Mean compatibility effect (incompatible minus compatible) by condition of search type (fixed difficulty vs. mixed difficulty) and distractor difficulty (easy vs. difficult). Upper panel: Mean effect of reaction times (in milliseconds). Lower panel: Mean effect on error rates (in percentage).
Table 2
Mean RTs (in milliseconds) and accuracy rates (in percentage) on invalid-cue trials in Experiment 1 by conditions of cue-target compatibility, cued-distractor difficulty and search type. The numbers between square brackets represent the standard errors.
