Chapter 8- Thinking and Decision Making

Question 1

Cognition

Answer 1

“to know”

Mental processes involved in acquiring, processing, and storing knowledge

Question 2

Cognitive Psychology

Answer 2

The science of how people think, learn, remember, and perceive

Question 3

Mental Representations

Answer 3

A structure in our mind- such as an idea or image- that stands for something else, such as the external object or thing
Not present
Many types
Allows us to:
Think about and remember things in the past
Imagine things in the future
Think about abstract ideas, like love, truth justice

Question 4

The Visual System

Answer 4

Located mostly in the occipital lobes
Older than the verbal system
Develops before verbal ability
We see before we talk

Question 5

Visual Imagery

Answer 5

Visual representations created by the brain after the original stimulus is no longer present
Brain during visual imagery is activated in same way as it is during visual perception
Therefore, difficult to distinguish between a brain perceiving something and a brain imagining seeing the same thing
Crucial for some cognitive tasks involved in interpreting spatial relationships

Question 6

Imagining Outcomes

Answer 6

Imagining outcomes makes them more likely to happen
If you form a mental image of an ideal performance, you are more likely to perform that activity better
Performance is improved because the brain is primed by images of the success, the pathways are activated in advanced

The brain is activated in the same way while imagining a task as it is while performing a task

Question 7

Mental Rotation

Answer 7

The process of imagining an objet rotating in 3D space

Takes 2.5 seconds to determine if same or different

Have to conjure mental picture and manipulate the image to make a judgement about its spatial properties

Boys and men do better than girls and women

May not only be gender directly that leads to differences in spatial ability, but how you identify. People who self-identify as “masculine” have higher spatial ability scores than those who identify as “feminine”

Question 8

Cause of the Gender Difference in Spatial Ability

Answer 8

Levels of male sex hormone, testosterone
Female rats with injected testosterone during development performed better on spatial tasks, maze running
Relationships in humans among testosterone, gender, and spatial ability is complex and not linear
In humans, females with high levels and males with low levels of testosterone perform better on spatial tasks

Question 9

Major Function of Thought

Answer 9

To organize and classify our perceptions into categories

Humans organize their environment by naming things and giving them labels

Question 10

Concept

Answer 10

The basic unit of knowledge
A mental grouping of objects, events, or people
Help organize perceptions of the world

Question 11

We can store and process concepts in two ways

Answer 11

in a hierarchy and by parallel distributed processing

Question 12

Concept Hierarchy

Answer 12

An arrangement of related concepts in a particular way
Some being general, others specific
Helps order and understand the world
Example: A dog, Goldie, is a “Golden Retriever,” which is a “dog”, which is an “animal”, which is a “living thing”

Question 13

2) Parallel Distributive Processing (PDP)

Answer 13

Associations between concepts activate many networks or nodes at the same time
Concepts are activated in the network based on how strongly associated or connected they are to each other
Arranged by similarity
Location of a concept is based on its relation to other concepts
Example: Animals such as bird and fish are closer to each other and farther away from plants such as trees and flowers

Question 14

Category

Answer 14

A concept that organizes other concepts around what they all share in common
Example: All things that move and eat are “animals”. All things that grow out of the Earth and do not eat are “plants”
Can either be concrete or abstract

Question 15

Concrete categories:

Answer 15

triangles, cars

Question 16

Abstract categories

Answer 16

good, consciousness

Question 17

Prototypes

Answer 17

The best fitting examples of a category

Ex: Robin is a better prototype for the category “bird” than ostrich

Question 18

Reasoning

Answer 18

The process of drawing inferences or conclusions from principles and evidence
Anytime we use the word “because”
Sometimes allows to draw sound, correct conclusions but not always the case

Question 19

Cognitive psychologists distinguish between two kinds of reasoning drawn from formal logic

Answer 19

Deductive and Inductive

Question 20

Deductive Reasoning

Answer 20

Reasoning from general statements of what is known to specific conclusions
Specific conclusion is always correct if the general statement is true
When scientists make specific predictions from general theories
Example: A) All humans are mortal B) Ryan is mortal C) Therefore, Ryan is mortal

