Clarifying the role of inhibitory control in L2 phonological processing: A preregistered, close replication of Darcy et al. (2016)

Abstract

Abstract Darcy et al. (2016) examined the relationship between language abilities and general cognition, or specifically, how inhibitory control might relate to L2 speech perception and production. Given that their findings unexpectedly indicated a stronger relationship between inhibitory control and perception in comparison to inhibitory control and production, and because inhibitory control was measured using a single, retrieval-induced inhibition task, the current study is a close replication with the inclusion of two additional tasks of intentional inhibition: the Stroop task and the Simon task. A comparison of the descriptive statistics for the tests of phonological processing and retrieval-induced inhibition between the initial study and current replication indicated negligible differences between the two participant samples. However, results of the partial correlation analyses in the current replication did not indicate clear relationships between phonological variables and inhibitory control. Possible explanations for the different patterning of results and implications for future replications are discussed.
