Learning slopes from regressions of (log10) contrast threshold on (log10) practice block, including the two pretest blocks in the first stage and excluding the two pretest blocks in the second stage. Transfer is tested as a nested F on regressions with and without an independent intercept for the pretest stimuli in the second stage, with df = 1,21. P < .1; *, P < .05; **, P < .01; ns, nonsignificant.
