Psychological Assessment Notes
Intelligence
- What is Intelligence?
- Francis Galton:
- Intelligent individuals possess superior sensory abilities. Intelligence is composed of distinct processes or abilities, evaluated through separate tests.
- Pioneered research on the heritability of intelligence.
- Alfred Binet:
- Intelligence encompasses reasoning, judgment, memory, and abstraction.
- David Wechsler:
- Intelligence is the collective capacity to act purposefully, think rationally, and effectively interact with the environment.
- It consists of diverse abilities, including non-intellective factors such as drive, persistence, and goal awareness.
- Jean Piaget:
- Intelligence is a biological adaptation that evolves through interaction with the environment.
- Cognitive development arises from this interaction.
Perspectives on Intelligence
- Interactionism:
- Intelligence development is influenced by the interaction between heredity and environment.
- Louis L. Thurstone:
- Intelligence is composed of primary mental abilities:
- Verbal meaning
- Perceptual speed
- Reasoning
- Number facility
- Rote memory
- Word fluency
- Spatial relations.
- Spearman’s Two-Factor Theory:
- Proposes a general intellectual ability factor (g) and specific components (s).
- The g factor is the best predictor of overall intelligence.
- Horn & Cattell:
- Identified two major types of cognitive abilities:
- Crystallized intelligence (Gc): Acquired skills and knowledge dependent on culture and education.
- Fluid intelligence (Gf): Nonverbal, relatively culture-free, independent of specific instruction; often referred to as "street smart".
- Carroll’s Three-Stratum Theory:
- A hierarchical model with:
- g (general intelligence) at the top (3rd stratum)
- Broad abilities (2nd stratum)
- Narrow abilities (1st stratum).
- Cattell-Horn-Carroll (CHC) Model:
- Combines Cattell-Horn Theory with the Three-stratum theory.
- McGrew-Flanagan CHC Model:
- Features 10 broad stratum abilities and over 70 narrow stratum abilities.
- Does not include general intellectual ability due to its limited utility in psychoeducational evaluations.
- E.L. Thorndike:
- Identified three clusters of intelligence:
- Social (dealing with people)
- Concrete (dealing with objects)
- Abstract (dealing with verbal and mathematical symbols).
- Aleksandr Luria (Information-Processing View):
- Focuses on how information is processed:
- Simultaneous processing (integrated at once)
- Successive processing (individually processed in sequence).
- The PASS Model includes Planning, Attention, Simultaneous, and Successive processes.
Measuring Intelligence
- Stanford-Binet Intelligence Scales: Fifth Edition (SB-5):
- Evolved through several revisions (1937, 1960, 1972, Fourth Edition).
- Administered to ages 2 to 85+.
- Yields:
- Full Scale IQ
- Abbreviated Battery IQ
- Verbal IQ
- Nonverbal IQ
- Five Factor Index scores based on CHC theory (Fluid Reasoning, Knowledge, Quantitative Reasoning, Visual-Spatial Reasoning, Working Memory).
- Uses routing tests to direct examinees to optimal difficulty levels, with basal and ceiling levels.
- Scoring: raw scores → standard scores → composite scores.
- IQ categories:
- "Very gifted or highly advanced": 145-160
- "Moderately impaired or delayed": 40-54
- Wechsler Tests:
- Wechsler-Bellevue I (W-B-I): Introduced in 1939, a point scale with verbal and performance subtests.
- Wechsler Adult Intelligence Scale (WAIS):
- First published in 1955.
- Yields Verbal IQ, Performance IQ, and Full Scale IQ.
- WAIS-III (1997):
- Updated with larger materials for older adults, extended floor for intellectual deficits, and expanded norms.
- Yielded a Full Scale IQ and four Index Scores (Verbal Comprehension, Perceptual Organization, Working Memory, Processing Speed).
- WAIS-IV (Current):
- Composed of core and supplemental subtests.
- Introduced new subtests like Visual Puzzles, Figure Weights, and Cancellation.
- Includes General Ability Index (GAI) and Cognitive Proficiency Index (CPI).
