Three induced affect (IA) studies are reported. Their goal was the development of a methodology for inducing and quantifying specific affective states in a controlled setting, with the ultimate purpose of making the detailed study of affective states more feasible. Euphoric by moderate autonomic activation were elicited with cue manipulation in the IA paradigm in subjects differing in level of adjustment. Physiological (pulse and respiration rate) and self-report measures were employed, and these proved sensitive to transitory changes in euphoric and dysphoric states. Suggestions are offered for the application of these methods. (KS)
