PSYB01H3 Lecture Notes - Lecture 5: Observational Error, Latent Variable, Internal Validity
Document Summary
What are some limitations of this type of assessment? inconsistent measures of laughs, even when we operationalize what a laugh is: ppl can misperceive the same things, there is lots of ambiguity. Were not measuring everything if everything is so sprastic. Why not use a different type of assessment? (cid:523)why don"t we code laughs in a diff way?) Informant-report: asking someone else about how happy she is. Archival data: go to her therapist & code their notes of how happy the woman appears. Behavioral trace: behavior that you leave behind, but don"t know you left behind, code the music in her car (what kinds of music does she listen to?) Behavioral choice: what does she prefer. (appy vs sad book/song : categorize words into happy/sad. Psychophysiological assessments: might lok at hormones. Neurobiological assessments: might look at brain. Because you are tying to map a number onto a behavior, it becomes complex: coding your assessment/beh into numbers.
