Fig. 4From: Great expectations: minor differences in initial instructions have a major impact on visual search in the absence of feedbackAnalysis of the significant effects of high-expectation (blue) versus low-expectation (orange) on hit rate and response time as a function of experimental block to examine the evolution of the effect over time. The difference between groups was present at the beginning of the experiment and remained present over the course of the experiment for a easy single-target hit rate, b hard single-target hit rate, and c hard single-target response time. The group x block interaction effect was not significant for all three measures. Error bars depict the S.E.MBack to article page
