Human versus mechanical
Visible versus hidden
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.
Wear and tear of a book indicates how often it has been read

Obtains data by observing and analyzing the content of advertisements, letters, articles, etc.
Deals with the study of the message itself
Measures the extent of emphasis or omission
Eye Tracking Monitors

tracking system uses micro cameras and complex eye tracking software algorithms to electronically monitor eyelid and pupil activity
Record how the subject actually reads or views an advertisement
Measure unconscious eye movements
This device observes and records changes in the diameter of the subject’s pupils.
Measures galvanic skin response
Involuntary changes in the electrical resistance of the skin
