9. ,1 HYPOTHESES
1" There is a relationship between the responses of individuals to
Thornton's (1977 )
Rapid Dark Adaptation Test and a '10-Second
Test.
2,
The variation in the perception of the purkinje shift occurs at a
f ixed interval .
3.
There is a relationship in the performance (test times) of adults
and 7-10 year old children in Thornton's (1977) napid Dark
Adaptation Test.
4. The tesb times of adults and children in the 10-Second Test are
related.
9.2 DESIGN
A toLa1 of 4 separaLe experiments were carried out. Experiment I was
designed to see if there was a relationship between the response of
subjects in the Rapid Dark Adaptation Test (Thornton, 1977 )
and in a
1O-second Test (modification of the Rapid Dark Àdaptation Test) "
Experiment II was designed to quantitate fluctuations in the perception
of the purkinje shift during dark adaptation; Experiment iiI
lvas
designed to test the application of the Rapid Dark AdaptaLion Test and