Question 21

Inductive Reasoning

Answer 21

Drawing general conclusions from specific evidence
Less certain conclusions than deductive
Highly likely conclusions
Used when scientists develop theories because they offer general statements that explain many facts or observations
Example: “All the peaches I have eaten have been sweet, therefore all peaches are sweet”
All it takes is one unsweet peach to undermine that conclusion

Question 22

Casual Inferences

Answer 22

Judgements about whether one thing causes another thing
Often used when we use inductive reasoning
Example: “Every time I get chilled, I catch a cold. So getting chilled must cause colds”

Question 23

Confirmation Bias

Answer 23

The tendency to selectively attend to information that supports one’s general beliefs while ignoring information or evidence that contradicts one’s beliefs
Inductive reasoning + casual inferences

Question 24

Wason’s Test To See If People Are More Likely To Falsify or To Confirm Their Own Theories

Answer 24

Gave students the task of determining the hidden rule behind a sequence of three numbers/ triplet
Asked students to guess at the rule by writing down triplets that they thought conformed to it and the reason they selected them
Could make as many guesses and explanatory statements as they wished, until they thought they knew the rule
Then they wrote down what they thought the rule actually was
Actual rule was “the numbers in the triplet must increase in value”
23/29 incorrectly guessed at first
Participants who made an initial incorrect guess at the rule were more likely to rephrase the rule in subsequent guesses, rather than guessing an entirely new rule
Correct answers were more likely to arise when students tried to disconfirm the rule
This experiment shows that people are inclined to test only ideas that confirm their beliefs

Question 25

Critical

Answer 25

From the ancient Greek word kritikos | Means to question, to make sense of, and to be able to analyze or to be skilled at judging

Question 26

Critical Thinking

Answer 26

The process by which one analyzes, evaluates, and forms ideas “The ability to analyze facts, generate and organize ideas, defend opinions, make comparisons, draw inferences, evaluate arguments, and solve problems” Requires evaluation of evidence and arguments independently of one’s prior beliefs and opinions Closely related to scientific thinking and reasoning

Question 27

Qualities To Be a Critical Thinker

Answer 27

Interpreting Explaining Self-regulating

Question 28

Scientific Thinking

Answer 28

The process of using the cognitive skills required to generate, test, and revise theories Keeps beliefs and reality separate Belief is not the same as reality

Question 29

Metacognitive Thinking

Answer 29

Requires the ability to first think and then reflect on one’s own thinking Questioning one’s own thinking Knowing what you do and do not know Ability not universal

Question 30

Algorithm

Answer 30

step by step

Question 31

eureka insight

Answer 31

sudden

Question 32

heuristics

Answer 32

mental short cuts Methods for making complex and uncertain decisions and judgements Allows for quick and efficient decisions Ex: Crossing a street to not be hit by cars, we look both ways before going and make a judgement whether its safe or not

Question 33

There are two most common types of heuristics

Answer 33

the representativeness heuristic and the availability heuristic

Question 34

The Representative Heuristic

Answer 34

A strategy used to estimate the probability of one event based on how typical it is of another event Problems: Tendency to rely on this strategy instead of other types of evidence Ex: Personality descriptions that fit certain occupations were used to make probability judgements even when the base rates were given to participants

Question 35

2) The Availability Heuristic

Answer 35

A strategy we use to make decisions based on the ease with which estimates come to mind or how available they are to our awareness Often used when people make judgments about the aggressiveness of dog breeds Relies on immediate examples that comes to a person’s mind when evaluating a topic, concept, method, or decision

Question 36

Pit bull Study

Answer 36

Pit bulls have bad reputation Although they are involved in fatal dog attacks, German shepherds are more likely to be involved in fatalities Media coverage of pit bull attacks tends to be very vivid and thoughts of a snarling pitiful are easily called to mind Vividness and availability leads us to overestimate how likely certain events are

