dev psych ch. 5-8 Flashcards
auditory cortex
conscious processing of sounds
prefrontal cortex
performs brain’s executive functions- planning, selecting, and coordinating thoughts
amygdala
~neural centers in the limbic system linked to emotion
~a tiny brain structure that registers emotions, particularly fear and anxiety
hippocampus
~a structure in the limbic system linked to memory
~a brain structure that is a central processor of memory, especially memory for location
corpus callosum
axon fibers connecting two central hemispheres
thalamus
relays messages between lower brain centers and cerebral cortex
hypothalamus
~controls maintenance functions such as eating; helps govern endocrine system; linked to emotion and reward
~limbic system; a brain area that responds to the amygdala and the hippocampus to produce hormones that activate other parts of the brain and body
pituitary gland
~master endocrine gland
~limbic system; a gland in the brain that produces hormones when signaled by the hypothalamus
visual cortex
conscious processing of sights
spinal cord
pathway for neural fibers traveling to and from the brain; controls simple reflexes
cerebellum
coordinates voluntary movement and balance
cerebral cortex
ultimate control and information processing center
body changes at 6
weight: 40-50 lbs
height: 3 1/2 ft
adult proportions: legs =1/2 of total height
myelination
the process by which axons become coated with myelin, a fatty substance that speeds the transmission of nerve impulses from neuron to neuron
just right principle
although a sin of pathological obsessive compulsive disorder in adults a normal and widespread phenomenon among young children-routine
lateralization
literally, sidedness referring to the specialization in certain functions by each side of the brain, with one side dominant for each activity; the left side of the brain controls the right side of the body, and vice versa
corpus callosum
a long, thick band of nerve fibers that connects the left and right hemispheres of the brain and allows communication between them
injury control/harm reduction
~practices that are aimed at anticipating, controlling , and preventing dangerous activities; these practices reflect the belief that accidents are not random and that injuries can be made less harmful if proper controls are in place
~primary, secondary, and teritary prevention
child maltreatment
intentional harm to, or avoidable endangerment of, anyone under 18 years of age
theory-theory
the idea that children attempt to explain everything they see and hear by constructing theories
Piaget preoperational thinking: preoperational intelligence
Piaget’s term for cognitive development between the ages of 2&6; it includes language and imagination (which involve symbolic thought), but logical, operational thinking is not yet possible
Piaget preoperational thinking: conservation
the principle that the amount of substance remains the same even when its appearance changes
theory of mind
a person’s theory of what other people might be thinking
Vygotsky social learning: guided partcipation
the process by which people learn from others who guide their experiences and explorations
Vygotsky social learning: scaffolding
temporary support that is tailored to the learner’s needs and abilities and aimed at helping the learner master the next task in a given learning process
fast-mapping
the speedy and sometimes imprecise way in which children learn new words by tentatively placing them in mental categories according to their perceived meaning
overregulationzation
~the application of rules of grammar even when exceptions occur, speaking as if the language is more regular than it actually is
~ex: mouse to mouses instead of mice
teacher-directed programs
stress academics, usually taught by one adult to a group of children
balanced bilingual
a person who is fluent in two languages, not favoring one over the other
Head Start
~when: from 1965 to present
~where: U.S.
~who: federal gov’t and legislation
~what: federally subsidized early education programs for children to get a head start on their formal education
~why: originally intended to lift families out of poverty by promoting literacy; also provides dental care, immunizations, teaching of english, and helping parents teach their children and solve their own conflicts
child-centered/developmental programs
support child development by encouraging children to follow their own interest rather than adult direction
instrumental aggression
~hurtful behavior that is aimed at gaining something (such as a toy a place in line, or a turn on the swing) that some else has
~often increases from age 2 to 6; involves objects more than people; quite normal; more egocentric than antisocial
reactive aggression
~an impulsive retaliation for a hurt (intentional or accidental) that can be verbal or physical
~indicates a lack of emotional regulation, characteristic of 2 year olds; a 5 year old can usually stop and think before reacting
relational aggression
~nonphysical acts, such as insults or social rejection, aimed at harming at social connections between the victim and others
~involves a person attack and thus is directly antisocial; can be veery hurtful; more common as children become socially aware
bullying aggression
~unprovoked, repeated physical or verbal attack, especially on victims who are unlikely to defend themselves
~in both bullies and victims, a sign of poor emotional regulation; adults should intervene before the school years
initiative vs. guilt
Erikson’s third psychosocial crisis, in which children undertake new skills and activities and feel guilty when they do not succeed at them
