Does a brief mindfulness intervention counteract the detrimental effects of ego-depletion in basketball free throw under pressure?

Research has shown that a brief mindfulness intervention may counteract the depleting effects of an emotion suppression task upon a subsequent psychological task that requires self-control. However, the effects of a brief mindfulness intervention on perceptual–motor tasks particularly in stressful situations have not yet been examined. The purpose of this study was to investigate whether a brief mindfulness intervention can counteract the detrimental effects of ego-depletion in basketball free throw performance under pressure. Seventy-two basketball players (mean age = 28.6 ± 4.0 yrs) were randomly assigned to one of the following 4 groups: depletion/mindfulness, no depletion/mindfulness, depletion/no mindfulness and control (no depletion/no mindfulness). The mindfulness intervention consisted of a 15-min breathe and body mindfulness audio exercise, while the control condition (no mindfulness) listened to an audio book. A modified Stroop color-word task was used to manipulate self–control and induce ego depletion. Participants performed 30 free throws before and after the experimental manipulations. Results showed that basketball players’ free throw performance decreased after ego-depletion, but when ego-depletion was followed by the mindfulness intervention, free throw performance was maintained at a level similar to the control group. Our results indicate that a brief mindfulness intervention mitigates the effects of ego depletion in a basketball free-throw task

Auditory and cognitive performance in elderly musicians and nonmusicians

Musicians represent a model for examining brain and behavioral plasticity in terms of cognitive and auditory profile, but few studies have investigated whether elderly musicians have better auditory and cognitive abilities than nonmusicians. The aim of the present study was to examine whether being a professional musician attenuates the normal age-related changes in hearing and cognition. Elderly musicians still active in their profession were compared with nonmusicians on auditory performance (absolute threshold, frequency intensity, duration and spectral shape discrimination, gap and sinusoidal amplitude-modulation detection), and on simple (short-term memory) and more complex and higher-order (working memory [WM] and visuospatial abilities) cognitive tasks. The sample consisted of adults at least 65 years of age. The results showed that older musicians had similar absolute thresholds but better supra-threshold discrimination abilities than nonmusicians in four of the six auditory tasks administered. They also had a better WM performance, and stronger visuospatial abilities than nonmusicians. No differences were found between the two groups\u2019 short-term memory. Frequency discrimination and gap detection for the auditory measures, and WM complex span tasks and one of the visuospatial tasks for the cognitive ones proved to be very good classifiers of the musicians. These findings suggest that life-long music training may be associated with enhanced auditory and cognitive performance, including complex cognitive skills, in advanced age. However, whether this music training represents a protective factor or not needs further investigation

Working Memory Training for Healthy Older Adults: The Role of Individual Characteristics in Explaining Short- and Long-Term Gains

Objective: The aim of the present study was to explore whether individual characteristics such as age, education, vocabulary, and baseline performance in a working memory (WM) task\u2014similar to the one used in the training (criterion task)\u2014predict the short- and long-term specific gains and transfer effects of a verbal WM training for older adults. Method: Four studies that adopted the Borella et al. (2010) verbal WM training procedure were found eligible for our analysis as they included: healthy older adults who attended either the training sessions (WM training group), or alternative activities (active control group); the same measures for assessing specific gains (on the criterion WM task), and transfer effects (nearest on a visuo-spatial WM task, near on short-term memory tasks and far on a measure of fluid intelligence, a measure of processing speed and two inhibitory measures); and a follow-up session. Results: Linear mixed models confirmed the overall efficacy of the training, in the short-term at least, and some maintenance effects. In the trained group, the individual characteristics considered were found to contribute (albeit only modestly in some cases) to explaining the effects of the training. Conclusions: Overall, our findings suggest the importance of taking individual characteristics and individual differences into account when examining WMtraining gains in older adults

Age Differences in Text Processing: The Role of Working Memory, Inhibition, and Processing Speed

Objectives. Age-related changes in the efficiency of various general cognitive mechanisms have been evoked to account for age-related differences between young and older adults in text comprehension performance. Using structural equation modeling, we investigate the relationship between age, working memory (WM), inhibition-related mechanisms, processing speed, and text comprehension, focusing on surface and text-based levels of processing. Methods. Eighty-nine younger (M = 23.11 years) and 102 older (M = 70.50 years) adults were presented text comprehension, WM, inhibition, and processing speed tasks. In the text comprehension task, the demand on the memory system was manipulated, by allowing (text present) or not (text absent) viewing the text during the answering phase. Results. As expected, age differences were larger when the text was absent. The best fitting model showed that WM mediated the influence of age on both text processing conditions, whereas age-related variance in WM was, in turn, accounted for by processing speed and inhibition. Discussion. These findings confirm the hypothesis that WM capacity explains age differences in text processing, while it is itself accounted for by the efficiency of inhibiting irrelevant information and by speed of processin

