Defining and Measuring Human Intelligence:

Intelligence is a controversial topic; the lecture will explore its definitions and cultural understandings.

Examination of lay theories versus academic definitions of intelligence.

Historical Context of Intelligence Testing:

Testing preceded theoretical definitions; understanding this connection is vital.

Discussion will include significant figures in intelligence theory (e.g., Spearman, Cattell).

Key Concepts in Intelligence:

The concept of general intelligence or "g".

Differentiation between types of intelligence (e.g., fluid vs. crystallized intelligence).

Cultural Influences:

Intelligence perceptions differ across cultures; the need for culturally sensitive measures.

Examples of how different cultures view intelligence and problem-solving.

Challenges in measuring intelligence universally due to varied cultural contexts.

Notable Theories and Researchers:

Francis Galton: Links between intelligence and genetics.
