Document Summary
Assign 4 tones a=1, b=2, d=4. hear tones and have to stat which one is which. If increase number of tones span of absolute judgment would be greater. Span of absolute judgment--how many items you can accurately discriminate. Cognitive scientists are more concerned with how info is transmitted. Major concern is how info-processing physically implemented in particular mental architecture. Idea that information-processing is sensitive to the format in which information is coded. Idea that information processing is a computational process. Transforming representations (inputs and outputs) in certain ways. Miller"s work suggests that the senses are information processing channels with limited capacity. Had nothing to say about the details of how those information-processing channels actually work ne is inate ntal n is els channels actually work. Next step towards cognitive science came with the development of particular info processing models of sensory systems and cognitive abilities.
