This work explores how we track and adjust our knowledge about word meanings as instances of a word are encountered, with particular focus on the role of sleep in this process. In Experiment 1, participants encountered low-ambiguity words (e.g., bathtub) in sentences that biased their meanings towards a specific interpretation (e.g., bathtub-slip vs. bathtub-relax). In Experiment 2, participants encountered word-class ambiguous words (e.g., loan) in sentences where the words were used in their dispreferred word class (e.g., “He will loan me money”). Both experiments showed that such sentential experience influenced later interpretation and usage of the words more after a night’s sleep than a day awake

We interpret these results as evidence for a general role of episodic memory in language comprehension such that new episodic memories are formed every time a sentence is comprehended, and these memories contribute to lexical processing next time the word is encountered, as well as potentially to the fine-tuning of long-term lexical knowledge.

New Paper: The Interaction between the two Languages of Bilingual Speakers

This priming study was led by Dr Eva Poort, looking at how very recent experience with words (including cognates and interlingual homographs) in the L2 of Dutch-English bilinguals influenced their processing of related words in their L1.

This work follows up earlier work by Eva on this topic:

New Paper: Word-meaning priming extends beyond homonyms

This paper, which was led by Adam Curtis (Univeristy of York) as part of an ESRC grant awarded to Prof Gareth Gaskell (York) and Prof Jenni Rodd (UCL) has been published in Cognition and can be accessed here.

In three pre-registered experiments, participants were exposed to non-homonym targets (e.g., “balloon”) in sentences that biased interpretation towards a specific aspect of the word’s meaning (e.g., balloon‑helium vs. balloon-float). After a ~ 10–30 min delay access to the primed aspect of the word’s meaning was enhanced.

These findings show that similar ‘word-meaning priming’ effects, that had previously only been shown for homonyms (e.g., bark-dog vs bark-tree) are far more general than previously thought, and sugest that episodic sentence memory plays a key role in comprehension.

New Paper: Dominance Norms for Spoken Ambiguous Words in British English

Becky Gilbert and Jenni Rodd have published set of dominance norms for ambiguous words in the Journal of Cognition. These were produced by collating data from across a number of different experiments to construct a dataset of 29,542 data points for 243 spoken ambiguous words from UK participants.

This includes resources to help other researchers code word-association responses to ambiguous words in a semi-automated manner, saving researcher time and improving coding consistency. We hope that researchers will add their own data to this database further improving the precision of our dominance estimates.
