Study Notes

Psychological Testing and Assessment Overview

Psychological testing measures constructs like IQ, while assessment integrates related data to evaluate clients based on referral questions.

Test Utility Dimensions

Applied vs. Theoretical: Real-world utility vs. validating theories and testing hypotheses.
Describe vs. Predict: Tests can describe current status or predict future behavior, comparing individuals to norm groups.
Max. Performance vs. Typical Performance: Evaluates an individual's best possible effort vs. their routine behavior.

Testing Environments

Conducted in clinical, educational, counseling, and industrial or employment settings.

Categorization of Tests

Construct Measured: Personality or intelligence.
Format: Includes interviews, paper, or computer-based formats.
Reference for Interpretation: Norm-referenced or criterion-referenced interpretations.

Influences on Test Results

Examiner Factors: Prejudice, rapport, and testing knowledge may impact results.
Examinee Factors: Anxiety, motivation, and past experiences can affect performance.

Standardized Testing Procedures

Ensure uniform administration and conditions under which norms are established.

Test Types

Achievement Testing: Evaluates learned information and skills.
Aptitude Test: Predicts future performance based on abilities.

Measurement Concerns

Measurement Error: Difference between measured values and true scores, can occur due to various factors.
Behavior Sampling Limitations: Error reduction through valid and reliable tests and representative norm groups.

Statistical Concepts in Testing

Raw Scores: Original untransformed data.
Standard Scores: Converted raw scores that indicate positional performance within a reference group.
T-Score: Mean of 50 with a standard deviation of ±10.
Z-Score: Indicates how many standard deviations a score is from the mean.

Reliability and Validity

Reliability refers to the consistency of test scores; validity assesses if a test measures what it claims to.
Types of reliability: test-retest, alternate forms, internal consistency, and split-half reliability.
Correlation coefficients illustrate the relationship strength between two variables.

Ethical Considerations

Important training minimizes biases in assessments and ensures informed consent addresses risks, benefits, and purposes.

Historical Milestones in Psychological Testing

Early Testing Evidence: Pythagoras (500 B.C.) practiced physiognomy.
WWI Impact: Increased testing with Yerkes Army Alpha and Beta tests, and Woodworth’s Personal Data Sheet for Army recruits.
Development of IQ Testing: Influenced by Binet, Goddard, and early 20th-century practices.

Measurement Transformations

Benchmark Data: Identifies optimal performance standards.
Percentiles: Represents specific points in data distributions illustrating cases below a certain value.

Conclusion

Understanding psychological testing requires knowledge of test utility, reliability, validity, ethical concerns, historical context, and measurement errors to ensure effective application in real-world situations.
