Question 1: According to David Wechsler's definition presented in the lecture, intelligence is best described as:
Only the learned skills and knowledge a person acquires through education.
A single innate factor that determines all cognitive performance.
A fixed set of sensory abilities unrelated to real-world tasks.
A global capacity to act purposefully, think rationally, and deal effectively with the environment.
Question 2: Spearman’s two-factor theory explains test performance as a combination of:
Only seven independent primary abilities with no general factor.
Operations, contents, and products combined into dozens of factors.
Separate genetic and environmental intelligence components explicitly measured by tests.
A general ability (g) shared across tasks and task-specific abilities (s).
Question 3: Thurstone’s primary mental abilities model would predict which of the following job-task mappings?
A pilot needing strong spatial visualization and perceptual speed for cockpit tasks.
An accountant uses only inductive reasoning and not numerical ability.
A graphic designer requires only memory and no spatial skills.
All jobs depend only on a single general factor, so job-specific mapping isn't useful.
Question 4: What role does factor analysis play in building intelligence theories, as described in the lecture?
It directly measures innate genetic intelligence without relying on tests.
It identifies underlying cognitive factors by examining correlations among many test scores.
It proves which theory of intelligence is absolutely true across all contexts.
It replaces behavioral testing by predicting job performance from brain scans alone.
Question 5: Guilford’s Structure of Intellect model is distinctive because it:
Asserts intelligence is a single unitary g factor with no subcomponents.
Limits intelligence to seven primary abilities only.
Combines operations, contents, and products to create many specific cognitive factors.
Focuses solely on the role of schooling in forming intelligence.
Question 6: Which statement best reflects the lecture’s guidance on innate versus learned components of intelligence?
General ability (g) tends to be more stable, while many specific skills (s and primary abilities) are learned and improvable.
All intelligence is entirely fixed at birth and cannot be changed by practice.
Innate and learned components are indistinguishable and never separable in practice.
Only learned skills matter; innate factors are irrelevant for performance.
Question 7: The lecture warns that models of intelligence have limits because:
Factors overlap and methods shape outcomes, so no model captures every aspect without simplification.
Every model is completely wrong and should be discarded.
Intelligence has no measurable structure and is purely subjective.
All models always agree exactly on the same set of factors.
