Effects of target set size on feelings of knowing and cued recall: Implications for the cue effectiveness and partial-retrieval hypotheses

Target set sire refers to the number of preexisting connections a studied word has to closely related concepts in long-term memory. The purpose of this investigation was to determine whether target set size influences feeling-of-knowing (FOK) ratings. The results showed that ratings were higher for targets connected to smaller sets, as compared with those connected to larger sets. Comparable effects were obtained with the use of different encoding strategies, including concreteness classifications and vowel naming, and with both meaningfully and phonologically related test cues. These findings indicate that FOKs are sensitive to competition between concepts linked to the target and that this sensitivity is independent of encoding strategy and type of test cue. Response time measures indicated that FOKs are sensitive to competition that arises when concepts are activated in parallel, whereas recall is more sensitive to competition that arises during sampling associated with search. Implications for various cue-based and target-based explanations of FOK effects are discussed.
