Chapter 3:The Neonatal Phase And Infancy Flashcards
What is the neonatal phase
Refers to the period between birth and when the baby is 4 weeks old.
Unappealing physical characteristics
Physical well being assessed with apgar scale for quantitative evaluation of certain critical physical characteristics. Is assesses body colour heartbeat reflex irritability muscle tone and breathing.
Apgar( appearance, pulse,gramice, activity, respiration).
What adjustment to life processes are needed for newborns
Blood circulation: aeration- provision of oxygen on their own
Respiration: obtain O2 themselves and expalsion of CO2. Anoxia: O2 shortage.
Digestion: includes digesting nutrients and excreting waste.
Body temperature: develop fatty layer.
The nervous system: reflexes important for survival.
Immunity: formation of antibodies against infection.
Discuss the perception skills of newborns
Vision: visual acuity- ability to distinguish between closely related elements in visual field. Can recognise faces relatively early on
Hearing: able to distinguish certain sounds.
Smell: can recognise and distinguish smells.
Taste: distinguish strong flavour.
Pain: physiological response eg heart rate and behavioural response are indicative of pain.
Explain sleep and dreaming in newborns
Neonates sleep between 17-20 hours a day.
REM (rapid eye movement) and NREM( non rapid eye movement)
REM associated with dreaming and detected by means off EEG. Neonates spend about half of sleeping time in rem sleep.
Discuss the feeding of neonates
Advantages of breastfeeding:
Antibodies in milk provide Vital protection against various diseases.
Nutrients in mom’s milk stimulate brain growth and myelination of axons.
Breast milk easily digested by the baby.
Breast fed neonates gain less weight and less likely to become overweight.
Sucking mom’s nipple helps avoid malocclusion and prevent tooth decay
How is neonatal learning considered
Classical conditioning
Operant conditioning
Imitation
Discuss what occurs during infancy
Lasts for neonatal phase to about 2nd year of life characterized by rapid growth and development.
Critical stage because foundation for various behavioural patterns is laid during this period.
Dangerous because fatal accident often occurs as baby inability to foresee consequences of behaviour.
Challenging because of increasing drive towards independence.
Discuss the stages of cognitive development based on Jean Piaget Theory
The sensorimotor stage:
Refers to infants who obtain their info through sensory input and motor activity. They gradually develope ability to co ordinate info. This occurs across 6 sub stages which represents a definite advance over previous one.
Cognitive development occurs through circular reaction where infant learn to repeat pleasurable or interesting situations discovered by chance. The repetition becomes a cycle in which cause and effect influence each other.
Substage 1: reflexes Substage 2: primary circular reaction Substage 3: secondary circular reaction Substage 4: coordination of secondary reactions Substage 5: tertiary circular reaction Substage 6: mental representation
Explore the cognitive skills of the sensorimotor stage
Object permanence: refers to the understanding that objects continue to exist when they can’t be seen anymore. Between 8-12 months infants start to grasp this concept. They do undergo the A-not-B error called perseverating search.
Imitation which is the ability to copy someone else’s behaviour. Infant are able to form a mental image of something perceived
Deferred imitation: refers to infants ability to imitate behaviour after they have been exposed to it. Developed from increasing ability to form mental picture of behaviour performed by other person.
Critically evaluate Piaget’s view on cognitive development of infants
Piaget’s sample was too small and not broadly representative.
Methods were to simplistic.
Measurements of brain activity wasn’t available.
Describe the process of information processing for infants
Habituation which occurs when babies are exposed to the same stimulus repeatedly and gradually start showing less interest in it. In babies is determined by introducing stimulus followed by measurements of the infant’s heart rate sucking behaviour eye movement and brain activity.
Dishabituation occurs when a new stimulus appears and they starting paying attention to it.
Visual preference refers to infants tendencies to spend more time looking at one object rather than another
Visual recognition refers to the ability to discrimate between a familiar and unfamiliar object.
Auditory discrimaton refers to ability to differentiate between sounds
Discuss memory in infants
Memory refers to the acquisition storing and retrieving of info which is an important aspect of our daily functioning.
Caterogised in terms of time frame in which memories are retained.
Short term memory: refers to temporary storage of immediate info and includes working memory which is involved in aspects of learning. This memory is limited in storage
Long term memory: refers to the permanent or semi permanent storage of episodic semantic and procedural memory.
Episodic memory refers to memories of events.
Semantic memory refers to memory for facts and general knowledge.
Procedural memory refers to ones memory of how to do things and includes procedures for perceptual motor and cognitive activities
Implicit memory refers to memories of which one isn’t conscious of but influence ones daily functioning.
Explicit memory signifies knowledge acquired through conscious effort.
Infants their recognition and recall memory is tested.
Evaluate language development in infants
Phases of development
Receptive language ( understanding) precedes productive language ( speaking it) this means babies understand language before they are able to speak it.
Explain prelinguistic speech and it’s phases.
Undifferentiated crying (birth-1month) babies use crying as a signal of their needs. Crying is termed undifferentiated because the listener is unable to distinguish whether babies are crying because they are hungry thirsty frightened uncomfortable or in pain.
Differentiated crying (from 2 months) crying distinguishable by parents where babies use various sound patterns and pitches to indicate their different needs.
Cooing and babbling (2months- 5months) cooing refers to squealing gurgling sounds made to express happiness satisfaction or excitement. Babbling refers to simple repetition of sounds
Lallation (7-8 months) means babies repeat sounds and words they have heard.
Echolali (9-10 months) repetition of words or sounds are more correct and deliberate.
Single word sentences(1year) baby begin to speak intelligible words deliberately to communicate with others.
Full sentences: (21months) develop in 5 phases ranging from 2word to sentences increasing in sophisticated language structure.
Babies as young as 9months possess elementary receptive vocabulary. Undergo vocabulary spurt
Comment on the various theories of language development
Learning theory:
+Operant conditioning B.F Skinner gestures and sounds are reinforced. If words associated with strong emotions more likely to be retained.
+Imitation where children learn Language by imitating the speech of adults. Parents act as model but also expand on what child says.
Learning theorist maintain that parents are regarded as expert instructors. Multiple repetition is important. Babies who are linguistically stimulated become well spoken later.
Discuss the social pragmatism
Pragmatism refers to the practical use of something. Social impulses and not explicit learning is involved in the learning of language.
The emotional messages of language and not only the words are important in early language development.
Early conversation between child and parent are important because it indicates that children not only acquire language to solve problems or expressing themselves but to engage in social interaction to. a reciprocal socialisation occurs between parents and children. this pitch variation helps to connect emotions to words.
Conversations include reciprocal activities when actions linked to vocalisations.
Describe the nativist approach
According to nativism every person is born with the ability to acquire language. They acknowledge the role played by learning process but considered innate ability.
Chomsky contribution was the languages acquisition device which is a constellation of interconnecting brain areas present in human species.
Present at birth but dependant on maturation of cells in cerebral cortex which is responsible for fact people can produce and understand infinite number of sentences.
Lenneberg was known for his idea that sensitive or optimal period which a language is acquired easily and more quickly. He sees years before puberty as sensitivity period
