“…Some studies have reported that age does not interact with delay in terms of performance quality (e.g., Charness & Campbell, 1988; Hulicka & Weiss, 1965; Hultsch & Dixon, 1983; Hultsch, Hertzog, & Dixon, 1984; Meyer, Young, & Bartlett, 1989; Salthouse & Somberg, 1982). Other studies have found that performance disproportionately degrades over the delay interval for older adults compared to young adults (e.g., Cohen & Faulkner, 1984; Harwood & Naylor, 1969; Hulicka & Rust, 1964; Jamieson, 1971; Park, Royal, Dudley, & Morell, 1988). One potential explanation for the inconsistent findings may be different learning (in either degree or kind) between young and old adults on the target task.…”
