Abstract: | Arrays of 12 fragmentary letters were followed, at various intervals, by one randomly selected complementary letter fragment. On half the trials a partial-report cue (a vertical bar-marker) coincided with the second completion fragment. In Experiment 1 subjects fixated the centre of the to-be-identified letter location, whereas in Experiment 2 subjects fixated the centre of the array. In Experiment 1, the degree of integration and time between successive fragments were inversely related. Integration of fragmentary letters in Experiment 2, however, was uniformly low in the experimental and guessing control conditions. The results were discussed in terms of recent non-traditional accounts of iconic storage that emphasize post-categorical processing. |
