Abstract
The present study attempted to replicate the E-bias effect using Rosenthal’s (1966) basic paradigm, examine the relationship between E-bias and Ss’ perception of Es’ expectancies, and evaluate the E-bias effect in relation to a no-expectancy control group. Results failed to demonstrate the E-bias effect, although Ss’ judgments of Es’ expectancies were related to the three different treatment groups. The present findings are discussed briefly in terms of Barber & Silver’s (in press) recent review of this area.
