“…We found that tRNS produced a significant and large increase in RAT scores when compared to sham. This result is consistent with previous studies that used tDCS over PPC 1,7 and with neuroimaging studies, including EEG 61,62 and fMRI 63,64 . Zmigrod et al 7 found that anodal stimulation over right and anodal over left PPC produced a higher number of insight solutions to a Compound Remote Associates Task, a similar task to RAT used in the present study.…”

“…According to some authors 25 , a possible explanation for the finding of alpha power increase in PPC during insightful solutions may be interpreted as a suppression of sensory information, thus favoring the combination of remotely associated semantic information 25 . Studies that included fMRI 63,64 suggest that along with frontal brain regions (including DLPFC, ventrolateral PFC, medial PFC and IFG), PPC was involved in Compound Remote Associates Task performance. There are only two studies that used tDCS over the PPC 1,7 and their the results are in line with the evidence from neuroimaging studies.…”

Creativity pervades many areas of everyday life and is considered highly relevant in several human living domains. Previous literature suggests that the posterior parietal cortex (PPC) is related to creativity. However, none of previous studies have compared the effect of transcranial random noise stimulation (tRNS) over bilateral PPC on both verbal and visual divergent thinking (DT) and Remote Associates Test (RAT) in the same experimental design. Forty healthy participants were randomly assigned to tRNS (100–500 Hz) over bilateral PPC or sham group, for 15 min and current was set at 1.5 mA. Participants’ creativity skills were assessed before and after brain stimulation with the Unusual Uses and the Picture Completion subtests from the Torrance Test of Creative Thinking and the RAT. ANCOVA (baseline scores as covariate) results indicated that tRNS group had significantly higher scores at post-test in RAT and visual originality compared to sham group. Unusual Uses, on the other hand, was not significant. Improvement in RAT suggests the involvement of PPC during via insight solution which may reflect internally directed attention that helps the recombination of remotely associated information. The improvement in visual originality dimension from DT may be due to a higher internally directed attention while reducing externally oriented attention.

“…Congruent with recent research, sudden insights generally increase metacognitive feelings, including a subjective certainty that the insight is true (Hedne et al, 2016;Kizilirmak et al, 2019;Loesche et al, 2018;Steele, Johnson, & Medeiros, 2018). The study complements previous studies indicating that sudden insight (Danek, Fraps, von Müller, Grothe, & Öllinger, 2014a;Ohlsson, 1984) and positive affect (Isen & Reeve, 2005) generally foster intrinsic motivation.…”

The Aha-experience is the well-known hallmark of sudden insight. An integrative fluency account of the phenomenology of insight connects the four defining features of the Aha-experience: (1) A sudden insight leads to change in (2) processing fluency that increases (3) positive affect and (4) certainty that the insight is true. Several experimental studies have examined individual relationships between these defining features. However, no single study has examined the quantitative interrelationships of all components of the Aha-experience. In a retrospective study, we tested the fluency account of insight to further understand the Aha-experience. Bayesian statistics and structural equation modeling were used to the assess the theoretical model, with data comprising two independent samples (N ϭ 638). Results indicated that sudden insight increases fluency, positive affect, and subjective certainty, although the three dimensions are better seen as underlying components of general metacognitive feelings. In addition, we assessed the relationship among Aha-experience, sense of agency, motivation, and coping. Results indicated that metacognitive feelings mediate the effect of sudden insight on immediate sense of agency and motivation and coping.

“…The ACC, as part of the salience network, is one of the brain areas that is most consistently associated with insight solutions in general (see both meta-analyses by Sprugnoli et al, 2017;Dietrich & Kanso, 2010). Note, there are other regions like the right anterior temporal gyrus (Tik et al, 2018;Jung-Beeman et al, 2004) as well as the medial temporal lobe including the hippocampus and the amygdala that have also been associated with insight problem solving (Kizilirmak et al, 2016(Kizilirmak et al, & 2019Becker et al, 2020b;Ludmer et al, 2011). While the ACC has been observed to facilitate insight by positive affect (Subramaniam et al, 2009), it has additionally been identified in the context of restructuring and interpreted as a mediator of breaking one"s mental set to form novel task-related associations (Zhao et al, 2013;Luo et al 2004b, Wu et al, 2013.…”

Verbal insight revisited — dissociable neurocognitive processes underlying solutions accompanied by an AHA! experience with and without prior restructuring

In this article, we investigate insight problem solving by exploring the subjective AHA! experience as a function of restructuring of a problem. It has long been assumed that the AHA! experience is the direct consequence of restructuring. However, is this assumption justified? We will argue that a) the AHA! experience does not always result from prior restructuring and that b) solutions with accompanied AHA! do not underlie a single neurocognitive process. In this regard, we use a modified compound remote associates (CRA) paradigm designed to experimentally dissociate restructuring from the AHA! experience. Results indicate that solutions accompanied by an AHA! are often found also in absence of restructuring. This finding is explained by proposing distinct CRA solution processes that differentiate between AHA! solutions with and without restructuring. We predict that solutions with accompanied AHA! experience differ in their behavioral, neural and eye-tracking related signature as a function of restructuring. The results mostly support these predictions. These findings have implications for insight research: First, by only measuring the subjective AHA! experience especially using CRAs it cannot be implied anymore that restructuring has occurred. Second, it is vital to experimentally separate the different components of insight to better understand its underlying diverse neurocognitive processes.
