Observational Methods Direct Observation Without Intervention (Naturalistic) With Intervention Structured Observation Participant Observation Disguised Undisguised Field Experiment Indirect Observation Physical Traces Archival Records

USING OBSERVATIONAL METHODS Two categories of direct observational methods: Observation without Intervention Observation with Intervention Observational methods can also be classified according to the methods for recording behavior. Comprehensive record of behavior Selected behaviors

Observation without Intervention Naturalistic Observation: Observation in natural (“real-world”) settings without an attempt to intervene or change the situation. Goals: Describe behavior as it normally occurs, examine relationships among naturally occurring variables. Naturalistic observation helps to establish the external validity of laboratory findings. Naturalistic observation is used when ethical and moral considerations prevent experimental manipulation.

Observation with Intervention Most psychological research involves observation with intervention. Researchers typically choose from three methods of observation with intervention in natural settings: Participant observation Structured observation Field experiment

Participant Observation Observer is an active participant in the natural setting he or she observes. undisguised: people in the setting know they are being observed disguised: people don’t know they are being observed Disguised participant observation helps control for reactivity, one of the main problems associated with observation.

Participant Observation Reactivity occurs when people change their usual behavior because they know they are being observed. Participant observers may sometimes lose their objectivity by becoming too involved in the situation. Participant observers may influence the behavior of people they are observing.

Structured Observation Researcher sets up (structures) a specific situation in order to observe people’s behavior. Examples: clinical and developmental observations of behavior, psychological testing Structured observation is useful when behavior is difficult to observe as it naturally occurs. Researchers often use confederates to create the structured situation. Problems occur when observers don’t follow the same procedures across observations or observers, and when important variables are not controlled.

Field Experiment Researcher manipulates an independent variable in a natural setting and observes behavior (dependent variable). There must be two or more conditions to compare (independent variable). Researchers often use confederates to create these different conditions. Researchers attempt to have the most control in field experiments.

Recording Behavior Researchers can obtain a comprehensive record of people’s behavior (e.g., video tapes) or select specific behaviors to record. The method for recording behavior determines how the results of the study are eventually measured, summarized, analyzed, and reported. Qualitative Quantitative

Qualitative Records Researchers use narrative records when they want a complete (comprehensive) reproduction of people’s behavior. Examples: videotapes, audiotapes, field notes Narrative records should be made during or soon after behavior is observed. Observers must be carefully trained. Advantage: Can review the record often to observe behavior. Disadvantage: Costly, time-consuming.

Quantitative Records Selected Behaviors: Researchers choose the behavior they want to observe and ignore other behaviors. Researchers need to decide how they will measure the behavior. Examples: frequency of behavior, duration Recording techniques include checklists and electronic recording and tracking.
