The Importance of the Default Mode Network in Creativity—A Structural MRI Study

Anecdotal reports as well as behavioral studies have suggested that creative performance benefits from unconscious processes. So far, however, little is known about how creative ideas arise from the brain. In the current study, we aimed to investigate the neural correlates of creativity by means of structural MRI research. Given that unconscious and less controlled processes are important in creative thinking, structural brain research may find a positive correlation between well‐established creativity measures and cortical thickness in brain structures of the default mode network (i.e., the counterpart of the cognitive control network). Individuals performed the Alternative Uses task by which an individual's cognitive flexibility and the average uniqueness and average creativity of a participant's ideas were assessed. We computed optimized voxel‐based‐morphometry (VBM) to explore the correlation between inter‐individual differences in creativity and inter‐individual differences in gray matter volume. For all creativity measures, a positive correlation was found between creative performance and gray matter volume of the default mode network. These findings support the idea that the default mode network is important in creativity, and provide neurostructural support for the idea that unconscious forms of information processing are important in creativity. Theoretical and practical implications are discussed.     

Terrorist threat and employees' perceived ability to cope with organizational change

This study investigated the impact of the perceived threat of terrorism on employees' ability to cope with organizational change as well as potentially underlying psychological mechanisms related to work satisfaction and initiative. Three days after the 2006 thwarted terrorist attacks in the United Kingdom, participants were reminded of terrorist threat (by pictures of terrorist attacks) reported lower levels in their ability to cope with organizational change, as well as lower levels of work satisfaction, than did participants who were not reminded of terrorist threat. Three months later, the same terror salience manipulation had no differential effect on these variables. Mediation analyses revealed that work satisfaction mediated the impact of terror salience on employees' ability to cope with organizational change.     

Religiosity/Spirituality of German Doctors in Private Practice and Likelihood of Addressing R/S Issues with Patients

This study examined the self-assessed religiosity and spirituality (R/S) of a representative sample of German physicians in private practice (n = 414) and how this related to their addressing R/S issues with patients. The majority of physicians (49.3 %) reported a Protestant denomination, with the remainder indicating mainly either Catholic (12.5 %) or none (31.9 %). A significant proportion perceived themselves as either religious (42.8 %) or spiritual (29.0 %). Women were more likely to rate themselves R/S than did men. Women (compared to men) were also somewhat more likely to attend religious services (7.4 vs. 2.1 % at least once a week) and participate in private religious activities (14.9 vs. 13.7 % at least daily), although these differences were not statistically significant. The majority of physicians (67.2 %) never/seldom addressed R/S issues with a typical patient. Physicians with higher self-perceived R/S and more frequent public and private religious activity were much more likely to address R/S issues with patients. Implications for patient care and future research are discussed.     

To help or not to help an outgroup member: The role of the target's individual attributes in resolving potential helpers' motivational conflict

When people are faced with the decision of whether or not to help an outgroup member, they often experience conflicting motivational tendencies due to the concurrent presence of factors prompting help and factors prompting non‐help. We argue that one way of how people deal with this conflict is by taking a closer look at the target's individual attributes, especially at those indicating the target's benevolence. Findings of Experiment 1 (N = 96), in which we manipulated intercultural dissimilarity between participants and a (fictitious) recipient of help and normative pressure to help as two factors affecting motivational conflict, support this basic assumption. Specifically, response latencies analyses confirmed that participants assigned a culturally highly dissimilar target spent more time on inspecting target‐related information when normative pressure, and thus motivational conflict, was high than when it was low. Experiment 2 (N = 141) extended these findings by demonstrating that providing potential helpers with explicit information about an outgroup member's benevolence increased helping intentions through reducing their negative interaction expectancies (and thus motivational conflict). As expected, this mediational relationship could only be observed for participants assigned a culturally highly dissimilar target. Experiment 3 (N = 46) replicated these mediation findings in a within‐subjects design. Copyright © 2014 John Wiley & Sons, Ltd.     

Exogenous attention can be counter-selective: onset cues disrupt sensitivity to color changes

In peripheral spatial cueing paradigms, exogenous attentional capture is commonly observed after salient onset cues or with cues contingent on target characteristics. We proposed that exogenously captured attention disrupts the selectivity to target features. We tested this by experimentally emulating the everyday observation that in a viewing situation in which the observer is monitoring a stationary display fort change to occur, the onset of a salient stimulus (onset cue) or a change in a stationary stimulus similar to the expected one (contingent cue) has a distracting effect. As predicted, we found that both types of cues reduced the target detection sensitivity but enhanced the bias to respond in a go-nogo-paradigm. With the onset cue, the sensitivity loss was more pronounced at the side of the cue, whereas the contingent cue affected both sides likewise. Moreover, the effects of the onset cue interacted with the task difficulty: the more selectivity a task required the more immune it was against disruption, but the more likely was a response. We concluded that onset capture disrupts selective attention by adding noise to the processing of the target location. The effects of contingent capture could be explained with cue-target confounding. Finally, we suggest a new model of attentional capture in which exogenous and endogenous components interact in a dynamic way.     

Auditory spatial negative priming: What is remembered of irrelevant sounds and their locations?

The categorization and identification of previously ignored visual or auditory stimuli is typically slowed down—a phenomenon that has been called the negative priming effect and can be explained by the episodic retrieval of response-inadequate prime information and/or an inhibitory model. A similar after-effect has been found in visuospatial tasks: participants are slowed down in localizing a visual stimulus that appears at a previously ignored location. In the auditory modality, however, such an after-effect of ignoring a sound at a specific location has never been reported. Instead, participants are impaired in their localization performance when the sound at the previously ignored location changes identity, a finding which is compatible with the so-called feature-mismatch hypothesis. Here, we describe the properties of auditory spatial in contrast to visuospatial negative priming and report two experiments that specify the nature of this auditory after-effect. Experiment 1 shows that the detection of identity-location mismatches is a genuinely auditory phenomenon that can be replicated even when the sound sources are invisible. Experiment 2 reveals that the detection of sound-identity mismatches in the probe depends on the processing demands in the prime. This finding implies that the localization of irrelevant sound sources is not the inevitable consequence of processing the auditory prime scenario but depends on the difficulty of the target search process among distractor sounds.     

Who Belongs to Me? Social Relationship and Personality Characteristics in the Transition to Young Adulthood

Not much is known about how social network characteristics change in the transition out of school and what role Big Five personality plays in this context. The aim of this paper was twofold. First, we explored changes in social network and relationship characteristics across the transition out of secondary school. Second, we examined within‐person and between‐person effects of personality on these social network changes. Results based on a series of multilevel models to a longitudinal sample of 2287 young adults revealed four main findings. First, social networks increased in size, and this increase was mainly due to a larger number of nonkin. Stable social networks during the transition consisted mainly of family ties but were generally characterized by high closeness. Second, extraversion and openness consistently predicted network size, whereas agreeableness predicted network overlap. Third, increases in emotional closeness were found only for kin; closeness was generally lower for unstable relationships. Fourth, changes in emotional closeness were related to personality, particularly neuroticism, agreeableness, and conscientiousness for stable relationships; for unstable relationships, however, closeness was related to extraversion and openness. The article concludes by discussing the role of personality for social relationship development and the active moulding of social networks in young adulthood.
