AN EXPERIMENTAL STUDY OF AUDITORY-VISUAL M0DALITY EFFECT IN TIME JUDGEMENT
Huang Xiting;Zheng Yun Institute of Psychology, Southwest China Normal University, Chongqing
Two intervals were presented at the same time auditorily or visually.Following the presentation, the subject was given randomly one of the twointervals, and was asked to reproduce it immediately orafter a delay of 5sec.The results showed that: (1) In the short time interval condition (1sec.,1.5sec., 2sec.),the reproduction is more accurate for audition rather than vision,and for audition,deley has little effect on temporal information coding. How-ever, in the Iong interval condition (10sec., 11sec., 12sec.), the subject'spreformance was indistinguishable whether the intervals were presented audi-torily or visually. (2) The source of the modality effects is not sensory storedbut memory. (3) Positive time-order-error often occurred in the judgement off-short time interval,negative time-order-error was more likely to occur in longtime interval.
