Figure 1.
A distractor appeared above or below fixation at random and was either the same as (compatible) or different than (incompatible) a subsequent central target. The distractor and the target were both either upright or inverted, depending on the version. Participants identified the central target on all trials by pressing one of two buttons.
Figure 2.
For each version (non-face objects, upright faces, and inverted faces), the size of the compatibility effect in milliseconds for each distractor-target SOA.
The compatibility effect equals response latencies on incompatible trials minus response latencies on compatible trials.
