Immersive Versus Non-immersive Experience: Exploring the Feasibility of Memory Assessment Through 360° Technology
2019
Episodic memory is essential to effectively perform a number of daily activities, as it enables individuals to consciously recall experiences within their spatial and temporal environments. Virtual Reality (VR) serves as an efficacious instrument to assess cognitive functions like attention and memory. Previous studies have adopted computer-simulated VR to assess memory, which realized greater benefits compared to traditional procedures (paper and pencil). One of the most recent trends of immersive VR experiences is the 360° technology. In order to evaluate its capabilities, this study aims to compare memory performance through two tasks: immersive task and non-immersive task. These tasks d…
Subjective states associated with retrieval failures in Parkinson's disease.
2013
Abstract Instances in which we cannot retrieve information immediately but know that the information might be retrieved later are subjective states that accompany retrieval failure. These are expressed in feeling-of-knowing (FOK) and Tip-of-the-tongue (TOT) experiences. In Experiment 1, participants with Parkinson’s disease (PD) and older adult controls were given general questions and asked to report when they experienced a TOT state and to give related information about the missing word. The PD group experienced similar levels of TOTs but provided less correct peripheral information related to the target when in a TOT state. In Experiment 2, participants were given a Semantic (general kno…
Acute psychosocial stress effects on memory performance: Relevance of age and sex.
2018
In recent decades, there has been a growing interest in investigating the effects of chronic and acute stress on cognitive processes, especially memory performance. However, research focusing on acute stress effects has reported contradictory findings, probably due to the many factors that can moderate this relationship. In addition to factors related to the individual, such as sex and age, other factors, such as the type of memory assessed, can play a critical role in the direction of these effects. This review summarizes the main findings of our research group and others about the effects of acute psychosocial stress on memory performance in young and older people of both sexes, taking in…
A low cortisol response to acute stress is related to worse basal memory performance in older people
2014
Age-related memory decline has been associated with a faulty regulation of the hypothalamus-pituitary-adrenal axis (HPA-axis). The aim of this study was to investigate whether the magnitude of the stress-induced cortisol increase is related to memory performance when memory is measured in non-stressful conditions. To do so, declarative and working memory performance were measured in 31 men and 35 women between 55 and 77 years of age. On a different day, the magnitude of their cortisol response to acute psychosocial stress was measured. The relationship between the cortisol response and memory performance was U shaped: a low cortisol response to stress was related to poorer declarative and w…
The relationship between cortisol and cognitive function in healthy older people: The moderating role of Apolipoprotein E polymorphism.
2018
The Apolipoprotein E4 (ApoE-epsilon 4) allele has been suggested as the main risk factor for late onset Alzheimer's disease (AD), whereas the ApoE-epsilon 2 allele has been proposed as a protective factor. These proposals have increased the interest in the effect of the ApoE genotype in healthy people. Additionally, high cortisol levels have been related to negative effects on cognition. However, few studies have investigated the relationship between cognitive performance and cortisol, taking into account the different ApoE alleles. For this reason, the aim of this study was to evaluate different cognitive domains (declarative and working memory, attention, and executive function) and their…
Does short-term odour memory increase with expertise? An experimental study with perfumers, flavourists, trained panellists and novices
2011
We have examined short-term memory performance for odour recognition as a function of expertise. Experts (perfumers and flavourists), trained panellists, and novices studied three sets of common and uncommon (perfumery and flavour raw materials) odours with intentional encoding instructions. The three sets included three, six and 12 odours, respectively. As expected, recognition performance indicated an expertise effect: hit rates increased with expertise, whereas false alarm rates decreased. This effect, however, is mediated by the type and number of odours. For common odours, the effect of expertise is significant only for the larger odour set. For uncommon odours, the effect of expertise…
Gaze cueing in naturalistic scenes under top-down modulation – Effects on gaze behaviour and memory performance
2022
Humans as social beings rely on information provided by conspecifics. One important signal in social communication is eye gaze. The current study (n = 93) sought to replicate and extend previous findings of attentional guidance by eye gaze in complex everyday scenes. In line with previous studies, longer, more and earlier fixations for objects cued by gaze compared to objects that were not cued were observed in free viewing conditions. To investigate how robust this prioritization is against top-down modulation, half of the participants received a memory task that required scanning the whole scene instead of exclusively focusing on cued objects. Interestingly, similar gaze cueing effects oc…
The cortisol awakening response and memory performance in older men and women.
2012
Summary 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 declarative memory (a paragraph recall test and a word list learning test) and two tests measuring working memory (a spatial span test and a spatial working memory test). Among those participants who showed the CAR on two consecutive days, we found that a greater CAR was related to poorer declarativ…
Expertise and memory for beers and beer olfactory compounds
2007
Abstract Do beer experts have better recognition memory for beers than novices? And can recognition memory for beers be predicted on the basis of recognition memory for beer odor compounds? We compared the memory performance of “beer experts” and novices in two recognition tasks. The first task was performed ortho- and retronasally with beers, and the second orthonasally with beer odor compounds. As a control we also compared the performance of “experts” and novices on an identification task and a same/different discrimination task. “Beer experts” outperformed novices in both the identification task and the recognition memory task with both beers and odor compounds, but only for beers they …
