Abstract
In order to investigate the interaction of experimenter's sex and subject's sex and resultant effects on performance, 60 male and 60 female college students were placed into three groups of 20 males and 20 females each. Each group was tested on a pursuit rotor under one of three conditions: male experimenter presence, female experimenter presence, or no experimenter presence. Five trials of 20-sec. duration each were administered to every subject. Results indicated a significant interaction effect between group gender performance and experimenter gender. However, follow-up comparison tests did not reveal any specific mean differences, and the data were discussed in light of these findings.
