Transcript of Age And Neurological Factors (I Presentation)
By: Lorena Palomares and Jorge Isaac
When is the best age to learn a second language?
Could have first language learners any difficulty to learn their first language?
Is only native like profiency considered to be language acquisition or can near native like profiency also be considered?
1. first and second language acquisition in children (C1-C2), holding age constant. 2. second language acquisition in children and adults (C2-A2), holding second language constant. 3. first language acquisition in children and second
language acquisition in adults (C1-A2).
A1
“Biologically determined period of life when language can be acquired more easily and beyond which time language is increasingly difficult to acquire.”
Lenneberg (1967) proposed the Critical Period Hypothesis
The notion derives from biological evidence which was proposed by Lorenz (1958), using example of the new born goslings.

Before age 2 the brain has not developed enough, and after puberty it is has developed too much, with the loss of “plasticity” and the completion of “lateralization” of the language function.

“Adults are capable of learning to communicate a foreign language”
“Foreign accent can’t be easily to overcome”
“Foreign accent emerge at the age of 11-14”
- When exactly is the Critical Period for a Second Language Learning, or does it really exist?
How long does the Critical Period last?
Does a Critical Period exist for first language acquisition?
How might neurological development affectSecond language success?
Does the maturation of the brain at some stage show the failure of language acquisition ability?
As the brain matures, certain functions are assigned to either the left or right hemisphere
believed that the development of lateralization may be complete around age 5

Formulate and understand the meaning of the words and sentences
Interprests the emotion cognotation of those words.
Such studies seem to suggest that second language learners, particularly adult learners, might benefit from more encouragement of right-brain activity in the classroom context.
TEACHERSTEACHERS
RIGHT BRAIN
Visula spacial orientations.
Hand-on actvities
Art-manipulations
Visual, music
Howard Gardne’s multiple intelligences.
Group projects
Active and noisy classrooms
RIGHT BRAIN
Using lectures and lectures
Give problems to resolve
Research/writing
Read independetly
Quiet classroom
Perfeccionist (afraid to fail)
Production of language, or language outputs
The processing of words that we hear being spoken, or language inputs
Children who acquired a second language after the age of 5 may have a physical advantage in that phonemic control of second language is physically possible yet that mysterious plasticity is still present.
Phonological researches support the notion of a Critical Period
AUTHENTIC (Native speaker)
Do you know anyone who started learning a second language after puberty and who nevertheless has an almost perfect accent?
How did assess if the accent was perfect?
Why do you suppose such a person was able to to be succesful?
The acquisition of the communicative and functional purposes of language is, in most circumstances, far more important than a perfect native accent.

