EFFECTS OF FALSE HR FEEDBACK ON PREFERENCE OF NUDE SLIDES

Abstract

The effects of false feedback regarding subject's heart rate (HR) changes on preference of female nude slides were studied by manipulating his opportunity of self-persuation. Forty male students were divided into four groups. After the first presentation of 10 slides, SS in three groups were falsely informed about the relationship between their HR changes and slides. In Group (I) 5 slides were randomly selected and Ss were informed that their HR had increased to those slides at the first presentation of 10 slides. To the other 5 slides, however, they were told that their HR had not changed. In Group (II) Ss were informed that 5 slides to which HR had increased at the first presentation would be shown, while in Group (III) they were informed that 5 slides to which HR had not changed would be presented. In Group (IV), after the second presentation of 5 slides, Ss were told that those slides had evoked HR-increase. Five slides shown to Group (II), (III), and (IV) were randomly chosen. Results showed that Ss in Group (I), (II), and (III) who had opportunity of self-persuation at the second presentation of the slides evaluated those slides to which false HR-increase information was given as more attractive than those slides to which false HR-constant information was given. These results were not due to the familiarity of those slides presented longer and to actual HR changes.
