Subclaims¶

q2 i? Performance is worse on ABA than CBA language sequences, explained by persisting reactive inhibition of the non-target language. → Mathieu Declerck & Andrea M. Philipp 2015 q2 i? The pattern of n-2 costs across languages is inconsistent between studies, suggesting multiple influences on language activation and possibly multiple loci of inhibition. → Mathieu Declerck & Andrea M. Philipp 2015 (2)

q2 · i? · review · r3

The review describes n-2 language repetition costs measured with three languages: "performance is worse on AB A sequences than on CB A sequences," attributed to persisting inhibition that is stronger two trials after a language was produced. No effect sizes are printed.

"The results typically show that performance is worse on AB A sequences than on CB A sequences. This per- formance difference is explained by assuming that in each trial the non-target languages become inhibited to produce in the target language."

q2 · i? · review · r3

The review reports that across studies (Philipp et al.; Guo et al.; Philipp and Koch) the asymmetry of n-2 costs across languages varied, but "n-2 repetition costs were consistently found," which the authors take to indicate multiple influences on language activation and possibly different loci of inhibition.

"This mixed data pattern does not speak against persisting inhibition as n-2 repetition costs were consistently found"

Discussion¶

Related Claims¶

• Switch costs and mixing costs are common empirical observations across language switching paradigms, except voluntary switching under certain circumstances
• Asymmetrical switch costs are not an unambiguous marker of inhibition: they depend on task type and bilingual profile, and admit non-inhibitory explanations — related
• Language proficiency moderates switch cost asymmetry, but highly proficient bilinguals still show n-2 language repetition costs consistent with inhibition — related
