Posterior-occipital P100. While the right hemisphere (right panel) showed no significant effects, the P100 amplitude in the left hemisphere (left panel) was significantly greater for the affording versus the control object during both low load and high load. Notably, there was no difference in P100 amplitude between low and high load, nor was there an interaction between Load and Object. This demonstrates early visual processing for the affording object was selective to the contralateral hemisphere (i.e., the right handled cup in the left hemisphere) and that early sensory perception was not significantly different between high and low WM load.
