Final baby Flashcards
Define theory of mind
our understanding of our own and others mental states and how they influence behaviour
Premack and Woodruff - Chimps w ToM - criticisms
Chimps understanding that humans are seeking a banana, as well as that they know where to look - refuted by Dennet (has to be a disagreement not agreement)
Wimmer and Perner - false belief task and unexpected content tasks - conclusions
FBT - demonstrate an understanding that others may have false beliefs - emerges around 4,5
UCT - 3 yrs can understand they held a false belief
What factors influence False belief reasoning
increased reasoning skills, maturation and our preparedness to learn ab mental states, executive function (ie focus inhibition), Language, pretend play, family conversations ab mental states.
ToM in younger children
- Imitation: at birth
- Gaze following: 2-4 months
- Social referencing: 12 months
- Protodeclarative pointing: 12 months
- intention understanding around 18 months
Wellman et al.
Simple desire psychology vs belief desire psychology
Repacholi and Gopnik
Emergence of belief-desire in children around 14, 18 months
Onishi and Baillargeon
Violation of expectation paradigm, tests implicit false reasoning in 15 month olds (read book)
Developments in the ‘hardware’ system (2)
- Short term memory cap - differences across ages (gr 1, 4 and adulthood increase by .5 digits per)
- Michelin Chi - read text
Developments in the ‘software’ system (2)
1, Mneumonics (memory Strats) rehearsal, organization (semantic) and elaboration
2. Adaptive strategy choice model
Sieger et al. - strategy use alters was we age, learn what works best at the time
3 aspects of the multi store model
- sensory
- short-term store
- working memory - longterm store
- longterm memory
4 active roles humans play in reasoning
1/ Executive function -self reg, planning and executing strats to achieve a goal 2/ Attention -The process of selecting stimuli to focus on 3/ Inhibitory control -Negation of 2 4/ Set shifting - selecting strategies for use
Children as a-strategic
Children use Strats, but w utilization (inability to profit from use) rather than production (inability to spin. impliment)
Most-Effective strategy use across years
3yrs - will open all doors regardless of directives
5yrs - inconsistently apply rules
6/7- consistent but with low performance (ut. def.)
8/9 - apply with high perfv
Transfer utilization plus study
ability to shift Strats when useful, part of executive function
PCCS - dimensional change ard sort
by shape, then by colour (sorting cards)
around 5 yrs develops, prior cant shift
metacognition (define
Knowledge of cog processes and the regulation of activities
Flavell
5-8 yr olds (15% - 75% report having thoughts)
metacog. in preschool
Understand that others think, but view the mind as a passive container (underestimate activity in themselves and others)
metacog. in 8 yr olds
View mind as active and constructive, interesting overlap between meta cog dev and the use of mnemonics
Types of attention
- Sustained - attention in general
- Selective - capacity to focus only on relevant infor
- cog. inhibitory. required
- textbook
Types of memory
event and autobiographical from SP
Examples of preverbal memory
Deferred imitation - 1st instance of event memory?
Infantile amnesia - factors
Sense of self (18-24 mo)
Language - medium for encoding
Social interaction - parental conversational style
elaborative vs repetetive
Children as eyewitnesses
How much do children recall and how suggestible are they?
- Free recall is age dependent, but all info remembered is highly accurate, can access with cues or prompts
- very much so - read textbook
5 major components of language
- Phonology
- phonemes as the basic units of sound - Morphology
- rules for how sounds work - Semantics
- meaning of words - syntax
- rules for meaningful organization of words - Pragmatics
- rules to language use in social context
- aka sociolinguistic knowledge
Brown and Hanlon - contra learning theory
children dont learn how learning theorists assume they do - corrections dont properly function, much more natural
- children are creative in language use
Chomsky’s three proofs, + associated ones
Children acquire language 1. Rapidly 2. Effortlessly 3. Without direct instruction Also... a) devs like maturation b) universal language milestones c) Vast generative ability d) Gram violations follow from applying rules incorrectly (ie, Mooses)
LAD
language acquisition device, innate cog. system that allows children to form utterances and understand the meaning of sentences
- Universal Grammar
Basic underlying structure that characterizes all languages
Sensitive period hypothesis, plus evidence
Humans more proficient at acquiring language before puberty
- Child aphasics recover faster
- language deprived until adolescence = never acquire fully
- Nicaraguan sign language - read more detail
Contra innatism
- LAD concept is rather vague
2. Ignores environmental contributions
Interactionist model
- Native capacity
- desire to share and communicate
- Rich linguistic community
Strategies to foster development
- turn taking
- Interactions around routines
- Child directed speech
- Parental reactions to ungrammatical speech
a) Expansions - responding to gram, corrections
b) Recasts - expansions but not repetetive
c) clarification questions
Developmental periods
- prelinguistic
- holophrastic
- Telegraphic
Prelinguistic features
period prior to age 1 (or b4 first word)
1. sensitive to sentence boundaries
2. Early sounds
- cooing (2 months) - 1 syllable vowel sounds
- babbling (4-6 months) - includes sounds that will be used in speach
- canonical, reduplicated babbling (6mo) - string of identical sounds - similar across cultures
- babbling drift: end of first year, drift to languages they hear, diff sounds used in language, match to intonation to their lang.
Pragmatics: turn taking around 7 - 8 months, due to reciprocal relationships
Holophrastic features
1 word utterances
Holophrase - single word utterances, used to replicated a sentence’s meaning
1st word - 10-15 months
receptive vs productive, word comp around 6-9 months
Problem of Reference
Word learning assumptions and constraints
- Whole object assumption
- Mutual exclusivity constraints (obj have one name)
- doesn’t work across languages - Lexical contrast constraint (inferences ab the meaning of a word made by contrasting the novel word w known ones)
- Syntactical cues - infer semantics by observing used
- 2 yr old will grasp this
- called syntactical bootstrapping - Parental Modelling (children learn words b4 their super or subordinate categories bc thats how they’re used by their family)
- Social Cognitive factors
- Parents label objects kids pay attention to
- Theory of mind - useful asa children understands what parents point to inteltionally
Mapping Errors
- Overextension - Overapplying a subordinate word (poodle = dog)
- underextentions - under applying a super ordinate category (dog = only the family dog)
Naming explosion
Lots of words learned fast, but varies between kids
Telegraphic period
18-24 months, 2 word combinations
telegraphic - only critical words are included
Common words are similar across language
Preschool period (2.5 - 5 yrs)
- Increased complexity - master basic morphology and syntax
- still make types of errors
1. Over regularizations - over generalizing gram rules to instances they dont apply (ex banned)
2. Transformational rules - 2.5-3yrs, children learn to shift declarative statements to questions or otherwise - can be slow to learn, 5 yr old will still make erros
- by 5/6, similar to adult language use
Carol Izard and basic emotions
Adults rate infants emotions universally, so they seem to be implicit at birth ?
Happiness across the years
- Rudimentary smiles to pleasure
- Social Smile at around 6 weeks to care giver interactions
- smile at faces dominantly at 3 months
- 3- 6 months - large smiles when interacting with a care giver
- Lewis, Alessandri and Sullivan - Happiness dem. when in control of outcomes, loss of happiness when loss of control
Anger,
devs around 4-6 months in response to the kid dev intentionality (as kids gain control they become angry when they loose it)
Sadness
in response to pain, sep from caregiver
Fear
Arises in he 2nd half of the first year
stranger anxiety in around 6 months
