Figure 4.
Orientation discrimination performance (accuracy) for trials on which the observers chose the standard stimulus. Performance in the (A) main and (B) control experiments is graphed as a function of cuing condition: cued (i.e., standard cued), uncued (i.e., test cued), or neutral (i.e., neither stimulus cued). Error bars represent standard errors of the means, calculated using the method of Loftus and Masson (1994). The percentage of trials on which the observers selected the standard stimulus in each condition is indicated. ISI, interstimulus interval. *p < .05.
