Document Summary
Psyc 1103 lecture 4 research methods and developmental psych 1. Consider whether bias is playing a role (could be on the part of experimenter or participant) Experimenters may easily miss what they are not looking for. Confirmation bias : experimenter takes any data as confirmation of his/her hypothesis (even if results are ambiguous) Behavior is influenced by expectations about the study (behave how they believe they should ) Demand characteristics : cues that make participant aware of experimenter"s expectations. Social desirability : participants may base their behavior on what they consider socially acceptable. A participant"s expectations or beliefs trigger the expected experimental outcome, even though no manipulation is present. Neither participant nor experimenters know which condition subjects are assigned to. Population : larger group we hope to draw conclusions about. Ex: a small number of college students. All individuals in population have an equal chance of being selected. Representative sample (the next ideal type of sample)
