Psycholinguistics is the study of the cognitive processes involved in language acquisition and use. Researchers have developed models to describe and predict specific language behaviors in bilinguals. One influential model is Levelt's speaking model, which describes the process of language production from intention to articulation of sounds. Paradis proposed the subset hypothesis based on research with bilingual aphasia patients. Language choice in speaking involves matching chunks from a pre-verbal message to the meaning and language of the appropriate lemma. Experimental studies examine how processing reflects a word, sentence, or text's structure and meaning in comprehension and production.

2. What is
psycholinguistics ?
Psycholinguistics is the study of the cognitive processes
that support the acquisition and use of language.

3. Cognitive Models:
Language Production in Bilinguals

4. Modelling Language
Modelling Language Production of the Competent Bilingual In
psycholinguistics researchers try to develop models to describe and
preferably predict specific language behavior. The aim is to capture
all aspects of language use.

5. Levelt’s speaking
model.
- Aims at describing the process of language production
from the development of communicative intentions to the
articulation of the sounds.

6. On the basis of research on Bilingual aphasia , Paradis
(1981) proposed the sub – set hypothesis

7. Language Choice
In speaking , the step which is probably most crucial is
the matching of chunks from the pre verbal message with
the meaning part of lemmas.

8. Poulisse and Bongaerts
(1994)
argue that language is one of the features used in the selection
process, so for the selection of the lemma boy , not only do the
semantic features male and young have to match relevant
conceptual information in the preverbal message , for bilingual
speaker how has English one of his languages , the lemma boy ,
will need to contain about which language it belongs to

9. Experimental studies
Experimental studies of language Production in L1 and L2 In studies
of comprehension, a word sentence, or text can examine the way in
which processing reflects its structure and meaning .

10. Illustrative researches on second language acquisition and
bilingualism. The non selective nature of lexical access In the lexical
decision task letter strings are presented and the participant must
decide weather they are real words or not.

11. Developing lexical
Developing lexical proficiency in a second language Few studies have
taken a developmental approach to this issue to ask how nature of
activated lexical information changes with increasing proficiency in L2 .
Few have compared and have observed differences consistent with the
view that initially the high degree of activation on L1 influences in L2

12. Forgetting and
relearning
Through non-use of a language, the level of activation of knowledge in
that language decreases even to point that the language is considered
lost for foreign language teaching is how such knowledge can be
reactivated again using our knowledge of the mechanics of language
production and perception. Unfortunately , very little has been done
on this so far.

13. Language
Implications Language production and language perception
two factors determinate accessibility of linguistic elements in
particular non- balanced bilinguals and language learners.
