Limited capacity for contour curvature in iconic memory.
We measured the difference threshold for contour curvature in iconic memory by using the cued discrimination method. The study stimulus consisting of 2 to 6 curved contours was briefly presented in the fovea, followed by two lines as cues. Subjects discriminated the curvature of two cued curves. The cue delays were 0 msec. and 300 msec. in Exps. 1 and 2, respectively, and 50 msec. before the st...
متن کاملMemory Capacity and Sentence Processing
The limited capacity of working memory is intrinsic to human sentence processing, and therefore must be addressed by any theory of human sentence processing. This paper gives a theory of garden-path effects and processing overload that is based on simple assumptions about human short term memory capacity.
متن کاملInfants get five stars on iconic memory tests: a partial-report test of 6-month-old infants' iconic memory capacity.
By the late 19th century, tests of adults' short-term visual memory—how much one retains from a briefly presented display—had acquired a familiar character: An alphanumeric array was presented and then removed, and participants were asked to report the items they had seen (Wundt, 1912). These whole-report tests revealed memory capacities of three to four items (Cattell, 1886; Sperling, 1960). H...
متن کاملThe Sensory Components of High-Capacity Iconic Memory and Visual Working Memory
EARLY VISUAL MEMORY CAN BE SPLIT INTO TWO PRIMARY COMPONENTS: a high-capacity, short-lived iconic memory followed by a limited-capacity visual working memory that can last many seconds. Whereas a large number of studies have investigated visual working memory for low-level sensory features, much research on iconic memory has used more "high-level" alphanumeric stimuli such as letters or numbers...
متن کاملIconic memory requires attention
Two experiments investigated whether attention plays a role in iconic memory, employing either a change detection paradigm (Experiment 1) or a partial-report paradigm (Experiment 2). In each experiment, attention was taxed during initial display presentation, focusing the manipulation on consolidation of information into iconic memory, prior to transfer into working memory. Observers were able ...
