Computer Metaphor Theory Elements of cognitive theory have been challenged by some contemporary researchers. The computer metaphor theory of the cognitive system has been criticized because cognitive computer models (a) are weak in the performance of tasks involving pattern recognition, (b) poor at tasks that involve simultaneous satisfaction of socalled soft constraints, and (c) contrast poorly with the function of the brain (Lloyd, 1990, pp. 9091). The human brain excels at tasks involving pattern recognition. Even the best digital computer or artificial intelligence system, however, cannot perform even moderately well in the area of pattern recognition. All of these concepts are directly related to the application of presentation media, because each of these concepts bears on the ways in which different individuals absorb and comprehend information.Awareness of the environment cannot be isolated from the environment itself. Treating perception is a functional context causes the concept to be an achievement, as opposed to being a process. Awareness of the terms within which effective action must occura description of the environmentis perception. The contention is that experiences such as dreams, hallucinations, and imagination are derivative in character. Thus, such experiences cannot be completely explained until one's perception of the environment is understood. One's perception of one's environment determines to a great extent the way in which one processes information received. Thus, effective presentation media must be structured to complement such processes.
