UNLABELLED It has been proposed that the language problems in specific language impairment (SLI) arise from basal ganglia abnormalities that lead to impairments with procedural and working memory but not declarative memory. In SLI, this profile of memory functioning has been hypothesized to underlie grammatical impairment but leave lexical knowledge relatively unaffected. The current study exam...

What memory systems underlie grammar in children, and do these differ between typically developing (TD) children and children with specific language impairment (SLI)? Whilst there is substantial evidence linking certain memory deficits to the language problems in children with SLI, few studies have investigated multiple memory systems simultaneously, examining not only possible memory deficits ...

Increased levels of circulating glucocorticoids (GCs) due to stress have been shown to result in enhanced consolidation and impaired retrieval of memory in humans. Several studies have shown that participants may be categorized as high and low responders with regard to GC levels elicited by stress. In the current study, we studied the differential effects of acute psychosocial stress on declara...

Mounting behavioral evidence in humans supports the claim that sleep leads to improvements in recently acquired, nondeclarative memories. Examples include motor-sequence learning; visual-discrimination learning; and perceptual learning of a synthetic language. In contrast, there are limited human data supporting a benefit of sleep for declarative (hippocampus-mediated) memory in humans (for rev...

Participation of two medial temporal lobe structures, the hippocampal region and the amygdala, in long-term declarative memory encoding was examined by using positron emission tomography of regional cerebral glucose. Positron emission tomography scanning was performed in eight healthy subjects listening passively to a repeated sequence of unrelated words. Memory for the words was assessed 24 hr...

The prevailing view of the medial temporal lobe (MTL) holds that its structures are dedicated to long-term declarative memory. Recent evidence challenges this position, suggesting that perirhinal cortex (PRc) in the MTL may also play a role in perceptual discriminations of stimuli with substantial visual feature overlap. Relevant neuropsychological findings in humans have been inconclusive, lik...

Three important developments have occurred in the area of memory during the past decade. The first was the recognition that there is more than one kind of memory (Cohen 1984; Schacter 1987; Squire 1982; Tulving 1985). Declarative memory (or, explicit memory) affords the capacity for conscious recollections about facts and events. This is the kind of memory that is usually referred to when the t...

We investigated structural brain damage in subjects who had suffered severe and diffuse traumatic brain injury (TBI), and examined its relationship with declarative memory impairment. Cortical thickness, diffusion tensor imaging (DTI), and volumetric and shape data of the hippocampus were assessed in a group of 26 adults with severe TBI in the chronic stage and 22 healthy matched controls. Decl...

I develop a conceptual model of the micro-foundations of routines that incorporates autobiographical memories, defined as the memories people have of their own lives. I argue that individuals ́ autobiographical memories are transformed into collective declarative memory via transactive memory processes, and that the resulting memory systems play a significant role in the development, adaptation ...

The activity and regulation of the hypothalamus-pituitary-adrenal axis has been related to cognitive decline during aging. This study investigated whether the cortisol awakening response (CAR) is related to memory performance among older adults. The sample was composed of 88 participants (44 men and 44 women) from 55 to 77 years old. The memory assessment consisted of two tests measuring declar...
