Reward motivation more consistently modulates memory for younger compared to older adults in a directed forgetting task.

Remembering and forgetting are both important processes of a healthy memory system, but both processes can show age-related decline. Reward anticipation is effective at improving remembering in both younger and older adults, but little is known about the effects of incentives on forgetting. In four online experiments, we examined whether reward motivation modulates intentional remembering and forgetting in younger and older adults, and systematically varied the presentation of reward cues during encoding to test whether the temporal dynamics of reward anticipation are important for directed forgetting performance.

Behavioral and fMRI evidence that arousal enhances bottom-up selectivity in young but not older adults.

The locus coeruleus-noradrenergic system integrates signals about arousal states throughout the brain and helps coordinate cognitive selectivity. However, age-related changes in this system may impact how arousal coordinates selectivity in older adults. To examine this, we compared how increases in emotional arousal modulates cognitive selectivity for images differing in perceptual salience in young and older adults.

An integration engineering framework for machine learning in healthcare.

Background And Objectives: Machine Learning offers opportunities to improve patient outcomes, team performance, and reduce healthcare costs. Yet only a small fraction of all Machine Learning models for health care have been successfully integrated into the clinical space. There are no current guidelines for clinical model integration, leading to waste, unnecessary costs, patient harm, and decreases in efficiency when improperly implemented.

Cognitive and Psychosocial Outcomes of Self-Guided Executive Function Training and Low-Intensity Aerobic Exercise in Healthy Older Adults.

Objectives: Prior work has demonstrated that executive function training or physical exercise can improve older adults' cognition. The current study takes an exploratory approach to compare the feasibility and efficacy of online executive function training and low-intensity aerobic exercise for improving cognitive and psychosocial functioning in healthy older adults.

Method: Following a standard pretest-training-posttest protocol, 40 older adults (aged 65 and above) were randomly assigned to an executive function or a physical training group.

Influence of Reward Motivation on Directed Forgetting in Younger and Older Adults.

An important feature of the memory system is the ability to forget, but aging is associated with declines in the ability to intentionally forget potentially due to declines in cognitive control. Despite cognitive deficits, older adults are sensitive to affective manipulations, such as reward motivation, and reward anticipation can improve older adults' memory performance. The goal of the current studies was to examine the effect of reward motivation on directed remembering and forgetting.

Age differences in vulnerability to distraction under arousal.

Aging affects brain circuitry involved in both inhibition and arousal. In this study, we tested whether older adults are more or less prone to distraction from emotionally arousing events than young adults. To do so, we examined how arousing taboo distractor words affected concurrent 1-back task performance and subsequent memory for distractors.

The effect of emotional distraction on hyper-binding in young and older adults.

Our cognitive system implicitly binds relevant stimulus features into a coherent episodic event. According to past research, relative to young adults, older adults are more likely to hyper-bind extraneous co-occurrences and tend to prioritise positive over negative information. However, the interaction of these cognitive and emotional processes is unknown.

Retracted: The Effect of Bilingualism on Older Adults' Inhibitory Control: A Meta-Analysis.

Background And Objectives: The effect bilingualism has on older adults' inhibitory control has been extensively investigated, yet there is continued controversy regarding whether older adult bilinguals show superior inhibitory control compared with monolinguals. The objective of the current meta-analysis was to examine the reliability and magnitude of the bilingualism effect on older adults' inhibitory control as measured by the Simon and Stroop tasks. In addition, we examined whether individual characteristics moderate the bilingual advantage in inhibition, including age (young-old vs old-old), age of second language acquisition, immigrant status, language proficiency, and frequency of language use.

Age differences in cue utilization during prospective and retrospective memory monitoring.

Memory monitoring is an inferential process that we use to evaluate and make judgments about the contents of our memory. Prior work has shown age-related similarity in prospective monitoring of ongoing memory processes, but age-related deficits when retrospectively monitoring the source of memories. In the current study, we examined how extrinsic and intrinsic cues influence age differences in these 2 forms of memory monitoring.

Age differences in the neural correlates underlying control of emotional memory: An event-related potential study.

The ability to selectively remember important information and forget irrelevant details is fundamental to successful memory. Research has shown that both younger and older adults can intentionally remember and forget information varying in emotional valence; however, whether the neural correlates of these processes change with age is unknown. In this event-related potential (ERP) study, we sought to fill this knowledge gap using the item-directed forgetting (DF) task.

Stereotype Threat Effects on Older Adults' Episodic and Working Memory: A Meta-Analysis.

Background And Objectives: Prior research has shown that exposure to negative age-based stereotype threat (ST) can undermine older adults' memory performance. The objective of the current meta-analysis was to examine the reliability and magnitude of ST effects on older adults' episodic and working memory performance-two forms of memory that typically show the greatest age-related declines. In addition, we examined potential moderators of age-based ST including type of ST manipulation, type and timing of memory task, participant age and education level.

The Role of Cognition, Personality, and Trust in Fraud Victimization in Older Adults.

Older adults are more at risk to become a victim of consumer fraud than any other type of crime (Carcach et al., 2001) but the research on the psychological profiles of senior fraud victims is lacking. To bridge this significant gap, we surveyed 151 (120 female, 111 Caucasian) community-dwelling older adults in Southern Ontario between 60 and 90 years of age about their experiences with fraud.

Local context effects during emotional item directed forgetting in younger and older adults.

This paper explored the differential sensitivity young and older adults exhibit to the local context of items entering memory. We examined trial-to-trial performance during an item directed forgetting task for positive, negative, and neutral (or baseline) words each cued as either to-be-remembered (TBR) or to-be-forgotten (TBF). This allowed us to focus on how variations in emotional valence (independent of arousal) and instruction (TBR vs.

Neural modulation of directed forgetting by valence and arousal: An event-related potential study.

Intentional forgetting benefits memory by removing no longer needed information and promoting processing of more relevant materials. This study sought to understand how the behavioural and neurophysiological representation of intentional forgetting would be impacted by emotion. We took a novel approach by examining the unique contribution of both valence and arousal on emotional directed forgetting.

Mindfulness meditation practice and executive functioning: Breaking down the benefit.

This paper focuses on evidence for mindfulness meditation-related benefits to executive functioning, processes important for much of human volitional behaviour. Miyake et al. (2000) have shown that executive functions can be fractionated into three distinct domains including inhibition, working memory updating, and mental set shifting.

Evaluating Intention and Effect: The Impact of Healthcare Facility Design on Patient and Staff Well-Being.

Objective: This post occupancy evaluation (POE) assessed the impact of architectural design on psychosocial well-being among patients and staff in the context of a new complex continuing care and rehabilitation facility.

Background: Departing from typical POEs, the hospital design intentions formed the theoretical basis to assess outcomes. Intentions included creating an environment of wellness; enhancing connection to the community, the city, and nature; enhancing opportunities for social interaction; and inspiring activity.

Positivity effect in source attributions of arousal-matched emotional and non-emotional words during item-based directed forgetting.

Consistent with their emphasis on emotional goals, older adults often exhibit a positivity bias in attention and memory relative to their young counterparts (i.e., a positivity effect).
