Elusive Gains of Cognitive Training: Limited Effects on Neural Activity Across Sessions.

Background/objectives: Cognitive training paradigms rely on the idea that consistent practice can drive neural plasticity, improving not only connectivity within critical brain networks, but also ultimately result in overall enhancement of trained cognitive functions, irrespective of the specific task. Here we opted to investigate the temporal dynamics of neural activity and cognitive performance during a structured cognitive training program.

Methods: A group of 20 middle-aged participants completed 20 training sessions over 10 weeks.

A tale of two ages: fluid reasoning as a predictor of working memory training efficacy in middle-aged and older adults.

Research on working memory (WM) training reveals significant variability in training effects, indicating that pretraining cognitive abilities might account for these differences. However, consensus on whether higher (magnification account) or lower (compensation account) pretraining abilities predict greater training effects remains elusive. Our study aimed to clarify the role of fluid reasoning in predicting training performance (i.

Don't disturb my circles: The effect of fine arts training on visuospatial ability in students.

Origami, drawing and colouring are artistic activities that can be beneficial for cognitive abilities or emotional well-being. However, there is a lack of studies that would investigate and compare these activities and their effects within the spatial abilities' domain. The aim of this study was to investigate if and how participating in three artistic activities-colouring, drawing or origami-can enhance spatial abilities.

The brief case for everyday problems: a proposal of two brief alternate forms of the Everyday Problems Test.

Everyday Problems Test (EPT; Willis and Marsiske, Manual for the everyday problems test, Pennsylvania State University, Pennsylvania, 1993) is an 84-item performance-based measure of older adults' everyday cognitive competencies in seven everyday domains (e.g., finance, reading prescription).

"I Did My Own Research": Overconfidence, (Dis)trust in Science, and Endorsement of Conspiracy Theories.

Epistemically suspect beliefs, such as endorsement of conspiracy theories or pseudoscientific claims, are widespread even among highly educated individuals. The phenomenon of conspiratorial thinking is not new, yet the COVID-19 pandemic, causing a global health crisis of an unprecedented scale, facilitated the emergence and rapid spread of some rather radical health-related pseudoscientific fallacies. Numerous correlates of the tendency to endorse conspiracy theories have already been addressed.

The higher, the better: Cognitive reserve contributes to lifestyle activities in older age.

The study aimed at investigating age and gender differences in cognitive reserve (CR) and whether CR can contribute to everyday and physical activity and fluid reasoning in older adults. Participants ( = 294), categorized into three age groups: young-old, middle-old, and old-old, completed the Cognitive Reserve Index questionnaire (CRIq), the Everyday Activity Questionnaire (EAQ), the Physical Activity Scale for the Elderly (PASE), and the Unbalanced Structure Test (UST). The old-old had significantly lower scores on CRI-Total, CRI-Working activity, and CRI-Leisure time compared to young-old and middle-old.

Trust in Science, Perceived Vulnerability to Disease, and Adherence to Pharmacological and Non-pharmacological COVID-19 Recommendations.

Protection motivation theory (PMT) is a theoretical framework informative for understanding behavioral intentions and choices during exceptional and uncommon circumstances, such as a pandemic of respiratory infectious disease. PMT postulates both the threat appraisal and the coping appraisal as predictors of health behaviors. Recent advances in the field of behavioral immune system (BIS) research suggest that humans are equipped with a set of psychological adaptations enabling them to detect the disease-threat and activate behavioral avoidance of pathogens.

Mental imagery training in older adults: Which are benefits and individual predictors?

Objectives: Strategic memory training involves explicit instructions in mnemonic methods to improve recall. Mental imagery is considered among the most effective encoding strategies. The aim of the present study was to assess the benefits of a strategic memory training based on mental imagery (originally proposed by Carretti et al.

Functions of Autobiographical Memory in Younger and Older Adults.

Functional approach to autobiographical memory (AM) posits its three broad functions: directive, self, and social. Although these functions are probably universal, life stage and gender variations are expected. This research builds on previous studies investigating the validity of Thinking About Life Experiences Questionnaire (TALE; Bluck and Alea, 2011).

Computerized tabletop games as a form of a video game training for old-old.

This research aimed at investigating the utility of a computerized version of a cognitively stimulating activity as a video game intervention for elderly. The study focused on the effect of a 6-week extensive practice intervention on aspects of cognitive functioning (vigilance, working memory (WM), inhibition, reasoning) of old-old participants (N = 29), randomly assigned to trained or active control group. The difference between groups was in the content of the extended video game practice - cognitively complex card game for trained and computerized version of a simple dice-game of chance for control participants.

The Efficacy of a Dance Intervention as Cognitive Training for the Old-Old.

This research investigates the efficacy of a dance intervention of moderate length (10 weeks, 45 min/week) on a sample of old-old adults living in a residential care setting. The study focused on the effect of the intervention on aspects of cognitive functioning (short-term memory, executive functioning). In addition, changes in general self-efficacy and life satisfaction were investigated.

The efficacy of a multifactorial memory training in older adults living in residential care settings.

Background: Several studies have shown an increase in memory performance after teaching mnemonic techniques to older participants. However, transfer effects to non-trained tasks are generally either very small, or not found.

Methods: The present study investigates the efficacy of a multifactorial memory training program for older adults living in a residential care center.

Self-evaluation of memory systems: development of the questionnaire.

Objectives: The term metamemory refers to the knowledge one has about the development and use of memory in general, and one's own memory processes in particular. The current theoretical perspective on memory processes is best described by the memory systems framework which represents a useful tool in specifying different 'kinds' of memory. We present here the Self-evaluation of Memory Systems Questionnaire (SMSQ), which assesses the multidimensional construct of metamemory based on the memory systems framework.

Content-specific activational effects of estrogen on working memory performance.

The authors explored the influence of task content and the menstrual cycle phase on working memory (WM) performance. They addressed the content specificity of WM in the framework of evolutionary psychology, proposing a hormone-mediated adaptive design governing face perception. The authors tested 2 groups of healthy young women (n = 66 women with regular menstrual cycle, n = 27 oral contraceptive users) on a WM task with adult male or infant face photographs.

Femininity and masculinity across the menstrual cycle: a relation to mate value.

Numerous studies have shown that menstrual cycle related variations in sex hormones influence various cognitive processes. These shifts are considered as the evidence for a hormone-mediated adaptive design underlying human mating motivation. In a series of related studies we have shown that (i) femininity does not vary across the menstrual cycle, whereas masculinity is the most pronounced during the fertile period, (ii) masculinity, but not femininity, predicts shifts in spatial cognition across the menstrual cycle, and (iii) women with different positions on masculinity and femininity dimensions differ in their self-perceived mate value.
