Note. The far left column (BLK) lists the designation assigned to the block and is described in the text. Subsequent columns indicate the sample and comparison pairs used during the blocks that correspond to the different vocation-based equivalence classes. No Sa or Co+ listed in a row indicates that the Sa and Co+ were identical to those presented in the preceding row. Each trial within a block was presented four times regardless of block type or, within training trials, during feedback reduction.
