Tolerance of ambiguity, need for cognitive closure and feeling like a different person when speaking different languages

Feeling like a different person when speaking different languages has been investigated before and attributed to several linguistic as well as psychological factors. Language proficiency, the context of language acquisition, personality traits, emotional intelligence, and the topic of conversation as well as the interlocutor have been found to give rise to this feeling. Here, the discussion of this phenomenon is continued and extended to the investigation of the psychological constructs of tolerance of ambiguity (TA) and need for cognitive closure (NCC) as well as several demographic and linguistic variables, including: age, gender, age of second language acquisition (L2 AoA), and second language (L2) proficiency. Data collected via an online questionnaire from a group of 452 bilingual first language (L1) German – L2 English speakers were analysed with binary logistic regression (GLM model).
