The Moderation Effect of Approach Motivation Between Schizotypy and Creative Ideational Behavior.

Introduction: The schizotypy-creativity link has been studied from different perspectives over the past few decades, yet the results of this relationship are inconsistent in the literature. Previous studies have suggested that two basic motivational systems-Behavioral Inhibition System (BIS, avoidance motivation) and Behavioral Activation System (BAS, approach motivation)-underlie the relationship between schizotypy and creativity. Few empirical studies, however, have examined how the relationship interacts with other variables. This study fills these gaps and explores the role of the approach and avoidance motivation assessed by trait behavioral activation and inhibition in the link between schizotypy as a dimensional personality trait and creative ideational behavior as a measure of creativity. Method: Undergraduate students (N = 388) completed questionnaires including the Schizotypal Personality Questionnaire (SPQ) measuring 3 dimensions of schizotypy, Runco Ideational Behavior Scale (RIBS) measuring creative ideational behavior, and BIS/BAS Scales measuring trait behavioral motivation. Bivariate Pearson correlation was computed, and hierarchical linear regression was performed to explore the effects of schizotypy, BIS/BAS, and their interaction on creative ideational behavior. The conditional effect of schizotypy based on different levels of the moderator was further tested. Results: The total score, positive dimension and disorganized dimension of SPQ were all positively correlated with RIBS, BAS, and BIS. Negative dimension of SPQ was not significantly correlated with the RIBS score but was positively correlated with BIS. Additionally, after controlling gender and age, BAS significantly moderated the relationship between the positive and disorganized dimensions of schizotypy and creative ideational behavior measured by RIBS. However, BIS was not a significant moderator. Discussion: The findings of this study regarding the relationships between different dimensions of schizotypy, two motivational systems, and creative ideational behavior were mostly consistent with previous findings. The significant moderated effect of BAS on the relationship between two dimensions of schizotypy and creative ideational behavior made significant contributions to the understanding of the relationship between schizotypy and creativity.

P3b correlates of inspection time.

Both P3b and the inspection time (IT) are related with intelligence, yet the P3b correlates of IT are not well understood. This event-related potential study addressed this question by asking participants (N = 28) to perform an IT task. There were three IT conditions with different levels of discriminative stimulus duration, i.e., 33 ms, 67 ms, and 100 ms, and a control condition with no target presentation (0 ms condition). We also measured participants' processing speed with four Elementary Cognitive Tests (ECTs), including a Simple Reaction Time task (SRT), two Choice Reaction Time tasks (CRTs), and a Pattern Discrimination task (PD). Results revealed that an increase in P3b latency with longer duration of the discriminative stimulus. Moreover, the P3b latency was negatively correlated with the accuracy of the IT task in the 33 ms condition, but not evident in the 67 and 100 ms conditions. Furthermore, the P3b latency of the 33 ms condition was positively correlated with the RT of the SRT, but not related with the RTs of CRTs or PD. A significant main effect of duration on the amplitude of P1 was also found. We conclude that the present study provides the neurophysiological correlates of the IT task, and those who are able to accurately perceive and process very briefly presented stimuli have a higher speed of information process, reflected by the P3b latency, yet this relationship is more obvious in the most difficult condition. Combined, our results suggest that P3b is related with the closure of a perceptual epoch to form the neural representation of a stimulus, in support of the "context closure" hypothesis.

Effects of musical expertise on line section and line extension.

Background: This study investigated whether music training led to better length estimation and/or rightward bias by comparing the performance of musicians (pianists) and non-musicians on performance of line sections and line extensions. Methods: One hundred and sixteen participants, among them 62 musicians and 54 non-musicians, participated in the present study, completed line section and line extension task under three conditions: 1/2, 1/3 and 2/3. Results: The mixed repeated measures ANOVA analysis revealed a significant group × condition interaction, that the musicians were more accurate than non-musicians in all the line section tasks and showed no obvious pseudoneglect, while their overall performance on the line extension tasks was comparable to the non-musicians, and only performed more accurately in the 1/2 line extension condition. Conclusion: These findings indicated that there was a dissociation between the effects of music training on line section and line extension. This dissociation does not support the view that music training has a general beneficial effect on line estimation, and provides insight into a potentially important limit on the effects of music training on spatial cognition.

The Effects of the Creator's Situation on Creativity Evaluation: The Rater's Cognitive Empathy and Affective Empathy Matter in Rating Creative Works.

Successful intelligence theory suggests that creativity is necessary for personal achievement outside of intelligence. Unlike intelligence, creativity can develop in a supportive environment. People should consider the situation of disadvantaged groups, which are characterized by low personal achievement and a bad growth environment in creativity evaluation from a caring perspective. This study focuses on the effect of the creator's situation on creative evaluation and the role of the rater's empathy (i.e., cognitive empathy and affective empathy) and sympathy in creative evaluation. Four pairs of creator's situations (by age, physical state, family situation, and economic state) were designed to represent people with disadvantages or advantages. A between-subject design was used with 590 undergraduate students randomly assigned to eight sub-conditions. The participants were asked to assess three products in eight situations. The rater's empathy and sympathy in creativity evaluation were explored in the overall disadvantage (N = 300) and advantage (N = 290) conditions. The results showed that the participants only provided significantly higher ratings to the creative product made by a child. Cognitive empathy only predicted a creative rating under disadvantaged conditions, and affective empathy negatively moderated this effect. Affective empathy only predicted a creative rating under advantage conditions, and cognitive empathy positively moderated this effect. Affective empathy only predicted a creative rating under advantage conditions, and cognitive empathy positively moderated this effect. The possible mechanisms of the effect and implications for the establishment of a supportive environment for creativity and creativity teaching practice were discussed.

A comparison of the differences in the way parents and grandparents interact with children and their effects on children's creative performance.

As grandparents' involvement in parenting becomes more common, it is valuable to understand the differences between grandparenting and parenting and how these differences affect children. To elucidate the differences between grandparenting and parenting and their effects on children's creativity performance, children's performance on creativity tasks after grandparent-child interactions and parent-child interactions were compared, and the behavioral differences between grandparents and parents when interacting with children were discussed. In this study, grandparents and parents were asked to interact with children separately, and creativity performance was measured before and after adult-child interactions. The results showed that children's creative performance improved significantly after parent-child interactions, while there was little change after grandparent-child interactions. In addition, according to parental investment theory, parents provided children with more cognitive and interpersonal resources during the interaction compared to grandparents.

Effects of Acute Alcohol Intoxication on Empathic Neural Responses for Pain.

The questions whether and how empathy for pain can be modulated by acute alcohol intoxication in the non-dependent population remain unanswered. To address these questions, a double-blind, placebo-controlled, within-subject study design was adopted in this study, in which healthy social drinkers were asked to complete a pain-judgment task using pictures depicting others' body parts in painful or non-painful situations during fMRI scanning, either under the influence of alcohol intoxication or placebo conditions. Empathic neural activity for pain was reduced by alcohol intoxication only in the dorsal anterior cingulate cortex (dACC). More interestingly, we observed that empathic neural activity for pain in the right anterior insula (rAI) was significantly correlated with trait empathy only after alcohol intoxication, along with impaired functional connectivity between the rAI and the fronto-parietal attention network. Our results reveal that alcohol intoxication not only inhibits empathic neural responses for pain but also leads to trait empathy inflation, possibly via impaired top-down attentional control. These findings help to explain the neural mechanism underlying alcohol-related social problems.
