answer
retrieval
question
handing in an essay test and then remembered several other things that you could have said
answer
example of retrieval
question
the set of mental operations that people perform on sensory information to convert that information into a form that is usable in the brain's storage system
answer
encoding
question
model of memory that assumes that information that is more "deeply processed" - or processed according to its meaning, rather than just the sound or physical characteristics of the word(s) - will be remembered more efficiently and for a longer period of time
answer
levels-of-processing model of memory
question
the very first stage of memory, the point at which information enters the nervous system through the sensory systems

question
Sperling developed, showed grid of letters again but immediately sounded a high, medium, or low tone just after the grid was shown. subjects were told to report the top row of letters if they heard the high tone, the middle row for the medium tone, or the lowest row for the low tone. couldn't look at one row in advance found: subjects could accurately report any of the 3 rows, entire grid= iconic memory the capacity of iconic memory is everything that can be seen at one time
answer
partial report method

question
people were told to look at an imaginary island with several landmarks like hut, lake, and grassy area. after memorizing it, they were asked to imagine a specific place (hut) and then "look" for another one (lake). when they mentally "reached" the 2nd place, they pushed a button that recorded reaction time. the greater the physical distance, the longer it took because they were scanning their mental image like a real, physical map
answer
Findings of Kosslyn's "imaginary island" study
question
ideas that represent a class or category of objects, events, or activities ex: dogs come in all shapes, sizes, and colors. yet most people have no trouble recognizing dogs as dogs, even though they may never before have seen that particular breed of dog.
answer
concepts
question
a concept that closely matches the defining characteristics of that concept/most basic examples of concepts -develop according to the exposure a person has to objects in that category ex: when we think of fruit we think of an apple because we're so used to seeing those but people from tropical areas might say coconut because they're more common
answer
prototype
question
also known as trial and error. refers to trying one solution after another until finding one that works ex: someone forgot the PIN for their card, they can try one combination after another until they find the one that works, if they have only a few PIN numbers that they usually use.
answer
mechanical solution
question
very specific, step-by-step procedures for solving certain types of problems. will always result in a correct solution if one exists to be found and you have enough time to find it
answer
algorithmic method
question
mathematical formulas, librarians organizing books on shelves, Rubik's cube
answer
example of algorithmic method
question
educated guess based on prior experiences that helps narrow down the possible solutions for a problem. also known as "rule of thumb" - simple rule that is intended to apply to many situations ex: if a student is typing a paper in a word-processing program and wants to know how to format the page, he or she could try to read an entire manual on the word-processing program. that would take a long time, instead the student could use an internet search engine or type format into the help feature's search program. doing either action greatly reduces the amount of information the student will have to look at to get an answer.
answer
heuristics
question
assumption that any object (or person) sharing characteristics with the members of a particular category is also a member of that category
answer
representative heuristics
question
classifying plants, error with humans: assuming dark skin=Africa, red hair=temper, blue-eyed blondes=Sweden
answer
example of representative heuristsics
question
estimating the frequency or likelihood of an event based on how easy it is to recall relevant information from memory or how easy it is to think of related examples
answer
availability heuristics
question
read entire textbook and asked to estimate how many words in the book start with "k" and how many have "k" as the 3rd letter, which place is more frequent and the ratio based on how easy it is
answer
example of availability heuristics
question
the tendency to search for evidence that fits one's beliefs while ignoring any evidence that doesn't fit those beliefs
answer
confirmation bias
question
believers in ESP tend to remember the few studies that seem to support their beliefs and psychic predictions that worked out while at the same time "forgetting" the cases in which studies found no proof of psychics made predictions that failed to come true. they remember only that which confirms their bias toward a belief in the existence of ESP multitasker: driving and texting only remembers good driving times and not the near misses
answer
example of confirmation bias
question
a block to problem solving that comes from thinking about objects only in terms of their typical function -tendency for people to persist in using problem-solving patterns that have worked for them in the past
answer
functional fixedness
question
searching for only one item to get the job done (screwdriver) while not noticing other objects that could do the same job (butter knife, key, dime)
answer
example of functional fixedness
question
type of thinking in which a problem is seen as having only one answer, and all lines of thinking will eventually lead to that single answer, using previous knowledge and logic
answer
convergent thinking
question
the ability to learn from one's experiences, acquire knowledge, and use resources effectively in adapting to new situations or solving problems
answer
