Experiencing positive emotions signals safety, influences thoughts, and expands the attention span. They encourage the individual to think flexibly and creatively and solve problems. Furthermore, experiencing positive emotions accumulates over time and builds long-term psychological, physical, and social resources. The aforementioned broaden and build are the basis of the theory of Barbara Fredrickson (1998, 2004). The connection between thoughts and moods has often been the subject of research in psychology. In this paper, we focus on the effect of positive mood on divergent and creative thinking and convergent and mathematical-logical thinking. This study aimed to examine the effect of induced mood on the stated opinion. According to the assumptions of broaden and build theory, it was expected that a positive mood would increase the effect of thinking that was tested by verbal and numerical tests designed for the purpose of this research. The results of testing the effect of positive mood on divergent thinking show that there are no differences in word and letter generation between positive and neutral individuals. A test of generating words of six or more letters showed that participants in a positive mood performed three times higher after listening to positive music compared with their performance before listening to music. The results show that the performance of generating words of six or more letters in the group that listened to neutral music did not change after the manipulation. The results of testing the effect of positive mood on convergent thinking showed that participants who listened to positive music achieved better performance on mathematical tasks than participants who listened to neutral music.
