Study Notes

Types of Psychological Tests

Objective Tests: Require predetermined correct answers; minimal subjective scoring.
Examples: True/False questions (e.g., "Ottawa is the capital of Canada"), memory recall tests (e.g., recall sequence of numbers).
Projective Tests: Respond to ambiguous stimuli; interpretations are subjective.
Examples: Rorschach inkblot test, Thematic Apperception Test (TAT), word association tests.

Dimensions Measured

Achievement Tests: Measure prior learning in specific academic areas; commonly used in education.
Aptitude Tests: Assess potential for learning or ability in new roles (e.g., LSAT, GRE).
Intelligence Tests: Evaluate an individual's broader ability to cope with environments; often utilized for screenings.
Interest Inventories: Gauge interests for educational programs and career choices; not predictive of success.
Personality Tests: Assess character and disposition; used in various settings including clinical and organizational.

Major Subject Categories

Achievement, behavior assessment, developmental, educational, English/language, fine arts, foreign languages, intelligence, mathematics, neuropsychological, personality, reading, science, sensorimotor, social studies, speech/hearing, vocations.

Psychological Tests and Surveys

Surveys: Collect group-level information; results reported at question level with response percentages.

Decision-Making with Test Results

Individual Decisions: Based on test-taker's self-assessment.
Institutional Decisions: Decisions by entities influenced by test scores.
Comparative Decisions: Involve ranking individuals based on test scores.
Absolute Decisions: Determine qualifications based on minimum scores.

Professionals Utilizing Psychological Tests

Educational Settings: Administrators, teachers, school psychologists, and career counselors.
Clinical Settings: Various clinicians and consultants.
Organizational Settings: HR professionals and industrial/organizational psychologists.

Controversies in Psychological Testing

Issues arise concerning the use and interpretation of test results, particularly with intelligence, aptitude, and integrity tests.
Historical bias observed in intelligence testing, especially regarding disadvantaged minority groups.

Intelligence Testing Historical Context

Robert Yerkes: Introduced mental testing during WWI with Army Alpha and Beta tests; raised questions about cultural bias.
Walter Lippmann: Critiqued testing methods; noted discrepancies in scores between ethnic groups.
Gould (1982): Argued against mass intelligence testing due to cultural biases, leading to discontinuation of early tests.

Continued Debate on Intelligence Testing

Noteworthy works: "The Bell Curve" by Herrnstein & Murray; APA report questioning genetic vs. cultural influences on intelligence.

Sources of Test Score Differences

Factors include age, sex, socioeconomic status, education level, and culture.

Cultural Influences on Psychology

Cognitive processes may show cultural distinctiveness; relevant in attention, memory, emotion perception, and more.

Sources of Bias in Psychological Testing

Construct Bias: Incompatibility across cultures in what is measured.
Scales of Measurement: Interval scales used for statistical calculation. Includes Likert-type scales for more nuanced data analysis.

Understanding Levels of Measurement

Ordinal Data: Most psychological tests yield this type; intervals may not be equal.
Interval Scales: Equal distances between points; allow for advanced statistical functions.
Ratio Scales: Have an absolute zero point, enabling ratio comparisons.

Variability Measures in Psychological Testing

Range: Difference between highest and lowest test scores.
Variance: Indicates whether scores cluster around the mean or vary widely.
Standard Deviation (SD): Reflects how much scores deviate from the mean; easier interpretation as it's in the same units as the mean.

Statistical Methods for Test Scores

Z-scores: Show how many standard deviations a score is from the mean; useful for comparing to norms.
T-scores: Offer a similar interpretation as z-scores but use a different scale (mean of 50, SD of 10).
Percentiles and Stanines: Provide contextual understanding of test scores relative to a population.

The Role of Norms

Norms serve as benchmarks for interpreting test scores achieved by specified groups. Norm-based interpretations guide analyses of individual performance against standardized measures.
