Week 3: Bilingual Language Flashcards
Questions on Bilingual Language
Processing/lexicon (2)
Are the lexicons independent or integrated lexicon?
bilingual language processing language “non-selective” or “selective”
current answer: integrated and non-selective
Bilingual Language
Processing: integrated lexicon
support: FMRI
same brain areas are used to represent both languages in bilinguals
language representation in the same area of the brain in both bilinguals and monolinguals
Bilingual Language Processing: non-selective support: van Heuven, et al (1998) English/Dutch words only
English/Dutch bilinguals:
used inter-lingual ‘neighbours’
investing RTs for English lexical decision between bi- and mono-linguals
Results:
more Dutch word neighbours, slower the lexical decision time. only for bilinguals.
Joint activation problem
Bilingual Advantages
have enhanced inhibitory control evident in non-linguistic tasks requiring the inhibition of distracting information.
The controls bilinguals need to be mindful for:
5 main ones.
inhibition and selection(?)
– the intention to speak in a given language
– selection of the word in the intended language
– inhibition of words from the non-target language
– monitoring speech for potential intrusions (other language)
– language disengagement and engagement (switching)
Bilingual Advantages (suggested)
have enhanced inhibitory control evident in non-linguistic tasks requiring the inhibition of distracting information.
More developed (grey area density) in dACC, DLPFC and left ACC
Supervisory Attentional System is…
its components are
language task Schemas operates as a ‘top-down’ inhibitory control mechanism to enable selection of schemas relevant to a goal conceptualiser (C) goal (G) Outcome (O) Inhibited (I)
what is language task Schemas
A language task schema regulates the outputs from the lexico-semantic system by:
1) altering the activation levels of representations within that system
2) inhibiting outputs from the system
language task Schemas remains active till: (4)
(1) its goal is achieved, => inhibits its own activity
(2) it is actively inhibited by another schema
(3) SAS has changed the goal.

Bi Advantages: more grey matter:
what are the areas involved in?
dACC,
- monitoring correct responses during language condition
- switching task
DLPFC:
- guiding response selection under conditions of conflict
- refresh representations in working memory
left ACC:
- detection of conflict

Do bilinguals out-perform monolinguals on non-linguistic measures of cognitive control?
Lehtonen, et al., 2018
(MA across age-grps)
Mixed findings, especially in young ppl Key tasks used: – Flanker task performance – Simon task performance Small effect
