The role of Funktionswandel in metamorphopsia

Patients with metamorphopsia perceive objects or faces as being distorted and/or different in size. In most cases, recognition is not impaired. The stimulus specificity, particularly in the case of face perception, has led to the suggestion that metamorphopsia is a deficit at the entry level of category‐specific recognition systems; in this case, the face processing system. An explanation in terms of a visuosensory deficit (i.e. Funktionswandel) that affects the perception of specific stimulus categories has not been systematically evaluated. In this study, we report two patients (MZ and CM) who experienced hemi‐metamorphopsia for faces after a stroke in the posterior part of the brain. Despite the distortions, they could still match and recognize faces. We carried out a detailed evaluation of their visual‐sensory status and found that both MZ and CM had specific problems with discriminating and estimating sizes and shapes, especially in the contralesional visual field. It was concluded that these cases, metamorphopsia was not due to a higher‐order perception impairment specific for faces, but rather of a specific impairment in shape perception in the contralesional visual field that proportionally affects the perception of faces.     

Regional brain electrical activity in posttraumatic stress disorder after motor vehicle accident

This study examined whether patients with posttraumatic stress disorder (PTSD) related to motor vehicle accidents (MVAs) would show an abnormal pattern of electroencephalographic (EEG) alpha asymmetries, which has been proposed for particular types of anxiety. Patients with PTSD (n = 22) or subsyndromal PTSD (n = 21), traumatized controls without PTSD (non-PTSD with MVA; n = 21), and healthy controls without MVA (n = 23) underwent measurement of EEG activity during baseline and exposure to a neutral, a positive, a negative, and an accident-related picture. Differences in brain asymmetry between groups were observed only during exposure to trauma-related material. PTSD and subsyndromal PTSD patients showed a pattern of enhanced right anterior and posterior activation, whereas non-PTSD with MVA participants showed the opposite pattern. Furthermore, posterior asymmetry in nontraumatized healthy controls varied with gender, with female participants showing a pattern of higher right posterior activation. The results support the hypothesis that symptomatic MVA survivors are characterized by a pattern of right hemisphere activation that is associated with anxious arousal and symptoms of PTSD during processing of trauma-specific information.     

Enhanced perceptual priming for neutral stimuli in a traumatic context: A pathway to intrusive memories?

Clinical observations suggest that re-experiencing symptoms are triggered by stimuli that are perceptually similar to those present shortly before the trauma or its worst moments. Two experiments investigated the possible role of perceptual priming in this phenomenon. Volunteers (N = 28, N = 62) watched a series of "traumatic" and neutral picture stories, and completed blurred object identification (priming) and recognition memory tasks. Neutral objects that immediately preceded the "traumatic" stories were more strongly primed, but not better recognised, than objects from neutral stories. Enhanced priming predicted subsequent re-experiencing symptoms. The results support the role of perceptual priming in re-experiencing.     

Measuring affective clarity indirectly: individual differences in response latencies of state

This research investigated a new method to measure momentary affective clarity indirectly, which is based on latencies of responses to state affect items. Three studies revealed that this indirect measure of momentary clarity demonstrated high reliability and stability as well as convergent and predictive validity. The indirect measure was associated with dispositional clarity when the concept of clarity was activated before measuring response latencies (Studies 1 and 2) and was related to self-reports of momentary clarity (Study 3). Furthermore, Study 3 demonstrated that indirectly measured clarity decreased after an affectively complex film. Indirectly, but not directly, measured momentary clarity predicted a more positive affective state at the end of the study. This effect was mediated by affect regulation.     

The structure of emotional expressivity: each emotion counts

Several models of the dimensionality of emotional expressivity were examined in a multitrait-multimethod study. Targets and peer raters completed measures of the target's emotional expressivity (Berkeley Expressivity Questionnaire. BEQ; J. J. Gross & O. P. John, 1995; and a measure of emotion-specific expression) and the Big 5 personality dimensions. The results of structural equation modeling and analysis of variance revealed that an emotion-specific model was superior to models of valence-specific or unidimensional expressivity. The distinct emotions differed in their relations with the dimensions of the 5-factor model. These results were corroborated by self- and other reports. Finally, the degree of convergence between self- and other ratings differed between emotions, demonstrating the multidimensional character of emotional expressivity.     

