Chapter 2: Theory and Research Flashcards
accomodation
Piaget’s term for changes in a cognitive structure to include new information
adaption
Piaget’s term for adjustment to new information about the environment, achieved
through processes of assimilation and accommodation
assimilation
Piaget’s term for incorporation of new information into an existing cognitive structure
behaviorism
learning theory that emphasizes the predictable role of environment in causing observable behavior
bioecological theory
Bronfenbrenner’s approach to understanding processes and contexts of human development that identifies five levels of environmental influence
case study
study of a single subject, such as an individual or family
classical conditioning
learning based on associating a stimulus that does not ordinarily elicit a response with another stimulus that does elicit the response
cognitive neuroscience
study of links between neural processes and cognitive abilities
cognitive perspective
view that thought processes are central to development
cognitive stage theory
Piaget’s theory that children’s cognitive development advances in a series of four stages involving qualitatively distinct types of mental operations
contextual perspective
view of human development that sees the individual as inseparable from the social context
control group
in an experiment, a group of people, similar to those in the experimental group, who do not receive the treatment under study
correlational study
research design intended to discover whether a statistical relationship between variables exists
cross-sectional study
study designed to assess age-related differences, in which people of different ages are assessed on one occasion
dependent variable
in an experiment, the condition that may or may not change as a result of changes in the independent variable
equilibration
Piaget’s term for the tendency to seek a stable balance among cognitive elements; achieved through a balance between assimilation and accommodation
ethnographic study
in-depth study of a culture, which uses a combination of methods including participant observation
ethology
study of distinctive adaptive behaviors of species of animals that have evolved to increase survival of the species
evolutionary psychology
application of Darwinian principles of natural selection and survival of the fittest to individual behavior
evolutionary/sociobiological perspective
view of human development that focuses on
evolutionary and biological bases of behavior
experiment
rigorously controlled, replicable procedure in which the researcher manipulates variables to assess the effect of one on the other
experimental group
in an experiment, the group receiving the treatment under study
hypotheses
possible explanations for phenomena, used to predict the outcome of research
independent variable
in an experiment, the condition over which the experimenter has direct control
laboratory observation
research method in which all participants are observed under the same controlled conditions
learning perspective
view of human development that holds that changes in behavior result from experience or from adaptation to the environment
longitudinal study
study designed to assess age changes in a sample over time
mechanistic model
model that views human development as a series of predictable responses to stimuli
naturalistic observation
research method in which behavior is studied in natural settings without intervention or manipulation
observational learning
learning through watching the behavior of others
operant conditioning
- learning based on association of behavior with its consequences
- learning based on reinforcement or punishment
operational definition
definition stated solely in terms of the operations or procedures used to produce or measure a phenomenon
organismic model
model that views human development as internally initiated by an active organism and as occurring in a sequence of qualitatively different stages
organization
- Piaget’s term for the creation of categories or systems of knowledge
- Mnemonic strategy of categorizing material to be remembered
participant observation
research method in which the observer lives with the people or participates in the activity being observed
psychoanalytic perspective
view of human development as shaped by unconscious forces that motivate human behavior
psychosexual development
in Freudian theory, an unvarying sequence of stages of childhood personality development in which gratification shifts from the mouth to the anus and then to the genitals
psychosocial development
- Pattern of change in emotions, personality, and social relationships
- In Erikson’s eight-stage theory, the socially and culturally influenced process of development of the ego, or self
punishment
the process by which a behavior is weakened, decreasing the likelihood of repetition
qualitative change
discontinuous changes in kind, structure, or organization
qualitative research
research that focuses on nonnumerical data, such as subjective experiences, feelings, or beliefs
quantitative change
changes in number or amount, such as in height, weight, size of vocabulary, or frequency of communication
quantitative research
research that focuses on nonnumerical data, such as subjective experiences, feelings, or beliefs
random assignment
assignment of participants in an experiment to groups in such a way that each person has an equal chance of being placed in any group
random selection
election of a sample in such a way that each person in a population has an equal and independent chance of being chosen
