“…Performance in the two priming tasks was good and comparable to performance in similar studies (e.g., Akbari Chermahini & Hommel, 2010). Participants produced about seven correct responses, on average, in the RAT (M = 7.2 and SD = 2.7) and used about 26 different categories in the AUT (M = 26.3 and SD = 7.3).…”

Increasing evidence suggests that people may cognitively represent themselves and others just like any other, nonsocial event. Here, we provide evidence that the degree of self-other integration (as reflected by the joint Simon effect; JSE) is systematically affected by the control characteristics of temporally overlapping but unrelated and nonsocial creativity tasks. In particular, the JSE was found to be larger in the context of a divergent-thinking task (alternate uses task) than in the context of a convergent-thinking task (remote association task). This suggests that self-other integration and action corepresentation are controlled by domain-general cognitivecontrol parameters that regulate the integrativeness (strong vs. weak top-down control and a resulting narrow vs. broad attentional focus) of information processing irrespective of its social implications.

“…Interestingly, schizophrenia is linked to even lower thalamic D2 receptor densities, placing creative persons on a gradient between normal and schizophrenic individuals. This idea is reinforced by work showing that spontaneous eye-blink frequencies of individuals that score high on divergent thinking tests tend to fall between those of normal and schizophrenic persons (Chermahini and Hommel 2010). The latter group is plagued by a flow of bizarre associations.…”

ABSTRACT. Recent studies provide compelling evidence for the idea that creative thinking draws upon two kinds of processes linked to distinct physiological features, and stimulated under different conditions. In short, the fast system-I produces intuition whereas the slow and deliberate system-II produces reasoning. System-I can help see novel solutions and associations instantaneously, but is prone to error. System-II has other biases, but can help checking and modifying the system-I results. Although thinking is the core business of science, the accepted ways of doing our work focus almost entirely on facilitating system-II. We discuss the role of system-I thinking in past scientific breakthroughs, and argue that scientific progress may be catalyzed by creating conditions for such associative intuitive thinking in our academic lives and in education. Unstructured socializing time, education for daring exploration, and cooperation with the arts are among the potential elements. Because such activities may be looked upon as procrastination rather than work, deliberate effort is needed to counteract our systematic bias.

“…Mesolimbic dopamine activation during sleep may influence novelty seeking and creative drive . Indeed, the dopaminergic system is thought to contribute to creativity, in particular divergent thinking, cognitive flexibility, innovative insights, and associative thinking (Chermahini and Hommel 2010;Flaherty 2005;Takeuchi et al 2010). Further evidence comes from Parkinson's disease patients under dopaminergic treatment, who may show increased artistic drive and productivity (Inzelberg 2013;Kulisevsky et al 2009).…”

In this chapter, we review studies investigating the role of sleep in emotional functions. In particular, evidence has recently accumulated to show that brain regions involved in the processing of emotional and reward-related information are activated during sleep. We suggest that such activation of emotional and reward systems during sleep underlies the reprocessing and consolidation of memories with a high affective and motivational relevance for the organism. We also propose that these mechanisms occurring during sleep promote adapted cognitive and emotional responses in the waking state, including overnight performance improvement, creativity, and sexual functions. Activation across emotional-limbic circuits during sleep also appears to promote emotional maturation and the emergence of consciousness in the developing brain.
