Study Guide Overview
This study guide covers theories of intelligence (g factor, multiple intelligences, triarchic theory, CHC theory), measuring intelligence (IQ tests, psychometric principles like standardization, validity, and reliability), systemic issues in intelligence testing (Flynn effect, group differences, misuse of scores), and the difference between academic achievement and intelligence (achievement vs. aptitude tests, fixed vs. growth mindset). It also includes practice questions and exam tips.
#AP Psychology: Intelligence - Your Night-Before-the-Exam Guide 🧠
Hey there! Let's make sure you're feeling super confident about intelligence for tomorrow's AP Psych exam. We're going to break it down, connect the dots, and get you ready to rock! This guide is designed to be your ultimate review tool, focusing on what's most important and helping you remember it all.
#1. What is Intelligence?
#1.1 Historical vs. Modern Perspectives
- Early Challenges: Defining and measuring intelligence has always been tricky, leading to some biased approaches. Think about it – what is intelligence, really? 🤔
- The Big Debate: Is intelligence one thing (a general ability) or many different things (multiple abilities)? This is a core question in psychology.
- Key Players:
- Charles Spearman: Proposed the g factor, a single general intelligence that influences all cognitive tasks.
- Howard Gardner: Argued for multiple intelligences, like linguistic, logical-mathematical, spatial, etc.
#1.2 General Ability vs. Multiple Abilities
- g Factor Theory: A single, overarching intelligence affects performance across all cognitive tasks. Think of it as a central processing unit in a computer.
- Multiple Intelligences Theory: Individuals have different strengths and weaknesses across various areas (verbal, mathematical, musical). It’s like having a diverse skill set.
- Robert Sternberg's Triarchic Theory: Three types of intelligence:
- Analytical: Problem-solving skills.
- Creative: Novel thinking and innovation.
- Practical: Applying knowledge to real-world situations.
- Cattell-Horn-Carroll (CHC) Theory: A hierarchical model with broad abilities (fluid reasoning, crystallized knowledge) and narrow abilities (memory, processing speed).
Memory Aid: Think of "G-MAC" to remember the main theories: General (Spearman), Multiple (Gardner), Analytical/Creative/Practical (Sternberg), CHC (Cattell-Horn-Carroll).
#2. Measuring Intelligence
#2.1 Evolution of IQ Tests
- Early IQ Tests: The Stanford-Binet test used to calculate IQ by dividing mental age by chronological age. This is no longer used.
- Modern IQ Tests: Wechsler scales compare your performance to age-based norms. No more mental age calculations!
- Purpose of IQ Tests: Often used in education to identify students who might need extra support or who are gifted.
#2.2 Psychometric Principles in Assessment
- Standardization: Ensures consistent test administration and scoring. Everyone takes the test the same way.
- Validity: Does the test measure what it's supposed to measure?
- Construct Validity: Does it capture the intended concept?
- Predictive Validity: Does it predict future outcomes?
- Reliability: Are the results consistent over time (test-retest) and across different parts of the test (split-half)?
- Norms: Standardized scores that allow for comparisons between individuals and groups.
#2.3 Socio-Culturally Responsive Assessments
- Cultural Bias: IQ tests have been criticized for cultural bias, which can affect scores.
- Stereotype Threat: The fear of confirming negative stereotypes can hurt performance.
- Stereotype Lift: Performance boost from positive stereotypes. This can unfairly advantage certain groups.
- Culturally Responsive Assessments: Aim to reduce bias by considering language, content, and norms relevant to the test-taker's background.
Memory Aid: Remember "SVRN" for psychometric principles: Standardization, Validity, Reliability, Norms.
#3. Systemic Issues in Intelligence Testing
#3.1 Flynn Effect and Societal Factors
- Flynn Effect: IQ scores have been increasing over time. 📈
- Causes: Improved education, better nutrition, more stimulating environments, and higher socioeconomic status.
#3.2 Group Differences in IQ Scores
- Within-Group Variation: IQ scores vary more within groups than between them. Individual differences are key!
- Misinterpretations: Personal and sociocultural biases can lead to misinterpretations of group differences.
- Impact of Inequality: Factors like poverty, discrimination, and educational inequalities can negatively impact IQ scores.
#3.3 Misuse of Intelligence Scores
- Historical Misuse: IQ scores have been used to justify discriminatory practices and limit opportunities. 🚫
- High-Stakes Decisions: Using IQ scores for high-stakes decisions is controversial due to the tests' limitations and potential for bias.
Memory Aid: Think of "FIM" for systemic issues: Flynn effect, IQ group differences, Misuse of scores.
#4. Academic Achievement vs. Intelligence
#4.1 Achievement and Aptitude Tests
- Achievement Tests: Measure what you've already learned (reading, math).
- Aptitude Tests: Predict future performance (SAT, LSAT).
- Distinction: While related to intelligence, achievement and aptitude are influenced by motivation, opportunity, and test-taking skills.
#4.2 Fixed vs. Growth Mindset
- Fixed Mindset: Intelligence is seen as an innate, unchangeable trait. 🚫
- Growth Mindset: Intelligence can be developed through effort and learning. 💡
- Impact: Promoting a growth mindset leads to increased motivation and better academic outcomes.
Memory Aid: "Aptitude is about future, Achievement is about past"
#Final Exam Focus
- Highest Priority Topics: Theories of intelligence (g factor, multiple intelligences), psychometric principles (validity, reliability), cultural bias, stereotype threat, growth mindset.
- Common Question Types:
- MCQs: Identifying the correct theory or concept, applying psychometric principles, understanding cultural bias.
- FRQs: Analyzing the impact of societal factors on intelligence, discussing the ethical implications of intelligence testing, comparing and contrasting different theories of intelligence.
- Last-Minute Tips:
- Time Management: Don't spend too long on any one question. If you're stuck, move on and come back later.
- Common Pitfalls: Don't confuse reliability and validity. Be aware of the impact of cultural bias and stereotype threat.
- Strategies: Read each question carefully, identify the key concepts, and use your knowledge to answer confidently.
Remember, you've got this! Stay calm, think clearly, and trust in your preparation.

#Free Response Question
Scenario: A school district is considering implementing a new standardized intelligence test to identify students for gifted programs. The district is also very diverse, with students from various cultural and socioeconomic backgrounds.
