CATEGORIES OF OBSERVATION HUMAN VERSUS MECHANICAL VISIBLE VERSUS HIDDEN DIRECT CONTRIVED

Observation of Human Behavior Benefits Communication with respondent is not necessary Data without distortions due to self-report (e.g.: without social desirability) Bias No need to rely on respondents memory Nonverbal behavior data may be obtained Certain data may be obtained more quickly Environmental conditions may be recorded May be combined with survey to provide supplemental evidence

Observation of Human Behavior Limitations Cognitive phenomena cannot be observed Interpretation of data may be a problem Not all activity can be recorded Only short periods can be observed Observer bias possible Possible invasion of privacy

OBSERVATION OF PHYSICAL OBJECTS Physical-trace evidence Wear and tear of a book indicates how often it has been read
