Predictions for different accounts underlying the diminished affordance during high WM load from Experiment 1. A, For the sustained suppression account, suppression in M1 occurs when WM resources are engaged. It predicts greater LICI over M1 for high versus low load both before and after the presentations of the object. B, For the proactive suppression account, there is greater motor suppression during high load to reduce the potentially distracting influence of the task-irrelevant object. It predicts greater LICI over M1 for high versus low load only before the object is presented because it is no longer necessary following the object. C, For the late attention account, the diminished affordance during high load is due to reduced attention during the later stages of object processing. It predicts no differences in LICI over M1 for high versus low load.
