Opponent Process Theory

I developed an interactive computer program that allows one to demonstrate and experiment with various phenomena in visual perception using IBM-compatible computers. The program contains modules for demonstrating the color afterimage, the cafe illusion, additive color mixing and the opponent-process theory of color vision, the glowing axes illusion, the Hermann grid, the McCollough effect, the motion aftereffect, the neon illusion, and simultaneous contrast. The user has considerable control over the stimuli making up the image and can manipulate the variables that contribute to the perception of the effect. The program can be used far classroom demonstrations and student laboratory projects.

Perceptual Systems

Three factors that have transformed perceptual research in the last fifty years are the digital computer, single-unit electrophysiology, and molecular biology. Amongst the developments in which members of the Experimental Psychology Society have been central are: the recognition of the role of optic flow in spatial vision; the demonstration that our perceptual systems contain parallel pathways extracting different information from the sensory array; the identification of specific detectors that can be selectively adapted in psychophysical experiments; and the transfer of the concepts of fourier analysis from audition to vision. The history of Opponent Process Theory offers an example where experimental psychologists have been misled by too simple an interpretation of physiological recordings.

Theory Of Motivation

Previous attempts to show that death is sometimes postponed until after an important social occasion have focused on the relationship between birthdates and deathdates. The present research uses Christmas as the focal social event. Study I, which involved the number of obituaries published in a major metropolitan newspaper during the eight weeks centering on Christmas, showed a significant death dip immediately prior to Christmas and a significant death surge immediately thereafter. Study II, which was based on the actual death dates of eminent Americans, yielded the same general pattern of results and also revealed that the post-Christmas upswing was significant only in the case of people who had surpassed the sample's median age. Study II, which involved a day-by-day analysis, showed that the post-holiday increase was very abrupt. All of these findings are fully consistent with Solomon and Corbit's opponent process theory of motivation.
