Document Summary
Attentional demand influences: habits and automatized tasks demand few resources, cognitive complexity (long division vs. multiplication, working memory demands of the task. Can"t just assume that presented information will be attended to and processed. Encourage development of automaticity and exploit it. Beware of requiring non-routine responses to automated behaviors. Utilize dissimilar modalities, processing codes, output responses, and stages of processing, if requiring time sharing. Multiple resource theory: tasks using different resources interfere less with each other: modalities: auditory, visual, tactile, visual processing channel: focal (reading), ambient (processing flow fields, stages of processing: perception, cognition, response, codes: spatial, verbal. Two tasks using different resources interfere less. Stages in processing: 2 controlling tasks worse than perceptual + control tasks.
