Sleep benefits the consolidation of both declarative and nondeclarative memories, however the question if these two memory systems profit from sleep in more or less similar ways is still under debate. Studying the on-line and off-line consolidation of declarative and nondeclarative memory tasks in depressed patients and healthy controls, we here present a clear double dissociation between memor...

The proposition that declarative memory deficits are systematically related to smaller hippocampal volume was tested in a relatively large sample (n = 95) of U.S. military veterans with and without combat-related posttraumatic stress disorder. This correlative analysis was extended by including multiple measures of verbal and visual declarative memory and multiple memory-relevant regional brain...

The results reported in this paper were obtained through the study of 43 work-units belonging to five business firms in a large group of Tunisian companies. Using the declarative, procedural and judgmental dimensions of organizational memory, interaction effects were detected between IT and organizational memory. Analyses of the data support the view that storage technologies interact with decl...

Age-related changes in representational flexibility are a characteristic feature of declarative memory development. The authors suggest that a qualitative shift in the nature of infants’ memory representations accounts for increasing memory flexibility with age. We will argue that a comprehensive theory of declarative memory development must (1) account for the effect of experience on flexibili...

Everyday experience suggests that highly emotional events are often the most memorable, an observation supported by psychological and pharmacological studies in humans. Although studies in animals have shown that nondeclarative emotional memory (behaviors associated with emotional situations) may be impaired by lesions of the amygdala, little is known about the neural underpinnings of emotional...

The idea that memory is not a single mental faculty has a long and interesting history but became a topic of experimental and biologic inquiry only in the mid-20th century. It is now clear that there are different kinds of memory, which are supported by different brain systems. One major distinction can be drawn between working memory and long-term memory. Long-term memory can be separated into...

In Nadel’s comment on our study (Zola-Morgan et al., 1994), he reiterates the view that the hippocampus has a selective role in spatial memory, i.e., the hippocampus stores information about nonegocentric space (viewpoint-independent space; O’Keefe and Nadel, 1978; Nadel, 199 1). In the context of our report, he points out that four monkeys with lesions limited to the hippocampal region (the H ...

The results reported in this paper were obtained through the study of 43 work-units belonging to five business units in a large group of Tunisian companies. Using the declarative, procedural and judgmental dimensions of organizational memory, interaction effects were detected between dimensions of information technology and dimensions of organizational memory. Analyses of the data support the v...
