Developmental psychology (year one) Flashcards
(255 cards)
What is the stimulus response theory?
- behaviour is a response to stimuli
- only basic reflexes are inherited
What is instrumental conditioning?
- learning through trial and error (reinforcement and reward)
- B.F Skinner
What did Tolleman find?
- when a reward was introduced there was a rapid reduction in rate of errors
- evidence of latent learning (rats formed cognititive map of maze)
What is nativism?
- behaviours cannot be learned but must be the result of innate knowledge
What does Elizabeth Spelke believe?
- humans inherit core knowledge of the world
How does the violation of expectation paradigm work?
- present infants with 2 scenarios (impossible and possible scenario)
- infants look longer at impossible events (have knowledge of the law)
What is the innate concepts theory?
- infants inantely know rules about physical events that allow them to predict events
What is constructivism?
- proposes that the child actively builds a model of the world
According to Piaget, what two mechanisms lead to change in a child?
- assimilation and accomodation
- internal state of child drives development
What is ontogeny?
- development of the individual child
What is phylogeny?
- evolution of species over time
What does shared intentionality involve?
- two agents having a joint goal, which is shared and co-ordinating between eachother
What are newborns equipped with according to Heyes (cognititve gadgets)?
- prosocial temperament (species tolerance)
- attentional biases (to faces, voices, biological motion)
What was the aim of Donellan et al. study?
study intentional communication and responses from caregivers as a predictor of language learned
What was the sample in Donellan et al?
- 58 SES-diverse children
What type of study was Donellan et al?
- Longitudinal study (follow up at 15m,18m,24m)
Describe the method used in Donellan et al?
- Looked at vocalisations/ gestures in 10 mins of home free play with caregiver at 11/12 months
- Children followed up at 15,18 and 24 months to see what words they knew
- CDI used
- Vocalisations, gestures and gesture-vocal combinations used
Consonant + vowel (cv) and non-CV
Index finger point, open hand point
Give, show, conventional (e.g. raising hand to mouth for eating)
What were the two variations also looked at in Donellan et al? Describe the methods
- Infant communicative behaviour : looked at whether the infant looks at caregiver within 1 second of behaviour
- Rate of caregiver response : looked at whether or not caregiver gave a response relating to the infants action within 5 seconds
What were the main findings from Donellan et al?
- Increase in words from CV, show and index- finger point children
o The more CV produced, the greater amount of words at 19 months
o The more non-CV, the fewer amount of words they’ll have at 19 months - Decrease in words from non-CV, open hand point and non-CV/open hand combined
What were the infant communicative behaviour findings in Donellan et al?
- gaze-coordinated vocalisation and show produced the greater change in words at 19 months
Non-gaze co-ordinated actions/vocalisations produce fewer words produced at 19 months
What were the caregiver response findings in Donellan et al?
: gaze co-ordinated and responded-to vocalisations and responded-to-vocalisations produced highest change in words at 19 months
Rate of vocalisation is important predictor of language development
Important that caregiver responds to vocalisations and that child is gaze-coordinated
How many words does a child know by age 6
14,000
Name the three stages of Bate et al. study
Perlocutionary acts (birth-10months) : behaviours not intended as communicative, but does have consequences
Illocutionary acts (10-12 months) : intentionally communicate with unconventional forms e.g. pointing, prelinguistic vocalisations
Locutionary acts (12months+) : intentional communication, using conventional forms
Describe perlocutionary acts
