Intelligence Study Guide

📖 Core Concepts Intelligence – Ability to perceive/infer information, retain it as knowledge, and adapt behavior in context. Fundamental capacities – Abstraction, logic, understanding, self‑awareness, learning, emotional knowledge, reasoning, planning, creativity, critical thinking, problem‑solving. Fluid vs. Crystallized intelligence – Fluid: novel problem‑solving, reasoning on the fly. Crystallized: accumulated knowledge and skills. g factor – A single general factor that accounts for the common variance among diverse cognitive test scores. Intelligent Agent (AI) – System that perceives its environment and selects actions to maximize success. Emotional, Social, Moral intelligence – Distinct but related capacities for handling emotions, social cues, and ethical judgments respectively. Cattell‑Horn‑Carroll (CHC) model – Hierarchical framework organizing human cognitive abilities (fluid reasoning, perceptual speed, verbal abilities, etc.). 📌 Must Remember APA 1995 consensus: Intelligence = ability to understand complex ideas, adapt, learn from experience, reason, and overcome obstacles. IQ tests were created to screen for intellectual disability; later used for immigration, military, employment. g factor is observed both in humans and several non‑human species. Emotional intelligence = clear expression of emotions + accurate reading of others’ emotions. Social intelligence ≠ emotional intelligence, though they are related. Artificial intelligence ≠ general intelligence; current AI excels in narrow tasks (e.g., chess, protein folding). Heritability of IQ is debated; genetics does not explain average IQ differences between racial groups. 🔄 Key Processes Assessing Human Intelligence Administer a standardized IQ test. Compute a composite score (often expressed as a deviation IQ, mean = 100, SD = 15). Interpret in light of fluid and crystallized sub‑scores and the CHC hierarchy. Intelligent Agent Decision Loop Perceive environment → collect data. Interpret data (apply learned models). Choose an action that maximizes expected success. Act on the environment. Learn from outcome → update models. 🔍 Key Comparisons Fluid vs. Crystallized – Fluid: novel reasoning; Crystallized: learned knowledge. Emotional vs. Social intelligence – Emotional: managing/reading emotions; Social: interpreting social cues, motivations, self‑in‑social contexts. Human IQ vs. AI performance – Human IQ: broad, adaptive cognition; AI: high proficiency on narrow, well‑defined tasks, lacking general adaptability. ⚠️ Common Misunderstandings “IQ = overall intelligence.” → IQ captures aspects linked to academic performance, not all intelligence domains (e.g., moral, social). “Genetics fully explains IQ differences.” → Heritability is contested; genetics does not account for racial group averages. “Current AI has human‑like understanding.” → AI lacks general intelligence; it follows learned patterns within narrow domains. 🧠 Mental Models / Intuition g factor as a “common core” – Imagine all test scores pulling on a single elastic band; the band’s tension ($g$) reflects overall cognitive ability. Intelligent Agent as a feedback loop – Think of a thermostat: senses temperature, decides heating/cooling action, acts, then re‑senses. 🚩 Exceptions & Edge Cases IQ validity – While predictive of academic success, IQ does not fully capture creativity, moral reasoning, or real‑world problem solving. Animal g factor – Presence of a general factor in some species does not imply human‑level cognition. AI benchmarks – Success in games or protein folding does not guarantee competence in unrelated tasks. 📍 When to Use Which Choose IQ testing when you need a standardized measure of academic‑related cognition. Use emotional/social intelligence assessments for roles demanding interpersonal interaction (e.g., leadership, counseling). Apply CHC framework when categorizing specific ability deficits or strengths (e.g., fluid reasoning vs. verbal knowledge). Select an AI model when the problem is well‑defined, data‑rich, and performance can be measured against a clear objective. 👀 Patterns to Recognize Multiple‑domain language – “Intelligence” is often qualified (e.g., emotional, social, moral) → look for the specific domain being tested. g factor mentions → signals a discussion of general cognitive ability across tests or species. “Adaptation” or “flexible learning” → clue that the passage is describing AI or fluid intelligence. 🗂️ Exam Traps Distractor: “AI has achieved general intelligence.” → Wrong; current AI is narrow. Distractor: “High IQ guarantees high moral intelligence.” → Wrong; moral intelligence is a separate construct. Distractor: “Heritability proves genetics fully determines IQ.” → Wrong; heritability is debated and does not explain group differences. Distractor: “Emotional intelligence = ability to solve math problems.” → Wrong; emotional intelligence concerns emotion handling, not analytical problem solving.
