Unıt 15 Language and Brain

 

Neurolinguistics(sinirbilim),the study of the relationship between language and brain.

 

Parts of the brain:two parts,the left hemisphere and the right hemisphere.

 

Broca’s area:As the anteri- or speech cortex.paul broca,a french surgeon,1860s,damage to this specific part of the brain was related to extreme difficulty in producing speech.

-Dil yeteneği sol yarımkürede yer almalı.

-broca’s area is crucially involved in production os speech

 

Wernicke’s area:The posterior speech cortex.Carl Wernicke,was a German doctor,1870s,damage to this part of the brain speech comprehension difficulties.

-Bu,dil yeteneğinin sol yarımkürede olduğunu konfirme ediyor.

-Wernicke’s area is part of the brain crucially involved in the understanding of speech.

 

The motor complex:which generally controls movement of the muscles(i.e. for moving hands ,feet,arms)[kasların hareketlerini kontrol eder]

*Close to the Broca’s area is the part of the motor cortex that controls the articulatory muscles of the face,jaw,tongue and larynx.

-This area is involved in the actual physical articulation of speech

 

The arcuate fasciculus:A bundle of nevre fibers(sinir telleri yığını)

-a crucial connection between Wernicke’s area and Broca’s area.

 

The localization view(sınırlandırılmış görüş)

-The brain activity involved in hearing a word,understanding it,than saying it,Would follow a defnite pattern.

---The word is heard and comprehended via Wernicke’s area.This signal is then transferred via the arcuate fasciculus to Broca’s area where preparation are made to produce it.A siganl is then sent to the motor cortex to physically articulate the word.

*the localization view is one way of saying that our liguistic ağabeylties have identifiable locations in the  brain.Not support the view Beynin herhangi bir alanına hasar diğer alanlarına da yansır…Linguistic behavior and sites on the wrinkles grey matter

 

Other views:1.Thepathwaymetaphor(process of sending signals through electric circuits.

2.a’steam engine’metaphor [Sigmund Freud](to account certain aspects of the brain’s activity,by talking of the effects of’’reppression’’’’building up pressure’’to the point of sudden ‘’release’’.

3.Aristotle’s metaphor(the brain as a cold sponge)

 

Tongue tips and slips:-the tip-of-the-tongue,phenomenon in which you feel that some word is just eluding (kaçmak) you,that you know the word,but it just wont’t come to the surface.(diliminin ucunda)

Malaphorisms(sözcükleri uygusuzca kullanma)—Speakers produce secant,sextet and sexton when asked to name a particular type of navigational instrument(sextant).

*We need to say a few laughs to break up the monogamy.

a slip-of-the-tongue:tangled expressions such as a long shory stort(for’makea long story short’) and the thine sing (for’the sign thing’) or word reversals,as in use the door to open the key and a fifty-pound dog of bag food----This type of slip is also known as a Spoonerism

(ses veya heceleri konuşurken yanlışlıkla karıştırma)*Noble tons of soil *a shoving leopard to his flock *You have hissed all my mystery lectures*Work is the curse of the drinking classes.

 

-tip of the slung=the result of a sound being carried over from one word to the next

*black bloxes( for’black boxes’)or a sound used in one word in anticipation of its occurance in the next word *noman numeral(for’roman numeral’),a tup of tea(‘cup’)or the most highly payer(‘paid player’)

slips-of-the-ear:Less commonly documented,may provide some clues to how the braintries to make sense of the auditory signal it receives.*great ape *Gladly the cross I’d bear.

 

Aphasia(söz yitimi)

Aphasia is defined as an impairment of language funtion due to localized cerebral(i.e.brain)damage which leads to difficulty in understanding and/or producing linguistic forms.

Broca’s aphesia:serious language disorder(konuşmayla ilgili)-a substantially reduced amount of speech,-distorted articulation and-slow,-often effortful speech.

Agrammatic:lexical morpheme içerir functional morphemeler çıkarılır..Dil bilgisel işaretler kaybolur

*I eggs and eat and drink coffee breakfast.

-In broca’s aphasia,comprehension is typically much better than production.

Wernicke’s aphasia:difficulties in auditory comprehension(sensory aphasia)[duymayla ilgili]

-Someone suffering from this disorder can actually produce very fluent speech which is however,often difficult to make sense of.

*I can’t talk all of the things I do,and part of the part I can go alright ,but I can’t tell from the othere people.

Anomia(doğru kelimeleri bulması zor)is very common and circumlocution(gereksiz kelime kullanma) may be used,as in this answer( to the question’What’s ink for?’):to do with pen.

Conduction aphasia:Much less common.Type of aphasia is identified with damage to the arcuate fasciculus.This disorder typically do not have articulation problems.They are fluent ,but have disrupted rhythm because of pauses and hesitations.Ritim bozulur.

-Konuşma kelimelerini anlamk normalde iyiidirHowever the task of repeating a word or phrase will create major difficulty with forms such as vaysse and fosh as attemted repetitions of the wordsbaseandwash

Şunu belirtmeliyiz ki bu tür belirtiler (i.e word-finding difficulty)tüm aphasia tiplerinde ortaya çıkar.They also occur in Non-aphasic disorders resulting from the brain disease such as dimentia(bunaklık)

-Language disorders of the type we have described are almost always the result of injury to the left hemisphere.

 

Dichotic listening:The language functions must be located in the left hemisphere is called the dichotic listening test.

 

The critical period:

 

Genie

 

           Unit 16 First Language Acquisition

 

Basic requirements:’cultural transmission

-The crucial requirement appears to be the opportunity to interact with others via language.

 

The acquisition Schedule:

 

Some controversies:

 

Caretaker speech:Karakter olarak basitleştirilmiş konuşma biçimini benimsemiş insanlar lüçük çocuklarla iletişim kurmak için baya zaman harcarlar.

 

-Several stages in the acquisition  process have been identified.

 

Pre-language stages:’cooingandbabbling’(3-10 months)

1th stagecooing’(3 months)---velar consonants such as [k] and[g] usually present,as well as high vowels such as [i] and[u].

 

2nd stagebabling’(6 months)---(oturabilir ve birçok sesli ve sessiz harf ürtebilir)contain syllable tyre sounds [mu] [da]

 

3rd stageintonation pattern’(9 months)—to the consonant  and vowel comnination being produced.

(10-11 months)-a standing position)----Using their vocalization

This late stage is characterized by alot of ‘sound-play’andattempted imitation

 

The one-word or holophrastic stage:(12-18 months)- to produce a variety of recognizable single unit utterances.[one-word stage]

Holophrastic: a single form functioning as a phrase or sentence
