Notes:
Stimulus-response specificity and individual-response stereotypy were evaluated during segments of anticipation, stimulation, and recovery. Skin conductance, heart period, respiration period, and blood pressure were measured in 20 normal subjects in response to six stimuli: Sound, Music, Math, Poem, Light, and Cold Pressor. The difference between mean level during each segment and prestimulation, corrected for prestimulus level, was divided by the nonsyste-matic variability of response in order to provide a standard score. Specificity was assessed through the Variable × Stimulus interactions of an analysis of variance and a components of variance analysis, and from a between subject concordance analysis. Stereotypy was inferred from the Variable × Subject interaction of the components analysis and from a between stimuli concordance analysis. Components of variance analyses were also obtained with scores covaried for anticipation level, with a previous method of score standardization, and with stimuli divided into two sets on the basis of response magnitude. Contributions to variance of specificity and stereotypy were shown to vary with method of standardization and type of stimulation.
