Does using a foreign language reduce mental imagery?

Montero-Melis, G., Isaksson, P., Van Paridon, J., & Ostarek, M. (2020). Does using a foreign language reduce mental imagery? Cognition, 196: 104134. doi:10.1016/j.cognition.2019.104134.
In a recent article, Hayakawa and Keysar (2018) propose that mental imagery is less vivid when evoked in a foreign than in a native language. The authors argue that reduced mental imagery could even account for moral foreign language effects, whereby moral choices become more utilitarian when made in a foreign language. Here we demonstrate that Hayakawa and Keysar's (2018) key results are better explained by reduced language comprehension in a foreign language than by less vivid imagery. We argue that the paradigm used in Hayakawa and Keysar (2018) does not provide a satisfactory test of reduced imagery and we discuss an alternative paradigm based on recent experimental developments.
