Task analysis for perceptual learning, specificity, and reweighting versus representational enhancement. (A) distinct representation and response structures; (B) distinct representations but shared task structures; (C) shared representations, but independent task structures; and (D) shared representations and shared task structures. Only scenarios C and D provide an opportunity to distinguish reweighting and representation change. Modified from Petrov, Dosher, & Lu (2005), Figure 1.
