Rater familiarity in simulation validity studies McCormick, Carroll Owen


Previous research on photographic simulation validity is reviewed. Evidence supporting simulation validity is found, but methodological flaws seriously compromise the results of many of the studies. In the present study 408 University of British Columbia undergraduates rated the affective quality of two building interiors, using actual site, color slide, and written description media. Groups rating each site at each medium were equally represented by familiar and unfamiliar raters. The hypothesis that compensating efects of rater familiarity with stimulus sites produce results that are misinterpreted as supportive of simulation validity was tested. Results show that valid ratings of color slides were obtained, but results that appear supportive of simulation validity can be confounded with rater familiarity effects and building prototypicality.
