Cards

Term
bidirectional
Definition
(structure<--> function) the reciprocal interaction of structure and function to produce a pattern of development (p.5)
Term
plasticity
Definition
the extent to which behavior or brain functioning can be changed (p.65)
Term
critical/sensitive period
Definition
the time in development (usually early in life) when a certain skill or ability is most easily acquired (p.10)
Term
neuron
Definition
nervous system cell through which electrical and chemical signals are transmitted (p.54)
Term
synapse
Definition
the tiny space between the dendrite of one neuron and the axon of another through which chemical messages are passed (p.54)
Term
proliferation
Definition
the process of nerve-cell division by mitosis (p.56)
Term
migration
Definition
the movement of neurons to their permanent positions in the brain, most of which is completed during the prenatal period (p.56)
Term
differentiation
Definition
the final stage of neuronal development, in which neurons gain in size, produce more dendrites, and extend their axons farther away from the cell body (p.56)
Term
synaptogenesis
Definition
the process of synapse formation (p.57) brain changes in response to new information
Term
selective cell death
Definition
early developmental process in which neurons that are not activated by sensory and motor experience die (p.57)
Term
experience-dependent
Definition
process whereby synapses are formed and maintained as a result of the unique experiences of an individual (p.61)
Term
experience-expectant
Definition
process whereby synapses are formed and maintained when an organism has species-typical experiences; as a result functions (such as vision) will develop for all members of a species-typical environments (p.60)
Term
ontogenetic
Definition
development of the individual over his or her lifetime (p.78)
Term
phylogenetic
Definition
development over evolutionary time (p.78)
Term
sociohistorical
Definition
changes that have occurred in one's culture and the values norms, and technologies such a history has generated (p.78)
Term
ZPD
Definition
Vygotsky's theory, the difference between a child's actual level of ability and the level of ability that she/he can achieve when working under the guidance of an instruction (p.84)
Term
guided participation
Definition
adult-child interaction, the process and system of involvement of individuals with others as they communicate and engage in shared activities (p.86)
Term
scaffolding
Definition
an expert, when instructing a novice, responding to novice's responses in a learning situation, so novice increases his/her understanding of a problem (p.84)
Term
equilibration
Definition
Piaget's theory, the process by which balance is restored to the cognitive structure through assimilation and accommodation
Term
functional invariants
Definition
Piaget's theory, the processes of organization and adaptation that characterize all biological systems and operate throughout the life span (ch.5)
Term
organization
Definition
the idea that every intellectual operation is related to all other acts of intelligence (p.162)
Term
adaption
Definition
Piaget's theory, the process of adjusting one's cognitive structures to meet environmental demands (includes assimilation and accommodation) (p.162)
Term
accommodation
Definition
Piaget's theory, the process of changing a mental structure in incorporate new information (contrast with assimilation)(p.107)
Term
assimilation
Definition
Piaget's theory, the process of incorporating information into already existing cognitive structures (p.162)
Term
object permanence
Definition
the knowledge that objects have an existence in time and space independent of one's one perception or action on those objects (p.137)
Term
continuity vs. discontinuity
Definition
stability of individuals differences in cognitive performance over time vs. instability of individual differences in cognitive performance over time (p.564-565)
Term
dynamic systems
Definition
a set of elements that undergoes change over time as a result of interactions among the elements (p.11) i.g. length of child's leg-disrupt the child-envrionment relationship the child need to reorganize his behavior so parts fit together again
