The picture superiority effect in associative memory: A developmental study.
2018
We tested whether semantic relatedness between to-be-remembered items and item presentation format (pictorial vs. verbal) affects associative recall. Fifty-nine children (11-13 years old) and forty young adults (age 18-30) completed a learning and recall task for semantically related (e.g., padlock-key) and unrelated (e.g., lemon-piano) picture-picture, word-picture, and word-word pairs. The data revealed memory advantage for semantically related item pairs, and for pictures compared to words. A picture superiority effect was found exclusively for pure picture pairs. Despite pronounced differences in memory accuracy, the effect of semantic relatedness and the picture superiority effect were…
Short-term memory predictions across the lifespan: monitoring span before and after conducting a task.
2016
Our objective was to explore metamemory in short-term memory across the lifespan. Five age groups participated in this study: 3 groups of children (4-13 years old), and younger and older adults. We used a three-phase task: prediction-span-postdiction. For prediction and postdiction phases, participants reported with a Yes/No response if they could recall in order a series of images. For the span task, they had to actually recall such series. From 4 years old, children have some ability to monitor their short-term memory and are able to adjust their prediction after experiencing the task. However, accuracy still improves significantly until adolescence. Although the older adults had a lower …
Do animacy effects persist in memory for context?
2017
International audience; The adaptive view of human memory (Nairne, 2010) assumes that animates (e.g., rabbit) are remembered better than inanimates (e.g., glass) because animates are ultimately more important for fitness than inanimates. Previous studies provided evidence for this view by showing that animates were recalled or recognized better than inanimates (e.g., Nairne, VanArsdall, Pandeirada, Cogdill, & LeBreton, 2013), but they did not assess memory for contextual details (e.g., where animates vs. inanimates occurred). In this study, we tested recollection of spatial information (Study 1) and temporal information (Study 2) associated with animate versus inanimate words. The findings …
Can Word Puzzles be Tailored to Improve Different Dimensions of Verbal Fluency? A Report of an Intervention Study
2016
Verbal fluency is commonly used as a proxy measure of executive functioning, as it involves cognitive flexibility, working memory, and inhibitory control. Previous research has demonstrated that crosswords can be a useful means of improving verbal fluency, results consistent with the cognitive reserve hypothesis; the form of verbal fluency affected has, however, differed across studies. The present study sought to assess the extent to which it was possible to target phonemic (PVF) and semantic verbal fluency (SVF) separately through word puzzles designed to focus on semantic/thematic and structural clues respectively. Fifty-three university students were randomly assigned to one of three gr…
Left insular cortex and left SFG underlie prismatic adaptation effects on time perception: Evidence from fMRI
2014
Prismatic adaptation (PA) has been shown to affect left-to-right spatial representations of temporal durations. A leftward aftereffect usually distorts time representation toward an underestimation, while rightward aftereffect usually results in an overestimation of temporal durations. Here, we used functional magnetic resonance imaging (fMRI) to study the neural mechanisms that underlie PA effects on time perception. Additionally, we investigated whether the effect of PA on time is transient or stable and, in the case of stability, which cortical areas are responsible of its maintenance. Functional brain images were acquired while participants (n = 17) performed a time reproduction task an…
Motivated forgetting reduces veridical memories but slightly increases false memories in both young and healthy older people.
2017
The aim of the current study is to examine the effects of motivated forgetting and aging on true and false memory. Sixty young and 54 healthy older adults were instructed to study two lists of 18 words each. Each list was composed of three sets of six words associated with three non-presented critical words. After studying list 1, half of the participants received the instruction to forget List 1, whereas the other half received the instruction to remember List 1. Next, all the subjects studied list 2; finally, they were asked to remember the words studied in both lists. The results showed that when participants intended to forget the studied List 1, they were less likely to recall the stud…
Comparison between Spanish young and elderly people evaluated using Rivermead Behavioural Memory Test
2010
The first objective of this work was to compare scores obtained in the daily memory function between young and elderly people, and to check whether there are differences between the groups for each of the profile scores obtained in the memory test. A second aim of this paper is to study the relationship between everyday memory and age, while controlling for gender and educational level. The total and profile scores obtained in the Rivermead Behavioural Memory Test were compared in a sample of 60 young and 120 elderly people from Valencia (Spain). Results showed significant differences between the two groups: those between 18 and 30 years obtained a higher average than those over 65. Once th…
The effects of instrumental reminiscence on resilience and coping in elderly
2014
A B S T R A C T Objectives: Aging, as a stage of development is marked by major changes to which the subject must adapt. Instrumental reminiscence is based on recalling times one coped with stressful circumstances, and analyzing what it took to adapt in those situations. The purpose of the present study was to analyze the effectiveness of an instrumental reminiscent program to enhance adaptive capacity (problemfocused coping and emotion-focused) and resilience in older adults. Method: Thirty participants noninstitutionalized conducted a pre and post assessment on a treatment consisting of the Mini-Mental State Examination (MMSE), Brief Resilient Coping Scale and Stress Coping Questionnaire …
Structural priming is supported by different components of nondeclarative memory: Evidence from priming across the lifespan
2017
Abstract Structural priming is the tendency to repeat syntactic structure across sentences and can be divided into short-term (prime to immediately following target) and long-term (across an experimental session) components. Current theories of structural priming propose that different memory systems support these components, however, this study investigates how non-declarative memory could support both the transient, short-term and the persistent, long-term structural priming effects commonly seen in the literature. We propose that these characteristics are supported by different subcomponents of non-declarative memory: Perceptual and conceptual non-declarative memory respectively. Previou…
Longitudinal changes in odor identification performance and neuropsychological measures in aging individuals.
2015
To examine changes in odor identification performance and cognitive measures in healthy aging individuals. While cross-sectional studies reveal associations between odor identification and measures of episodic memory, processing speed, and executive function, longitudinal studies so far have been ambiguous with regard to demonstrating that odor identification may be predictive of decline in cognitive function.One hundred and 7 healthy aging individuals (average age 60.2 years, 71% women) were assessed with an odor identification test and nonolfactory cognitive measures of verbal episodic memory, mental processing speed, executive function, and language 3 times, covering a period of 6.5 year…
