Filter Theory (Broadbent, 1958)
We filter out information on the basis of physical characteristics. Filtering occurs very early, right after stimuli have been registered by our senses, and before any higher level perceptual processing has taken place

(Craik & Tulving, 1975)

(Gigerenzer & Gaissmaier, 2011) .- Heuristics
Heuristics are efficient cognitive processes, conscious or unconscious, that ignore part of the information
47 of 78
Availability Heuristic
People estimate the likelihood or frequency by the ease with which examples can be brought to mind.

1990’s Schwarz
List 6 instances in which you have behaved assertively How assertive are you on a scale of 1-5 (1 = not assertive at all, 5 = extremely assertive)? If you were asked to give 12 instances do you think your judgement would have changed? And how?

(Kahneman & Tversky, 1973)

Used a random spinner wheel between 0 and 100. On each Q the wheel was spun and ** asked first whether the answer was above or below where the wheel had stopped. Then gave their actual estimate to the Q

they are actually useful.

Gigerenzer & Gaissmaier (2011) offer a more ecologically valid explanation of decision making in the real world
Most situations do not give us information such as base rates, so making judgements based on representativeness is sensible.

What is reasoning?
Reasoning is a form of thinking. Understanding of reasoning has been strongly influenced by what we know about formal logic.
64 of 78
Form of logical reasoning?
if _____, then ___’. Logic provides a set of rules to determine if an inference is logically valid.
65 of 78
What components of deductive reasoning are there?

71 of 78
Marcus & Rips (1979)
The MP form is obvious and most people readily (typically nearly 100%) make it when content is sensible. However MT is not as intuitively obvious so most find this inference much harder (50% do not make this valid inference)
72 of 78
Wason Selection Task (1968) Aim?
Do people apply logic by falsifying and confirming it. Turn over cards to confirm a rule.

Example WST (1968)
Beer and Age.
74 of 78
WST (1968) Results
1 in 4 got it right. Context helps.
75 of 78
Mental logic theories Rips 1994
People use formal rules of inference but people do not possess all possible rules. This means that some inferences will be more difficult.
76 of 78
Mental Model Theory
People are capable of logical reasoning in principle. Mental model constructed and conclusions generated.uses working memory
77 of 78
Probabilistic approach Oaksford & Chater, 2003
The degree to which inferences are endorsed depends on the appropriate conditional probability.
