Document Summary

Example: considering three possible de nitions for measuring romantic love . I feel light headed when i"m around him/her (yes/no) I cant stop thinking about him/her when were not together (yes/no) I loose track of time when we are together (yes/no) Time spent looking in each others eyes. Here we formulate testable predictions of hypotheses (about our operational de nitions) Hypotheses are usually based on theories (statements which summarize and explain prior research ndings. At this stage we chose the most appropriate research strategy for answering hypothesis. Try to eliminate all unwanted factors that may e ect what we are trying to study. Confounds: threats to interpreting our research ndings. When a researcher fails to control important variables that may in uence the key variables. Some factors that cause confounding: experimenter bias, participant bias (participants may act in ways they believe correspond to what the researcher is looking for)
