It explains the limitations of observation for uncovering internal states like beliefs, motivations, or past behavior. Interviews allow for richer, contextual understanding, while questionnaires are cost-effective and standardized but risk lower response rates. Despite self-report biases, both tools offer valuable insights when designed and administered carefully.As we have seen in the preceding chapter, methods relying on observation are primarily directed toward describing and understanding behavior as it occurs. They are less effective in giving information about a person's perceptions, beliefs, feelings, motivations, anticipations, or future plans; and certainly they provide no information about past behavior or private behaviours, such as sexual activity or dreaming, which are, by their very nature either unfeasible or impossible to observe. To obtain such information, the interview, the questionnaire, and the projective method have been devised These are the topics for this chapter and the next one.enObservationInterviewMotivationsSelf-reportSocial SituationBook chapter
