And because that response is incompatible with the required response for the probe display, performance is impaired. The best evidence for this model is the finding that on error trials, incorrect repetitions of the prime display target are over-represented in the ignored repetition condition relative to control. "
This sentence is unclear. Maybe it can be expanded using the example in Figure 2.
