Scientific Observation Is Systematic “YOU SEE, BUT YOU DO NOT OBSERVE.” Sherlock Holmes
What Can Be Observed? • Physical actions • Verbal behavior • Expressive behavior • Spatial relations and locations • Temporal patterns • Verbal and pictorial records
What Can Be Observed Phenomena Example Human behavior or physical Shoppers movement action pattern in a store Verbal behavior Statements made by airline travelers who wait in line Expressive behavior Facial expressions, tone of voice, and other form of body language
What Can Be Observed Phenomena Example Spatial relations How close visitors at an and locations art museum stand to paintings Temporal patterns How long fast-food customers wait for their order to be served Physical objects What brand name items are stored in consumers’ pantries Verbal and Pictorial Bar codes on product packages Records
Categories of Observation • Human versus mechanical • Visible versus hidden • Direct • Contrived
Observation of Human BehaviorBenefits • 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
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 invasion of privacy
Observation of Physical Objects • Physical-trace evidence • Wear and tear of a book indicates how often it has been read
Scientifically Contrived Observation • The creation of an artificial environment to test a hypothesis
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.
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
Mechanical Observation • Traffic Counters • Web Traffic • Scanners • Peoplemeter • Physiological Measures
Monitoring Web Site Traffic • Hits and page views • Jupiter Media Metrics • Nielsen//NetRatings
Physiological Reactions • Eye tracking • Pupilometer • Psychogalvanometer • Voice pitch
Eye Tracking Monitors • Record how the subject actually reads or views an advertisement • Measure unconscious eye movements
Pupilometer • 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 • Measures emotional reactions through physiological changes in a person’s voice
