A Child's World: How We Discover It

Glossary


accommodation  Piaget's term for changes in a cognitive structure to include new information
adaptation  Piaget's term for integration of knowledge into systems
assimilation  Piaget's term for adjustment to new information about the environment
behaviorism  learning theory that emphasizes the predictable role of environment in causing observable behavior.
bioecological theory  Brofenbrenner's approach to understanding processes and contexts of development.
case study  study covering a single case or life.
chronosystem  Bronfenbrenner's term for effects of time on other developmental systems.
classical conditioning  learning based on associating a stimulus that does not ordinarily elicit a particular response with another stimulus that ordinarily does elicit a response.
cognitive neuroscience approach  approach to the study of cognitive development that links brain processes with cognitive ones.
cognitive perspective  view that thought processes are central to development
contextual perspective  view of development that sees the individual as inseparable from the social context.
control group  in an experiment, a group of people similar to the people in the experimental group who do not receive the treatment whose effects are to be measured.
correlational study  research design intended to discover whether a statistical relationship between variables exists.
cross sectional study  study design in which people of different ages are assessed on one occasion
dependent variable  in an experiment, the condition over which the experimenter has direct control
equilibration  Piaget's term for the tendency to seek a stable balance among cognitive elements.
ethnographic study  in-depth study of a culture, which uses a combination of methods including participant observation.
ethnographic study  in-depth study of a culture, which uses a combination of methods including participant observation.
ethological perspective  view of development that focuses on biological and evolutionary bases of behavior.
exosystem  Bronfenbrenner's term for linkages between two or more settings , one of which does not contain the child.
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.
information-processing approach  approach to the study of cognitive development by observing and analyzing the mental processes involved in perceiving and handling information.
laboratory observation  research method in which all participants are observed in the same situation, under controlled conditions.
learning perspective  view of development that holds that changes in behavior result from experience, or adaptation to the environment.
longitudinal study  study design to assess changes in a sample over time
macrosystem  Bronfenbrenner's term for overall cultural patterns.
mechanistic model  model that views development as a passive, predictable response to stimuli.
mesosystem  Bronfenbrenner's terms for linkages of two or more Microsystems.
microgenetic study  study design that allows researchers to directly observe change by repeated testing over a short time.
microsystem  Bronfenbrenner's term for a setting in which a child interacts with others on an everyday, face-to-face basis.
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 reinforcement or punishment.
operational definition  definition stated in terms of operations or procedures used to produce or measure a phenomenon.
organismic model  model that views development as internally initiated by an active organism and as occurring in a sequence of qualitatively different stages.
organization  Piaget's term for integration of knowledge into systems.
participant observation  research method in which the observer lives with the people or participates in the activity being observed.
psychoanalytic perspective  view of development as shaped by unconscious forces
psychosexual development  in Freudian theory, an unvarying sequence of stages of personality development during infancy, childhood, and adolescence. In which gratification shifts from the mouth to the anus and then to the genitals.
psychosocial development  in Erikson's eight-stage theory, the socially and culturally influenced process of development of the ego, or self.
punishment  in operant conditioning, a stimulus that discourages repetition of a behavior
reinforcement  in operant conditioning, a stimulus that encourages repetition of a desired behavior.
sample  group of participants chosen to represent the entire population under study.
scaffolding  temporary support to help a child master a task.
schemes  Piaget's term for organized patterns of behavior used in different situations
scientific method  system of established principles and processes of scientific inquiry.
Sequential study  study design that combines cross-sectional and longitudinal techniques
social learning theory  theory that behaviors are learned by observing and imitating models. Also called social cognitive theory.
sociocultural theory  Vygotsky's term for the difference between what a child can do along and with help.
theory  coherent set of logically related concepts that seeks to organize, explain, and predict data
zone of proximal development (ZPD)  Vygotsky's term for the difference between what a child can do alone and with help.
