Which concept refers to stability of scores over time?

• A. Reliability
• B. High road emotions
• C. Low road emotions
• D. Validity

Answer: (A)

Stability of scores over time is about reliability. Reliability means a measure yields consistent results under the same conditions, so if you test someone now and later, the scores should be similar if what’s being measured hasn’t changed. This includes the idea of test-retest reliability, which specifically looks at how stable a measurement is across time. Validity, by contrast, is about whether the test actually measures what it’s intended to measure, not how consistent the scores are across occasions. The terms about neural processing routes—high road and low road emotions—refer to separate concepts in neuroscience and aren’t about measurement stability. So the best answer is reliability.
