“…For example, research efforts within the framework of information-theory (Attneave, 1955; LTM Processes in Visuo-spatial WM 5 Schnore & Partington, 1967) found recall of dot-in-matrix patterns to be a linear function of the degree of symmetry manifest in the patterns. Research on complexity judgements of matrix patterns has in fact shown that the concept of complexity is determined by both a quantitative and a structural factor (Chipman, 1977;Ichikawa, 1985).…”

Several studies have shown that the capacity of visuo-spatial working memory is limited by complexity. Using a variant of the Corsi blocks task, this paper investigated the effect of complexity of the to-be-remembered path on visuo-spatial memory span. Redundancy was determined by three Gestalt principles: symmetry, repetition and continuation. Experiment 1 revealed an effect of path complexity. The subsequent experiments explored whether the superiority for recall of structured over complex paths can be attributed solely to the operation of visuo-spatial working memory, or whether it also reflects the use of long-term knowledge.Experiment 2 demonstrated that the effect of complexity remained, even when the mechanisms for visuo-spatial coding were removed by a secondary visuo-spatial task. In Experiments 3 and 4 subjects were trained in the recall of complex paths. This led to the creation of long-term memory representations for these paths, as shown by an improvement in their span, and a concomitant lack of transfer to new paths. Finally, Experiment 5 showed that one prior repetition of a complex path was sufficient to produce specific and long-term learning effects. These results point to the involvement of long-term memory processes in the temporary retention of visuo-spatial material for which representations exist in long-term memory. They also suggest that the effect of complexity may provide a tractable technique for investigating the mechanisms underlying the limits of visuo-spatial short-term storage.LTM Processes in Visuo-spatial WM 3

“…The notion of this system has arisen from the work of Phillips and his colleagues. The paradigm they have developed stems originally from Schnore and Partington (1967) and subsequently employed in various forms by Yuille and Ternes (1975) among others (e.g., Phillips and Baddeley, 1971;Adamowicz and Hudson, 1978).…”

“…Several of these studies (e.g., Attneave, 1955;Bear, 1973;Schnore & Partington, 1967) have shown that the location of the local units can be remembered or predicted better with stimuli that are structurally redundant (i.e., good patterns) than with stimuli that are not (i.e., poor patterns). All of these studies have used stimuli such as dot patterns that differ only globally in the relative location of the local units (i.e., not in the number of absolute locations).…”

In two experiments, the accuracy with which subjects detected a conjunction of features was examined as a function of the spacing between items and the goodness of the axis along which they were located. In each array, two items were arranged along a vertical, a horizontal, or a diagonal axis. Based on the well-established oblique effect, the vertical and horizontal axes were considered to be good global patterns and the diagonals were considered to be poor. In Experiment I, the two items in an array could be two horizontal lines, two vertical lines, a vertical and a horizontal line, or a plus sign with one of the single lines. In Experiment 2, a positiveand a negative-diagonal line were used as the individual features, and an "X" was used as the conjunction. The results from Experiment 1 indicated that global goodness influenced only the rate of illusory conjunctions, and not of feature errors. lllusory conjunctions of vertical and horizontal line segments were more likely to occur in vertical and horizontal arrangements. The results from Experiment 2 revealed a reversal of the effect of global goodness on the rate of illusory conjunctions: Illusory conjunctions of negative-and positive-diagonal line segments were more likely to occur in diagonal arrangements. The results of both experiments taken together showed the existence of an important and new factor that influences the likelihood that features of shape will be conjoined: the ease with which line segments conjoin when they are translated along their extent toward each other. In both experiments, greater spacing between items produced more feature-identification errors and fewer feature-integration errors than did less spacing.
