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 (distortion of measurement resulting from the cognitive behavior or actions of the witnessing observer)
Possible invasion of privacy
Observation of Physical Objects Visible mark of some past event or occurrences.

Measure unconscious eye movements
This device observes and records changes in the diameter of the subject’s pupils.
Psychogalvanometer Measures galvanic skin response Involuntary changes in the electrical resistance of the skin
Assumption: physiological changes accompany emotional reactions
Voice Pitch Analysis
