Bilingual comparative judgments: Evidence against the switch hypothesis

The notion that bilinguals possess a language-switching mechanism was examined. Subjects made comparative judgments about concrete concept pairs (e.g., cow-panther) and abstract concept pairs (e.g., joy-sorrow), which were presented either unilingually or in mixed language. There was no significant difference in latencies for unilingual and mixed language concept pairs, whether the pairs were concrete or abstract. The results substantiate neither the general switch hypothesis nor the notion that between-language and within-language associative networks have different transition probabilities.This research was based in part on the author's master's thesis, submitted to the University of Guelph.
