Language Flashcards
Language
A symbolic shared system for purposeful communication
* Symbolic: There are units to reference something else
* Shared: It is common among a group of people
* Purposeful: To communicate and translate thoughts
Why is there more than one language ?
Language responds to needs
Complexity of language (morphology) decreases with …
More people speaking the language
- because more people speaking a language means it has to be easy to speak (more inclusive)
Cold climate languages have more words for _____
Snow
Words for snow in Swedish: 25
Words for snow in Scots: 421
Tonal languages (tonal contrasts) are spoken in ______ climates
Warmer
Aphasia
Impaired language function, usually from brain injury to the left hemisphere
Broca’s aphasia (non-fluent)
Expressive aphasia
* Intact language comprehension
* Impaired speed production and articulation
Broca’s aphasia in patient Tan
Could only speak one syllable (Tan)
* Still tried to communicate via hand gestures, tone, inflection : suggests these aspects of language are distinct from speech production
Brain damage that causes Broca’s aphasia
Lesion in the left inferior frontal gyrus : Broca’s area
Traits of Broca’s aphasia
Struggle to produce speech
* Halted speech
* Simple sentences
* Speaks in only nouns and verbs
* Drops words from sentences
* Writing also affected
Range of deficits :
From producing certain words → problems with all forms of language (depends on amount of damage to Broca’s area)
Cause of Wernicke’s aphasia (fluent aphasia)
Posterior superior temporal lobe damage : Wernicke’s area
Traits of Wernicke’s aphasia
Speech is fluent but incomprehensible
* Normal prosody and intonation
* interrupts others and speak rapidly
* words do not make a coherent thought, lacks meaning (word salad)
* Includes paraphasias and neologisms, or invented words, in speech
Verbal paraphasia in Wernicke’s aphasia
Substituting a word with something related
* Shares meaning with intended word
E.g. swapping term brother with sister
Phonemic (literal) paraphasia in Wernicke’s aphasia
Swapping or adding speech sounds (metathesis)
* Shares sounds with intended word
* Calling Crab Salad: Sad Cralad
Neologisms paraphasia in Wernicke’s aphasia
Invented words (that do not convey meaning in aphasia)
* Different from those shared with community like Mansplain
e.g. kiuwerold
Conduction aphasia is due to …
Damage to the arcuate fasciculus ( band of white matter tracts) that causes disconnection between Broca and Wernicke’s areas
Traits of conduction aphasia
- Can read, write, and speak
- Can usually understand spoken messages
- Word-finding difficulty
- Unable to repeat words or sentences (message cannot be sent to production area after perception)
Brain lateralization
Language is often considered left lateralized, but :
Broad aspects ((non-literal language skills) of language are supported by the right hemisphere
* Prosody and pitch to convey intonation
* Mood, attitude, gestural communication
Traits resulting from right-hemisphere lesion
- Problems understanding the emotion of a phrase
- Problems understanding sarcastic speech
Are we pre-equipped with language capabilities according to the nuturist view ?
No. Language is acquired through the same mechanisms as skill learning (behaviorist view)
Are we pre-equipped with language capabilities according to the naturist view ?
Yes. We are born with the innate capacity to learn language
Nuturist or behaviourist view
Language acquisition is skill or associative learning
* Explicit training of language
* Trial and error reinforcement as well as modelling other people shapes language
The innateness hypothesis
Grammar, syntactic structure, is separate from semantic meaning and cognition; and it is innate
Chomsky and Naturist views
Language is innate because :
* Language is not stimulus dependent or determined by reinforcement
* Language is way too complex, can be learned without punishment and acquired rapidly
* We can understand and speak what we have not heard before
