Definition of Stimulus Trace
Stimulus trace is the internal trace of the environmental stimulus that can persist for some time after the external stimulus has ceased. Stimulus trace can serve as a signal for response, or as a carrier of perceptual data from which information is extracted and reported.
It is different from memory trace, or habit.
Physiological evidence for stimulus trace is documented by Lorente De No (1938), Burns (1951), and Evans and Robertson (1965). Stimulus trace as a behavioral construct has been used by Pavlov (1927, pp. 42-43), Hull et al. (1940), Hull (1943, 1951, 1952), Spence (1956, pp. 94-95), Konorski (1961), and Adams (1964, p. 185).
