“ A bat and ball cost$1.10. The bat costs $1 more than the ball. How much does the ball cost?”
“A man bought a horse for $60 and sold it for $70. Then he bought the same horse back for $80 and again sold it for $90.
How much money did he make in the horse business?”

Thinking
Cognition mental activity associated with processing,
understanding, and communicating information
Cognitive Psychology the study of these mental activities
concept formationproblem solvingdecision makingjudgement formation
study of both logical and illogical thinking
![Page 4: Myers’ PSYCHOLOGY (8th Ed) Chapter 10 Thinking v. Intuition and Language.](https://reader035.fdocuments.in/reader035/viewer/2022062515/56649d0a5503460f949dd1dc/html5/thumbnails/4.jpg)
ThinkingConcept
mental grouping of similar objects, events, or peopleaddress
• country, city, street, house• zip codes
Prototype the best example of a category
matching new items to the prototype provides a quick and easy method for including items in a category (as when comparing feathered creatures to a prototypical bird, such as a robin.)

Thinking
Algorithm methodical, logical rule or
procedure that guarantees solving a particular problem
contrasts with the usually speedier – but also more error-prone use of heuristics
![Page 6: Myers’ PSYCHOLOGY (8th Ed) Chapter 10 Thinking v. Intuition and Language.](https://reader035.fdocuments.in/reader035/viewer/2022062515/56649d0a5503460f949dd1dc/html5/thumbnails/6.jpg)
Thinking
Heuristic rule-of-thumb strategy that often
allows us to make judgements and solve problems efficiently
usually speedier than algorithms more error-prone than algorithms sometimes we’re unaware of using
heuristics

Thinking
Insight sudden and often novel realization of the
solution to a problem contrasts with strategy-based solutions
Confirmation Bias tendency to search for information that
confirms one’s preconceptionsFixation
inability to see a problem from a new perspective
impediment to problem solving

Thinking
Mental Set tendency to approach a problem in a particular way
especially a way that has been successful in the past but may or may not be helpful in solving a new problem
![Page 15: Myers’ PSYCHOLOGY (8th Ed) Chapter 10 Thinking v. Intuition and Language.](https://reader035.fdocuments.in/reader035/viewer/2022062515/56649d0a5503460f949dd1dc/html5/thumbnails/15.jpg)

The Three-Jugs Problem
Solution: a) All seven problems can be solved by the equation shown in (a): B-A-2C= desired volume.
b) But simpler solutions exist for problems 6 and 7, such as A-C for problem 6.
![Page 18: Myers’ PSYCHOLOGY (8th Ed) Chapter 10 Thinking v. Intuition and Language.](https://reader035.fdocuments.in/reader035/viewer/2022062515/56649d0a5503460f949dd1dc/html5/thumbnails/18.jpg)
The Candle-Mounting Problem
Solving this problem requires recognizing that a box need not always serve as a container
![Page 19: Myers’ PSYCHOLOGY (8th Ed) Chapter 10 Thinking v. Intuition and Language.](https://reader035.fdocuments.in/reader035/viewer/2022062515/56649d0a5503460f949dd1dc/html5/thumbnails/19.jpg)
Heuristics
Representativeness Heuristic rule of thumb for judging the
likelihood of things in terms of how well they seem to represent, or match, particular prototypes
may lead one to ignore other relevant information
![Page 20: Myers’ PSYCHOLOGY (8th Ed) Chapter 10 Thinking v. Intuition and Language.](https://reader035.fdocuments.in/reader035/viewer/2022062515/56649d0a5503460f949dd1dc/html5/thumbnails/20.jpg)
Heuristics
Availability Heuristic estimating the likelihood of
events based on their availability in memory
if instances come readily to mind (perhaps because of their vividness), we presume such events are common
Example: airplane crash
![Page 21: Myers’ PSYCHOLOGY (8th Ed) Chapter 10 Thinking v. Intuition and Language.](https://reader035.fdocuments.in/reader035/viewer/2022062515/56649d0a5503460f949dd1dc/html5/thumbnails/21.jpg)
Thinking
Overconfidence tendency to be more confident
than correct tendency to overestimate the
accuracy of one’s beliefs and judgements
![Page 22: Myers’ PSYCHOLOGY (8th Ed) Chapter 10 Thinking v. Intuition and Language.](https://reader035.fdocuments.in/reader035/viewer/2022062515/56649d0a5503460f949dd1dc/html5/thumbnails/22.jpg)
Thinking
Framing the way an issue is posed how an issue is framed can
significantly affect decisions and judgements
Example: What is the best way to market ground beef- As 25% fat or 75% lean?
![Page 23: Myers’ PSYCHOLOGY (8th Ed) Chapter 10 Thinking v. Intuition and Language.](https://reader035.fdocuments.in/reader035/viewer/2022062515/56649d0a5503460f949dd1dc/html5/thumbnails/23.jpg)
Thinking
Belief Bias the tendency for one’s preexisting
beliefs to distort logical reasoning sometimes by making invalid
conclusions seem valid, or valid conclusions seem invalid
Belief Perseverance clinging to one’s initial conceptions after
the basis on which they were formed has been discredited
![Page 24: Myers’ PSYCHOLOGY (8th Ed) Chapter 10 Thinking v. Intuition and Language.](https://reader035.fdocuments.in/reader035/viewer/2022062515/56649d0a5503460f949dd1dc/html5/thumbnails/24.jpg)

Language
Morpheme in a language, the smallest unit that
carries meaning may be a word or a part of a word

Semantics the set of rules by which we derive
meaning from morphemes, words, and sentences in a given language
also, the study of meaningSyntax
the rules for combining words into grammatically sensible sentences in a given language

LanguageBabbling Stage
beginning at 3 to 4 months the stage of speech development in
which the infant spontaneously utters various sounds at first unrelated to the household language
One-Word Stage from about age 1 to 2 the stage in speech development
during which a child speaks mostly in single words
![Page 32: Myers’ PSYCHOLOGY (8th Ed) Chapter 10 Thinking v. Intuition and Language.](https://reader035.fdocuments.in/reader035/viewer/2022062515/56649d0a5503460f949dd1dc/html5/thumbnails/32.jpg)
Language
Two-Word Stage beginning about age 2 the stage in speech development
during which a child speaks mostly two-word statements
Telegraphic Speech early speech stage in which the child
speaks like a telegram – “go car” – using mostly nouns and verbs and omitting “auxiliary” words
![Page 33: Myers’ PSYCHOLOGY (8th Ed) Chapter 10 Thinking v. Intuition and Language.](https://reader035.fdocuments.in/reader035/viewer/2022062515/56649d0a5503460f949dd1dc/html5/thumbnails/33.jpg)
