Table 1.

The four experimental stimulus conditions (C, CS, IS, and ICS) used in Change trials are depicted in the rows, and each representational dimension investigated (identity, shape, and case) are depicted in the columns.

For each condition (rows), the letter dimension which changes with the fourth stimulus is indicated in red, unchanged dimensions are depicted in blue. For each representational dimension (columns), the grouping of conditions used to test for sensitivity to that dimension is represented by the contrast between red and blue cells (C, case; S, shape and I, identity).
