Chapter 4: Approaches to Psychological Measurement  Observational Methods – research involving the direct observation of behavior o Three decisions to make:  Will the observation occur in a natural or contrived setting?  Will the participants know they are being observed?  How will the participant’s behavior be recorded?  Naturalist vs. Contrived Settings o Naturalistic observation – observation of ongoing behavior as it occurs naturally with no intrusion or intervention by the researcher o Researches observe people or animals in their natural environment and record their behavior o Participation observation – one type of naturalistic observation; researcher engages in the same activities as the people he or she is observing o Contrived observation – behavior is observed in settings that are arranged specifically for observing and recording behavior o Most contrived observations take place in the laboratory; however, some researches set up situations outside of the laboratory to observe people’s reactions  Disguised vs. Nondisguised Observation o Should participant know that they are being observed? o Problem with undisguised observation:  Reactivity – participants act differently because they know they are being watched o Problems with disguised observation:  May violate right of informed consent  Potential violation of privacy  Ways to minimize reactivity o Potential concealment – participants know that they are being observed but not the specific aspects of behavior being observed o Knowledge informants – people who know the participants well, observe and rate their behavior o Unobtrusive measures – indirect measures that can be taken without participants knowing they are being studied  Behavioral Recording o Narrative records – full description of a participant’s behavior o Checklists – researcher records whether particular behaviors or attributes were observed o Measures of Latency  Reaction time – the time that elapses between the presentation of a stimulus and the participant’s response  Task completion time – the length of time is takes participants to solve a problem or complete a task  Interbehavior latency – the time that elapses between two behaviors  duration – how long a particular behavior lasts o Observational rating scales – researcher rates the quality of intensity of a certain behavior  Increasing the Reliability of Observational Methods o Researchers must have clear and precise operational definitions for all behaviors that will be observed and recorder o Raters should practice using the coding system by comparing and discussing their practice ratings  Physiological and Neuroscience Approaches o Neuroscience – a broad, interdisciplinary field that studies biochemical, anatomical, physiological, genetic, and developmental processes involving the nervous system o Cognitive, affective, and behavioral neuroscientists focus on the relationship between physiological processes and psychological phenomena o Five types of psychophysiological and neuroscientific measures  Measures of neural electrical activity  Neuroimaging  Measures of autonomic nervous system activity  Blood and saliva assays  Precise measurement of overt reactions  Self-Report Approaches o Questionnaire - participants respond by writing answers o Interviews – participants respond orally to an interviewer o The questions and statements in self-report measures are called items o Single item measure – item intended to me measured and analyzed by itself o Multi-item scale – set of items that are used together to assess the same construct  Writing good items o Be specific and precise in phrasing items o Write the items as simply as possible, avoiding difficult words, unnecessary jargon o Conditional information should proceed the key idea of the item o Do not use double-barreled items o Choose an appropriate response format o Present the items  Experience Sampling Methods o ESM – participants report on what they are thinking and feeling right now o Diary method – an esm method in which participants keep a daily record of information pertinent to the study o Computerized experience sampling – participants carry small units that are programmed to ask them questions throughout the day  Interviews o Interview schedule – the series of questions that is used in an interview  How to make effective:  Biases in Self-Reports o Social desirability response bias – the tendency to answer question in a socially acceptable way o Acquiescence response style – the tendency to agree with statements, regardless of their content o Nay-saying response style – the tendency to disagree with statements, regardless of the content  Archival Data – analyze data pulled from existing records such as census data, court records, personal letters, old newspapers o Useful for studying:  Social and psychological phenomena of the past  Social and behavioral changes over time  Topics that involve articles, advertisements, or speeches  Anything that must be studied after it occurred
