Abstract

The number of articles concerned with contingency assessment has increased steadily sincethe pioneering research by Herbert Jenkins and colleagues in 1965. Around the same timeFergus Craik argued that aging effects on performance should be analyzed within apsychophysical framework. Surprisingly, there have been few reports about the effect of ageon contingency assessment, and none of these have incorporated a psychophysical approach.We will present research demonstrating the utility of applying psychophysical methodology tounderstanding differences in contingency assessment seen in older participants (seniors)compared with university students.
