“…The only other criterion that has received a large amount of empirical study states that there should be no developmental trends. Some studies have found a null effect of age (e.g., Attig & Hasher, 1980; Hasher & Chromiak, 1977; Hasher & Zacks, 1979, Experiment 1; Kausler & Puckett, 1980), but others have found strong effects of age on memory for frequency (Ghatala & Levin, 1973; Johnson, Raye, Hasher, & Chromiak, 1979; Kausler et al, 1984; Kausler, Wright, & Hakami, 1981, Lund, Hall, Wilson, & Humphreys, 1983, Warren & Mitchell, 1980). There is no obvious way to resolve the discrepancies in these studies.…”
