Chapter 8 Observation Studies
Learning Objectives Understand . . . When observation studies are most useful. Distinctions between monitoring. nonbehavioraland behavioral activities Strengths of the observation approach in research design. Weaknesses of the observationapproach in research design.
Learning Objectives Understand . . . Three perspectives from which the observer- participant relationship may be viewed. Various designs of observation studies.
Pull Quote “Today, scores of built-in sensors in Formula One cars continuously capture a multiplicity of variables—including RPMS, weather, road conditions, the angles on a track’s s-bends, wear on tires, to pit stop now or next lap—and process it into data for active simulation models that inform a drivers’ instantaneous decisions. Formula One racing today is as much about deriving Continuous Intelligence and decision-making as it is about engine speed and driving expertise.” John Chen, CEO, Sybase

Selecting an Observation Data Collection Approach: Behavioral
Behavioral Observation “We noticed people scraping the toppings off our pizza crusts. We thought at first there was something wrong, but they said, ‘We love it, we just don’t eat the crust anymore.” • Tom Santor, • Donatos Pizza

Errors Introduced by Observers Halo Effect Observer Drift
Evaluation of Behavioral Observation Strengths • Securing information that is otherwise unavailable • Avoiding participant filtering/ forgetting • Securing environmental context • Optimizing naturalness • Reducing obtrusiveness Weaknesses • Enduring long periods • Incurring higher expenses • Having lower reliability of inferences • Quantifying data • Keeping large records • Being limited on knowledge of cognitive processes
Key Terms • Concealment • Event sampling • Halo effect • Observation • Direct • Extralinguistic • Indirect • Linguistic • Nonverbal • Participant • Simple • Spatial • Systematic
Key Terms • Observation checklist • Observer drift • Physical condition analysis • Physical trace • Process (activity) analysis • Reactivity response • Record analysis • Spatial Relationships • Time sampling • Unobtrusive measures

Research Thought Leader “Once a pattern becomes predictable, the brain starts to ignore it. We get bored; attention is a scare resource, so why waste it on something that’s perfectly predictable.” Jonah Lehrer neuroscientist and author, How We Decide

Snapshot: Wal-Mart Implements RFID Labels “We can certainly understand and appreciate consumer concern about privacy. That’s why we want our customers to know that RFID tags will not contain nor collect any additional data about our customers. In fact in the foreseeable future, there won’t even be any RFID readers on our stores’ main sales floors.” Linda Dillman EVP & Chief Information Officer Wal-Mart
