Memory encoding in Alzheimer's disease: an fMRI study of explicit and implicit memory.
Alzheimer's disease is the most common cause of dementia in older adults. Although the cognitive deficits and pathologic hallmarks of Alzheimer's disease have been well characterized, few functional imaging studies have examined the functional competency of specific brain regions and their relationship to specific behavioural memory deficits in Alzheimer's disease. We used functional MRI (fMRI)...
متن کاملimplicit and explicit memory bais in depression and anxiety
williams, watts, macleod and mathews' (1988) model of anxiety and depression leads to the prediction that anxious patients will show mood – congreuent implicit memory bias, while depressed patients will show mood-congruent explicit memory bias.although this prediction has been supported by some researchers (denny & hunt, 1992 mathews, moog, et al , 1989 watkins, et al, 1992), the reliabili...
متن کاملImplicit and explicit memory models
In describing phenomena associated with memory, people typically rely on an implicit or intuitive theory that assumes the mind is like a space in which memories are stored, just as objects are stored in physical space. Utilization of information is often described as a search process through the space. The argument is briefly presented that almost all explicit memory theories embody the same as...
متن کاملMedial temporal lobe involvement in an implicit memory task: evidence of collaborating implicit and explicit memory systems from FMRI and Alzheimer's disease.
We used a prototype extraction task to assess implicit learning of a meaningful novel visual category. Cortical activation was monitored in young adults with functional magnetic resonance imaging. We observed occipital deactivation at test consistent with perceptually based implicit learning, and lateral temporal cortex deactivation reflecting implicit acquisition of the category's semantic nat...
متن کاملStudy of Numerical Processing Speed, Implicit and Explicit Memory, Active and Passive Memory, Conservation Abilities, and Visual-Spatial Skills of Students with Dyscalculia
Background and Purpose: Learning disorder is one of the common disorders in students, which can lead to the occurrence of educational problems and secondary disorders in them. Based on psychopathological criteria, dyscalculia is one of the subcategories of learning disorder. Children with this disorder have problems in perception of spatial relations and in different cognitive abilities. Theref...
