Social inhibition as a function of observation and recording of performance

In order to compare the relative effects of observation of performance and recording of information about performance on social facilitation/inhibition, 256 college students solved three concept-attainment problems in an orthogonal design. The variables were (a) number of observers (an additional observer or the experimenter alone), (b) videorecording (yes or no), (c) audiorecording (yes or no), (d) task complexity (four, six, eight, or ten total attributes in the problems). Each of videotaping, filming, and audiotaping resulted in poorer performance than the control condition, with no differences between these three recording conditions. The presence of an additional observer had no effect on performance. Pulse measures indicated that the presence of an additional observer increased arousal, but covariance analysis indicated no association between differences in performance and arousal.
