Percent correct naming by 48 subjects
participated in the second 4AFC experiment. After each trial in the
first block, a 4AFC test was administrated. For images that could not
be named when initially shown, accuracy on the subsequent 4AFC test was
31.6%. Images correctly named were always responded to correctly on
the 4AFC test. Again, repeating the same image within the same quadrant
improved identification markedly, whereas when objects were translated
to a different quadrant naming accuracy was only slightly higher than
that for control images in the second block. When we consider only the
objects that were not identified correctly in block 1, the
identification rates in the second block were 42.4% for the
Within Quadrant condition, and 27.5% for the Between
Quadrants condition. This replicates the results of experiment
