Three experiments were undertaken to examine the processing limitations that underlie multiple task performance and, ultimately, to test the theory that there exists a time-sharing ability which is general and can be assessed through the simultaneous presentation of any two or more sufficiently demanding tasks. Subjects were males and/or females…

Three experiments were conducted investigating information processing in a person perception task. A sequential judgement paradigm was employed in which subjects judged the suitability of stimulus persons for two different occupations. Traits describing each person were present for subjects' first judgements but not their second. Second decision…

Two experiments are reported examining the influence of the relationship between judgemental sets on the processing and integration of information in a person perception task. Experiment I showed that subjects made an occupational judgement about another more quickly when the judgement was similar rather than dissimilar to a previous occupational…

The document reports on an extension of task analysis methodology. The concept of strategic principles or task strategies implicit in the job activities of highly proficient performers is examined with the intent of improving training. The goal is to identify or invent such strategies, as appropriate, and then proceed with training encouraging use…

This paper presents a theory of human information processing. Information processing refers to the perception, encoding, recoding, storage, retrieval and manipulation of information by the brain. This theoretical model takes a developmental perspective in explaining human performance on tasks that require thinking, reasoning and remembering.…

Piaget, in describing the sequence of classificatory development, describes class inclusion as composed of two processes; hierarchical classification and post-whole comparisons. In the experiment reported here, elementary school children, trained in the concept of sets in first grade mathematics were given a task where they were required to assess…
