Recognition by familiarity is preserved in Parkinson's without dementia and Lewy-Body disease.
2010
Objective The retrieval deficit hypothesis states that the lack of deficit in recognition often observed in patients with Parkinson's disease is because of the low retrieval requirements of the task, given that these patients have retrieval and not encoding deficits. To test this hypothesis we investigated recognition memory by familiarity in Parkinson's patients and in patients with Lewy Bodies disease and Parkinson with dementia. Method We analyzed to what extent the experimental groups were able to recognize by familiarity in a typical yes/no recognition memory task. The experimental groups were patients with early nondemented Parkinson's disease, advanced nondemented Parkinson's disease…
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…
Associative and implicit memory performance as a function of cognitive reserve in elderly adults with and without mild cognitive impairment
2016
AbstractThis study aims to analyze implicit and explicit memory performance as a function of cognitive reserve (CR) in a healthy control group (N = 39) and a mild cognitive impairment (MCI) group (N = 37). Both groups were subdivided into high and low cognitive reserve, and were asked to complete an explicit and implicit associative recognition tasks. The results showed that the control group was able to learn both tasks (η2 = .19, p < .0001), and the high CR group fared better (η2 = .06, p < .05). The MCI sample, conversely, was unable to learn the implicit relationship, and showed very little learning on the explicit association task. Participants diagnosed with MCI showed little pl…
La memòria recuperada: l’ús dels relats biogràfics en la segona i tercera generació dels emigrants valencians als Estats Units d’Amèrica a principi d…
2021
És habitual quan es fa ús del mètode biogràfic recollir els relats directament d'aquells que van viure els fets narrats, siguin estos tota una vida o alguns aspectes que l'investigador desitgi que siguin destacats. En la investigació duta a terme sobre la recuperació de la memòria dels emigrants valencians als Estats Units d'Amèrica durant les dues primeres dècades del segle XX això es presenta com un fet impossible: els que van viure en primera persona l'emigració ja han desaparegut. Es podria pensar que amb ells desapareixien també les seues històries. Però gràcies a un exhaustiu treball amb els seus descendents (filles i fills, nétes i néts, nebodes i nebots) i fent ús de tècniques que s…

Olvido dirigido de falsas memorias: ¿Podemos olvidar intencionalmente una falsa memoria?
2003
Directed forgetting of false memories: Can we forget a false memory? In two directed forgetting experiments subjects were required to forget some false memories. In experiment 1 the 13 words from list 1 were related to a non presented critical word whereas the 13 words from list 2 were unrelated. In experiment 2 both list 1 and 2 had 18 words: 6 words related to a first critical word, 6 related to a second critical word, and the last 6 words to a third critical word. None of both experiments found inhibition of such false memories suggesting that is not possible to forget a false memory. Even in experiment 2 there was a trend to the appearance of a postsuppression rebound that would indicat…
An overall decline both in recollection and familiarity in healthy aging
2015
Background: In the area of recognition memory, the experimental data have been inconsistent about whether or not familiarity declines in healthy aging. A recent meta-analysis concluded that familiarity is impaired when estimated with the remember-know procedure, but not with the process- dissociation procedure. Method: We present an associative recognition experiment with remember-know judgments that allow us to estimate both recollection and familiarity using both procedures in the same task and with the same participants (a sample of healthy older people and another sample of young people). Moreover, we performed a within-subjects manipulation of the type of materials (pairs of words or p…
Are cognitive interventions effective in alzheimer´s disease? a controlled meta-analysis of the effects of bias
2016
Objective: There is limited evidence about the efficacy of cognitive interventions for Alzheimer's disease (AD). However, aside from the methodological quality of the studies analyzed, the methodology used in previous meta-analyses is itself a risk of bias as different types of effect sizes (ESs) were calculated and combined. This study aimed at examining the results of nonpharmacological interventions for AD with an adequate control of statistical methods and to demonstrate a different approach to meta-analysis. Method: ESs were calculated with the independent groups pre/post design. Average ESs for separate outcomes were calculated and moderator analyses were performed so as to offer an o…

Testimony, updating and storytelling: the historical memory of Spanish Civil War in contemporary Catalan literature
2019
El tema de la Guerra Civil i la dictadura franquista ha generat a l’Estat espanyol des de mitjans dels noranta ençà una quantitat ingent de novel·les, articles periodístics, investigació històrica i producció audiovisual que palesa la vigència problemàtica del tema. Aquest article vol centrar-se en un aspecte d’aquesta producció: la referida a les narracions que dintre de la literatura catalana actual l’han abordat. Es tracta d’un corpus d’obres extens en el qual han participat alguns dels escriptors més destacats. La nostra aproximació pretén estudiar aquesta vasta i diversa producció, mirant d’esbrinar les motivacions i els plantejaments narratius que regeixen aquestes propostes. Hi hem d…
