Thinking And Reasoning (Ch 8) Flashcards
1
Q
Cognition
A
- means “to know”
- refers to mental processes involved in acquiring, processing and storing knowledge
2
Q
Cognitive psychology
A
-the science of how people think, learn, remember and perceive.
3
Q
Mental representations
A
- a structure in our mind - such as an idea or image - that stands for something else, such as the external object or thing.
- used to represent ideas, knowledge, or memories
- allows us to think about and remember things in the past or imagine things in the future, and abstract ideas (love, truth, justice)
- usually represent thoughts verbally and visually
4
Q
Visual representation
A
- visual system located in the occipital lobes is older than the verbal system
- only animals with significant cortex are able to keep and store visual sensations in mind after stimulation stops
- visual imagery: involves visual representation created by the brain after the original stimulus is gone
- brain is active in same way during visual imagery as visual perception
- priming the brain to imagine success actually helps us be successful
5
Q
Mental rotation
A
- process of imagining an object rotating in 3-d space
- boys and men generally do better than females
- gender identification may affect this difference
- levels of testosterone affect this ability (non-linear relationship)
6
Q
Verbal representation
A
-humans organize sensory experience by putting like with like and then distinguishing that group from other groups
7
Q
Concept
A
- most basic unit of knowledge
- mental grouping of objects, events, or people
- help us organize our perceptions of the world
- store and process concepts in a hierarchy or by parallel distributed processing
8
Q
Concept hierarchy
A
-lets us know that certain concepts are related in a particular way, with some being general and others specific
9
Q
Parallel Distributive Processing (PDP)
A
- associations between concepts activate many networks or nodes at the same time
- concepts are activated in the network based on how strongly associated or connected they are to eachother
- also arranged by similarity and hierarchy
- location of concept based on its relationship to other concepts
- relationship between nodes can be HAS, CAN, or IS A.
10
Q
Category
A
- a concept that organizes other concepts around what they all share in common
- can be concrete or abstract
- best fitting examples of category called prototype
11
Q
Prototypes
A
-the best fitting examples of a category
12
Q
Reasoning
A
- the process of drawing inferences or conclusion from principles and evidence
- 2 types of reasoning: deductive and inductive
13
Q
Deductive reasoning
A
- occurs when we reason from general statements of what is known to specific conclusion
- the specific conclusion is always correct of the general statement is true
14
Q
Inductive reasoning
A
- draws general conclusion from specific evidence
- such conclusions are less certain than those drawn from deductive reasoning because may different conclusions might be consistence with a specific fact
- scientists who develop theories employ inductive reasoning
- using indicative reasoning is often using causal inferences (judgements about whether one thing causes another)
15
Q
Confirmation bias
A
- the tendency to selectively attend to information that supports one’s general beliefs while ignoring information that contradicts one’s beliefs
- tested by Wason with number rule… students rarely tested against their hypothesis
- best way to test an idea is to try and tear it down but people rarely do this
