Chapter 8 Psych Flashcards
concepts
mental representations of specific objects, events, or ideas (apple pie vs. blueberry pie)
categories
larger groups of concepts based on their similarity to one another (all pies)
classical categorization approach
we group together objects & events into categories because they share common defining features (dogs bark, 4 legs, animal)
graded membership
some members are better representatives than others
sentence verification technique
experiment asking true or false like a ‘robin’ is a bird, people are faster to say yes rather than a penguin is a bird
prototype
the average of all members of a category (seeing a motorcycle unlike one you’ve seen before but still knowing that its a motorcycle)
semantic network
connection to similar concepts will be closer than ones with dissimilar concepts (ex. bird-fly-beak)
linguistic relativity (or the whorfian hypothesis)
the idea that differences in languages between culture change the way members of those cultures actually perceive the world
algorithm
a slow, logical, and step-by-step solution to a problem based on a set of rules
Heuristics
relying on past experience to make a quick and reasonable guess as to the problems solution (good for guessing)
cognitive obstacles
when you can’t think of the normal solution (9 dot obstacle)
functional fixedness
the tendency to treat objects as only serving one function
representativeness heuristic
the assumption that all members of a category share the same features based on ones experience with only a small number of category members (getting a jason thinking he’s rude then assuming all other masons are rude)
base rates/ conjunction fallacy
same group of people that do a certain thing will be smaller than people don’t
the availability heuristic
making judgements about the frequency with c=which events occur based on how easy it is for us to think of examples (more words start with K rather than have it as a 3rd letter)
the anchoring effect
restrictions in a persons numerical judgements based solely on their exposure to some number (high # high estimate, low # low estimate)
framing effects
when the mere wording of a question has a biasing influence on our judgements or decision making
