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.     

Goal setting via videoconferencing

In two experiments (N = 126, N = 120) telework in an advertising company was simulated. Participants communicated either face-to-face or via a PC-videoconference with a supervisor who motivated employees to solve brainstorming tasks using several goal setting strategies. In addition, communication with the supervisor prior to goal setting was manipulated to examine the impact of a personal meeting with the supervisor and to investigate the effect of having some prior experience with this technology. In both experiments, stimulating challenging goals improved performance compared to “do your best” instructions when goal setting was conducted via a videoconference. Moreover, it was found that participative goal setting was more effective than directive goal setting. However, a prior personal meeting with a supervisor or an additional interaction via videoconference prior to goal setting had no impact on performance or the effectiveness of goal setting. In sum, these findings indicate that goal setting effects are robust and can be found even if communication is based on a videoconference. When difficult goals have to be set within a videoconference, participative goal setting strategies are most effective.     

Intrusive re‐experiencing in post‐traumatic stress disorder: Phenomenology,theory, and therapy

The article describes features of trauma memories in post‐traumatic stress disorder (PTSD), including characteristics of unintentional re‐experiencing symptoms and intentional recall of trauma narratives. Re‐experiencing symptoms are usually sensory impressions and emotional responses from the trauma that appear to lack a time perspective and a context. The vast majority of intrusive memories can be interpreted as re‐experiencing of warning signals, i.e., stimuli that signalled the onset of the trauma or of moments when the meaning of the event changed for the worse. Triggers of re‐experiencing symptoms include stimuli that have perceptual similarity to cues accompanying the traumatic event. Intentional recall of the trauma in PTSD may be characterised by confusion about temporal order, and difficulty in accessing important details, both of which contribute to problematic appraisals. Recall tends to be disjointed. When patients with PTSD deliberately recall the worst moments of the trauma, they often do not access other relevant (usually subsequent) information that would correct impressions/predictions made at the time. A theoretical analysis of re‐experiencing symptoms and their triggers is offered, and implications for treatment are discussed. These include the need to actively incorporate updating information ( “I know now …”) into the worst moments of the trauma memory, and to train patients to discriminate between the stimuli that were present during the trauma ( “then”) and the innocuous triggers of re‐experiencing symptoms ( “now”).     

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.     

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.     

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.

A within-person approach to the relation between quality of task motivation,performance and job satisfaction in everyday working life

Research generally shows that autonomous forms of motivation are associated with higher performance and job satisfaction, whereas controlled forms of motivation are linked to worse outcomes. These relationships are largely based on between-persons data from cross-sectional studies or longitudinal studies with few measurement points. However, motivation quality, performance, and job satisfaction can vary considerably from day to day and from task to task. It is unclear whether and how these experiences and behaviors covary over time within individuals at work in daily life. The present study assessed this using a diary approach. With a default protocol of 30 working days, an ecological momentary assessment application prompted 19 white-collar workers five times a day to report their autonomous and controlled motivation for work tasks and their productivity and job satisfaction at the end of each day. Fourteen participants gathered sufficient data to compute within-person relations and individual networks. At the between-person level, results were somewhat in line with prior survey-based research, whereas results at the within-person level present more nuanced findings and demonstrate that these will not inherently align with previous between-person findings. Individual network analyses indicated considerable interindividual heterogeneity, especially in the relationships between motivation and job satisfaction. In conclusion, these findings point to significant variability in the observed relations between task-related motivation, performance and job satisfaction in everyday life, and highlight the added value of a within person approach and individual networks in addition to between-persons approaches. The implications of these findings for occupational wellbeing research are discussed.

     

The anaphase promoting complex is required for memory function in mice

Learning and memory processes critically involve the orchestrated regulation of de novo protein synthesis. On the other hand it has become clear that regulated protein degradation also plays a major role in neuronal plasticity and learning behavior. One of the key pathways mediating protein degradation is proteosomal protein destruction. The anaphase-promoting complex/cyclosome (APC/C) is an E3 ubiquitin ligase that targets proteins for proteosomal degradation by the 26S proteasome. While the APC/C is essential for cell cycle progression it is also expressed in postmitotic neurons where it has been implicated with axonal outgrowth and neuronal survival. In this study we addressed the role of APC/C in learning and memory function by generating mice that lack the essential subunit APC2 from excitatory neurons of the adult forebrain. Those animals are viable but exhibit a severe impairment in the ability to extinct fear memories, a process critical for the treatment of anxiety diseases such as phobia or post-traumatic stress disorder. Since deregulated protein degradation and APC/C activity has been implicated with neurodegeneration we also analyzed the effect of Apc2 deletion in a mouse model for Alzheimer's disease. In our experimental setting loss of APC2 form principle forebrain neurons did not affect the course of pathology in an Alzheimer's disease mouse model. In conclusion, our data provides genetic evidence that APC/C activity in the adult forebrain is required for cognitive function.
