Effect Of Attention On Change Blindness In Affective Priming

Using the A-ISI-A-ISI-A’-ISI-A’-ISI flicker paradigm, studied of emotional start-up conditions, the attention to the scope of change blindness. Experimental groups come from college students, the total was36, they were17-32years old, the average age was22.65years old, when the SOA was300ms, after again assessed to ensure that the amount of information the same positive and negative emotional pictures as Affective Priming materials, selection black solid small rectangular matrix as the change blindness material, and joined the pre-cues, to study the sensitivity of the test on the change in direction. Experiment II trial groups come from college students, a total of18between the ages of19-23years old, the average age is20years old, whether had or not cues,the ring that center filled with50%gray and center diameterd as lightness change blindness material, investigated the sensitivity of the change in lightness.The first experiment used emotions (positive/negative)×attention to the range of (large/small) two-factor repeated measurement experimental design. The range of emotions and attention were within variable emotional start and pay attention to the scope of the order of the two types of random balance test may appear to control practice effects and fatigue effects, reducd the maximum chance of guessing.The second experiment used a single factor within-subject design. Factors for the type of cues, there were three levels:large boxes, small boxes, and silent clues. Lightness of the ring to change the position that appears also used a random manner, to reduce the subjects guess factors.The results show that:(1) Detection of changes in the direction of the emotions start impacted. Different emotional state change detection reaction was different; in a positive emotional state change detection reaction was faster than in a negative emotional state.(2) When the detection reaction of the average change in the small range attention cues than under a wide range of attention cues to be fast. (3) Emotional start work was expanded or reduced attention spans. In the range of large prompt, subjects in a positive mood state, thinking, active range of attention had also been expanded faster discovery around the characterization of different subjects while in a state of negative emotions, attention resources were occupied the time required to complete the change detection task as extended; small note range, in a negative state was the pilot’s attention fixed in the center of the matrix, this test of attention than be in a positive state, in small changes within the range was also more easily be found.(4) In the present experimental conditions, the detection of changes in brightness was automatically processed, the cue had no influence. The two basic attributes of the stimuli belonging to different cognitive processes, they were independent.
