Novelty refers to the quality of an idea or product that is new unusual. It has been shown influence a broad range cognitive processes, such as increasing arousal and facilitating working memory. However, no studies have directly investigated effects novelty on control, particularly trade-off between proactive reactive control. The present study employed adapted AX Continuous Performance Task (AX-CPT) combined with electroencephalography (EEG) investigate impact control modes. behavioral results showed reaction times in BX trials were longer under novel conditions than common conditions, indicating participants may rely more and/or less when influenced by novelty. EEG smaller cue-P3 cue-locked theta-ERS novelty, suggesting might decrease including decreased maintenance utilization contextual information. Moreover, effect probe-locked was greater, while probe-P3 smaller. This indicates enhance increased conflict monitoring reduced response inhibition cost. findings suggest exposure can how individuals balance potentially causing bias towards

Teach a man to fish: Hyper-brain evidence on scaffolding strategy enhancing creativity acquisition and transfer

NeuroImage, Journal Year: 2024, Volume and Issue: 297, P. 120757 - 120757

Published: July 26, 2024

Creativity is an indispensable competency in today's innovation-driven society. Yet, the influences of instructional strategy, a key determinant educational outcomes, on creativity-fostering process remains unresolved mystery. We proposed that strategy affects creativity cultivation and further investigated intricate neural mechanisms underlying this relationship. In naturalistic laboratory setting, 66 instructor-learner dyads were randomized into three groups (scaffolding, explanation, control), with divergent thinking instructions separately. Functional near-infrared spectroscopy (fNIRS) hyperscanning simultaneously collected brain signals prefrontal cortex temporal-parietal junction regions. Results indicated learners instructed scaffolding demonstrated superior creative performance both acquisition (direct learning) transfer (use novel context) skills, compared to pretest levels. contrast, control explanation did not exhibit such effects. Notably, we also observed remarkable interbrain synchronization (INS) between instructors left frontal group, but or groups. Furthermore, INS positively predicted enhancements (acquisition transfer), indicating it crucial mechanism process. These findings reveal facilitates deepen our understanding creativity-fostering. The current study provides valuable insights for implementing teaching strategies fostering creativity.

Can rewards enhance creativity? Exploring the effects of real and hypothetical rewards on creative problem solving and neural mechanisms

Behavioral and Brain Functions, Journal Year: 2024, Volume and Issue: 20(1)

Published: Dec. 28, 2024

Reward cues have long been considered to enhance creative performance; however, little is known about whether rewards can affect problem solving by manipulating states of flexibility and persistence. This study sought elucidate the differential impacts real versus hypothetical on process utilizing Chinese compound remote association task. Behavioral analysis revealed a significantly enhanced solution rate response times in scenarios involving rewards, contrast those observed with rewards. Electrophysiological findings indicated that led more positive P200-600 amplitudes, stark amplitudes context These indicate impact associations contribute new insights into relationship between solving, highlighting crucial role persistence/flexibility formation creativity.
