Cognition and Intelligence Flashcards

The thinking side of Unit 2: concepts and prototypes, algorithms and heuristics, the biases and errors that distort judgment, creative thinking, and how intelligence is defined and measured. Covers Kahneman and Tversky's heuristics, functional fixedness, framing, theories of intelligence from Spearman to Gardner and Sternberg, and what makes a test standardized and fair.

What is a concept in cognitive psychology?

Tap to reveal answer

A mental grouping of similar objects, events, ideas or people (e.g., the category "furniture").

Tap to see question

What is a prototype?

Tap to reveal answer

The most typical example of a concept, used to judge whether new items belong (e.g., a robin as the prototype bird).

Tap to see question

How does an algorithm differ from a heuristic?

Tap to reveal answer

An algorithm is a step-by-step procedure that guarantees a solution but can be slow. A heuristic is a mental shortcut that is faster but more prone to error.

Tap to see question

What is the availability heuristic?

Tap to reveal answer

Judging how likely an event is by how easily examples come to mind (e.g., overestimating the risk of plane crashes after heavy news coverage).

Tap to see question

What is the representativeness heuristic?

Tap to reveal answer

Judging how likely something is by how well it matches a prototype, often while ignoring base rates.

Tap to see question

What is confirmation bias?

Tap to reveal answer

The tendency to seek out and favor information that supports what you already believe and to overlook evidence against it.

Tap to see question

What is functional fixedness?

Tap to reveal answer

The tendency to think of objects only in terms of their usual function, which blocks creative solutions (e.g., not seeing a coin as a screwdriver).

Tap to see question

What is a mental set?

Tap to reveal answer

Approaching a problem in a way that has worked before, even when a different approach would work better.

Tap to see question

What is the framing effect?

Tap to reveal answer

The way a choice is worded changes decisions, as when a treatment with a 90% survival rate is preferred to one with a 10% death rate.

Tap to see question

What is the gambler's fallacy?

Tap to reveal answer

The belief that past random events change the odds of future ones (e.g., thinking a coin is due to land heads after several tails).

Tap to see question

What is the sunk-cost fallacy?

Tap to reveal answer

Continuing to invest in something because of what has already been spent, even when quitting would be the better choice.

Tap to see question

What is insight in problem solving?

Tap to reveal answer

A sudden realization of a problem's solution, as opposed to working toward it step by step.

Tap to see question

How does convergent thinking differ from divergent thinking?

Tap to reveal answer

Convergent thinking narrows the options to a single best answer. Divergent thinking generates many possible answers and is linked to creativity.

Tap to see question

What did Charles Spearman mean by general intelligence (g)?

Tap to reveal answer

A single general ability that underlies performance on all kinds of mental tests, which is why scores on different tests tend to correlate.

Tap to see question

What did Howard Gardner propose about intelligence?

Tap to reveal answer

That there are multiple, relatively independent intelligences, such as linguistic, logical-mathematical, musical, spatial, bodily-kinesthetic, interpersonal, intrapersonal and naturalist.

Tap to see question

What are the three parts of Robert Sternberg's triarchic theory?

Tap to reveal answer

Analytical intelligence (academic problem solving), creative intelligence (generating novel ideas) and practical intelligence (handling everyday tasks).

Tap to see question

How does fluid intelligence differ from crystallized intelligence?

Tap to reveal answer

Fluid intelligence is the ability to reason quickly and abstractly and tends to decline in later adulthood. Crystallized intelligence is accumulated knowledge and verbal skill and tends to grow with age.

Tap to see question

How was the original intelligence quotient (IQ) calculated?

Tap to reveal answer

Mental age divided by chronological age, multiplied by 100. William Stern proposed the formula and Lewis Terman applied it to his revision of Binet's test.

Tap to see question

On modern intelligence tests, what are the average score and standard deviation?

Tap to reveal answer

An average of 100 and a standard deviation of 15, so about 68% of people score between 85 and 115.

Tap to see question

What does it mean for a test to be standardized?

Tap to reveal answer

It is given and scored in a uniform way, and each score is interpreted by comparison with the results of a large pretested group.

Tap to see question

How does an achievement test differ from an aptitude test?

Tap to reveal answer

An achievement test measures what you have already learned. An aptitude test predicts your ability to learn a new skill.

Tap to see question

What is the Flynn effect?

Tap to reveal answer

The rise in average intelligence test scores across many countries over the past century.

Tap to see question

What is stereotype threat?

Tap to reveal answer

Worry about confirming a negative stereotype about your group, which can lower performance on tests.

Study Tips for Cognition and Intelligence

1

Write a one-line scenario for every heuristic and bias, then quiz yourself from the scenario side. The exam describes a decision and asks which shortcut explains it.

2

Contrast the intelligence theorists on one card each: Spearman's single g, Gardner's multiple intelligences, Sternberg's three parts. Questions often ask which theorist a claim supports.

3

Link intelligence testing to research methods. Reliability, validity and standardization are the same ideas you learned for experiments, applied to a test.

4

Practice reading a normal curve of IQ scores. Know that one standard deviation is 15 points and that 68% of scores fall between 85 and 115.
