Second Language Flashcards
Metalinguistics Awareness
Understanding about how language works
four bilingual advantages
Metalinguistic awareness
Creativity
Problem-solving
Multitasking
Adaptive Control Hypothesis
Proposal suggesting that bilinguals’ constant need to monitor and control their languages leads to benefits in nonverbal cognition.
Interference Inhibition
The ability to ignore distracting or misleading information.
Selective Attention
The ability to direct and focus attention on the current task.
Mental Flexibility
The ability to rapidly switch from one cognitive task to another.
Executive Control
The management of cognitive resources to perform tasks efficiently.
Flanker Task
Experimental procedure in which participants respond to the direction of the central arrow in an array regardless of the direction the other arrows are pointing. (Fig 9.8)
Simon Task
Experimental procedure that requires participants to respond to the color of a stimulus regardless of its location.
Dorsolateral Prefrontal Cortex
An area of the brain involved in executive control
two white matter connection networks that are more extensive for bilinguals.
White fiber tracts extending from the frontal lobe to the basal ganglia and back – inhibition of unintended language.
White matter tracts extending from the frontal lobe to the parietal lobe – implicated in switching tasks.
What area of the auditory cortex is larger (more grey matter) in bilinguals
Heschl’s gyrus
Cognitive Reserve
Engaging in stimulating mental or physical activity on a regular basis helps maintain cognitive functioning as we age and protects against dementia.
Should children with autism or SLI be instructed in only one language?
No evidence that bilingualism is detrimental
Family may provide a model of imperfect English
Limitations in the heritage language limit social interactions with family and lead to social isolation
Child may benefit from cognitive “bilingual advantages” in executive control and selective attention
Ultimate Attainment
The endpoint of second language acquisition that typically falls short of full mastery.
