“…Except for a heart rate study by Marinelli (1974) that revealed only trends in the predicted direction, the other eight disability studies found psychophysiological reactivity to be a reliable indicator of emotional discomfort in the presence of disabled individuals introduced either i-n vivo or pictorially. The psychophysiological measures used in these studies included electrodermal activity (Heinemann et al, 1981;Kleck et al, 1966;Wesolowski & Deichmann, 1980;Zych & Bolton, 1972), heart rate (Gargiulo & Yonker, 1983;Marinelli & Kelz, 1973;Wesolowski & Deichmann, 1980), or the PSE (Vander Kolk, 1976aKolk, , 1976bKolk, ,4 1977a).…”
