How Spearman's g-factor influences modern intelligence testing.

📚 Quick Study Guide

• 🧠 Spearman's g-factor: Represents general intelligence, influencing performance across various cognitive abilities.
• 🔢 Factor Analysis: Statistical method used by Spearman to identify 'g' by observing positive correlations among different tests.
• 📈 Positive Manifold: The phenomenon where scores on different cognitive tests tend to correlate positively, supporting the existence of 'g'.
• 🧪 Modern Relevance: 'g' remains influential in test development, interpretation, and understanding the structure of intelligence.
• 📊 Hierarchical Models: Contemporary models often incorporate 'g' at the top, with more specific abilities branching out below.
• 💡 Criticisms: The unitary view of intelligence has faced challenges; some argue for multiple intelligences or broader cognitive profiles.
• 📝 Applications: Used in educational settings and employment to predict performance based on underlying cognitive abilities.
