• Resumen

  • People who were mostly exposed to English with an accent in the early home environment are more native-like when performing various English tasks, compared to those who were mostly exposed to their non-English heritage language (Tao & Taft, 2016). The present study extends from the work of Tao and Taft (2016), further exploring the effects of early home language environment on linguistic and cognitive outcomes later in life. Three groups of young adult participants who differed in their early home language environment were examined on speech comprehension and executive function tasks. Results showed that people who were exposed mostly to non-English heritage languages have disadvantages relative to native monolingual speakers in the comprehension of certain types of stimuli, but show advantages in their executive functioning. Those exposed mostly to nonstandard English showed a less robust advantage in executive functions over native speakers, and showed no apparent disadvantage in speech comprehension.
