We administered German and Spanish versions of the NEO FFI personality inventory to two groups of late bilinguals (second language learners) of these two languages. Regardless of individuals’ first language, both groups scored higher on Extraversion and Neuroticism when Spanish was the test language. In turn, scores on Agreeability were higher when German was used as test language. Results are interpreted as evidence for cultural frame shifts consistent with cultural norms associated with the presently used language. Beyond the acquisition of linguistic skills, learning a second language seems to provide individuals with a new range of perceiving and displaying their own personality.
