Tracking the speech signal – Time-locked MEG signals during perception of ultra-fast and moderately fast speech in blind and in sighted listeners

Blind people can learn to understand speech at ultra-high syllable rates (ca. 20 syllables/s), a capability associated with hemodynamic activation of the central-visual system. To further elucidate the neural mechanisms underlying this skill, magnetoencephalographic (MEG) measurements during listening to sentence utterances were cross-correlated with time courses derived from the speech signal (envelope, syllable onsets and pitch periodicity) to capture phase-locked MEG components (14 blind, 12 sighted subjects; speech rate = 8 or 16 syllables/s, pre-defined source regions: auditory and visual cortex, inferior frontal gyrus). Blind individuals showed stronger phase locking in auditory cortex than sighted controls, and right-hemisphere visual cortex activity correlated with syllable onsets in case of ultra-fast speech. Furthermore, inferior-frontal MEG components time-locked to pitch periodicity displayed opposite lateralization effects in sighted (towards right hemisphere) and blind subjects (left). Thus, ultra-fast speech comprehension in blind individuals appears associated with changes in early signal-related processing mechanisms both within and outside the central-auditory terrain.     

Honesty–humility and a person–situation interaction at work

Person–situation interactions have attracted researchers' attention for decades. Likewise, the current work focuses on the interaction of honesty–humility and situational conditions in bringing about counterproductive work behaviour (CWB). As such, we introduce perceptions of organizational politics as a situational construct representing an opportunity for CWB. In a sample of N = 148 employees we found that particularly individuals low in honesty–humility were affected by situational circumstances. By contrast, those high in honesty–humility reported practically the same (lower) amount of CWB independent of the level of perceptions of organizational politics. In other words, employees low in honesty–humility were especially likely to condition their behaviour on environmental factors, a result that mirrors previous findings.

Blame it on patriarchy: More sexist attitudes are associated with stronger consideration of cosmetic surgery for oneself and one's partner

In the present work, we examined associations between oppressive, sexist beliefs and consideration of cosmetic surgery for oneself and also endorsement of cosmetic surgery for one's romantic partner. A total of 554 German‐speaking volunteers from the community, mainly in Austria, completed measures of consideration of cosmetic surgery and three measures of sexist attitudes, while a subset of participants in romantic relationships completed a measure of endorsement of cosmetic surgery for their partners along with the measures of sexism. Preliminary analyses showed that women and single respondents were more likely to consider having cosmetic surgery than men and committed respondents, respectively. Further analyses showed that consideration of cosmetic surgery for oneself was significantly associated with sexist attitudes, particularly hostile attitudes to women. In addition, among participants in a relationship, sexist attitudes were associated with endorsement of cosmetic surgery for one's partner. These results indicate that attitudes to cosmetic surgery for oneself and one's partner are shaped by gender‐ideological belief systems in patriarchal societies. Possible implications for understanding the motivations for having cosmetic surgery, among both single respondents and couples, are discussed.     

Exploring the Effects of Creativity Training on Creative Performance and Creative Self‐Efficacy: Evidence from a Longitudinal Study

In organizations and educational institutions, creativity trainings are the preferred approach to enhancing individual creative abilities. However, three issues regarding these trainings still remain largely unsolved. First, the question of how long‐lasting creativity training effects are has not been sufficiently answered so far. Second, the question arises whether all participants benefit from such trainings equally in terms of their creative performance (CP). Third, an increasing number of studies have shown that creativity trainings may also be able to increase participants' creative self‐efficacy (CSE), that is, the confidence in one's own creativity. Other studies, however, did not find evidence for this effect. Therefore, this article aims to address these issues by analyzing data from three measurement waves. Results reveal that participants' CP increased during the training and decreased only slightly 4 weeks after the training. Additionally, we found an effect of diminishing training returns in that the higher a participant's CP before the training the lower the training effect was. In contrast to most prior literature, we found no support for an effect of creativity training on participants' CSE. We discuss these findings and offer implications for both theory and practice. Finally, we state this study's limitations and derive avenues for further research.     

Monkey see,monkey do: The effect of social influence on selective‐exposure bias

Selective‐exposure bias refers to the tendency to predominantly seek out attitude‐consistent information and avoid attitude‐inconsistent information. Although researchers have proposed and tested several underlying psychological factors that might contribute to this tendency, the potential role of social influence has not been addressed. In the present research, we address this issue. In four experiments (total N = 645), participants’ selective‐exposure bias was significantly reduced when the bias was portrayed as non‐normative (vs. normative). In Experiment 4, we obtained evidence for the possibility that this social‐norm manipulation could result in effects on attitudes through information selection. Overall, this research contributes novel evidence for the effect of social influence on selective‐exposure bias.     

Mindfulness facets,trait emotional intelligence,emotional distress,and multiple health behaviors: A serial two‐mediator model

In the present study, we tested a serial mindfulness facets‐trait emotional intelligence (TEI)‐emotional distress‐multiple health behaviors mediation model in a sample of N = 427 German‐speaking occupational therapists. The mindfulness facets‐TEI‐emotional distress section of the mediation model revealed partial mediation for the mindfulness facets Act with awareness (Act/Aware) and Accept without judgment (Accept); inconsistent mediation was found for the Describe facet. The serial two‐mediator model included three mediational pathways that may link each of the four mindfulness facets with multiple health behaviors. Eight out of 12 indirect effects reached significance and fully mediated the links between Act/Aware and Describe to multiple health behaviors; partial mediation was found for Accept. The mindfulness facet Observe was most relevant for multiple health behaviors, but its relation was not amenable to mediation. Implications of the findings will be discussed.     

Gaze behaviour in hereditary prosopagnosia

Prosopagnosia is the inability to recognize someone by the face alone in the absence of sensory or intellectual impairment. In contrast to the acquired form of prosopagnosia we studied the congenital form. Since we could recently show that this form is inherited as a simple monogenic trait we called it hereditary form. To determine whether not only face recognition and neuronal processing but also the perceptual acquisition of facial information is specific to prosopagnosia, we studied the gaze behaviour of four hereditary prosopagnosics in comparison to matched control subjects. This rarely studied form of prosopagnosia ensures that deficits are limited to face recognition. Whereas the control participants focused their gaze on the central facial features, the hereditary prosopagnosics showed a significantly different gaze behaviour. They had a more dispersed gaze and also fixated external facial features. Thus, the face recognition impairment of the hereditary prosopagnosics is reflected in their gaze behaviour.     

Further investigation of the validity and reliability of the photographic figure rating scale for body image assessment

Previous studies have not fully investigated the psychometric properties of the Photographic Figure Rating Scale (PFRS). In 2 studies, we report on the test-retest reliability and convergent validity of ratings derived from the PFRS. In Study 1, 322 female university students in Britain provided self-ratings on the PFRS and objectively measured body mass index (BMI); a subsample of 132 women also completed the task after 5 weeks. In Study 2, 243 women from the community in Austria completed the PFRS along with a battery of other body image scales. Results of Study 1 showed that ratings on the PFRS had good test-retest reliability (all rs > .87) and good convergent validity in relation to BMI. Results of Study 2 showed that PFRS-derived body dissatisfaction scores were significantly correlated with a range of body image variables. These results provide evidence for the convergent validity and good test-retest reliability of the PFRS.