Question 37

Stuart McKelvie Experiment

Answer 37

Had participants listen to a list containing an equal number of men’s and women’s names One list version had all famous male names Other version had all famous female names Participants reported that there were more men on the list if they heard the version with famous men Reported that there were less women on the list if they heard the version with famous women The names of famous people stand out and become more prominent in memory, therefore participants had better recall The more available information is to our recall, the more likely we are to be biased towards it

Question 38

Rational Choice Theory

Answer 38

When given a choice between two or more options, humans will choose the one that is most likely to help them achieve their particular goals- the rational choice Based on principles of behaviourism Theorists held that people base financial decisions on a cost-benefit analysis: do the costs outweigh the benefits? If yes, we don't buy

Question 39

Evidence Against Rational Choice Theory

Answer 39

If people were rational they would realize that the odds of two events can never be higher than the odds of one of those events alone The odds of A and B occurring together can never exceed the odds of either A or B occurring separately Example: Linda is 31 years old, single, outspoken and very bright. She majored in philosophy. As a student, she was deeply concerned with issues of discrimination and social justice and participated in anti-nuclear demonstrations WHAT ARE THE ODDS OF EACH OF THE FOLLOWING: A) Linda is active in the feminist movement B) Linda is a bank teller C) Linda is a bank teller and is active in the feminist movement Its clear that A is more likely than B, we are likely to say that C is more likely than B. Shows that people sometimes ignore base rates and are biased by stereotypes and use short cuts to arrive quickly, but not rationally, at their conclusions

Question 40

Conjunction fallacy

Answer 40

Occurs when people say the combination of two events is more likely than than either event alone

Question 41

Learning a Second Language

Answer 41

Higher vocabulary in monolingual children than bilingual children Better executive functioning skills in bilingual children

Question 42

The Best Way to Learn a New Language

Answer 42

The earlier an individual is exposed to a language, the better Bilingual infants begin to learn about the properties of their two languages very early in life, before they actually begin to speak Humans are capable of learning two languages as one Even if children are not exposed to a bilingual environment from infancy, they can still easily learn a second language

Question 43

Subtractive Bilingualism

Answer 43

Loss of language fluency with second language learning Can be avoided if the minority language is supported at home and school ex: Children who were taught in English or French for the first three years of school had poorer language skills in their own native Inuktitut language, even after one year of school

Question 44

Sensitive Period

Answer 44

The younger a person is when they acquire the second language, the more proficiently they speak that language At age 7, learning a second language is difficult At ages 13 to 15, the sensitive period ends The length of time the immigrants had been in the United States did not affect the strength or thickness of their accent, but the age at which they had moved to the U.S did. If they were six when they immigrated and had been in the country for two years, they had much less of an accent than if they were 30 years old when they learned the language but been in the US for 10 years.

Question 45

Bilingual People

Answer 45

People who are fluent in two languages are capable of more efficient cognitive processing than the who speak only one language Bilingual speakers have a greater density of neurons in the language centres of the brain The earlier the second language is learned, the greater the neural density Are more skilled in theory of mind tasks than monolingual children Brains of people who learn a 2nd language early in life are more efficient at language processing and more similar when speaking in both languages than the brains of those who learn later If someone learns a 2nd language at the same time they learn their first language, the brain regions that are active during speech production overlap completely… doesn't happen when you learn 2nd language later in life

Question 46

Cognitive Tasks and Second Language

Answer 46

Those who spoke two languages performed better on cognitive tasks and continued to do so later in life Elderly speakers of two languages developed dementia more than four years later than others Support the view that stimulation from the environment- learning another language- can enrich our brains and enable them to process information more efficiently

Question 47

Reasoning in a Second Language

Answer 47

Students performed better in their native language when using deductive reasoning

Question 48

Second Language Acquisition and Metacognition

Answer 48

By age four, children understand that other people’s thoughts and ideas are different from their own Bilingual children are aware of what the person they are speaking to know and does not know
