Title: Retuning of Lexical-Semantic Representations: Repetition and Spacing Effects in Word-Meaning Priming.

Authors: Hannah N. Betts, Rebecca A. Gilbert, Zhenguang G. Cai, Zainab B. Okedara, & Jennifer M. Rodd

Abstract:

Current models of word-meaning access typically assume that lexical-semantic representations of ambiguous words (e.g., ‘bark of the dog/tree’) reach a relatively stable state in adulthood, with only the relative frequencies of meanings and immediate sentence context determining meaning preference. However, recent experience also affects interpretation: recently encountered word-meanings become more readily available (Rodd et al., 2016, 2013). Here, 3 experiments investigated how multiple encounters with word-meanings influence the subsequent interpretation of these ambiguous words. Participants heard ambiguous words contextually-disambiguated towards a particular meaning and, after a 20- to 30-min delay, interpretations of the words were tested in isolation. We replicate the finding that 1 encounter with an ambiguous word biased the later interpretation of this word towards the primed meaning for both subordinate (Experiments 1, 2, 3) and dominant meanings (Experiment 1). In addition, for the first time, we show cumulative effects of multiple repetitions of both the same and different meanings. The effect of a single subordinate exposure persisted after a subsequent encounter with the dominant meaning, compared to a dominant exposure alone (Experiment 1). Furthermore, 3 subordinate word-meaning repetitions provided an additional boost to priming compared to 1, although only when their presentation was spaced (Experiments 2, 3); massed repetitions provided no such boost (Experiments 1, 3). These findings indicate that comprehension is guided by the collective effect of multiple recently activated meanings and that the spacing of these activations is key to producing lasting updates to the lexical-semantic network.

We are pleased to announce that The Word Lab’s Eva Poort has been awarded one of the Open Science Framework’s (OSF’s) $1000 prizes for the Preregistration Challenge!

The prize was awarded for Eva’s article entitled ‘The cognate facilitation effect in bilingual lexical decision is influenced by task demands’ (Experiment 2 of the paper was preregistered through the Open Science Framework).

Eva was previously interviewed about her first experience of preregistration, you can read the interview in full here: The “Preregistration Challenge” – Interview with Eva Poort.
