AGE AND BEHAVIOR: PROCESSING SENSE INFORMATION - SEQUENTIAL INTEGRATION
If a person responds to a stimulus and then responds to a second one shortly afterward, the second response is often different from the first one, even if the two stimuli are identical. One theory explaining this is that the first stimulus, in its neural representation, must be "cleared through the nervous system" before the second stimulus can be responded to as was the first one. Before the nerve impulses are so cleared through, before neural transmission is complete, the person is not optimally ready to process the input of the second stimulus. The trace of the first stimulus persists, so to speak, leaving the responder either relatively refractory to subsequent stimulation or, more often, responsive but in a different way.
As a theory or a model, much data can be explained by this notion of stimulus persistence. As a theory or a model, there is reason to believe that stimulus traces persist longer in the nervous systems of old people than of young ones. For example, Welford (1969) referred to a study by Jeeves in which speed of response was measured to each of two stimuli separated by brief time intervals. The task was a four-choice reaction task. When the two stimuli were very close in time, the response to the second stimulus was slower than to the first one. Welford reported that for adults aged 18-33 years, it was not until about 300 milliseconds elapsed between stimulus-response sequences that the response to the second stimulus was as fast as to the first. But for older adults aged 58-71 years, about 500 milliseconds were necessary for this to be the case. The inference here is that the neural impulses of the first stimulus, together with those of the associated response, persisted longer in the older group than in the younger, and left them less prepared for the second stimulus.
This idea of stimulus persistence is a theory or a model more than it is a fact, but many facts seemed to fit the model. For this reason, the model is useful. The fit of perception data to the model was suggested by Axelrod (1963) and was expressed succinctly in a later report:
‘In the senescent nervous system, there may be an increased persistence of the activity evoked by a stimulus, i.e. . . . the rate of recovery from the short-term effects of stimulation may be slowed. On the assumption that perception of the second stimulus as a discrete event depends on the degree to which the neural effects of the first have subsided, the poorer temporal resolution in senescence would then follow (Axelrod, Thompson, and Cohen, 1968).
The concept of stimulus persistence also receives support in the psychophysiological literature. Mundy-Castle (1953) observed that EEG aftereffect activity to photic stimulation is more enduring among older adults than among younger ones. This physiological support, however, must be regarded as tentative because stimulus persistence theory is applied here in post hoc fashion, i.e., the study was not done to test the theory, but the theory was used after the fact to explain the data.’
