psyc judgement Flashcards
learn
which two ways of evaluating judgement
correspondence theory,
coherence theory
who found the two theory’s of evaluation
hammond 2000
correspondence theory
weather judgement responds to the world
did the weather forecaster get it right
coherence
was forming of judgement rational
e.g logic
what is the social judgement theory
- probabilistic functioning
- tells the difference between environmental, cues and judges evaluation of cues
what does the social judgement theory assume
that people see the world as not direct but through interpretation of information cues
what is LHS
relationship between cue value and criterion to be judged
what is RHS
model of how someone uses cues to make judgements
what is the ecological validity of a cue
correlation between cue value and criterion or judgement
example for SJT
orquin 2014
Orquin 2014
lens model for consumers of packaged food
- compaired objective nutrition value (LHS) and expert judgement (RHS)
objective nutritional measure WXYfm score
how is SJT applied
gether data from experts, cues used and their weight
satisticle model and expert wightings
use statisticle model outpreforms human jusgement
what is the goldburg rule ?
finding difference between psychosis and neurosis
what scale did goldburg use
MMPI
goldburg mathmatics
add score from 3 scales and subtract from 2 scales
<45 diognose neurosis if not psychosis
results of goldburg rule
predicted 70% of new cases
experts using all scales predicted between 50 and 67&
multiple linear regression
relationship between dependent variable ad explanatory/ independent variables
difference between one and two IV
one = simple linear
two= MLR
what is the predictive model
Ye= dependent variable in evironment about judgement
X1- Xn = cues being used to predict DV
Be = weights for each cue
B0=constant term in equasion
E= remaining error not accounted for by modle
Results of regression analysis
200 records from airplane times, advert speed and band attractive rating
all were significance predictors in record sales
attractiveness in band was best predictor
what is the right hand side of model called
bootstrap
what is the model
Ys = dependent variable about judgement
Bs = subjective weights for the cues
what is more consistent for the model
bootstrap models as they out preform the individuals being more consistent
why are the models superiour?
more consistent due to historical data
people may reley irrelevent data
people focus on special cases not general info
influenced by recent info people effected by bordum
