First, the span of absolute judgment and the span of immediate memory impose severe limitations on the amount of information that we are able to receive, process, and remember. By organizing the stimulus input simultaneously into several dimensions and successively into a sequence or chunks, we manage to break (or at least stretch) this informational bottleneck. Second, the process of recoding is a very important one in human psychology and deserves much more explicit attention than it has…

A wide variety of data on capacity limits suggesting that the smaller capacity limit in short-term memory tasks is real is brought together and a capacity limit for the focus of attention is proposed.

Chunking: An Interpretation Bottleneck

An important representational constraint that arises from the restricted ca­ pacity of distributed representations for encoding composed, structured objects is shown to be related to some key properties of human short-term memory.

Simultaneous better than sequential for brief presentations.

This paper reports on experiments designed to overcome limitations in the information transfer between the large number of alphanumeric characters available and the acquiring of these characters, and used shorter SOA's than did previous investigators.

How Big Is a Chunk?

It is shown that, by viewing experimentation in a parameter-estimating paradigm instead of a hypothesis-testing paradigm, one can obtain much more information from experiments—information that, combined with contemporary theoretical models of the cognitive processes, has implications for human performance on tasks quite different from those of the original experiments.

SPAN OF SHORT-TERM MEMORY FOR VISUALLY PRESENTED REDUNDANT STIMULI

The role of the short-term memory in human information processing hardly requires special mention.It is absolutely indispensable for decoding sequentially coded information as well as for

Pigeons and the Magical Number Seven

P pigeons seem to be severely limited in their ability to identify such stimuli when they are members of a large set, the result of an imperfect memory coupled with a decision process that uses only a small sample of the information in this memory.

The informational transmission with elementary auditory displays of a large number of finely subdivided stimulus dimensions was investigated and nearly perfect identification was obtained with skilled listeners when each dimension was crudely subdivided into two alternative states.

Whereas the ear's sensitivity for detecting a difference in frequency between two tones is remarkably acute, the ability of listeners to identify (and name) tones presented in isolation is relatively

Determined discrimination accuracy using the method of absolute judgment for a series of stimuli varying along the single dimensions of size, hue and brightness was considerably greater than that obtained for any of the compounding dimensions used alone.
