Yet none of the surveyed research has systematically controlled and examined the…

In order to examine the effects of manipulating image size (i.e., relative size) and body type of speakers in a television context on source credibility and interpersonal attraction, a study was conducted at Illinois State University during the spring of 1973.

The purpose of this study was to examine the effects of two nonverbal visual variables (camera angle and image size) on variables developed in a nonmediated context (source credibility and interpersonal attraction). Camera angle and image size were manipulated in eight video taped television newscasts which were subsequently presented to eight…

If they do differ, what effect do these differences have on receiver's attitude toward the object of that network coverage? Phase 1 of the study examined the speeches of Ted Kennedy…

The purposes of this paper are to compile and describe the published empirical studies that have examined nonverbal visual production variables, to offer a critique of the lines of inquiry, and to suggest some areas for continued research. The studies are presented in two major sections: intravisual and intermedia. The intravisual section…
