  1. Psychology Oswayo Valley High School COGNITION an exercise for and about the brain

  2. Introduction Cognitive Psychology One Definition The study of higher mental processes such as attention, language use, memory, perception, problem solving, and thinking. Three Concepts Learning Thinking Remembering

  3. Cognitive Processes Step #2 - Thinking The maintaining of information over a period of time; the changing and reorganizing of stored information to create new information It is the “processing” stage

  4. Thinking UNITS OF THINKING Image: a visual, mental representation of an event or object; not an exact copy, but highlights of the original Symbol: an abstract unit of thought that represents an object or quality; an image with no concrete existence . ! ?

  5. Thinking UNITS OF THINKING, cont’d Concept: a label for a class of objects that have at least one attribute in common; concepts enable us to group large amounts of information fine arts

  6. Thinking UNITS OF THINKING, cont’d Prototype: an example of a concept that best exemplifies that concept; an example that has the most characteristics of that particular concept

  7. Thinking UNITS OF THINKING, cont’d Rule: a statement about relationships between concepts; a complex unit of thought For every action there is an equal and opposite reaction Units of thinking provide an economical and efficient way for people to represent reality, to manipulate and reorganize it, and to devise new ways of acting

  8. An old money-lender offered to cancel a merchant’s debt and keep him from going to prison if the merchant would give the money-lender his lovely daughter. Horrified yet desperate, the merchant agreed to let Providence decide. The money-lender said he would put a black pebble and a white pebble in a bad and the girl would draw one. The white pebble would cancel the debt and leave her free. The black one would make her the money-lender’s, although the debt would be canceled. If she refused to pick, her father would go to prison. From the pebble-strewn path they were standing on, the money-lender picked two pebbles and quickly put them in the bag, but the girl saw he had picked two black ones. What would you have done if you were the girl?

  9. Thinking KINDS OF THINKING Directed Thinking: thinking with a systematic and logical attempt to reach a specific goal or answer Non-Directed Thinking: thinking with a free flow of thoughts with no particular plans; depends more on images

  10. KINDS OF THINKING, cont’d Metacognition: the awareness of one’s own cognitive processes; “thinking” about “thinking”

  11. Naomi, Marquita, and Kim are planning to go to a party, and they want to prepare for the party together. The party is across the street from Naomi’s home, so the three meet there an hour before the party. When, at the end of the hour, they are ready to go to the party, they discover that is has started to rain heavily. None of them wants to get wet because they are all wearing nice clothing. Unfortunately they have one umbrella for the three of them, and the umbrella is big enough to protect only two people from the rain. How can all three of them get to the party without becoming drenched? • Imagine that you are a doctor. One of your patients has a stomach tumor that must be destroyed if the patient is to live. Certain rays will destroy the tumor if they are intense enough. To reach the tumor, however, the rays need to pass through the healthy tissue that surrounds it, and at the intensity needed to destroy the tumor, the rays will also destroy the healthy tissue. How can you use the rays to destroy the tumor without damaging the healthy tissue? • Imagine that you are in a room with a candle, a box of matches, and some thumbtacks. Your task is to use these objects to attach the candle to the wall. How do you do it? • Imagine that you are in a room in which two strings are hanging from the ceiling. Your task is to tie the two strings together, but they are so far apart that you cannot reach both of them at the same time. The only other object in the room is a pair of scissors. How can you tie the strings together? • An airplane crashes on the border between the United States and Mexico. Where are the survivors buried?

  12. Thinking APPROACHES TO PROBLEM SOLVING Algorithm: a specific procedure that, when used properly and in the right circumstances will always lead to the solution of a problem Trial and Error • Heuristics: rules of thumb that often, but not always, lead to the solution of a problem • In the news we see people winning the lottery all the time and overestimate our chances of winning it. • I have flipped a coin 10 times and it has landed on tails every time; the odds are it land on heads the 11th time

  13. Thinking APPROACHES TO PROBLEM SOLVING, cont’d Difference Reduction: identify our goal, where we are in relation to it, and the direction we must go to move closer to it Means-End Analysis: breaking a problem into parts and then try to solve each part, putting the results together

  14. Thinking APPROACHES TO PROBLEM SOLVING, cont’d Working Backward: identify the goal, then work back to the present condition to determine the best course of action Analogies: using similar situations and/or solutions to solve new problems

  15. Thinking OBSTACLES TO PROBLEM SOLVING Mental Sets: the tendency to respond to a new problem with an approach that was used with similar problems; leads to rigidity

  16. OBSTACLES TO PROBLEM SOLVING , cont’d Convergent Thinking: thought that is limited to available facts Functional Fixedness: the tendency to think of an object as being useful only for the function that the object is usually used for

  17. OVERCOMING THE OBSTACLES Flexibility: the ability to overcome rigidity Creativity: the ability to use information in new and original ways Recombination: rearranging the elements of a problem to arrive at an original solution Insight: the apparent sudden realization of a solution Incubation: arriving at the solution to a problem without working consciously on the problem

  18. ABCDEs of PROBLEM SOLVING Assess the problem Brainstorm approaches to the problem Choose the approach that seems most likely to work Do it – try the approach Evaluate the approach and the solution

  19. DECISION MAKING AND JUDGMENT Weighing the pros and the cons Representative Heuristics: people make decisions about a sample according to the population that the sample appears to represent Availability Heuristics: people make decisions based on information that is available to them in their immediate consciousness Anchoring Heuristics: people make decisions based on the wording of the situation or problem

  20. DECISION MAKING AND JUDGMENT • Overconfidence: people tend to have a great deal of confidence in their decisions even if they are wrong • They are unaware of how flimsy their supporting evidence is • They tend to pay attention to examples that confirm their opinions and ignore examples that do not • They tend to bring about things they believe in
