Creative flow as optimized processing: Evidence from brain oscillations during jazz improvisations by expert and non-expert musicians.

Using a creative production task, jazz improvisation, we tested alternative hypotheses about the flow experience: (A) that it is a state of domain-specific processing optimized by experience and characterized by minimal interference from task-negative default-mode network (DMN) activity versus (B) that it recruits domain-general task-positive DMN activity supervised by the fronto-parietal control network (FPCN) to support ideation. We recorded jazz guitarists' electroencephalograms (EEGs) while they improvised to provided chord sequences. Their flow-states were measured with the Core Flow State Scale.

Retrieval dynamics in resolving relational inconsistency during verbal analogical reasoning.

Reasoning about verbal analogies requires selective retrieval of relevant relational information. A consequence of this may be that inhibitory processes in memory cause reduced recall of information associated with analogy-irrelevant relations. The current experiments apply the retrieval-induced forgetting framework to investigate the potential role of such inhibitory processes in analogical reasoning.

Pre-stimulus brain oscillations predict insight versus analytic problem-solving in an anagram task.

There are two general strategies for solving a problem. Insight is the sudden realization of a novel idea or problem solution accompanied by an "aha" experience. Analysis occurs in a conscious, deliberate fashion without an "aha" experience.

An insight-related neural reward signal.

Moments of insight, a phenomenon of creative cognition in which an idea suddenly emerges into awareness as an "Aha!" are often reported to be affectively positive experiences. We tested the hypothesis that problem-solving by insight is accompanied by neural reward processing. We recorded high-density EEGs while participants solved a series of anagrams.
