%A W J. Clancey %J Constraining Cognitive Theories: Issues and Options %T Interactive coordination processes: How the brain accomplishes what we take for granted in computer languages %X An example of sending two messages in an e-mail program reveals a fundamental sequence-construction mechanism by which perceptual categories and motor schema are automatically generalized. By this mechanism, the human brain accomplishes more flexibly what we take for granted in stored-program computers-ordered steps (a sequence of operators in a problem space), variable bindings, conditional statements, and subgoaling. %K neuroscience, interface design, transaction, situated action, situated cognition, perceptual-motor co-ordination, conceptualization, motor schema, memory, human learning, task analysis, cognitive modeling %P 165-190 %E Z.
