What is one goal of using psychometrics in psychology?

• A. To make subjective assessments of behavior
• B. To measure cognitive and personality characteristics
• C. To focus solely on emotional responses
• D. To eliminate biases in studies

Answer: (B)

The use of psychometrics in psychology primarily aims to measure cognitive and personality characteristics through the development and application of standardized tests and assessments. These measurements provide quantitative data about an individual's mental capabilities, behaviors, and traits, allowing psychologists to better understand and interpret various psychological phenomena. The design and implementation of reliable and valid psychometric instruments enable researchers and practitioners to evaluate abilities such as intelligence, personality traits, and even mental health status. This systematic approach to measurement is crucial for building theories, conducting research, and applying psychological principles in real-world settings. The other options touch on aspects of psychology but do not accurately capture the core goal of psychometrics. For instance, making subjective assessments of behavior does not align with the objective nature of psychometric tests, which rely on standardized measures. Focusing solely on emotional responses limits the scope of psychometrics, which is more comprehensive and includes cognitive aspects as well. Eliminating biases in studies, while important in research methodology, is not the primary purpose of psychometrics, which is focused on measurement rather than bias reduction.
