Chapter 11 Working memory

Abstract: Publisher Summary This chapter focuses on the modern notion of short-term memory, called working memory. Working memory refers to the temporary maintenance of information that was just experienced or just retrieved from long-term memory but no longer exists in the external environment. These internal representations are short-lived, but can be maintained for longer periods of time through active rehearsal strategies, and can be subjected to various operations that manipulate the information in such a way that makes it useful for goal-directed behavior. Working memory is a system that is critically important in cognition and seems necessary in the course of performing many other cognitive functions, such as reasoning, language comprehension, planning, and spatial processing. This chapter demonstrates the functional importance of dopamine to working memory function in several ways. Elucidation of the cognitive and neural mechanisms underlying human working memory is an important focus of cognitive neuroscience and neurology for much of the past decade. One conclusion that arises from research is that working memory, a faculty that enables temporary storage and manipulation of information in the service of behavioral goals, can be viewed as neither a unitary, nor a dedicated system. Data from numerous neuropsychological and neurophysiological studies in animals and humans demonstrates that a network of brain regions, including the prefrontal cortex, is critical for the active maintenance of internal representations.

Cognitive Architecture and Instructional Design

Abstract: Cognitive load theory has been designed to provide guidelines intended to assist in the presentation of information in a manner that encourages learner activities that optimize intellectual performance. The theory assumes a limited capacity working memory that includes partially independent subcomponents to deal with auditory/verbal material and visual/2- or 3-dimensional information as well as an effectively unlimited long-term memory, holding schemas that vary in their degree of automation. These structures and functions of human cognitive architecture have been used to design a variety of novel instructional procedures based on the assumption that working memory load should be reduced and schema construction encouraged. This paper reviews the theory and the instructional designs generated by it.

Understanding the Representational Mind

Abstract: A model of writing in cognitive development, Understanding the Representational Mind synthesizes the burgeoning literature on the child's theory of mind to provide an integrated account of children's understanding of representational and mental processes, which is crucial in their acquisition of our commonsense psychology. Perrier describes experimental work on children's acquisition of a theory of mind and representation, offers a theoretical account of this acquisition, and gives examples of how the increased sophistication in children's theory of mind improves their understanding of social interaction and how, in the case of autistic children, an impairment results in social ineptitude. He analyzes the concepts of representation and metarepresentation as they appear in current discussion in the philosophy of cognitive science and explains how the unfolding of mental representation enables infants to comprehend change over time, engage in pretence, and use representational systems like pictures and language. Perrier goes on to show that around age four children become able to understand the representational nature of pictures and language and to distinguish appearance from reality. Introducing basic distinctions in philosophy of mind for characterizing the mental, Perrier discusses differences in how commonsense and cognitive psychology view the mind. Tracing the onset of a commonsense psychology in the social and emotional awareness of early infancy, he reveals how the child begins to take a cognitive, representational view of the mind with repercussions for children's episodic memory, self control, and their ability to engage in deception. Perrier concludes by describing the observed developmental changes as a case of theory change And contrasts his thesis with competing proposals.

Managerial and Organizational Cognition: Notes from a Trip Down Memory Lane

Abstract: The study of cognition in organizations has burgeoned in recent years. Top-down information processing theory suggests that individuals create knowledge structures to help them process information and make decisions. While the benefits of employing such knowledge structures are widely noted, there is a growing concern that they can limit decision makers' abilities to understand their information environments and thus, compromise their decision making. This issue has captured the imagination of managerial and organizational cognition researchers. To date, their inquiry has been eclectic in focus and method. To order and advance this work, the author reviews extant research on the developmental origins and decision consequences of both the content and structure of knowledge structures at multiple levels of analysis. A host of research challenges are identified to help develop a better understanding of knowledge structure representation, development, and use in organizations.
