Table 7.

Average Memory Lapses and Daily Impacts Divided by Decade in EAS.

Variables of interest, M (SD)	70–79 Years (n = 155)	80–89 Years (n = 52)	90–93 Years (n = 2)
Prospective memory lapses	.47 (.57)	.38 (.50)	0
Prospective irritation	33.19 (22.81)	28.52 (20.99)	0
Prospective interference	19.66 (18.11)	15.86 (14.95)	0
Retrospective memory lapses	.56 (.56)	.52 (.49)	.18 (.11)
Retrospective irritation	33.09 (22.37)	32.25 (21.11)	0
Retrospective interference	18.87 (18.28)	18.78 (16.00)	2.00 (1.41)

Note. Prospective Memory Lapses ranged from 0 to 3, Retrospective Memory Lapses ranged from 0 to 4. For both RM and PM lapses, daily impact (i.e., irritation and interference) were scored from 0 to 100. EAS = Einstein Aging Study.
