| Abstract: | Two experiments are reported in which changes in Es' (N = 11) experimental hypotheses led to changes in the data they obtained from their Ss-(N = 87). Monitoring of Es' experimental procedure sometimes led to an increase, sometimes to a decrease in the effects of Es' expectancies. For both experiments male. Es significantly exerted the expected biasing effects upon both their male and female Ss. Female Es similarly influenced their female Ss but obtained data from their male Ss significantly opposite to the direction of their hypotheses. |
