简要总结
Evaluates an intervention designed to improve everyday memory function, contrasting people receiving the intervention with a group that receives traditional memory strategy training.
详细描述
This project seeks to develop and validate a novel approach to training everyday memory functioning in older adults. The approach (1) trains people to use simple but effective memory skills that have broad applicability in everyday life and (2) shapes a set of skills and habits of mind that will increase the likelihood of effective use of skills and memory aids. It is based on a metacognitive perspective on self-regulation in cognitively demanding situations and informed by recent theories about how suboptimal habit patterns can be altered. The approach has not yet been used in an everyday memory intervention in high-functioning, community-dwelling older adults. The proposed research validates ecological momentary assessment methods to get actual behavioral measures of forgetting in everyday life. It then uses these procedures in a randomized experiment that contrasts the everyday memory intervention group with a traditional memory-strategy training group. The hypothesis is that the everyday memory training intervention will reduce everyday memory errors and memory complaints, whereas the memory strategy training will alter strategy use and memory performance, with little cross-over effect. The hypothesized pattern will establish the explicit benefits of our everyday memory intervention procedures and demonstrate the limitation of standard memory training for that purpose.

结局指标
主要结局
Everyday Cognition Simulation Task: ATM Task (Number of Errors)
时间窗: posttest only
Computerized task to simulate use of an ATM machine. Measure: number of errors
Everyday Memory Failures
时间窗: minimum 8 day period after training on app prior to posttest
Across the data collection period, participants audio recorded descriptions of their memory failures on a smartphone app. The audio recordings were transcribed and then cleaned and qualitatively coded so that the number of memory failures each participant reported during the data collection period could be counted. The data was qualitatively coded to ensure an accurate count of the number of memory failures per participant without counting duplicate events or accidental reports. Average daily number of reported memory failures from EMA \& daily diaries is reported.
Free Recall Test
时间窗: pretest and posttest (approximately 1 month lag)
Computerized task to present 30 concrete nouns, 6 from 5 taxonomic categories (Hultsch, Hertzog, Dixon, \& Small, 1998) Measure is proportion of 30 words recalled
Everyday Cognition Simulation Task: ATM Task (Time in Seconds)
时间窗: posttest only
Computerized task to simulate use of an ATM machine. Measure: time to complete task (in seconds)
Associative Recall Test
时间窗: pretest and posttest (approximately 1 month lag)
Computerized task to present 40 concrete-concrete associatively unrelated noun pairs (Hertzog, Sinclair, \& Dunlosky, 2010) Outcome is proportion of 40 words correctly recalled.
Prospective Memory Lab Contact Efficiency
时间窗: Two weeks prior to posttest
median absolute time deviation (in minutes) from scheduled lab contact for completed contacts
Czaja Everyday Cognition Simulation Task: Prescription Refill Task (Number of Errors)
时间窗: posttest only
Computerized task to simulate use of an automated telephone program to refill prescriptions. Measure: Number of errors
