Cognition Princeton Review Crack-a-lackin Tasha Wright
2
Sensory Memory =gateway between perception and memory very limited Iconic=visual (1/10ths of a second) Echoic=auditory (3-4 seconds)
3
Sensory Memory Dos Based on how you perceive things Ex. Jump rope: at many points at once =visual persistence
4
George Sperling and partial report G Z E P R K O D B T X F Paired with different pitched sounds Better with lower pitch Short-term visual (iconic) memory
5
Short-Term Memory Few seconds to about a minute Acoustically coded Seven parts (+/- 2) Ex. Telephone numbers Chunking=grouping items
6
Rehearsal Maintenance=simple repetition for the short term Elaborative=organization and understanding for long-term use Can decay by interference
7
Remembering Lists: Primacy=remembering the first items Recency=remembering the last items (fades in about a day) serial position effect
8
Long-Term Memory Semantically encoded memories=encoded in the form of word meanings can be semantically plus visually or acoustically encoded Ex. Song lyrics
9
Episodic memory=events that we ourselves have experienced Semantic memory=fact based memory Procedural memory=skills and habits
10
Types of LTM State-dependent memory: more likely to be recalled if the attempt to retrieve it occurs in a situation similar to the situation in which is was encoded Flashbulb memories: very deep, vivid memory in the form of a visual image associated with a particular emotionally arousing event Working memory: the part of LTM that is currently in use
11
Memory Changing Reconstruction=fitting events together that seem likely can be caused by source amnesia Framing=repeated suggestions and misleading questions that create false memories problems in trials
12
Language Arbitrary words don’t sound like the ideas they convey Additive structure words into phrases, phrases to sentences, sentences to paragraphs, etc. Multiplicity of structure can be analyzed in many ways Production nearly endless combination of words Dynamic constantly changing and evolving
13
Phonemes=smaller units of speech sounds Morphemes=combination of phonemes Grammar=set of rules of language Syntax=organizing morphemes into meaningful language Semantics=word choice
14
Acquiring Language (Infants) Holophrases=single terms that are applied to a broad category of things Ex. All women are “mama” this is overextension (2 year olds) Telegraphic speech=lack many parts of speech Ex. “mommy food” (3 years old) Know over 1,000 words overgeneralization errors Ex. I goed to store
15
Noam Chomsky and Transformational grammar Surface structure of language v. deep structure of language Propose innate language acquisition device used to explain why all cultures languages and learning is so similar
16
B.F. Skinner Behaviorist Said it was operant conditioning learning and reinforcement
17
Concept =a way of grouping or classifying the world around us Typicality=the degree to which an object fits the average Prototype=typical picture that we envision
18
Superordinate concept=very broad; encompasses a large group of items Ex. Food Subordinate concept=smaller and more specific Ex. Bread
19
Cognition=thinking Reasoning=drawing of conclusions from evidence Deductive reasoning=drawing logical conclusions from general statements Inductive reasoning=the process of drawing general inferences from specific observations
20
Creativity and Problem Solving Creativity=the process of producing something novel yet worthwhile Divergent thinking if many correct answers are possible Ex. Brainstorming Convergent problem can only be solved by one answer
21
Heuristics=intuitive rules of thumb Algorithms=systematic, mechanical approaches that guarantee an eventual answer to a problem Insight=sudden understanding Ex. Wolfgang Kohler and chimps. Bananas outside cage, 2 sticks inside Mental set=fixed frame of mind Functional fixedness=tendency to assume that a given item is only useful for the task for which it was designed
22
Confirmation bias=looking only for information to support your view Hindsight bias=after the fact, saying you knew what the outcome would be Framing=the way a question is phrased
