of the objects I observed in class was the Light Discrimination Dial,
which is used to determine light intensity. On this instrument there are
two light stimuli which both have a diameter of 1.375". The procedure
for using this instrument, is to have the subject(s) look at both of the
light stimuli as the examiner is either increasing or decreasing the
light intensity. Afterward, the subject(s) is responsible for
identifying whether or not the light intensity was greater, less, or
equal to the original brightness. Researchers have said that this tool
demonstrates several psycho-physical methods, one being constant
stimuli, meaning the light intensity may or may not vary based on
the length of time the subject had been staring into the light stimuli.
This to me could be used to help explain and display convergence, based
on how long the subject was looking into the light stimuli as well as
how intense the light actually was.
The psychology of Perception involves the interaction of our senses and our conscious mind. Perception is involved in every aspect of our lives as we make decisions and judgments based on what we experience. If you study diligently you will leave this course with a broad understanding of sensation and perception. From this general understanding you will be able to further investigate areas of interest by means of literature review and research on specific topics.
