The effect was observed using semantically related primes (e.g. dog-CAT) and associated with an increased contribution of either familiarity (i.e. recognition without recall of encoding context), or recollection (i.e. retrieval of encoding details). Such difference could be explained by the variability of the semantic relation between words (taxonomic, attributes, context, …) whereas thematic (brush-HAIR) and taxonomic (lion-TIGER) relationships are particularly salient. In this study, the impact of thematic and taxonomic primes was contrasted and the contribution of recollection and familiarity was assessed using the Remember-Know-Guess paradigm (Tulving, 1985). The word recognition task was performed by 30 adults (24.6±4.5 yo) in 3 blocks varying the nature of the prime (repetition; taxonomic; thematic), each presented with a word-learning phase (32 words) and a ‘yes-no’ recognition task with 32 ‘old’ and 32 ‘new’ words. A masked 33ms word either related or unrelated preceded each test word. Results showed a significant interaction between the type of words (new; old) and the priming context (related; unrelated) for the proportion of ‘yes’ and ‘know’ responses. More ‘yes’ and ‘know’ responses following a related prime (versus unrelated) occurred for false alarms only. Such effect was observed across all conditions, supporting the idea that strict control of the type of conceptual priming (as opposed to all-out priming) leads to an enhanced feeling of familiarity for unstudied words in the same way as repetition priming.
