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

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

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)

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

A

-lets us know that certain concepts are related in a particular way, with some being general and others specific

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.

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

Q

Reasoning

A
  • the process of drawing inferences or conclusion from principles and evidence
  • 2 types of reasoning: deductive and inductive

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

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)

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

Q

Critical thinking

A
  • ability to analyze facts, generate and organize ideas, defend opinions, make comparisons, draw inferences, evaluate arguments, and solve problems
  • must be objective and skeptical in solving problems
  • requires evaluation of evidence and arguments independently of one’ prior beliefs and opinions
  • critical thinking allows use to counter assert action that have little basis in reality, and know the difference between sound and faulty reasoning
  • requires that we be open to evidence that bears on whether our ideas are correct or not, even if we are not happy with the evidence
17
Q

Scientific thinking

A
  • involves cognitive skills required to generate, test, and revise theories
  • what we believe and theorize about the world and what the world actually is, in the form of evidence, are two different things
  • scientific thinking keeps these two things separate
18
Q

Metacognitive thinking

A
  • requires the ability first to think and then to reflect on ones own thinking.
  • able to question their own thinking
19
Q

Heuristics

A
  • mental shortcuts we use to make decisions
  • methods for making complex and uncertain decisions and judgements
  • 2 types: representative heuristic and availability heuristic
20
Q

Representative heuristic

A
  • a strategy used to estimate the probability of one event based on how typical or representative it is of a another event.
  • eg. Concluding that joe could be a real estate agent based on knowing that he is friendly, often works weekends, and knows his way around town very well.
21
Q

Availability heuristic

A
  • a strategy we use when we make decisions based on the ease with which estimates come to mind or how available they are to our awareness
  • eg. When people make judgements about the aggressiveness of dog breeds.
  • vividness and availability lead us to overestimate how likely certain events are
22
Q

Rational choice theory

A
  • given a choice between 2 options, humans will choose the one that is most likely to help them achieve their particular goals
  • based on principles of behaviourism
23
Q

Cost-benefit analysis

A

-ask: do the costs outweigh the benefits?
-if yes, we dont buy
If no, we do buy
-however this usually isn’t the case

24
Q

Evidence against rational choice theory

A
  • not all reasoning is rational (eg. Confirmation bias)
  • if people were rational they would realize that the odds of 2 events can never be higher than the odds of one of those events alone
    • sometimes we get information that can be so representative of a stereotype that it biases us and we are likely to forget this rule
  • leads to conjunction fallacy
  • people also ignore base rates, biased by stereotypes etc
25
Q

Conjunction Fallacy

A
  • occurs when people say the combination of 2 events is more likely than either event alone
  • example with Linda being a bank teller and feminist.
  • example of a representative heuristic
