The present study was conducted to expand research showing that older adults' expectations that they will recall particular medication instructions do not coincide with their actual ability to do so. Seventy-one younger-old adults (M=68.10 years, range=57-74) and 62 older-old adults (M=80.31 years, range=75-89) made judgements about the likelihood of their recalling medication instructions and about their confidence in their recall. The results indicate that older-old adults recall fewer instructions than do younger-old adults and that both groups overestimate their ability to recall the instructions. This research suggests that problems remembering to take medication may be due, in part, to older adults' overestimating the ease with which they will remember medication instructions.
