INTRODUCTION A lot of studies showed that creaTvity, defined as a valuable ability to generate a new and useful idea, can be constrained by fixaTon effects. While the !. automaTcity of knowledge usually leads to an adapTve mechanism allowing to answer quickly and correctly when confronted to known situaTons, someTmes the spontaneous acTvaTon of knowledge may be used in an inappropriate and counterproducTve way and constrain the exploraTon of other soluTons (Duncker, 1945; Smith et Ward, 1993 ; CassoH et al., 2016). Therefore, if “to think outside the box, one must forget what is inside the box” (Storm and Angello, 2010), the quesTon that needs to be invesTgated is: “how to think outside the box? ”. Even if some theories and experiments defended that creaTvity is exclusively related to automaTc mechanisms (MarTndale, 1999), other recent behavioral and neurocogniTve experiments such as the dual system theory of creaTvity (CassoH et al., 2016) support the implicaTon of cogniTve inhibiTon (Benedek et al., 2014 ; CassoH et al., METHOD 2016). Then, the present study aim for the first Tme to idenTfy neural bases of these mechanisms.. PARTICIPANTS . PHYSIOLOGY. 21 young adults (11 females, 10 men, m = 20,33, SD = 2,18), right handed.

As expected, priming the classical use of an object before the generaTon of creaTve alternaTve uses of the object impeded parTcipants’ performances in terms of remoteness. In the control condiTon, while the frontal alpha synchronizaTon was maintained across all successive Tme windows in parTcipants with high remoteness scores, it decreased in parTcipants with low remoteness scores. In the FixaTon Priming condiTon, while all parTcipants maintained frontal alpha synchronizaTon throughout the period preceding their answer, only parTcipants with high remoteness scores maintained alpha synchronizaTon in the temporo-parietal regions. Then, our findings provide addiTonal evidence for the role of cogniTve control in creaTve ideaTon, while suggesTng that cogniTve control alone is not enough to generate new ideas.. 1 2 3 4 5 6 7 8 9. 1 2 3 4 5 6 7 8 9.
