Document Summary
Outline: scientific method, data collection methods, basic designs in developmental psychology, methods for studying infants. Identify a problem/question (theoretical and have implications to help teachers/parents: formulate a hypothesis (statement of a predication, gather data to test the hypothesis. Validity (the degree to which a test measures what is intended to measure: data analysis and conclusions. Basic methods of data collection (describing behavior: self-report methodologies. Interviews (structured-everyone will be asked the same question in the same way vs. clinical-direction of interview might be changed depending on the responses) Naturalistic (observers try to remain discreet in the background in the chosen setting, which allows them to see the relevant behavior without it changing) Structured observations (presenting an identical situation to each child and recording the childs behavior) General research design: (detect relationships: correlational: predict behavior (association between two variables, experimental: explain behavior. Correlational design: relationship between two or more variables. Confounding variables: other relevant variables: two techniques:
