What is the physical growth of children between ages 2-6?
-grow about 3 inches in height and gain about 4-5 pounds in weight each year (growth spurts)
-growth rate is slower than that of infancy and is accompanied by a reduced appetite between 2-6.
What is the neurological development of children ages 2-6?
-declining growth rate; brain maturation slows
-pruning refining neural networks
-greater development in the prefrontal cortex makes it increasingly possible to inhibit emotional outbursts and understand how to play games
What are the key areas of the brain reflected in behaviour?
-corpus callosum: connects right and left hemispheres (growth spurt from 3-6 = improved coordination of right & left hemispheres tasks)
-cerebellum: controls balance and motor movements
-reticular formation: controls/direct attention
-hippocampus: organizes information into long-term memory
-prefrontal cortex: executive functions (+ ability to regulate cognitions, emotions & behaviours)
-neuroplasticity: brain’s ability to change its structure and function in response to experience or damage
What is the motor development of children ages 2-6?
-increased coordination
-sensory motor coupling: motor movement growth occurs as a result of new perceptual experiences
When does toilet training occur and what are 2 issues?
-toilet training usually in first 2 years of early childhood (24-36m)
-Enuresis: repeated voiding of urine into bed or clothes (involuntary or intentional)
-Encopresis: repeated passage of feces into inappropriate places (involuntary or intentional)
What is the sexual development of children ages 2-6?
-sexuality begins in childhood as a response to physical sensations
-infants begin to explore their bodies and genitals as soon as they have sufficient motor skills (stimulation for comfort not orgasm)
-as kids grow, they are more likely to show their genitals to siblings or peers, and to take off their clothes and touch each other
What are some nutritional concerns?
-children may be reluctant to try new foods/preference for certain foods
-many young children desire consistency and may be upset if there are even slight changes to their daily routines
-kids who grow accustomed to high fat, very sweet and salty flavours may have trouble eating foods that have subtler flavours (i.e., fruits & vegetables)
What is Piaget’s Preoperational Stage?
-children between ages of 2-7 use symbols to represent words, images and ideas (pretend play)
-children also begin to use language in this stage, but they cannot understand adult logic or mentally manipulate information
-he believed pretend play helps kids solidify new schemata they were developing cognitively
What are the 2 substages of Piaget’s Preoperational Stage?
-symbolic function (ages 2-4): representational thought; language and play
-intuitive thought (ages 4-7): characterized by curiosity
What is Egocentrism, according to Piaget?
-tendency of young children not to be able to take the perspective of others, and instead the child thinks that everyone sees, thinks, and feels just as they do.
What is symbolic representational ability?
-preschoolers begin to represent objects with symbols
-language –> thinking in words
-pretend play: exercising symbolic shemes
What is conservation and centration?
-conservation: ability to recognize that moving or rearranging matter does not change the quantity
-centration: focused on only one characteristic of an object to the exclusion of others
What is the conservation of liquid task?
-liquid from a regular cup gets poured into a thinner & longer cup
-children assume taller cup contains more liquid
-unable to conserve liquid equivalence across different shapes of containers (conservation error)
What is Piaget’s theory on conservation?
- centration: focus on the height of the containers rather than the volume of liquid
- reversibility: to understand conservation of volume, they would have to think backwards and reverse the steps in the task
- classification: transductive - making faulty inferences from one specific example to another
Was Piaget’s theory correct?
-underestimated children’s abilities in the Preoperational stage
-overestimated children’s abilities in the concrete operations stage
-development exists on a continuum rather than in isolated stages
What are the Cognitive Theories?
-Piagetian stages: descriptive; outlining what happens
-Information processing: explanatory; outlining why things happen
-Sociocultural view: explanatory; outlining how things happen
*these theories are complementary
What are the different components of the Information Processing Model?
-sensory memory (stores raw sensory input for a bit)
-divided attention (switch focus)
-selective attention (focus on 1 task)
-sustained attention (stay on task for long time)
-short-term/working memory (current conscious mental activity)
-long-term memory (permanent memory)
–declarative/explicit memory (consciously recollect)
*semantic memory (not tied to timeline)
*episodic memory (tied to timeline)
–non-declarative/implicit memory (automated skills, don’t require conscious recollection)
What is the Sociocultural Theory?
-Lev Vygotsky
-emphasized role of environment & social interaction
-cognitive development occurs mainly from absorption of knowledge from context
-cognition is a human activity shared through culture
-zone of proximal development
-scaffolding
-private speech
What is the Zone of proximal development?
-range of potential between child’s observable level of performance and their actual underlying ability
-with help, children can achieve multiple tasks
What is Scaffolding?
-adjust facilitation to child’s level of performance
-guided or active participation
-co-construction of solutions
-transfer of strategies and information
What is Private Speech?
-Vygotsky believed that children talk to themselves in order to solve problems or clarify thoughts.
What are the components of Theory of Mind?
-diverse desires: understanding that two people may have different desires regarding the same object.
-diverse beliefs: understanding that two people may hold different beliefs about an object.
-knowledge access: understanding that people may or may not have access to information.
-hidden emotion: understanding that people may not always express their true emotions.
-false-belief: understanding that someone might hold a belief based on false information.
What is the False-Belief Task?
-child sees Sally put ball in basket; then Sally leaves the room
-another person takes the ball out of the basket, puts it in a box, and closes the box so that the ball is not visible
-when Sally returns, the child is asked: Where is Sally going to look for her ball?
-aim: separate what the child knows is true from what Sally thinks to be true
-child must assume Sally’s perspective to correctly answer the question
-Piaget –> egocentrism/self-centrism
-not usually achieved until age 4-5
What are the aspects of Language development?
-fast-mapping: words easily learned by making connections between new words & previous concepts.
-children can repeat words/phrases after hearing them once, but do not always understand meaning.
-overregularization: children learn rules of grammar as they learn language but may apply these rules inappropriately at first.
