Document Summary
The scientific method: identify a problem/question, formulate a hypothesis, gather data to test the hypothesis. Basic methods of data collection (describing behaviour: self-report methodologies. Structured observations (eg. lab: example video: structured observation (video) General research design (detect relationships: correlational: predict behaviour, experimental: explain behaviour. Correlation design: relationship between two or more variables. Strength: example: reading in the first 2 years and the infant"s vocabulary size. Three types of correlations refer to textbook: positive correlation r > 0 (0 1, no correlation r = 0, negative correlation r < 0 (-1 to 0) Three variables: independent variable: different treatment conditions, dependent variable: what is measured, confounding variables: other relevant variables. Two techniques: random assignment: randomly assign children to the experimental and control groups, experimental control: manipulate or control specific experiences encountered by children. Basic components of an experiment (double check notes from prof) Designs for examining development: quasi-experimental designs.
