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.
