Study Summary

Forgetfulness is a common complaint among middle and older adults, with the vast majority of these complaints not rooted in established causes or diagnoses. The contents of these subjective cognitive complaints (SCC) include difficulty retrieving specific words (e.g., names of people or places), misplacing common items (e.g., keys or eyeglasses), and prospective memory failures (e.g., forgetting appointments and reasons for entering a room). One study found that 54% of people in a sample composed of 15,000 adults over the age of 55 reported that they had some difficulty remembering things over the past year. In the subsample composed of individuals aged 85+, this figure increased to 62%. While some experiences of forgetting can be partially explained by age-related cognitive decline, problems with retrieval processes can be attributed to a host of other factors including stress and anxiety, lack of sleep, and side effects from medications. Even with all of these other possible aspects at play, older adults tend to attribute everyday instances of forgetting to uncontrollable factors including age. Moreover, while society tends to associate forgetting with the elderly population, young adults also report the experience of forgetting. There is reason to suspect that while older adults tend to experience more instances of forgetting than they did as younger adults, they also pay more attention to instances of forgetting, gathering evidence that they are declining. Every instance of forgetting can confirm that one is in the midst of decline. This process is a type of confirmation bias: Every time an older adult notices an instance of forgetting, he/she confirms that the self fits within the larger negative age stereotype. The present study investigates the Attention to Variability Paradigm. Specifically the participants will pay attention to how memory performance fluctuates throughout the day. Primary outcomes will be memory efficacy beliefs and memory performance on a

Primary Outcome

This 13-item self-report scale measures subjective memory failures. Namely, respondents are asked to indicate whether or not they had experienced certain memory failures within the past 24 hours (e.g., "Did you find that a word was "on the tip of your tongue" - you knew what it was but could not quite find it?). Following the 13 yes/no questions about one's memory functioning, participants are asked to rate how stressful these failures are on a scale of 0-10 with 0 indicating "not at all stressf
