Document Summary
Advantage os a more complete analysis of the individual. Both can be die to a 3rd variable. Example: over weight kid prefers to watch tv, or tv makes the individual overweight. Are differences in one variable at time 1 related to differences in another variable at time 2. Since x precedes y, unlikely that x caused by y. Con control for obvious ones, many other may still play a role. When interpreting correlational studies, important to check what researchers controlled for. Manipulate independent variable: 2 or more groups. People act in a way that we expect them too, so it is best to have them know what you are conducting the research specifically on. Limited generalizability, cant always draw conclusions in which all the pop behaves in that way. Hard-wired physical response to threat activates 2 major systems. It provides commands through network of specialized nerve cells (aka neurons).
