Description:
In order to probe the internal organization of visual temporary memory, systematic experiments were performed in which the subjects had to memorize a series of 2-5 images then pass recognition tests, either in all possible testing permutations, (in the case of 2-4 images) or in 20 selected permutations (in the case of 5 images). Over 300,000 tests were performed, generating more than 40,000 errors. The error-rates were found to follow simple rules. Both the 3 and the 4 images results are compatible with the presence of only four typical accuracy levels. On the other hand, the reaction time (RT) results revealed surprisingly rich patterns. The RT for recognizing image i at testing stage t>1 depends upon which image (j) was tested just before. The ranking of the RTs for (j,i) couples evolves from one testing stage to the next. It is proposed that these RTs reflect, in part, the time needed to localize the trace in memory of a given image, starting from the position at which the previous test occurred. If this assumption is correct, the results of this study are providing a picture of the configurations formed by memorized items in the visual temporary store. A hypothetical minimal model, involving several rows of slots on a triangular mesh is proposed to account for the structures in both the error-rates and the RT results.
