From tip-of-the-tongue (TOT) data to theoretical implications in two steps: when more TOTs means better retrieval.
Two experiments in which participants named pictured objects with difficult or easier names, and a reanalysis and review of published data, reveal that problematic measures used in previous studies obscured the implications of group differences in tip-of-the-tongue (TOT) rates. In Experiment 1, increased age led to more TOTs for difficult but not easy targets. In Experiment 2, bilinguals had more TOTs than monolinguals for easy targets but fewer TOTs for difficult targets. The authors developed a theoretically motivated measure that clarifies the implications of TOT data by linking all responses elicited in the TOT paradigm with either success or failure in completing 2 retrieval steps in current models of language production. The 2-step analysis reveals a common mechanism for the age and bilingualism effects and implies that age has both positive and negative effects on retrieval.
