Professional competences to promote healthy ageing across the lifespan: a scoping review

European Journal of Ageing

Social and healthcare professionals are key agents in this process; therefore, their training needs to be in agreement with societal needs. We performed a scoping review on professional competences for social and health workers to adequately promote healthy ageing throughout life, using the framework described by Arksey and O’Malley and the Joanna Briggs Institute Guidelines. A stakeholder consultation was held in each of the participating countries, in which 79 experts took part. Results show that current literature has been excessively focused on the older age and that more attention on how to work with younger population groups is needed. Likewise, not all disciplines have equally reflected on their role before this challenge and interprofessional approaches, despite showing promise, have not been sufficiently described. Based on our r...

Accuracy and speed of emotion recognition with face masks

Nevertheless, social interaction is limited via masks, and this impacts the accuracy and speed of emotional perception. In the present study, we assess the impact of mask-wearing on the accuracy and speed of emotion recognition. Fifty people (female n = 39, male n = 11) aged 19-28 participated in the study (M = 21.1 years). We used frontal photos of a Kosova woman who belonged to the same participants' age group, with a grey background. Twelve different pictures were used that showed the emotional states of fear, joy, sadness, anger, neutrality, and disgust, in masked and unmasked conditions. The experiment was conducted in a controlled laboratory setting. Participants were faster for identifying emotions like joy (1.507 ms) and neutral (1.971 ms). The participants were more accurate (emotions identification) in unmasked faces (M = 85.7%) than in masked faces (M = 73.8%), F(1,98) = 20.73, MSE = 1027.66, p ≤ .001, partial η² = 0.17. Masks make confusion and reduce the accuracy and speediness of emotional detection. This may have a notable impact on social interactions among peoples.

The Impact of Information About COVID-19 on the Endocrine Stress System and Cognitive Distortions

It is highly conceivable that elevation of the stress hormones, i.e., glucocorticoids and catecholamines, due to the infection, as well as the presence of psychosocial stressors, such as COVID-19 information, play a critical role in the development of these disorders. In the present study, the potential impact of exposure to COVID-19 information on the cognitive distortion and stress levels was analyzed in a population of 32 first-year medical sciences students using the stress assessment questionnaire (SAQ) and the posttraumatic cognitions inventory (PTCI) surveys. Both surveys demonstrated no acute change in the stress and post-traumatic cognition levels between medical sciences students who were either exposed or not to information ab...

Evolution de la capacité à sélectionner la meilleure stratégie au cours du vieillissement normal et pathologique : Effet de la répétition stratégique

Pour atteindre ces objectifs, nous avons conduit trois etudes, pour lesquelles nous avons adopte une approche experimentale ou nous avons utilise des strategies arithmetiques (i.e., methodes utilisees par un individu pour resoudre une tâche cognitive donnee). Nous avons recueilli nos donnees aupres d'individus jeunes, âges sains et patients atteints de la maladie d'Alzheimer (i.e., MA). Les principaux resultats montraient que (a) les adultes âges repetaient significativement plus que les adultes jeunes, et ce d'autant plus lorsque la strategie etait fortement active en memoire de travail ; cependant, (b) ils reussissaient a changer de strategie de maniere comparable aux adultes jeunes lorsque les latences entre leurs reponses et les stimuli suivant augmentaient ; et (c) les patients atteints de la MA avaient plus de difficultes a selectionner la meilleure strategie que les adultes âges, et ce d'autant plus lorsque le probleme etait difficile. Ce travail a donc permis de preciser les processus cognitifs impliques lors de la selection strategique et de comprendre les effets du vieillissement normal et pathologique sur ceux-ci. Nous discutons egalement de l'implication possible de ces resultats quant aux modeles theoriques de la selection strategique.

Strategy repetition in young and older adults: A study in arithmetic

Young and older adults had to provide the best estimates of multiplication problems like 47 ϫ 86. They had to select the best of 2 rounding strategies on each problem, the rounding-down strategy (i.e., doing 40 ϫ 80 ϭ 3,200) or the rounding-up strategy (i.e., doing 50 ϫ 90 ϭ 4,500). Data showed that both young and older adults repeated the same strategy over consecutive problems more often than chance and repeated strategies more often in the 2-prime condition (i.e., after executing one strategy to solve the 2 immediately preceding problems) than in the 1-prime condition (i.e., after executing a strategy on one immediately preceding problem). Moreover, this strategy repetition phenomenon increased with age, especially in the most difficult condition (e.g., when participants solved rounding-up problems in the 2-prime condition). Our findings have important theoretical and empirical implications for computational models of strategy selection and for furthering our understanding of strategic development during adulthood.

Strategy selection in Alzheimer patients: A study in arithmetic

A total of 60 participants (30 healthy older adults, HOA; 30 AD patients) were asked to select the best rounding strategy to estimate products of multiplication problems (e.g., estimating 42 × 76 by rounding operands down or up, like doing 40 × 70 = 2800 or 50 × 80 = 3200). We identified strategies used on each problem and measured solution latencies and percentage errors with each strategy as a function of problem characteristics. Older adults and AD patients were able to use both available strategies. However, AD patients were less able to select the best strategy than HOA, especially on problems for which selecting the best strategy was most difficult. Moreover, AD patients significantly repeated the preceding strategies across successive problems more often than HOA. Our findings have important implications for further our understanding of dementia-related differences in strategic aspects of cognitive performance.
