A decision before an answer
- A test can give the same wrong classification repeatedly. Consistency alone does not establish validity.
- Your goal: Distinguish major psychological perspectives.
Read the relationship
- Structuralism analysed conscious experience; functionalism asked how mental activity serves adaptation. Behaviourism emphasised observable learning; Gestalt psychology stressed organised perception. These are historical emphases, not interchangeable labels.
- Interpret test reliability and validity.
A test gives consistent scores but measures a different construct. It may have:
Consistency and construct evidence are different.
Use the defining rule
- Psychoanalytic accounts emphasise unconscious conflict, humanistic accounts agency and growth, and cognitive accounts information processing. Compare the explanatory mechanism rather than matching every theory to a single familiar name.
- Use standardisation and base-rate reasoning.
Organised wholes in perception are especially associated with:
Gestalt accounts emphasise the structure of perception.
Check the conditions
- Reliability concerns consistency across measurements. Validity concerns evidence for a proposed interpretation and use. A high reliability coefficient cannot prove that a test measures the intended construct fairly.
- Use standardisation and base-rate reasoning.
In 1,000 people, suppose 10 have a target condition. A screening tool detects 9 of those 10, but falsely flags 99 of the other 990. Among 108 positive screens, only 9/108≈8.3% are true positives. This is a hypothetical methods example, not a diagnostic recommendation.
Consistency of measurement is called ____.
Validity concerns interpretation and use, not consistency alone.
Apply the task format
- Standardisation supplies consistent administration and a relevant reference sample. Norm-referenced standing differs from criterion-referenced mastery. Predictive value depends on base rates as well as sensitivity and specificity.
- Use standardisation and base-rate reasoning.
Do not equate sensitivity with the probability that a positive result is correct, and do not use a classroom score to diagnose a disorder.
Which answer fits this case? · Qual resposta se encaixa neste caso?
Distinguish major psychological perspectives · Distinguir principais perspectivas psicológicas
A norm percentile directly proves criterion mastery.
Relative standing does not show that a mastery standard was reached.
Keep the distinctions
- reliability 信度 — Consistency of measurement under specified conditions.
- validity 效度 — Evidence supporting a particular interpretation and use of scores.
- Distinguish major psychological perspectives.
- Interpret test reliability and validity.
- Use standardisation and base-rate reasoning.
