Scientific Observation Is Systematic “YOU SEE, BUT YOU DO NOT OBSERVE.” Sherlock Holmes
What is Observation Research? • The systematic process of recording the behavioral patterns of people, objects, and occurrences as they are witnessed. • No questioning or communicating with people typically occurs. • “Where observation is concerned, chance favors only the prepared mind.” • Louis Pasteur
Human vs. Mechanical Observation • Human Observation • Human being is the observer. • More flexibility • Observer bias • Mechanical Observation • A device is the observer/recorder. • Traffic cameras • Click-through rates • Security cameras
Visible vs. Hidden Observation • Visible Observation • Observer’s presence known to subject(s). • Reduced chance of privacy violations • Hidden Observation • Subject(s) unaware observation is taking place. • Minimizes respondent error
Direct Observation • Straightforward attempt to observe and record what naturally occurs • The investigator does not create an artificial situation
Contrived Observation • Investigator creates an artificial environment in order to test a hypothesis. • Airline passenger complaining about the peanuts may be a researcher investigating how flight attendants respond to complaints. • Mystery shoppers
Response Latency • Recording the decision time necessary to make a choice between two alternatives • It is presumed to indicate the strength of preference between alternatives.
Observation of Human BehaviorBenefits • Communication with respondent not necessary • No distortions due to self-report (e.g.: no social desirability) bias • No need to rely on respondents’ memory • Nonverbal behavior data may be obtained
Observation of Human BehaviorBenefits • Certain data may be obtained more quickly • Environmental conditions may be recorded • May be combined with survey to provide supplemental evidence
Observation of Human BehaviorLimitations • 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 invasions of privacy
Observation of Physical Objects • Physical-trace evidence • Wear and tear of a book indicates how often it has been read
Content Analysis • 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
Physiological Reactions • Eye tracking • Pupilometer • Psychogalvanometer • Voice pitch
Eye Tracking Monitors • Measure unconscious eye movements • Record how the subject actually reads or views an advertisement
Pupilometer • Device observes and records changes in the diameter of the subject’s pupils.
Psychogalvanometer • Measures galvanic skin response • Involuntary changes in electrical resistance of the skin • Assumption: • physiological changes accompany emotional reactions
Voice Pitch Analysis • Records abnormal frequencies in the voice that (supposedly) reflect emotional reactions to stimuli
Measuring Physiological Reactions Problems • Valid measure of future sales, attitude change, or emotional response? • Measuring device sensitivity • Identifying arousal is one thing • Precisely measuring levels of arousal is another • Measuring device(s)’ expense • Subjects in artificial surroundings • Subjects know they are being observed
