Cards

Term
Age Effects
Definition
One of the three fundamental effects examined in developmental research, along with cohort and time-of-measure effects, which reflects the influence of time-dependent processes on development.
Term
Ageism
Definition
The untrue assumption that chronological age is the main determinant of human characteristic and that one age is better than another.
Term
Biological Forces
Definition
One of four basic forces of development that includes all genetic and health related factors.
Term
Biopsychosocial Framework
Definition
Way of organizing the biological, psychological, and sociocultural forces on human development.
Term
Case Study
Definition
An intensive investigation of individual people.
Term
Cohort
Definition
A group of people born at the same point or specific time span in historical time.
Term
Cohort Effects
Definition
One of three basic influences examined in developmental research, along with age and time-of-measurement effects, which reflects differences caused by experiences and circumstances unique to the historical time in which one lives.
Term
Confounding
Definition
Any situation in which one cannot determine which of two or more effects is responsible for the behaviors being observed.
Term
Continuity-Discontinuity Controversy
Definition
The debate over whether a particular developmental phenomenon represents smooth progression over time (CONTINUITY) or a series of abrupt shifts (DISCONTINUITY)
Term
Correlation Study
Definition
An investigation in which the strength of association between variable is examined.
Term
Cross-Sectional Study
Definition
A developmental research design in which people at different ages and cohorts are observed at one time of measurement to obtain information about age differences.
Term
Dependent Variable
Definition
Behaviors or outcomes measured in an experiment.
Term
Experiment
Definition
A study in which participants are randomly assigned to experiment and control groups and in which an independent variable is manipulated to observe its effects on a dependent variable so that cause-and-effect relations can be established.
Term
Gerontology
Definition
the study of aging from maturity through old age.
Term
Independent Variable
Definition
The variable manipulated in an experiment.
Term
Life-Cycle Forces
Definition
One of the four basic forces of development that reflects differences in how the same event or combination of biological, psychological, and sociocultural forces affects people at different points in their lives.
Term
Life-Span Perspective
Definition
A view of the human life span that divides it into two phases:
1. childhood/adolescence
2. young/middle/late adulthood
Term
Longitudinal Study
Definition
A developmental research design that measures one cohort over two or more times of measurement to examine age changes.
Term
Meta-Analysis
Definition
A technique that allows researchers to synthesize that results or many studies to estimate relations between variables.
Term
Microgenetic Study
Definition
A special type to longitudinal design in which participant are tested repeatedly over a span of days or weeks, typically with the aim of observing change directly as it occurs.
Term
Nature-Nurture Controversy
Definition
A debate over the relative influence of genetics and the environment on development.
Term
Nonnormative Influences
Definition
Random events that are important to an individual but do not happen to most people.
Term
Normative Age-Graded Influences
Definition
Experiences caused by biological, psychological, and sociocultural forces that are closely related to a person's age.
Term
Normative History-Graded Influences
Definition
Events experienced by most people in a culture at the same time.
Term
Plasticity
Definition
the belief that capacity is not fixed, but can be learned or improved with practice.
Term
Primary Aging
Definition
the normal, disease free development during adulthood.
Term
Psychological Forces
Definition
One of the four basic forces of development that includes all internal perceptual, cognitive, emotional, and personality factors.
Term
Reliability
Definition
the ability of a measure to produce the same value when used repeatedly to measure the identical phenomenon over time.
Term
Secondary Aging
Definition
Developmental changes that are related to disease, lifestyle, and other environmental changes that are not inevitable.
Term
Self-Reports
Definition
People's answers to questions about a topic of interest.
Term
Sequential Design
Definition
Types of development research designs involving combinations of cross-sectional and longitudinal designs.
Term
Sociocultural Forces
Definition
One of the four basic forces of development that includes interpersonal, societal, cultural, and ethnic factors.
Term
Stability-Change Controversy
Definition
A debate over the degree to which people remain the same over time as opposed to being different.
Term
Systematic Observation
Definition
A type of measurement involving watching people remain the same over time as opposed to being different.
Term
Tertiary Aging
Definition
Rapid Losses occurring shortly before death.
Term
Time-Measurement Effects
Definition
One of the three fundamental effects examined in developmental research, along with age and cohort effects, which result from the time at which that data is collected.
Term
Universal vs. Context Specific Development Controversy
Definition
A debate over whether there is a single pathway of development, or several.
Term
Validity
Definition
The degree to which an instrument measures what it is supposed to measure.