We among all animals possess the gift of tongues because we have a time to speak.
AFFECTIVE CONSIDERATIONS
FACTORS FACTORS
HUMAN BEINGS ARE EMOTIONAL WE ARE ALL INFLUENCE BY EMOTIONS THE AFFECTIVE DOMAIN INCLUDES MANY
FACTORS BEING RELEVANT IN S2L THE ROLE OF EGOCENTRICITY (CHILDREN) BABIES (DONT) CHILDREN DEVELOP(INHIBITIONS) SELF-IDENTITY
CRITICAL AND PHYSICAL,COGNICTIVE AND EMOTIONAL CHANGES
STUDENTS LOOK FOR THE AFFECTIVE EQUILIBRIUM
THAT WAS CALLED THE LANGUAGE EGO CHILD EGO IS DYNAMIC, GROWING AND FLEXIBLE
IT MAKES IT EASILY. ACCORDING TO THE AGE THE CHILDRENS
CHANGE IT BECOMES PROTECTIVE AND DEFENSIVE
THEY ARE AFRAID OF ERRORS. WE HAVE TO DISTINGUISH THE YOUNGER,
OLDER,CHILDREN, PREADOLESCENTCHILDREN OF 9 TO 10 DSISONANCE WITH THE LANGUAGE
ADULTS MANIFEST A NUMBERS OF INHIBITIONS
THE SECOND IDENTITY IT IS FRUITSFUL (SMALL DIFERENCES)
THE ROLE OF ATTITUDES(STEREOTYPES)
PEER PRESSURE (ADULT EXPERIENCES) ADULT TOLERATE LINGUISTIC DIFFERENCES MORE THAN CHILDREN DURING A POSSIBLE SPEECH
AFFECTIVE CONSIDERATIONS
LINGÜÍSTIC CONSIDERATIONS
INTERFERENCE BETWEEN FIRST AND SECOND LANGUAGES
FOR CHILDREN AND ADULTS PROCESS OF THE SLA DIFFERS
CHILDREN LEARN TWO LANGUAGES SIMULTANEOUSLY USING SIMILAR STRATEGIES
BILINGUALS ENGAGE CODE SWITCHING( THE ACT OF INSERTING WORDS, PHRASES OR EVEN LONGER STRETCHESOF ONE LANGUAGE INTO THE OTHER
ESPECIALLLY IN BILINGUAL COMMUNICATION
BY FLEXIBILITY
LINGUSITIC AND AND COGNICTIVE PROCESSES O SL ARE SIMILAR TO F1 L SIMILAR STRATEGIES AND LINGUSISTIC FEATURES ARE PRESENT IN BOTH F1 AND SL
STUDIES SAYS THAT SPANISH -LEARNERS AND ENGLISH- LEARNERS COMMIT THE SAME AMOUNT OF MISTAKES IN COMPARISON
ADULTS SL PROCESSES ARE MORE VULNERABLE TO THE EFFECT OF THE F1 L THEY CONSIDER IT TWO EVENTS
ADULTS LEARNS A FOREIGN L ANGUAGE IN A CLASS THEY ACQUIRED IT FOCALLY OR PERIPHERICALLY OR SYSTEMATICALLY ATTEMPT TO FORMULATE LINGUISTIC RULES IN WHAREVER LINGUISTIC INFORMATIO N IS AVAILABLE.
THEY ADULTS AND CHILDREN MANIFEST THE SAME TYPES OF ERRORS
IN ADULTS FIRST LANGUAGE IS FACILITATING THE SL LEARNING
BILINGUALISM
ORDER OF ACQUISITION
FOR CHILDREN AND ADULTS PROCESS OF THE SLA DIFFERS
CHILDREN LEARNING A SL USE CREATIVE CONSTRUCTION PROCESS AS THEY DO IN FIRST LANGUAGE :
CONCLUSION GIVEN USING ELEVEN MORPHEMES
1 . Present progressive 2. In-on 3. Plural 4. Past irregular 5. Possesive 6. Uncontable copula(am- is – are) 7. Articles (a-the) 8. Past regular (ed) 9. Third-person regular (s) 10. Third-person irregular (s)
Why both children and adults in both langauages F1 and L2 exhibit a common order of acquistion
ORDER LEARNING L2 Perceptual salience (how easy is
to see or hear a given structure) Semantic complexity(how many
meanings are expressedby a particular form)
Morpho-phonological regularity(the degree to which languagesforms are affected by their phonological environment.)
Syntactic category(grammatical characteristics of forms)
Frecuency in the input(the numbers of times a given structure occurs in speech addresed tothe learner)
LINGÜÍSTIC CONSIDERATIONS
ISSUES IN FIRST LANGUAGE ACQUISITION REVISITED
COMPETENCE AND PERFOMANCE
COMPRENHENSION AND PRODUCTION
NATURE OR NUTURE UNIVERSALS
Children have de capacity to acquired L2 a any age
Adults is different they should rule out the authenctic accent.
Children learn second language grammar are indeed constrained by UG
Adults acquired a second language withouth any reference to UG
Second language learners have only partial access to UG.
AGE AND ACQUISITION
SYSTEMATICITY AND VARIABILITY LANGUAGE AND THOUGHT
AGE AND ACQUISITION
IMITATIONChiflaren are good imitators,
centering on meaning not surface features
Adults can fare much better imitating surface structure, by rote mechanims they are explicitly to do so.
Sometimes to center in on a surface distintion is a distrating factor, other times is helful
Adults learn may do well attending conciously to truth value
PRACTICE AND FRECUENCY
The amount of stimuli and the number of times practicing are not highly important in learning. What is the mos important is meaningfulness
It goes with meaning communication
AGE AND ACQUISITION
INPUT Classroom second
language learning , parental input y replaced teacher input. Tachers must do well as deliberated but meaningful in the communication with the students.
That input should foster meaningful communicative use language in appropiated contexs.
DISCOURSEIt becomes more
important to the students because of the disterity in acquiring rules of conversation and perceiving intended meaning
AGE AND ACQUISITION
SOME AGE AND ACQUISITION INSPIRED LANGUAGE TEACHING METHODS
TOTAL PHYSICAL RESPONSE
It is known as TPR
Purpose by James Asher in 1977
This method took into account the physical motion ability to produce learning throught reaching , grabbing moving, looking ansd so forth . He also gave attention to the right brain learning . According to Asher , motor activity is a right brain function that should precede left brain language processing. This method took into account the used of commands to develop students reactions about a prhase pronounce by the teacher to expect the students reaction and actions too.
NATURAL APPROACHNATURAL APPROACH
Stephen and krashen(1982) This searcher purposed that
speech emerges as the students as much relaxed as possible in the classroom and that a great deal of communication and acquisition should take place, as opposed to analysis. The Natural Approach advocated the use of TPR at the beginning level of learning when comprehensive input is essential for triggering the acquisition of language.
The Natural Approach was aimed t the goal of basic interpersonal communication skills that is everyday language situations.
The initial task of the teacher was to provide comprehensible input. The students did not need to say anything during the silent period until they feel to be ready to do so. The teacher was the source to the learners and the creator of the input and the creator of interesting and stimulating variety of classroom activities commands, games, and small- group work
