    Study Notes

    Sources of Personality Data

    • Self-Report Data (S-data): Information a person provides about themselves, often through surveys or interviews. It's the most common method for measuring personality, letting individuals share feelings, emotions, beliefs, and experiences. Formats range from open-ended questions to multiple-choice. Simple questionnaires use descriptive adjectives, while more complex forms ask for numerical ratings of traits. Effective S-data relies on respondent willingness and ability to answer accurately.

    • Limitations of S-data: Inaccuracies arise from dishonesty or lack of self-awareness.

    • Observer-Report Data (O-data): Information from others (teachers, family, friends) about a person. It reveals aspects not obtainable through self-report. Using multiple observers improves reliability and validity.

      • Observer Selection: Professional assessors can provide independent perspectives, while those close to the target individual might capture natural behaviors. However, observers can be biased (e.g., parents emphasizing positive traits).

    • Naturalistic Observation: Observing behavior in everyday situations. Offers realistic contexts but little control over situations or sample size.

    • Artificial Observation: Observing behavior in structured situations (tests, experiments). High control, but potentially artificial behavior.

    • Test-Data (T-data): Participants are placed in standardized testing situations to uncover behavioral differences in response to identical conditions. Situations are designed to elicit specific behaviors related to personality variables. Examples include intelligence tests and personality tests like the MMPI.

      • Limitations of T-data: Participants may try to guess the test's purpose and alter their responses. Experimenters might unintentionally influence behavior.

    • Mechanical Recording Devices: Tools like actometers track physical activity levels. Strengths include bias-free data collection, but limitations apply to traits that are not directly measurable.

    • Physiological Data: Measures arousal, reactivity, and information processing speed. Techniques include monitoring heart rate, blood pressure, brain waves (EEG, fMRI). These are valuable for studying personality but often in artificial laboratory settings. Accuracy depends on participants' understanding of the experiment.

    • Projective Techniques: Ambiguous stimuli (e.g., inkblots, pictures) to uncover unconscious desires and motivations. The assumption is that the person will project their personality onto these stimuli. While potentially insightful, scoring is subjective and validity/reliability are uncertain.

    • Life-Outcome Data (L-data): Information gathered from observable life events (e.g., marriage, owning a gun). This "real-life" data can reveal important aspects of personality.

    Issues in Personality Assessment

    • Multiple Data Sources: Matching findings from different data sources builds confidence in the accuracy of personality measures. Discrepancies might not always signify errors and could reflect varied behavioral samples.

    • Fallibility of Measurement: Consistent findings across multiple methods are most convincing. "Triangulation" (multiple methods) strengthens research.

    • Evaluation of Personality Measures: Assessing reliability and validity is key for evaluating personality measures.

    Reliability

    • Refers to the consistency of a measure under comparable conditions. Estimated through different methods.

      • Test-retest reliability: Consistency over time, commonly used with stable traits.

      • Inter-rater reliability: Consistency between multiple observers.

      • Internal consistency reliability: Consistency across items within a test.

      • Parallel-forms reliability: Consistency between two equivalent versions of a test.

    Validity

    • Measures what it is supposed to measure and verified through research.

      • Face validity: A measure appears to measure what it is intending to measure.

      • Predictive/criterion validity: Relationships between test scores and future behavior (e.g., aptitude tests).

      • Convergent validity: Scores correlate with other tests of the same construct.

      • Discriminant validity: Scores distinguish between constructs that should be different.

      • Construct validity: Connection between test scores and a theoretical trait (e.g., intelligence tests.)

    Generalizability

    • The degree to which a measure's validity remains consistent across different contexts. Subsumes reliability and validity concepts.

    Research Methods in Personality

    • Experimental methods: Determine cause-and-effect relationships through variable manipulation and participant equivalence.

    • Correlational studies: Examine relationships between variables, but don't imply cause-and-effect.

    • Case studies: In-depth investigations of individuals, useful for studying rare phenomena but not generalizable to other individuals.
