short-run Conceptual Memory for Pictures
Mary C. Potter Massachusetts nominate of Technology
Three converging procedures were used to determine whether pictures presented in a rapid sequence at rates comparable to pump fixations are understood and then quickly forgotten. In dickens experiments, sequences of 16 color photographs were presented at rates of 113, 167, 250, or 333 millisecond per picture. In one group, subjects were given an immediate test of fruition memory for the pictures and in other groups they searched for a target picture. eve when the target had only been specified by a call (e..g., a boat) detection of a target was strikingly fantabulous to recognition memory. Detection was slightly but significantly purify for pictured than named targets. In a third experiment pictures were presented for 50, 70, 90, or 120 msec preceded and followed by a visual cloak; at 120 msec recognition memory was as accurate as detection had been.
The results, taken together with those in 1969 of Potter and Levy for slower rates of sequential presentation, signify that on the average a scene is understood and so becomes immune to ordinary visual masking within astir(predicate) 100 msec but requires about 300 msec of further processing before the memory representation is rebarbative to conceptual masking from a following picture. Possible functions of a short-term conceptual memory, such as the control of midriff fixations, are discussed.
As we glance around, we make a serial of gotten or are simply not identified in the rapid saccades that present a new scene to stolon place. A verbal item may be recognized, the retina both 300 msec or so. New scenes held briefly in short-term memory, and then â€"for example, picturesâ€"are remarkably forgotten. The experiments reported in this easy to remember when seen for 1 sec or article...If you pauperization to get a full essay, order it on our website: Ordercustompaper.com
