Rapid Dark Adaptation Test and the'1O-Second Test. The mean time taken
to complete Thornton's RDAT was 366162 second (6.1 minutes). This test
time was increased by about one minute compared to that of adults (307.6
second) reported in day-1 of Experiment I. The difference in time could
have been due to differences in understanding and applying the series of
testing instructions involved in the testing procedure. The instruc-

As observed in adults, there were no significant differences between
trial II and trial III. Test times were not dependenl on the trial
which indicated that Thornton's RDÀT was replicated over the two trials
by these children. There was a significant person effect observed for
children. The time taken to complete the test was dependent on which
child completed the test (p
