Appearance results (Experiment 1, Phase 2). We show results pooled across 10 observers. (A) Precue trials: The psychometric function shifts toward lower test contrast when the test is cued, and toward higher test contrast when the standard is cued, indicating that transient attention increases the apparent contrast of the cued stimulus. (B) Postcue trials: The psychometric functions for test-cued and standard-cued conditions are not statistically different from the neutral cue condition. Error bars are ±1 SEM.
