The 13 chapters in this book are based on papers presented at the 1974 Indiana Cognitive/Mathematical Psychology Conference, at which contributors were asked to emphasize the relatively broad theoretical significance of their work, to incorporate the work of others, and to speculate about future developments. Topics covered include the nature and function of phonetic categories; selective adaptation to speech; a normative model for redundancy gains in speech; dichotic listening and processing phonetic features; expectancy and judgment; the mind, the model, and the task in studying judgment; Bayes's theorem and theory of judgment and inference; the ordered output of a central processor in short-term storage; a process view of short-term retention; the basis for a memory system in short-term store; integration and inference in children's comprehension and memory; bringing order to cognitive structures; and answering questions from cognitive structures.
