When is literal meaning inhibited? Evidence from nonsense in the metaphor-induced lexical forgetting paradigm

A common feature of metaphoric language processing is a conflict between literal and figurative aspects of meaning. A consequence of this is the need to select the most appropriate meaning among competing associates when we encounter such phrases. The goal of the present experiments was to adapt the "impossible" retrieval approach of previous retrieval-induced and problem-solving-induced forgetting (RIF; PSIF) studies to test for the use of inhibitory mechanisms during metaphor comprehension. To achieve this goal, a series of 3 studies assessed forgetting following the processing of nonsense metaphors that were unlikely to lead to viable interpretations within a short period of time (Jealousy is a barn). In the first 2 experiments, processing nonsense metaphors led to reduced recall for previously studied literal associates. In a 3rd study, processing nonsense metaphors led to longer recognition latencies for literal associates on a cue-independent task. In contrast, no evidence of forgetting was seen because of the processing of familiar metaphors in any study. Because participants are unlikely to reach a viable interpretation of these nonsense metaphors, and because results were similar using recall and cue-independent recognition measures, these results provide novel support for an inhibitory account for this forgetting effect over a blocking or cue-based interference account.
