Question 1

What DVs can in principle be predicted by iCodes?

Answer 1

Information search
choices
reaction times (for search & choices)
confidence judgements (for search & choices)

Question 2

What is the Attraction Search effect?

Answer 2

people are more likely to search for more information on the most attractive option

Question 3

How do you measure the attraction search effect?

Answer 3

Attraction Search Score
ASS = p(Searching for option A|Option A attractive) - p(Searching for Option A|Option A unattractive)
experiment where Option A & B, attractiveness of option A manipulated
[-1;1] negative -> inconsistent with Attraction search effect

Question 4

What is a conceptual (vs. a direct replication)?

Answer 4

Conceptual: the core idea stays the same but certain things are different from the original study e.g. other samples, materials
direct replication: everything is the same

Question 5

Why are conceptual replications important?

Answer 5

test for generalizability of the initial results, avoid possible confounds
external validity

Question 6

What is the predicted effect of the attractiveness-ratings manipulation before information search on 1) the bahavioral level, 2) the model-parameter level

Answer 6

1) more search for attractive option
2) gamma larger

Question 7

How does iCodes predict information search times & what two factors influence this prediction?

Answer 7

through predicting number of iterations until search decision
validities & coherence
validity: compulsatory (small differences) vs. non-compulsatory
