ecological rationality & adaptive heuristics Flashcards
ecological rationality
dms have more than one decision strategy resulting from past experience and training
weighted additive rule
alternative have an overall value calculated based on the weight by the attribute value for each attribute
calculate weights, all must sum to 1
eqw
equal weight heuristic
assumes all attributes can be expressed on common value scale
satisficing
aspiration level and then compares each alternative to that level
first that passes aspiration level on all the attributes is selected
lexicographic
most important attribute and compares alternatives on that attribute
elimination by aspects
cutoff value adopted and all alternatives that are below the cutoff on that attribute are eliminated
majority of confirming dimensions
compare alternatives on dimensions in pairs and select the one with majority fo higher values
frequency of good and bad features
based on simple conts of good and bad
ecological rationality fits between H and current environment
h judged by match between h and new environment
- should i b applying this here
modularity
domain specific, innately specified, informationally encapsulated
-aggregate together to perform
adaptive heuristics
fast and frugal
FFH: take the best
cues in order to discriminate
FFH: recognition
choose which ever is recognised
recognised has higher value
german city
FFH: minimalist
examine cues until one matches aspiration level
search principles, stopping rule, decision rules
CRITIQUE: H&B ecologically rational
not irrational!
