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.     

Confinement has no effect on visual space perception: The results of the Mars-500 experiment

People confined to a closed space live in a visual environment that differs from a natural open-space environment in several respects. The view is restricted to no more than a few meters, and nearby objects cannot be perceived relative to the position of a horizon. Thus, one might expect to find changes in visual space perception as a consequence of the prolonged experience of confinement. The subjects in our experimental study were participants of the Mars-500 project and spent nearly a year and a half isolated from the outside world during a simulated mission to Mars. The participants were presented with a battery of computer-based psychophysical tests examining their performance on various 3-D perception tasks, and we monitored changes in their perceptual performance throughout their confinement. Contrary to our expectations, no serious effect of the confinement on the crewmembers’ 3-D perception was observed in any experiment. Several interpretations of these findings are discussed, including the possibilities that (1) the crewmembers’ 3-D perception really did not change significantly, (2) changes in 3-D perception were manifested in the precision rather than the accuracy of perceptual judgments, and/or (3) the experimental conditions and the group sample were problematic.     

The effect of iconicity of visual displays on statistical reasoning: evidence in favor of the null hypothesis

Knowing which properties of visual displays facilitate statistical reasoning bears practical and theoretical implications. Therefore, we studied the effect of one property of visual diplays?– iconicity (i.e., the resemblance of a visual sign to its referent)?– on Bayesian reasoning. Two main accounts of statistical reasoning predict different effect of iconicity on Bayesian reasoning. The ecological-rationality account predicts a positive iconicity effect, because more highly iconic signs resemble more individuated objects, which tap better into an evolutionary-designed frequency-coding mechanism that, in turn, facilitates Bayesian reasoning. The nested-sets account predicts a null iconicity effect, because iconicity does not affect the salience of a nested-sets structure—the factor facilitating Bayesian reasoning processed by a general reasoning mechanism. In two well-powered experiments (N = 577), we found no support for a positive iconicity effect across different iconicity levels that were manipulated in different visual displays (meta-analytical overall effect: log OR = ?0.13, 95 % CI [?0.53, 0.28]). A Bayes factor analysis provided strong evidence in favor of the null hypothesis—the null iconicity effect. Thus, these findings corroborate the nested-sets rather than the ecological-rationality account of statistical reasoning.     

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.

Social Desirability Scales as Indicators of Self-Enhancement and Impression Management

This article presents 2 studies testing Paulhus's (2002) assumption that unconscious self-enhancement and conscious impression management represent separate processes of socially desirable responding (SDR) that can be observed within 2 content domains (egoistic and moralistic bias). In Study 1, we devised egoistic and moralistic SDR scales intended to measure self-enhancement in honest responding and impression management under demands for positive self-presentation. In Study 2, we correlated scores on these scales with external indicators of self-enhancement and impression management. In honest responding, both SDR scales most strongly correlated with self-enhancement indicators, whereas under demands for positive self-presentation they correlated more strongly with external measures of impression management.
