Visual dissociation occurs when a visual marker from one display in a
rapidly presented sequence (e.g., 9 item/sec) is perceived as having o
ccurred in a temporally adjacent display. Three experiments that evalu
ated the application of computer graphics technology to study this phe
nomenon with digitized color photographs are reported. The primary con
cern was that visible phosphor persistence might artificially increase
the frequency of integration errors. In Experiment 1, visible phospho
r persistence was assessed using a multiple-repetition shutter test to
determine which stimulus conditions did not yield reportable persiste
nce. On the basis of these results, visual dissociation performance wh
en the same color photographs were presented using mechanical 16-mm pr
ojection (as in previous research) and when they were presented on a c
omputer monitor were compared in Experiments 2 and 3. The results supp
orted computer application, in that computer presentation yielded the
same pattern of errors and accuracy levels as did research using mecha
nical projection.