Building blocks of idea generation and implementation in teams: A meta-analysis of team design and team creativity and innovation

Although organizations increasingly rely on teams to innovate, little systematic knowledge exists about how to design teams to do so. Building on the model of collaborative creativity and innovation and synthesizing findings from published and unpublished studies, this meta-analysis examines the role of team design on team creativity and innovation. We used random-effects meta-analysis to cumulate the correlations between different features of team design and team creativity or team innovation from 134 field studies representing 11,353 teams and 35 studies representing 2,485 student teams. We found that team tenure is curvilinearly related, autonomy-supportive leadership, task interdependence, and goal interdependence are positively related, and demographic diversity and team size are unrelated to team creativity and innovation. Examining meta-analytic path models, we found that task interdependence and supportive leadership positively relate to team creativity and innovation via team collaboration and team potency. In accounting for the literature, we found a dearth of studies examining team processes, some types of diversity such as racial diversity, and the role of team member turnover. We conclude by providing directions for future research and practical guidance about increasing team creativity and innovation through team design.     

Prism adaptation changes the subjective proprioceptive localization of the hands

Prism adaptation involves a proprioceptive, a visual and a motor component. As the existing paradigms are not able to distinguish between these three components, the contribution of the proprioceptive component remains unclear. In the current study, a proprioceptive judgement task, in the absence of motor responses, was used to investigate how prism adaptation would specifically influences the felt position of the hands in healthy participants. The task was administered before and after adaptation to left and right displacing prisms using either the left or the right hand during the adaptation procedure. The results appeared to suggest that the prisms induced a drift in the felt position of the hands, although the after‐effect depended on the combination of the pointing hand and the visual deviation induced by prisms. The results are interpreted as in line with the hypothesis of an asymmetrical neural architecture of somatosensory processing. Moreover, the passive proprioception of the hand position revealed different effects of proprioceptive re‐alignment compared to active pointing straight ahead: different mechanisms about how visuo‐proprioceptive discrepancy is resolved were hypothesized.     

Evolving from Clinical to Positive Psychology: Understanding and Measuring Patients’ Strengths: A Pilot Study

Empirical evidence suggests that concentrating on patients’ internal and external strengths serves a preventative function against psychopathology. However, standardized tools assessing strengths of patients suffering from mental disorders are rare and often limited to research purposes. As current practice in mental health rarely stresses the importance of patients’ personal resources, the feasibility of strengths-based assessments has rarely been validated within such a population. We designed a new instrument, the Strengths Q-sort Self-Assessment Scale, aimed at identifying patients’ strengths profile. This new scale measures 30 strengths classified in three sections: (i) personal characteristics, (ii) hobbies/passions, (iii) environmental/social strengths. In order to be adjusted for patients with cognitive or language impairments, this instrument is based on a Q-Sort method with figurative items. The aim of this study was to test the feasibility and acceptability of this scale in a sample of 21 psychiatric patients. Preliminary results showed that this tool can easily be administered and is well appreciated by patients. Feedback from clinicians highlight the benefits of identifying the strengths profiles in order to help defining realistic shared clinical objectives based on patients’ strengths.     

Self-control trumps work motivation in predicting job search behavior

Current labor market entrants face an increasingly challenging job search process. Effective guidance of job seekers requires identification of relevant job search skills. Self-control (i.e., the ability to control one's thoughts, actions, and response tendencies in view of a long-term goal, such as finding employment) is assumed to be one such relevant job search skill. The current study is the first to empirically assess the importance of self-control in the job search process. This is compared to the role of motivation, which is generally considered a crucial predictor of job searching. Based on a sample of 403 Dutch prospective vocational training graduates, we found that higher levels of self-control were related to higher levels of preparatory job search behavior and job search intentions half a year later, shortly before labor market entrance. Self-control was a significantly stronger predictor of job searching than work motivation. Moreover, relations between self-control and job searching were largely independent of motivation, which may suggest that job-seekers benefit from self-control through adaptive habits and routines that are unaffected by motivation. We propose that job search interventions, which traditionally focus on strengthening motivation, may benefit from a stronger focus on improving self-control skills.     

Effects of Music Training on Attention,Processing Speed and Cognitive Music Abilities—Findings from a Longitudinal Study

The present study addresses visual attention and processing speed in primary school children (N = 345; 7–8 years of age) who received either music (MC) or natural science training (NC) over a period of 18 months. Dependent variables were collected three times (T1–T3) and included measures for processing speed, visual attention and cognitive music abilities. They were submitted to latent or manifest change models including socioeconomic status and basic cognitive functions as covariates. Groups performed similarly in all dependent tasks at baseline (T1). MC showed significant increases in processing speed as well as in music abilities from T2 to T3 and increases in rhythmic abilities from T1 to T2. Although MC also showed increases in both processing speed and visual attention over time, they were at a small advantage with respect to the former and at a clear disadvantage with respect to the latter measure as compared to NC.