Emotion regulation, hope, and optimism during the third wave of the COVID-19 pandemic: The role of age and personality

Aims This study examined age-related differences between young and older adults' emotion regulation, hope, and optimism 1 year after the COVID-19 outbreak. Whether personality explained such outcomes was also examined. Method A sample of 228 young adults and 161 older adults was interviewed in April-May 2021 to complete questionnaires assessing cognitive reappraisal (CR) and expressive suppression (ES) emotion regulation strategies use, optimism, hope (agency and pathways components), and personality traits. Results Older adults reported greater CR and ES use, optimism, and hope-agency levels than young adults, whereas no age differences emerged for hope-pathway scores. Personality traits (more consistently emotional stability) contributed to explaining CR and ES use, and greater hopeful and optimistic dispositions. Conclusions These findings confirm older adults' advantage in facing the emotional and psychological fallout of the COVID-19 pandemic in its third wave. They also underscore the importance of considering personality to depict individual profiles prone to experiencing long-term negative emotional/psychological consequences of emergencies as COVID-19

Working memory and inhibitory control across the life span: Intrusion errors in the Reading Span Test

The aim of this study was to examine to what extent inhibitory control and working memory capacity are related across the life span. Intrusion errors committed by children and younger and older adults were investigated in two versions of the Reading Span Test. In Experiment 1, a mixed Reading Span Test with items of various list lengths was administered. Older adults and children recalled fewer correct words and produced more intrusions than did young adults. Also, age-related differences were found in the type of intrusions committed. In Experiment 2, an adaptive Reading Span Test was administered, in which the list length of items was adapted to each individual's working memory capacity. Age groups differed neither on correct recall nor on the rate of intrusions, but they differed on the type of intrusions. Altogether, these findings indicate that the availability of attentional resources influences the efficiency of inhibition across the life spa

Is working memory affective in dementia of alzheimer's type?

Abstract Background: The aim of the present study was to examine whether patients with Dementia of Alzheimer's Type (DAT) show a working memory emotional enhancement effect. Methods: We used a

Nearest transfer effects of working memory training: A comparison of two programs focused on working memory updating

This study analyzed the mechanisms involved in possible transfer effects for two different working memory updating (WMU) training programs administered to young adults and based on two updating paradigms: n-back and arithmetical updating. The influence of practice distribution on transfer effects was also explored by including two training regimens: massed and spaced practice. Performance on different WMU tasks more or less structurally similar to the tasks used in the training was assessed to analyze the nearest transfer effects. Near and far transfer effects were tested using complex working memory (WM) and fluid intelligence tasks. The results showed that the WMU training produced gains in only some of the WMU tasks structurally similar to those used in the training, not in those lacking the same structure, or in WM or fluid intelligence tasks. These limited nearest transfer effects suggest that gains could be due to the acquisition of a specific strategy appropriate for the task during the training rather than to any improvement in the updating process per se. Performance did not differ depending on the training regimen

Effects of an outdoor horticultural activities program on cognitive and behavioral functioning, mood, and perceived quality of life in people with dementia: a pilot study

IntroductionOne of various non-pharmacological treatments for people with dementia (PwD) is horticultural therapy. The aim of this double-blind, pre- and post-test, pilot study was to examine the effects of horticultural activities (HA) for PwD at a residential and daytime care facility. Whether combining HA with elements drawn from other psychosocial interventions (cognitive stimulation) would maximize any benefits was also newly examined.Materials and methodsTwenty-four PwD were involved either in HA, alone (TG1, N = 7) or combined with some cognitive stimulation (TG2, N = 8), or in indoor treatment-as-usual activities (CG, N = 9). Benefits were assessed in terms of general cognitive functioning (for participants with mild-to-moderate dementia), mood, behavioral and psychological symptoms, and quality of life.ResultsNo differences emerged between TG1 and TG2 in any outcome measure, so the two groups were combined (N = 15). Compared with the CG, the TG involved in HA exhibited less frequent and severe behavioral and psychological symptoms and an improved mood after the intervention. Caregivers also reported less distress in the TG after the intervention than in the CG. Considering only PwD with mild-to-moderate dementia, the TG also showed benefits in a measure of general cognitive functioning, and self-reported quality of life, compared with the CG.DiscussionOur results further confirm that engaging PwD in participatory HA in contact with natural elements can decrease their dementia symptoms and their caregivers’ distress, but also increase PwD’s quality of life. Our findings also suggest the need to consider dementia severity when assessing the benefits of horticultural therapy
