Experimenter-Subject Interaction in Verbal Conditioning: Review of the Literature
This paper reviews investigations of the E-S interaction variable in verbal conditioning. The research is viewed in terms of the constructs of interpersonal attraction and interpersonal influence and is categorized under the headings: (a) experiments in which Es with different physical and personality characteristics are used; (b) experiments in which S's attraction to E is manipulated by S's interaction with him (resultant interpersonal attraction); (c) experiments in which S's attraction to E is manipulated by matching Es with Ss on the basis of psychological test scores; (d) experiments in which S's attraction to E is manipulated by having a collaborator give S information about E (induced interpersonal attraction). Major findings are summarized and suggestions for future research mentioned.
