Document Summary
Participants quickly ignore observer, natural behaviour starts to emerge. Can see without interrupting or biasing what they"re doing, though. Difficult to control ambient noise level, what server does, etc: artificial- control conditions, variables. Sacrifice realism: professional observers- can have professionals (trained, standardized) but lack in-depth knowledge/deeper understanding of individual. Could have people who know the participant (teachers, friends, family) But they might want to present person in positive light. We can select observers from variety of social situations (work, school, etc. ) to get whole picture of the personality: benefits, limitations. Access to information not attainable through other sources. Even people who know the individual: ex. T-data: different from self-report (questionnaire, ask directly about personality, here, use standardized form of testing. Mri, eeg, pedometer (activity level), rorshach ink blot: rorshach still considered test data because we have standardized set of rules for themes that person is talking about (even though it"s projective technique, limitations.
