A Visual Cognition Test-Based Study on the Choice Blindness Persistence: Impacts of Positive Emotion and Picture Similarity

摘要

Choice blindness is a common psychological phenomenon in many selection tasks. It always presents as a person's failure to notice a mismatch between one's preference and task decision. An important affecting factor of choice blindness is emotion. We studied the impacts of positive emotion and different similarity on the choice blindness based on visual cognitive tests. We designed a 2 (high and low similarity pictures) × 2 (positive emotion and neutral emotion) mixed design. 20 pairs of scenery pictures with different similarities were used as materials and 80 adults were recruited as participants. The results verified the existence of choice blindness in both positive emotion group and neutral emotion group. It was found that significant difference existed in the perception of false feedback between the positive emotion group and neutral emotion group. The female participants in the positive emotion group was more easily perceived the false feedback of low similarity scenery pictures than those female participants in the neutral emotion. In other words, positive emotion had an effect on the choice blindness of the female when they faced the low similarity scenery pictures.
