The prediction that orienting response (OR) reinstatement
is negatively related to the measure of common features,
shared by the stimulus input and representations of preceding
events, and positively related to the measure of their
distinctive features, was examined. A nonsignificant test
stimulus (TS) was presented after nine repetitions of a
standard stimulus (SS), followed by two additional repetitions
of SS. TS was created by either substituting 0, 1, or 2
components of SS (Experiment 1), or by either adding or
deleting 0, 1, or 2 components of SS (Experiment 2). Skin
conductance changes to TS (OR reinstatement) and the subsequent
SS (dishabituation) were used as dependent measures. The
results of Experiment 1 supported the prediction that substituting
components of neutral stimuli affects OR reinstatement,
with a larger effect for between-categories than within-categories
substitution. Experiment 2 demonstrated that adding and
deleting components similarly affects OR reinstatement.
