Chapter 1 Flashcards
An introduction to child development (33 cards)
Meta-analysis
A method for combining the results from independent studies to reach conclusions based on all of them
Prefrontal cortex
Cortical region associated with planning, reasoning, problem solving, and other high-level mental functions
Amygdala
An area of the brain that is involved in emotional reactions
Nature
Our biological endowment; the genes we receive from our parents
Nurture
The environments, both physical and social, that influence our development
Genome
Each person’s complete set of hereditary information
Epigenetics
The study of stable changes in gene expression that are mediated by the environment
Methylation
A biochemical process that influences behavior by suppressing gene activity and expression
Continuous development
The idea that changes with age occur gradually, in small increments, like that of a pine tree growing taller and taller
Discontinuous development
The idea that changes with age include occasional large shifts, like the transition from caterpillar to cocoon to butterfly
Stage theories
Approaches proposing that development involves a series of large, discontinuous, age-related phases
Cognitive development
The development of thinking and reasoning
Neurotransmitters
Chemicals involved in communication among brain cells
Sociocultural context
The physical, social, cultural, political, economic, and historical circumstances that make up any child’s environment
Socioeconomic status (SES)
A measure of social class based on income and education
Cumulative risk
The accumulation of disadvantages over years of development
Scientific method
An approach to testing beliefs that involves choosing a question, formulating a hypothesis, testing the hypothesis, and drawing a conclusion
Hypotheses
Testable predictions of the presence or absence of phenomena or relations
Reliability
The degree to which independent measurements of a given behavior are consistent
Interrater reliability
The amount of agreement in the observations of different raters who witness the same behavior
Test-retest reliability
The degree of similarity of a participant’s performance on two or more occasions
Validity
The degree to which a test measures what it is intended to measure
Internal validity
The degree to which effects observed within experiments can be attributed to the factor that the researcher is testing
External validity
The degree to which results can be generalized beyond the particulars of the research
