Engagement in cognitively demanding everyday activities has been shown to benefit cognitive health in later life. We investigated the factors that influence engagement, with specific interest in determining the extent to which the costs of engaging cognitive resources are associated with intrinsic motivation and, ultimately, participation in everyday activities. Older adults (N = 153) aged from 65 to 81 years completed a challenging cognitive task, with the costs of cognitive engagement-operationalized as the effort required to maintain performance-assessed using systolic blood pressure responses (SBP-R). We also assessed participation in everyday activities using both 2-year retrospective reports and five daily reports over a 5-week period. Structural models revealed that lower levels of costs were associated with more positive attitudes about aging, which in turn were associated with higher levels of intrinsic motivation. Motivation was subsequently predictive of everyday activity engagement, with the effect being specific to those activities thought to place demands on cognitive resources. The measure of engagement had minimal impact on the nature of the observed effects, suggesting that the retrospective and weekly assessments were tapping into similar constructs. Taken together, the results are consistent with expectations derived from Selective Engagement Theory (Hess, 2014), which argues that engagement in demanding activities is related to the cost associated with such engagement, which in turn leads to selective participation through changes in motivation.

Activity that places demands on cognitive resources has positive effects on cognitive health in old age. To further understand determinants of age-group differences in participation, we examined how negative aging stereotypes and responses associated with a cognitively challenging activity influenced future willingness to engage in that activity. Sixty-nine young (20–40 years) and 80 older (63–84 years) adults performed a letter-number sequencing (LNS) task at different levels of demand for 15 min, during which systolic blood pressure responses—a measure of effort mobilization—and subjective perceptions of task demands were assessed. Approximately half the participants were primed with a negative aging stereotype prior to this task. Following the LNS task, participants completed an effort-discounting task, with resulting subjective values indicating their willingness to perform the task at each level of demand. As expected, both subjective and objective indicators of cognitive demands as well as performance were associated with future willingness to engage in a difficult task, with these effects being significantly greater for older adults. In addition, although stereotype activation influenced older adults’ engagement levels in the LNS task, it did not moderate willingness. Together, the results indicate that, relative to younger adults, older adults’ decisions to engage in cognitively challenging activities are disproportionately affected by their subjective perceptions of demands. Interestingly, actual engagement with the task and associated success result in reduced perceptions of difficulty and greater willingness to engage. Thus, overcoming faulty and discouraging task perceptions may promote older adults’ engagement in demanding but potentially beneficial activities.

Objectives: Some research suggests that older adults have a tendency to be biased toward positive information, but may be more willing to attend to potentially beneficial negative information in certain situations. Following the mood-as-resource framework, one possibility is that older adults may be more willing to consider negative information when in a positive mood, with positive affect serving as a buffer to the adverse emotional consequences that may follow. Method: Young (n = 62) and older (n = 65) adults completed a difficult cognitive task before completing either a positive or negative experience recall task, depending upon assigned condition. Afterwards, they rated their interest in viewing their strengths and weaknesses on the previously completed task, and then selected and viewed different types of feedback (i.e., strengths or weaknesses). Results: Older adults in the positive condition selected more weaknesses to view and spent more time viewing weaknesses than older adults in the negative condition. There were no differences across conditions in behavioral results for young adults. Ratings of interest in viewing different types of feedback did not correspond with actual feedback viewing behavior. Discussion: Results highlight the importance of considering older adults' pre-existing mood before addressing self-relevant information that may be negative but important.

The impact of aging stereotypes on task engagement was examined. Older adults (N = 144, ages 65 to 85) were exposed to primes designed to activate positive or negative stereotypes about aging, with half of the individuals in each stereotype group also assigned to a high-accountability condition to enhance motivation. Participants performed a memory-scan task comprising 2 levels of demands (memory sets of 4 or 7 items), with 2 blocks (5 min each) at each level. Systolic blood pressure recorded throughout the task was used to monitor engagement levels. High accountability was associated with greater engagement at the highest level of task demands. Negative stereotype activation also resulted in elevated engagement levels, but only during the initial trial blocks in the high-accountability condition. Lowest levels of engagement were associated with low accountability, with no difference between stereotype conditions. An analogous differential analysis on these same data using need for cognition and attitudes toward aging as measures of motivation and stereotypes revealed similar trends. Specifically, negative aging attitudes were associated with elevated levels of engagement only in individuals who were high in intrinsic motivation, with the effects greatest at the highest levels of task demands. The results provide a more nuanced perspective on the impact of negative aging stereotypes than suggested in previous research, with the impact on behavior moderated by situational and personal factors associated with motivation. Although potentially negative in the long run, elevated cardiovascular responses indicative of task engagement may represent an adaptive response to support performance. (PsycINFO Database Record

Background Previous research (Hess, Popham, Dennis, & Emery, 2013) suggested that age-based positivity effects in memory were attenuated with social stimuli. We examined the degree to which this generalized across arousal levels associated with social images. We also examined variations in approach and avoidance responses to images, and how these were differentially related to memory in younger versus older adults. Methods In Experiment 1, young (22 – 43 years) and older (65 – 85 years) adults recalled positive and negative social scenes that were high or low in arousal. In Experiment 2, young (20 – 40 years) and older (65 – 83 years) adults viewed and recalled the same scenes under instructions designed to alter arousal, and approach and avoidance ratings for each image were recorded. Results In Experiment 1, age differences in recall were confined to high-arousal, negative images, with young adults exhibiting superior memory relative to older adults. There was no evidence of an age-related positivity effect for low arousal social scenes. This result was replicated in Experiment 2, but distancing instructions minimized the age difference in recall for high-arousal, negative images. Approach and avoidance ratings differentially predicted recall across age groups, with stronger associations in the young. Conclusion The results are consistent with emerging evidence demonstrating that valence-based biases associated with aging (e.g., positivity effect) are specific to the context and stimulus characteristics. Differences in prediction of recall responses from approach and avoidance ratings across age groups suggested that the observed effects in memory reflected differences in responses to the characteristics of stimuli.
