| The relationship between emotion and attention has been the focus of psychological research, clarifying the relationship between them is important for promoting the adaptation of human emotions and the distribution of attention. In this paper, using rapid serial visual paradigm, we studied the emotion-induced blindness and emotional attention blink in functional blindness, in order to reveal the effect of valence and arousal of emotional words on these two aspects.A total of two studies were conducted, each of which included two experiments. Subjects were all college students.An experimental study using a 4(emotional words type: positive, negative, neutral, taboo) × 4(delay position: lag1, lag2, lag3, lag8) factorial of the subjects within the design in the experiment a; experiment b using 2(emotional words valence: positive, negative) × 2(emotional words arousal: high, low) × 2(lag position: lag2, lag8) factorial of the subjects in the design, the emotional words as being ignored the key distraction stimulus, the color words as needed to judge the target stimulus, to explore the effect of emotional words, valence and arousal on emotion-induced blindness.The experimental procedures between the second study of experiment a/b and the first study of experiment a/b were almost the same, the difference was that in the second study emotional words that needed to be tried to report the detection of T1(first target), color words was T2(second target), to explore the influence of words, valence and arousal on attentional blink.Through the experimental study, the following results were drawn:First, lag position of c olor words loc ated in d ifferent emotional words had a significant effect on emotion-induced blindness, lag2(SOA: 200ms) position was the maximum of emotion-induced blindness;Second, lag position of color words located in different emotional words had a significant effect on emotional attention blink, lag2(SOA: 200ms) position was the maximum of emotional attention blink;Third, in the study of emotion-induced blindness, there was no "lag1 saving" phenomenon, which was found to be impaired in the lag1 position;Fourth, in t he attentional blink experiment which emotional words were the first tar get T1, lag1 position also appeared the damage to t he target detection of T2 color word, which was not exist "lag1 saving" phenomenon;Fifth, in lag2 position, the valence and arousal of words together affected emotion-induced blindness, negative valence played an antagonistic role, high arousal played a catalytic role;Sixth, in lag2 position, the valence and arousal of words together affected emotional attention blink, negative valence played an antagonistic role, high arousal played a catalytic role. |
