Abstract
Effects of auditory distraction on the time-estimation by verbal estimation method
S.N. Rai
To study the effects of auditory distraction on time estimation by the verbal estimation method, 20 Ss of both the sexes were divided into 2 groups: 10 Ss for `SQ' group (stimulus in quiet) and 10 Ss for `SS' group (stimulus in sound). `SQ' group obtained 15, 30, 60 and 120 sec, stimulus intervals, five times each in random order under normal condition (without distraction) while `SS' group received the same stimulus intervals with continuous sound of 1250 c.p.s. The results showed: (a) `SQ' and `SS' of verbal estimation method have differential effects on time estimation for all the stimulus intervals, (b) A tendency of over estimation is found for `SQ' and `SS' both conditions, but `SS' condition yields more over estimation of all the stimulus intervals in comparison to `SQ' condition, (c) For both `SQ' and `SS' conditions repeated trials have significant differential effects on time estimation, i.e., increase in trial number, decreases the magnitude of errors (overestimation), (d) `SQ' and `SS' do not interact with repeated trials in a significant manner.
