Abstract:
Psychophysical studies of the short-term memory for attributes or dimensions of the visual stimulus that are important in online perceptual processing of visual images - spatial frequency, orientation, contrast, motion - identify a low-level perceptual memory mechanism. This mechanism is located early in the visual processing stream, prior to the structural description system, but beyond the primary visual cortex (V1); it is composed of a series of parallel, special-purpose perceptual mechanisms with independent but limited processing resources. Each mechanism is dedicated to the analysis of a single attribute or dimension of the visual stimulus, and is coupled to a memory store. The evidence for this model from psychophysical and recent functional brain imaging studies is reviewed.

Long-Term Memory
Long-term memory can be categorized into two primary types: explicit and implicit memory. Explicit memory, also known as declarative memory, involves the conscious recollection of information that we deliberately try to remember, recall, and articulate. This type of memory encompasses specific facts, events, and...
