Abstract
Response speeds of eight monkeys (Macaca mulatta) were recorded as a measure of the strength of stimulus trace in remembering 1‐ to 4‐light displays in a 4 × 4 matrix of translucent panels. The age of the animals, the length of the period between the warning signal and the stimulus, the duration of the delay between presenting the stimulus and allowing the animal to respond, and the complexity of the stimulus pattern were varied. Speed decreased for longer poststimulus delays and older subjects. The length of the foreperiod had a complex effect on response speed, and the display light position or pattern complexity had no reliable effect. These findings were contrasted with monkey memory measured by correct responses.
