Sensation-Seeking Scale Quiz

Sensation-Seeking Scale (SSS)

• The SSS is a 22-item instrument designed to measure individuals' levels of sensation-seeking traits.
• Expect people lining up to bungee jump to score higher on the SSS compared to an age-matched sample shopping at a mall due to their adventurous activity.

Measurement Methods

• Paper-and-pencil measures like the SSS allow for easy administration and can reach a large audience quickly.
• Performance-based measures assess actions in real-time but may require more resources and logistics.

Reference Groups

• Test interpretations can vary significantly depending on the reference group used for comparison.
• For example, evaluating a 22-year-old male exotic dancer's shyness would differ based on whether comparisons are made to other males of his age or to other male exotic dancers.

Quantifying Psychological Traits

• Psychological traits must be well-defined to ensure accurate measurement and quantification.
• Different contexts can provide varied meanings for terms like "aggressive," affecting how traits are assessed.

Test Development

• A test’s construct must be clearly defined, guiding the choice of items that reflect the intended trait.
• Item selection can encompass various aspects, like knowledge of American history or social judgment in the example of adult intelligence testing.

Reliability in Measurements

• Reliability refers to the consistency of a measurement tool, ensuring it provides stable results over time.
• Analogies with scales: a reliable scale that consistently shows an incorrect weight is still reliable, while a scale with erratic readings is neither reliable nor accurate.

Validity and Generalizability

• Validity examines whether a test accurately measures what it claims to. It is critical to understand the intended use of a test for valid applications.
• Generalizability of findings depends on the sample population used during the test's development and how representative it is of the larger population.

Ethical Considerations

• Test administration must adhere to professional guidelines to maintain ethical standards.
• Multiple data sources are necessary to inform decisions, especially in sensitive applications like custody evaluations.

Norms and Standardization

• Normative data are crucial for interpreting test results, affecting how well findings can translate to different populations.
• Differences in local contexts, such as demographic variations between areas (e.g., Los Angeles vs. Dubuque), may limit the applicability of existing norms.

Terminology in Testing

• Normative sample refers to the group from which test norms are derived, while standardization sample is used interchangeably but may also imply a more specific group used for establishing test reliability and validity.
