Thinking and memory are inextricably linked. However, a "divide and rule" approach has led cognitive psychologists to study these two areas in relative isolation. With contributions from some of the leading international researchers on working memory and thinking, the present volume aims to break down the scientific divisions and foster scientific integration in the connections between these two core functions of cognition. Broadly defined, thinking comprises mentally driven change in current representations. The processes involved in such change include application of logical rules, heuristics, problem solving strategies, decision making, planning and comprehension of complex material. Memory involves the encoding, retention and retrieval of information, and the retention may be temporary or in a long-term knowledge base.; Thinking cannot occur in a vacuum; it relies on the long-term memory base and a temporary mental workspace. Despite the apparent limitations on mental workspace, humans can drive a car and hold a conversation, or store partial solutions while tackling other aspects of a problem. So too, some aspects of thinking are relatively resilient in the face of quite extensive brain damage, yet other aspects are remarkably vulnerable to neuroanatomical insults. Humans can solve complex problems with many alternative choice points and yet seem to be able to consider only a few hypotheses at any one time. These apparent paradoxes present significant scientific challenges as to how humans can be such successful thinkers despite their very limited working memory. The chapters herein represent a diversity of views as regards the nature or working memory and forms of human thinking. The links between working memory and thinking are directly addressed and made explicit, and in so doing this volume offers an increasingly integrated understanding of human thinking and memory.