- Short Forms of Intelligence Tests:
- Abbreviated versions to reduce administration time, such as the Wechsler Abbreviated Scale of Intelligence (WASI).
- Group Tests of Intelligence:
- Screening tools for larger populations (e.g., Military: Army Alpha/Beta, AGCT; School: California Test of Mental Maturity, Cognitive Abilities Test, OLSAT).
Issues in Assessment
- Culture and Measured Intelligence:
- Cultural background can influence test performance.
- Concepts like "culture-free" and "culture-fair" tests aim to minimize cultural bias.
- Flynn Effect:
- Refers to the progressive rise in intelligence test scores over time.
Personality
- Personality:
- An individual’s unique constellation of psychological traits that is relatively stable over time.
- Personality Assessment:
- Measurement and evaluation of psychological traits, states, values, interests, attitudes, worldview, acculturation, sense of humor, cognitive and behavioral styles, and/or related individual characteristics.
- Personality Traits:
- Various definitions depending on the theorist; Gordon Allport described them as "bona fide mental structures".
Clinical
- Guidance and Counseling:
- Assessment is similar to educational assessment, focusing on career placement and adjustment to normal problems.
- Counseling Psychology:
- Concerned with prevention, diagnosis, and treatment of abnormal behavior, focusing on "everyday" concerns like marriage, family, academics, and career.
- Clinical Psychology:
- Focuses on prevention, diagnosis, and treatment of abnormal behavior.
- Questions in Clinical Assessment:
- Diagnosis of mental disorders.
- Current level of functioning and comparison to peers, including premorbid functioning.
- Treatment selection, which should be tailor-fit to the patient.
- Description of personality, including psychopathological aspects.
- Effectiveness of treatment approaches.
- Diagnosis of Mental Disorders:
- Uses the Diagnostic and Statistical Manual (DSM-5) and the International Classification of Diseases (ICD).
- Biopsychosocial Assessment:
- Explores biological, psychological, social, cultural, and environmental variables contributing to a presenting problem.
- Interview:
- Used for diagnosis, identifying psychotherapy areas, or assessing harm risk.
- Includes therapeutic contracts.
- Types:
- Stress Interview
- Hypnotic Interview (not always practical)
- Cognitive Interview (alternative to hypnotic interview).
- Data Obtained:
- Demographic data
- Reason for referral
- Medical/psychological history
- Current conditions.

- Special Applications of Clinical Assessment:
- Addiction and Substance Abuse: Katatagan Kontra Droga sa Komunidad (KKDK) in the Philippines.
- Forensic Psychological Assessment: Clinical psychology applied in legal contexts (annulment, competency, emotional injury, profiling, custody evaluations, suicide assessment).
- Barnum Effect:
- Personality descriptions from tests fitting patients due to their triviality (e.g., horoscopes).
Industrial
- Assessment in Businesses, Careers, and Industry:
- Measures of Interest: Evaluate testtakers' likes, dislikes, leisure activities, and involvements for vocational assessment and pre-employment counseling. Frequent revision is needed.
- Career Choice:
- Strong Interest Inventory: Assesses interests in recreational pursuits, occupations, school subjects, and activities.
- Self-Directed Search: Explores interests based on Holland's theory of vocational personality types (RIASEC: Realistic, Investigative, Artistic, Social, Enterprising, Conventional).
- Measures of Aptitude and Achievement:
- Achievement Tests: Measure prior learning and crystallized knowledge (e.g., Wechsler Individual Achievement Test).
- Aptitude Tests: Tap more informal learning and fluid intelligence (e.g., IQ tests).
- Measures of Personality:
- MMPI: Overkill, interpreted only by a psychologist.
- MBTI and NEO-PI: Normal tests, usable by lower-level professionals.
- Guilford-Zimmerman Temperament Survey and Edwards Personal Preference Schedule: Measurements tend to relate better to specific variables.
- Integrity Tests: Predict employee theft, honesty, adherence to procedures, or potential for violence.
- Personality and Work Performance: Difficult to establish relationship, used to assess compatibility rather than predict performance.
- Workplace and Personality: High conscientiousness and extraversion correlate with good work performance; high neuroticism with poor work performance.
