Based on a construct termed sensitivity of the nervous |
|
system and the assumption that field-dependence is an |
|
indirect approximation of level of sensitivity, our |
|
previous research has predicted and found field- |
|
independent groups to be superior to field-dependent |
|
groups in color and weight discrimination and in contrast |
|
sensitivity. Here, we re-examine weight judgment using a |
|
more discriminating test and attempt to replicate |
|
previous color results. Seventeen females performed a |
|
weight discrimination task (15 weights, 75-145 grams, in |
|
5-gram increments) on two successive days, three |
|
trials/day, and two trials on the Farnsworth-Munsell 100 |
|
Hue Test. A field-independent group (N=5) Performed |
|
significantly better than a field-dependent group (N=6) |
|
on all trials of both tasks. Although N is small, this is |
|
the fifth replication (in five attempts) of the color |
|
discrimination results and a strong validation of the |
|
previous results with weights. It is suggested that in |
|
studies of sensory discrimination, some of the so-called |
|
random error now must be considered as systematic error, |
|
or bias, and that attention should be given to level of |
|
sensitivity of participants. Keywords: Psychophysiology, |
|
Weight judgment, Color judgment, Females, Sensory |
|
discrimination, Field-dependence, Sensitivity of nervous |
|
system. |
