Language and Development 1/2 Flashcards
Arbitrary
words have no obvious relation between the sign and its meaning
Systematic mapping
identifying units that make up a word or sentence
Communication system
a shared set of rules or conventions that establish a systematic mapping between words and the world
Recursive rule (and example)
a rule that can be reapplied to the output e.g. The man is chasing the dog [That is chasing the cat]
What are the 3 steps to language comprehension?
- recognise sounds/words
- retrieve meaning of sounds/words
- combine words into a message (by understanding relationships between words)
What are the 3 steps to language production?
- retrieve words from memory
- put words together to form a coherent sentence
- fine-grained motor planning
Aphasia
language impairment as a result of brain damage
Why do some people not possess language?
lose the ability to speak (brain damage)
never fully develop it
can not learn it
What is ‘Plato’s problem’ as explained by Chomsky?
How did he support this theory?
The fact that we know so much must be because some of the knowledge is innate/preexisting
asked a child questions leading him to conclude Pythagoras’ theorem despite knowing he had never learnt about it
Universal grammar
an innate system of combining units within the constraints of structural patterns of any human language
Give 3 issues with nativism
underestimates the impact exposure has on learning, some innate ‘language specific’ knowledge has actually been proven as general perception skills, certain patterns may arise naturally due to all languages trying to solve similar issues in communication, ‘universals’ cannot be that hard wired as some languages do not conform to the universal rules yet children still learn them easily
Give and explain 4 of Hockett’s design features
Semanticity - fixed association between language units and aspects of the world
Discreteness - units are separate and distinct
Displacement - Can talk about what is not actual or present
Productivity - new words and meanings can be created from what is already learnt
Duality of Patterning - meaningless sounds combine to produce meaningful words (e.g. P-A-T, T-A-P)
What are the 4 Ps that determine development?
Profound - changes to one’s outlook on the world
Permanent - not easily reversed, unlike learning
Progressive - usually brings about improvement rather than detrimental change
Pervasive - affect all areas of life
What did Rousseau say about the child?
“The child [is] the father to the man”
What is Haeckel’s maxim?
“ontogeny recapitulates phylogeny”
- the development of the individual replays the development of the species
What are the 5 major debates in developmental psych?
nature vs. nurture, passive vs. active child, reliability of longitudinal stability, individual differences, how to investigate
Nativism
humans are genetically programmed to have a general capacity for language that has evolved as an adaptation
Descartes
innate potential for development
Empiricism
language learning is not genetically programmed but a by-product of cognitive abilities
Locke
emphasis on the environment
child’s mind is a ‘tabula rasa’
Extreme empiricism
Watson
children can be conditioned (e.g. little Albert and the white rat)
What 4 main issues are there in investigating development?
- methodological issues
- children not reliable participants
- early development inherently ‘noisy’ (multiple influences) - the ‘data problem’
- difficult to obtain quantitative measures while maintaining naturalistic context - establishing causal relations
- moving from how the mind develops to the causes of such developments
- difficult often to determine the direction of causation - choosing the right age
- ensuring tasks are age appropriate while assessing the same construct
Can animals learn a human language?
Yes, but lack vocal anatomy to be able to make relevant sounds:
Chimpanzee Vicky learnt 4 words w/speech therapy
Kanzi learnt to understand sentences and knew 100s of words HOWEVER could not use lang productively
Joint attention (what can it predict in infants?)
The focus of two individuals on one object at the same time (can predict vocabulary size up to 2 years later)
How is the language of bees not like that of humans?
it is non-arbitrary
can only communicate about one thing
Give a challenge to the nativist view
Language was actually just a side effect of higher cognitive functioning that gave us an edge over other species
Why do animals not understand pointing?
Do not comprehend the ‘intention to communicate’ - unaware that pointing is done to satisfy their goal rather than the pointer’s won
Why do babies babble?
To practice making sounds relevant to language even if they are not coherent words
Affective pathway
sound production as a result of arousal or emotion that is innate and generally inflexible
Cognitive pathway
controlled, malleable sound production requiring auditory learning and practice
the innate modular view of language
language is an instinct with an innate knowledge of universal language principles
What is the Poverty of Stimulus argument?
Language must be innate as the environment does not provide enough linguistic data for a child to be able to learn every feature of their language
the experience-based interactive view of language
social interaction provides feedback and allows language structures/patterns to be picked up over time
incentive to talk in order to interact
William’s syndrome
a genetic anomaly where language usually remains intact despite other cognitive impairments
Will’s syndrome
delayed language impairment accompanies general cognitive processing delays
Can we invent language?
Yes, feral children left without language will create their own
sign language - if learnt from birth will be just as competent as children that learnt spoken language
