Chapter 4: Early Childhood Flashcards
Give details regarding the general physical development during early childhood
Height and weight: during 1st 30months 80% increase in height and 300% increase in weight. At 4 children have doubled in birth length. Ave mass increase is about 2kg per year where height is about 5-8cm p.a
Physical proportion: loss of baby fat increase in muscle and bone growth cause loss of chubby appearance and resemble young children
Muscle and bone growth: promoted by daily activities like running and further ossification strengthen bones
Teeth: children lose primary teeth replaced by more permanent teeth
Brain development: at 3 brain reaches 75% of total adult weight and at 5 approx 90%. The frontal lobe areas of cerebral cortex devoted to planning and organising behavior developes. Heightened development in left cerebral hemispheres support expanding Lang skills. Diff connection established among different brain structure enhance balance and motor control alertness and consciousness.
Perceptual development: visual improvement in ability to distinguish detail in environments. Figure ground perception improve between 4-6yrs which is the ability to distinguish between the object which is focused and rest of percetual field
By 3 most can hear soft sounds called auditory acuity.
Motor development: gross motor skills- use of large muscles by 3 children can run and jump well. 4 yr olds can throw and catch objects. At 5 able to ride a bicycle.
Fine motor skills- refer to use of small muscles in hands and fingers.at 3 children still experience problems. 4 most can draw lines and pictures 5 can cut out use utensils. Improved co ordination of muscles and dexterity enables children to play simple instruments draw better and start writing.
Bilateral co ordination- improves and show preference for using one hand from other which by 5 is fixed.
What influence does heredity and hormones play on physical development
Genes influence growth by controlling the body’s production of hormones.
The pituitary gland at the base of brain releases GH necessary for development of body tissues. Thyroid stimulating hormone (TSH) stimulated thyroid gland to release thyroxin necessary for normal development of nerve cells of the brain and GH to have full impact on body size.
What influence does nutrition play on physical development
Malnutrition: accociated with 30-50% of child death. Lowers resistance to infections. Inadequate weight or height gain. Increases risk of delayed motor and mental development, deficits on cognitive ability morbidity and mortality.
Obesity which is extreme amount of total body fat has Physical and mental health risks. These risks include orthopaedic neurological pulmonary gastrointestinal and endocrinic conditions. The psychological consequences are low self esteem lack of confidence and depression. The psychosocial impact is perception of being unattractive and social rejection.
Undernourishment between conception and age of 2 increases risk of impaired cognitive development.
What influence does emotional well being play on physical development
Environmental factors like divorce marital conflict unemployment and poverty can have effects on growth of child.
Condition where children show delayed physical growth dur to stress and emotional deprivation is called psychosocial or deprivation dwarfism where they are below ave height not due to malnutrition. They experience emotional problems due to unstable family environment and lack of emotional care or support.
Hypothesis of this includes
- Stress influence functioning of pituitary gland where GH affected
- Stress influence digestion process and affects secretion of digestive juices
- Effects immune system causing greater susceptibility to viruses.
Discuss Piaget’s theory of the preoperational stage with regards to cognitive development
Operations indicate an action or mental representation carried out through logical thinking.
Preoperational thinking refers to illogical thinking implying that they aren’t yet ready to engage in logical mental operations. This stage lasts from 2-7 and subdivided into symbolic or preconceptual period (2-4) and the intuitive period (4-7)
Symbolic period characterised by increasing complex use of symbols or mental representation like words numbers or pictures to which child attached meaning
During intuitive period children begin to use primative reasoning and want answers to questions. They start developing own ideas about world which are simple.
Explain the advances of preoperational thought
Mental representation includes:
?deferred initiation which refers to ability to repeat behavior of a model that’s not present
? Symbolic play which refers to substituting imaginery situation for real ones.
? Spoken language which is most evident development during preoperational period. Thinking occurs through representation of action and ability to use words and understand their symbolic meanings gives new meaning to their world.
Expand on the immature aspects of preoperational thought
Perceptual centration: refers to tendency to only one attribute of what one observes and to ignore the rest. Unable to explore all aspects of a stimulus and center attention on what to them appears to be more salient. Due to inability to not being able to process multiple characteristics and dimensions tend to make perceptual errors.
Conservation: the understanding that matter can change in appearance without changing in quantity.
Irreversibility: refers to an inability to reverse an operation.
Preoperational thought limits ability to classify and categorise and concept of number. By the end of this stage children can classify and categorise objects on basis of one dimension. They don’t have number concept and lack basic number skills like ordinarity cardinality number transformation and estimation
Evaluate the neo- piagetians Theory of cognitive development
Neo-piagetians are theorists who have expanded on Piaget’s theory. They believe that cognitive development is an action based self regulating constructive process and disagree on the generalised competence. They believe that it should be described for each task and in every context.
Robbie case believe children thinking is influenced by executive processing space which refers to activate temporary conscious memory and to max number on how many schemas may be attending to which refers to operational efficiency. This is improved through practice and brain maturation as child gets older.
Discuss the child as theorist concept
Their naïve theories because they aren’t created by specialists and evaluated by formal research but are valuable as they allow child to understand new experiences and predict future events.
The core knowledge hypothesis suggest that children are born with basic knowledge of the world elaborated based on child experience.
