'Verbal overshadowing' refers to the phenomenon whereby the verbal reporting of a visual memory of a face interferes with subsequent visual recognition of that face. Schooler (2002)[1] suggested that verbalization causes a shift from a holistic/global processing orientation towards a more analytic/local processing orientation that is detrimental to face recognition. The present research investigated whether this processing shift occurs or not by assessing performance of Navon task following face recognition task, interposing verbalization between encoding stage and retrieval stage. The face recognition task showed the verbal overshadowing effect. In the Navon task, while non-verbalization group showed global precedence, verbalization group showed local precedence. This results imply that the cause of verbal overshadowing effect is a processing shift induced by verbalization.

The implicit association test (IAT) measures implicit attitudes of participants and is regarded as an effective method for expecting future behaviors. Based on the IAT, this study aimed to answer the question, whether implicit attitudes of an individual about creativity have any kinds of impact on global perception, which might be important for a creative process. In the experiment, participants were presented words, which were associated with one of four categories, while one attitude category (creativity /practicality) and one evaluative category (good/bad) were always paired together either on the left side or on the right side of the computer screen. After completing the IAT test, participants were led to fill out a questionnaire to assess explicit attitudes toward creativity and practicality. Then they conducted the navon task, in which they had to find one of two letters, 'F' or 'H', which were presented either as a local form or as a global form. Finally, the participants had to write down as many untypical functions of an object as possible. The results showed that not the scores of explicit attitude scores but the IAT scores correlated with the reaction time of global perception. The global perception was faster in the participants with the low IAT scores than the local perception. Compared to this, the global perception benefits disappeared in the participants with the high IAT scores. Additionally, more creative ideas about the functions of the object were listed in the group with the lower IAT scores. Implications of the role of implicit attitudes about creative processes are discussed.
