Recognition memory deficits in mild cognitive impairment
2012
There is no agreement on the pattern of recognition memory deficits characteristic of patients diagnosed with mild cognitive impairment (Mel). Whereas lower performance in recollection is the hallmark of Mel, there is a strong controversy about possible deficits in familiarity estimates when using recognition memory tasks. The aim of this research is to shed Iight on the pattern of responding in recollection and familiarity in MCl. Five groups of participants were tested. The main participant samples were those formed by two Mel groups differing in age and an Alzheimer's disease group (AD), which were compared with two control groups, Whereas one of the control groups served to assess the p…
Differences in familiarity according to the cognitive reserve of healthy elderly people / Diferencias en familiaridad en función de la reserva cognit…
2014
AbstractThis study examines the relationship between cognitive reserve and familiarity processes in recognition memory. We hypothesize that people with high cognitive reserve are able to better compensate in alternative information retrieval processes. Forty-five participants, divided into high and low cognitive reserve groups, conducted a recognition experiment where they were asked to discriminate between studied and non-studied words that varied in perceptual familiarity. The results indicated that participants were able to use perceptual familiarity to improve their level of recognition. More importantly, people with high cognitive reserve used familiarity better than those with low cog…
Can there be learning potential in Parkinson’s disease? A comparison with healthy older adults
2017
Patients with Parkinson's disease may show certain cognitive impairments, although it is unclear how these deficits can affect their learning potential. The study aims to use the testing-the-limits technique to compare the potential for cognitive plasticity in a group of Patients with Parkinson's disease (N = 33) and a group of healthy older adults (N = 33). Sixty-six participants performed verbal learning test to analyze the learning potential. Repeated-measures analysis of variance showed significant main effects of time, group, and the interaction. There is a lower learning potential in subjects with Parkinson's disease; however, those still maintain a certain capacity for learning and, …
