There is considerable contemporary interest in memory, both within the academy and in the public sphere. Little has been written by moral philosophers on the subject, however. In this timely book, Jeffrey Blustein explores the moral aspects and implications of memory, both personal and collective. He provides a systematic and philosophically rigorous account of a morality of memory, focusing on the value of memory, its relationship to identity, and the responsibilities associated with memory.

The early development of autobiographical memory is a useful case study both for examining general relations between language and memory, and for investigating the promise and the difficulty of interdisciplinary research in the cognitive sciences of memory. An otherwise promising social-interactionist view of autobiographical memory development relies in part on an overly linguistic conception of mental representation. This paper applies an alternative, ‘supra-communicative’ view of the relation between language and thought, along the lines developed by Andy Clark, to this developmental framework. A pluralist approach to current theories of autobiographical memory development is sketched: shared early narratives about the past function in part to stabilize and structure the child’s own autobiographical memory system.

We focus on the functional specificity of theta and alpha oscillations and show that theta is related to working memory, whereas alpha is related to semantic long-term memory. Recent studies, however, indicate that alpha oscillations also play an important role during short-term memory retention and retrieval. This latter finding provides support for the basic hypothesis suggested by Ruchkin et al.

Memory researchers have discussed the relationship between consciousness and memory frequently in the last few decades. Beginning with research by Warrington and Weiskrantz (1968; 1970), memory has been shown to influence task performance even without awareness of retrieval. Data from amnesic patients show that a study episode influences task performance despite their lack of conscious memory for the study session. More recently, issues of intentionality, awareness, and the relationship between conscious and unconscious forms of memory have come to the forefront. Conscious memory has sometimes been defined by intention to retrieve and sometimes by awareness of retrieval. This distinction has been debated as measurement methodologies have developed. In addition, the functional relationship between conscious and automatic forms of memory has implications for measurement of memory processes and the development of models of memory task performance. Several measurement techniques for conscious and automatic memory are reviewed. The current state of these issues is also discussed.

Can memory be cast as a system that meshes events to actions? This commentary considers the concepts of mesh versus association, arguing that thus far the distinction is inadequate. However, the goal of shifting to an action-based view of memory has merit, most notably in emphasizing memory as a skill and in focusing on processes as opposed to structures.

“You have to begin to lose your memory, if only in bits and pieces, to realize that memory is what makes our lives. Life without memory is no life at all, . . . Our memory is our coherence, our reason, our feeling, even our action. Without it, we are nothing.” – Luis Buñuel..

The functional theory of memory set out in Glenberg's target article accords with recent proposals in the developmental literature with respect to event memory, conceptualization, and language acquisition from an embodied, experiential view. The theory, however, needs to be supplemented with a recognition of the sociocultural contribution to these cognitive processes and emerging structures.

Prospective memory is required for many aspects of everyday cognition, its breakdown may be as debilitating as impairments in retrospective memory, and yet, the former has received relatively little attention by memory researchers. This article outlines a strategy for changing the fortunes of prospective memory, for guiding new research to shore up the claim that prospective memory is a distinct aspect of cognition, and to obtain evidence for clear performance dissociations between prospective memory and other memory functions. We begin by identifying the unique requirements of prospective memory tasks and by dividing memory's prospective functions into subdomains that are analogous to divisions in retrospective memory (e.g., short- versus long-term memory). We focus on one prospective function, called prospective memory proper; we define this function in the spirit of James (1890) as requiring that we are aware of a plan, of which meanwhile we have not been thinking, with the additional consciousness that we made the plan earlier. We give an operational definition of prospective memory proper and specify how it differs from explicit and implicit retrospective memory and how it might be empirically assessed.

The problem of neural memory storage is discussed, based on the results of studies of memory impairment after hippocampal lesions, motor learning, and electrophysiological research on “spinal memory.” I support Shors & Matzel's major statements. The absence of reliable evidence on the LTP memory storage function and other data cast doubt on the synaptic theory of memory.
