatively recent stressor concept, illegitimate tasks have been linked to strain, but so far have been assessed only by self-report. The current multisource study investigates to what extent supervisors’ assessments of illegitimate tasks converge with incumbents’ self-reports of illegitimate tasks and predict three kinds of strain, namely psychological strain (incumbent report of exhaustion), behavioural strain (supervisors report of incivility), and family strain (partner report of work-family conflict). Low convergence between assessments was expected due to idiosyncratic appraisals but also to differing perspectives of supervisors and incumbents due to their roles, as described by the newly developed roles-as-perspectives theory proposed in this paper. Data from 166 triads were analysed by structural equation modelling and Relative Weight Analysis. Results showed that convergence between incumbent and supervisor reports of illegitimate tasks was rather low; it was higher when the supervisor had a limited span of control. Illegitimate tasks were associated with all three types of strain for both self- and supervisor reports of illegitimate tasks, indicating that the detrimental effects of illegitimate tasks cannot be explained by common method biases alone and that incumbents and supervisors have overlapping but not identical concepts of illegitimate tasks.     

Recognition memory for emotional faces in amnestic mild cognitive impairment: An event-related potential study

ABSTRACT

This study examined the temporal course of emotional face recognition in amnestic mild cognitive impairment (aMCI). Patients and healthy controls (HC) performed a face recognition task, giving old/new responses to previously studied and novel faces displaying a negative or neutral expression. In aMCI patients, recognition accuracy was preserved for negative faces. Event-related potentials (ERPs) revealed disease-related changes in early perceptual components but not in ERP indices of explicit recognition. Specifically, aMCI patients showed impaired recognition effects for negative faces on the amplitudes of N170 and P2, suggesting deficient memory-related processing of negative faces at the stage of structural encoding and during an early recognition stage at which faces are individuated, respectively. Moreover, while a right-lateralized emotion effect specifically observed for correctly recognized faces on the amplitude of N170 was absent in aMCI, a similar emotion effect for successfully recognized faces on P2 was preserved in the patients, albeit with a different distribution. This suggests that in aMCI facilitated processing of successfully recognized emotional faces starts later in the processing sequence. Nonetheless, an early frontal old/new effect confined to negative faces and a parietal old/new effect unaffected by facial emotion were observed in both groups. This indicates that familiarity and conceptual priming processes may specifically contribute to recognition of negative faces in older adults and that aMCI patients can recruit the same retrieval mechanisms as controls, despite disease-related changes on early perceptual ERP components.     

Affect in analogical transfer

Abstract:

The putative importance of analogy in creative insight and intelligence has been repeatedly supported in anecdotal reports of creative scientists and theoretical proposals on creativity. The aim of the present study was to investigate the influence of affect on analogical transfer. For that purpose, three experiments were conducted in which negative, neutral, or positive affect was induced by films. Persons were asked to solve ill‐defined, well‐defined, and insight problems. Analogical reasoning was evoked by base information presented prior to the film and target problem. The first two experiments indicated that positive affect facilitates transfer in ill‐defined problems, but impairs it in well‐defined problems. These findings are discussed in terms of the cognitive strategies used to solve well‐ and ill‐defined problems, and the theoretical assumptions about the impact of positive affect on cognitive organization. The results of the third experiment supported the hypothesis that the influence of positive affect on analogical transfer is related to the form (visual/verbal) of presenting the base analogy.
