The Relationship

Previous studies are inconsistent in their findings about the relationship between external involvement and performance. The authors attribute this inconsistency to the misfit between external involvement and business environment. Drawing the concept of fit between information processing capabilities and needs from information processing theory, they develop the fitting patterns between external involvement and business environment and examine their impacts on performance. Information processing capabilities are measured by the degree of two types of external involvement in the NPD process and information processing needs are assessed based on three dimensions of business environment. Cluster analysis was used to develop the taxonomies of fit between external involvement and business environment. Analysis of variance (ANOVA) was used to examine the impacts of fitting patterns between external involvement and business environment on performance. The results reveal six fitting patterns between external involvement and business environment. ANOVA results show that the fitting patterns between external involvement and business environment are related to both operational performance and business performance, supporting our fit theory.

Modern flight and weapon platforms are becoming more and more sophisticated. New sensors and weapon systems are added, giving the operator more information to process before acting or deciding. Today, many pilots feel they reach their information processing limits during difficult missions and during difficult circumstances. The purpose of the present study has been to measure mental workload, situational awareness and performance during specific air-to-ground missions in both simulated and real flight in order to assess operator status. Specifically to compare simulated versus real flight regarding the concepts, to analyze the relationships between physiological reactions, situational awareness, and experienced mental workload and also develop and test causal models of operator function. A second purpose of the study was to develop practically useful methods for analyzing mental workload and performance during operative conditions.

And Performance

With the development of information processing technology, 2-D DCT has been used more and more widely. But the 2-D DCT is accomplished by computing twice 1-D DCT successively, and cannot embody the total space characteristic of 2-D transform well. To overcome such drawbacks, the paper has broken the traditional thinking of DCT operation, and proposed 2-D SDCT operation method. First, some new 2-D matrix operation principles are defined. Then, the transform basic matrix used for 2-D SDCT operation was build and the operation principle of 2-D SDCT is described in detail. Finally, the performance of 2-D SDCT was described systematically. The theoretical analysis shows that the proposed method makes 2-D DCT succinct to express, easy to comprehend and convenient to operate.

Experimental Findings

This article presents an information-processing approach to the assessment of learning disabled students' intellectual performance. The model is based on the assumption that intelligent behavior is comprised of a variety of problem-solving strategies. Its validity rests on experimental findings of Brown (1978), Neisser (1976, 1981), Newell and Simon (1972), and Sternberg (1977, 1978, 1979, 1981), to name a few. Each plane of assessment includes decisions about: (a) the relationship between hypothesis testing and overall performance; (b) the knowledge base which influences strategy development; (c) the ability to coordinate, direct, and organize search strategies; (d) the metacognitive parameters of learning and performance; and (e) the abstracting of problem-solving strategies. Sample “probing” questions are provided to direct assessment procedures. Within each plane, different components are assessed. The article presents an account of child problem solving and illustrates its underlying assumptions with a “thinking aloud” protocol. The model suggests that substrategy behavior may develop independently or within different planes. Finally, conclusions are drawn to direct intervention approaches.

Learning And Performance

Adey and his associates have asserted that theta electrical activity recorded from the hippocampus during learning and performance reflects the role of this structure in information processing, decision making and memory consolidation. This notion was recently questioned by Douglas (1967) who concluded that the tasks employed by Adey and his associates to assess theta activity were tasks which the lesion literature indicated do not requite hippocampal functioning to be learned. The present paper questions Douglas' assertion by describing studies in the lesion literature which demonstrate that the tasks used by Adey and his co-workers may actually require hippocampal functioning to be learned.

And Performance

The effects of two training procedures on learning and performance are compared. Performers select a response alternative for each stimulus on Trial 1 and receive feedback in terms of “Right” or “Wrong”. Observers receive the same information by listening to the experimenter. Experiment I tests the hypothesis that performers and observers are using a different learning strategy when there are only two response alternatives available for each stimulus on Trial 1. A recognition procedure was used on Trial 2; each stimulus was followed by four alternatives, two of them being the same as presented on Trial 1. Subjects have to recognize the two “old” alternatives. Performers are always better at recognizing the chosen alternative, whereas observers are better at recognizing the correct alternative. Experiment II extends the comparison between performers and observers to a task with four response alternatives on Trial 1. There are no longer differences in performance between the two training procedures.
