Assessing the Evidence for Asymmetrical Switch Costs and Reversed Language Dominance Effects - A Meta-Analysis.

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Neuroscience

Background:

• Language control research faces controversy regarding asymmetrical language switch costs and the reversed language dominance effect.
• Asymmetrical switch costs relate to reactive inhibitory control, while reversed dominance effects indicate proactive control.

Purpose of the Study:

• To empirically evaluate the evidence for asymmetrical language switch costs and the reversed language dominance effect.
• To determine the generality and robustness of these language control phenomena.

Main Methods:

• A Bayesian linear mixed effects modeling approach was employed for the meta-analysis.
• Investigated potential moderating effects of language proficiency and preparation time.

Main Results:

• Overall, the meta-analysis revealed limited evidence for the robustness and generality of both asymmetrical switch costs and the reversed language dominance effect.
• These effects were not consistently observed, even when considering moderating variables like proficiency and preparation time.

Conclusions:

• Asymmetrical switch costs and reversed language dominance effects are theoretically relevant but practically limited for testing language control theories due to their lack of robustness.
• Further research is needed to identify reliable moderating variables and confirm the utility of these phenomena in understanding language control.