Naive physics: refers to understanding of objects and properties. They know a physical object can’t move through another object. Middle of 1st year are aware that one object bumping another can cause it to move and also that unsupported objects can fall. Tall object can hide short object
Naive biology: distinction between Living and non living objects. By 12_15 m infants determine that animate objects are self propelled and act to achieve goals. Theory includes
Movement Growth Internal parts Inheritance Healing
Naïve psychology and theory of mind
Naive psychology refers to individuals tendency to try and explain why people act as they do.
Theory of mind Specifies set of opinions constructed by a child to explain other people’s ideas beliefs desires and behavior.
Henry Wellman believe ToM occurs by 3 phrases: earliest in 2 yr old aware of desires and communicate them and link desire to behavior.
At 3 they distinguish mental world from physical
At 4 mental states become important in child understanding of own and others actions.
Reciprocal thought where children understand that other people think but don’t understand that other people can think about them.
State the prior development needed for ToM
+Self awareness: recognition of child’s own mental state.
+Capacity for pretence: making believe play where use of imagination is needed.n
+Ability to distinguish between reality and pretence: projection of child feelings on to object. Ability to see others aren’t just extensions of desires is later sophisticated development.
+Understanding emotions:
+Executive functioning:
Comment on Vygotskys sociocultural Theory
•zone of proximal development refers to diff between level of performance a child may achieve when doing so independently and the higher level of performance when working under guidance of others. The more a competent person works with children to help move from where they are to where they can be . This is accomplished by cues modelling explanation questions discussion participation encouragement and control of child attention
Scaffolding refers to temporary assistance provided by one person to a less skilled person when learning new tasks. Giving of help but not more than what’s needed promotes learning
Guided participation occurs in context of play and other activities which refers to participation of an adult in a child’s activity in way that helps to structure the activity and bring understanding of it closer to that of adult.
•language and thought
Piaget suggest cognitive development comes first which makes Lang possible. Vygotsky believe Lang ability reflects every aspect of child though and is a significant instrument in structuring thought and regulating cognitive behaviour
Piaget termed self talk in terms of egocentric speech which plays no role in cognitive development
Vygotsky uses private speech for self talk viewing it as intermediate step toward self regulation of cognitive skills. Private speech becomes inner speech important for cognitive growth and regarded as thought.
•mechanisms of development
Development follows dialectical process of thesis antithesis and synthesis which produces higher level concept of more advanced functioning. These opposing ideas confront intertwine and transform into higher level where conflict and resolution play part in development
Analyze the theory of info processing
Short term memory: also working memory and as children progress through early childhood are increasingly able to hold more material in STM.
Long term memory: regarded as permanent storehouse of info. The generic knowledge which is general knowledge about a subject is referred to as script knowledge.
Memory strategies: consists of deliberate mental activity to improve processing and storing of info which includes rehearsal where children repeat target info and retrieval is the process of accessing info and entering it into consciousness. The development of retrieval strategy consists of ability to search memory intelligently efficiently flexibly systematically and selectively to address problems.
Recognition: refers to type of memory that notices whether a stimulus is identical or similar to one previously expressed.
Recall: involves remembering a stimulus that’s not present and involves representational skills.
Metamemory refers to knowledge of memory skills and appropriate use of strategies and metacognition refers to knowledge about and control of thought processes.
Executive functioning: refers to conscious control of thoughts emotions and actions to accomplish goals or solve problems.
How can children cognitive development be enhanced
Exposure to new and interesting situations. New and interesting situations cause a state of disequilibrium in child that will force them to change their cognitive structures where development takes place
Interaction with other children
Play
Practising of cognitive skills
Transmission of knowledge
Pre primary schools
Enrichment programs
Explain the concept of language development in early childhood
By can produce sentences of 4-5 words an by 3 8 words. Mean Length of Utterance (MLU) to calculate the complexity of children’s language usage (usually the average number of morphemes in a set of utterances and not the number of words).
Discuss the role vocabulary
By the age of three, the child knows and can use approximately 900 to 1 000 words, and by the age of six, most children have a receptive (understanding) and expressive (speaking) vocabulary or lexicon of about 10 000 to 20 000 words. This implies that they learn several new words per day. This rapid expansion of vocabulary may occur through a process called fast mapping, which allows the child to pick up the approximate meaning of a word after hearing it only once or twice. Extended mapping, which involves further exposure and usage of the particular word.
Underextensions refers to the tendency to restrict the usage of a word, such as using the word “juice” only for orange juice and not for other fruit juices.
Overextensions refers to the usage ofa word for a wider variety of objects or referents that is incorrect, such as using the word “dog” for another four-legged animal such as a horse
Explain what is phonology and morphology
Phonology refers to the sounds of language.
Morphology refers to the smallest language unit that has meaning in order to structure a word, such as adding an –s to indicate plural or –ed to indicate past tense and –ing to indicate continuing action.
What is grammar and syntax
grammar (the rules of a language) and syntax (combining words in meaningful phrases and sentences according to grammatical rules)
Discuss the pragmatic use of language
pragmatic language refers to the rules for using language effectively and appropriately in social contexts and according to social conventions. These are all aspects of social speech, which is speech intended to be understood by a listener.
