Associative Thinking-- includes indirected and uncontrolled thinking such as occur in reveries and dreams.
a.Autistic thinking ( also called
daydreaming )b. Nightdreaming
( due to unconscious impulses )C. Imagination
(process of creating objects or events)D. Eidetic imagery
( Photographic Minds )

Directed Thinking-- thinking oriented towards a goal – as in reasoning about a problem.
a.Critical thinking (crucial judgment or
evaluation of something )
b. Creative Thinking ( involves the ability to
produce new forms in art )
- Preparation- Incubation- Illumination- Verification

Directed Thinking
c. Brainstorming ( technique which involves grouping people )d. Reasoning( process of logical thinking )e. Problem Solving( process used in discovering the correct sequence of alternatives leading to a goal )

Algorithms-- fixed set of rules that, if followed correctly, will eventually lead to a solution.
Heuristics-- the rules of thumb, or clever and creative mental shortcuts
Changing One’s Mental Set Using Analogies
-- strategy for finding a similarity between the new situation and an old
Forming Subgoals-- a strategy that involves breaking down the overall problem

> Think Accurately: Separate Facts From Mere
Information
> Separate Facts Into Two Classes: The Important And The
Unimportant, Or, The Relevant And The Irrelevant
Accurate Thinking Involves Two Fundamental:

Once a problem is represented (whether its through words, static images, or mental models), we try out possible solutions and test to see if they work. If the problem is solved, life goes on. If not, we return to the proverbial drawing board to come up with new ideas.

Problems with Problem Solving
Mental setThe tendency to use a
strategy that has worked in the past
Functional FixednessA tendency to think of
objects only in terms of their usual functions, a limitation that
disrupts problem solving

Problems with Problem Solving
Confirmation BiasThe inclination to search only
for evidence that will verify one’s beliefs
Belief PerseveranceThe tendency to cling to beliefs
even after they have been discredited
Anderson (1980)

Try to make best choice from alternatives
Utility: value of given outcome
Probability: likelihood you’ll achieve it
Representativeness HeuristicA tendency to estimate the
likelihood of an event in terms of how typical
(how similar to the prototype) it seems
Availability HeuristicA tendency to estimate the likelihood of an event in
terms ofhow easily instances of it can

What is it?- a form of communication consisting of a system of sounds, words, meanings, and rules for their combination.
> Formal system of communication-- Spoken,written, and/or gestures
> Between 5,000 and 6,000 languages, worldwide
-- Most languages also have many dialects
Powerpoint TemplatesPage 21
-- Semantic There are separate units in a language
and these units have meaningPhoneme: basic building block of spoken languageMorpheme: smallest unit that carries meaning
-- Generative Combing language in novel
ways
-- DisplacementThe property of language that
accounts for the capacity to communicate about matters that are
not in the here-and-now
Powerpoint TemplatesPage 22
Grammar-- The rules of a language-- Syntax
> Specifies how words can be arranged-- Semantics
> Specifies how meaning is understood & communicated
Transformational grammar-- Any one thought
can be expressedin different ways
Powerpoint TemplatesPage 23
No one disputes the stages of language development
But there are two main questions in terms of what it all means
-- Is language acquisition a product of nature or
nurture?-- Which comes first –
language or thought?
Powerpoint TemplatesPage 24
• Is it nature or nurture?– Skinner vs. Chomsky
• Skinner: Children learn language the way animals learn mazes
• Chomsky: The brain is hard-wired for learning lang.
– Critical period• During the first few years of life, we are most
receptive to language learning
• What comes first – thought or language?» Both: sometimes children use
words to communicate what they already know
and sometimes they form concepts to fit the words they hear
