| This study is based on the Mednick's remote association theory and combines with the composite remote association test compiled by the foreign scholars and the remote association test by the Taiwanese scholars who compile the Chinese Compound Remote Associates Test. Besides, the study adopts the Abbreviated Torrance Test for Adults as the test criterion. It comprises of the three seemingly irrelevant character (board, hole, color), and it requires the tester to find out the fourth character, then makes it forms into the legal word (blackboard, black hole, black) with the former three characters. Moreover, seventy-four undergraduates participate in this test which shows that its inner reliability is good and the Chinese Compound Remote Associates Test can be the materials of the remote association test.Some pictures used in the study were chosen from the International Affective Picture System (IAPS)----intensity to motivational dimension (high, low) and direction to motivational dimension (approaching, avoiding). Each picture was being measured by the Likert 9 point scale on the three dimensions of valence, arousal and motivation approach. The results indicate that the scores of pictures of each group in the motivational dimensions of emotion are strikingly different(p<0.01). Counting from the highest to lowest is that the high and low motivation motivational emotional pictures of emotional pictures, the low motivation of avoiding emotional pictures, and the high motivation to avoid emotional pictures. Meanwhile, the Late Positive Potential(LPP) in the left prefrontal area evoked by pictures of each group shows that the LPP amplitude evoked by the picture of high levels of approach avoidance motivation is significantly higher than that of low motivation approach avoidance dimension strength(p<0.01). The above results show that each group of pictures can induce the corresponding emotion which can be the Inducing stimulation of the different motivational dimensions of emotion.Then, we investigate the influence of the different motivational dimensions on the remote association test in the Late Positive Potential (LPP). The direction and strength of the emotional motivation dimensions are independent variables. The ACC and RT of the remote association test amplitude and the latency of the N400 evoked by the Remote Associates Test are the dependent variables. The 2 (emotional motivation dimension: approach and avoidance)* 2 (emotional motivation:high and low) within subjects design is used in the test. And twenty-five undergraduates (10 males and 15 females) participate in the experiment.The results show that the main effect of the N400 evoked by the remote associates test and its accuracy under the different motivational dimension of emotion is so striking. The accuracy of the RAT under the condition of low motivation (approach, avoiding) emotional is dramatically higher than that of high motivation approach (approach, avoiding) conditions (p<0.01). Thus, it proves that the low intensity motivational dimensions of emotion have a huge positive impact on the process of the remote association. The N400 evoked by the remote associates test under the condition of the low motivation (approach, avoiding) is significantly higher than which in high motivation (approach, avoiding) conditions (p<0.01). So it proves that the individuals under the condition of the low motivation approach (avoiding) can increase its attention span while searching in the semantic network. In this process, its cognitive conflict becomes low, and later, it promotes the formation of the novelty links.Combining previous researches, we can conclude that the low motivation of emotions is beneficial to the settlement of the remoter associate problems. Compared with the high motivation of emotions, the low motivation of emotions can help the individuals to broaden its attention span in the semantic network and makes the remoter associate problems solved easily. |
