Non-instrumental information and decisions under risk

Further information is available at GitHub (<b>https://github.com/julian-matthews/information-availability-risk</b>)<br><br>Here we provide R code and complete trial-by-trial data supporting our study of non-instrumental information availability and risky decision-making. <br><br>Code description<b>exp1_stats.R</b>: statistics for Experiment 1<b>exp2_stats.R</b>: statistics for Experiment 2<b>exp3_stats.R</b>: statistics for Experiment 3<b>group_stats.R</b>: pooled statistics including data from all experiments<b>information-model-comparison.R</b>: model comparison and boostrap simulations<br><b>Data description</b>Behavioural data<b>exp_version</b>: the experiment in our study; EXP1, EXP2, or EXP3<b>subject_num</b>: the unique ID for each of 71 participant across out experiments<b>trial_num</b>: the trial number from 1 to 180information: non-instrumental information availability, reflected in the number of slots with veridical information from 0 to 5<b>stake</b>: the amount of money that can be won or lost on the trial. Fixed at 50 cents for EXP1. Varies from 10 to 50 cents (in 10 cent increments) for EXP2 and EXP3.<b>decision</b>: whether the gamble was accepted (1) or rejected (0). Coded (NA) if no response was made within the 5 second response window.reaction_time: the amount of time it took to make a decision<b>outcome</b>: the predetermined outcome of the gamble (if the participants chooses to accept)<b>early_late</b>: in EXP3 only, whether information was available at the earliest or latest opportunity (analysed for information levels 1:4)<br>Modeling data<b>exp_version</b>: as above<b>subject_num</b>: as above<b>trial_num</b>: as above<b>information</b>: as above<b>decision</b>: as above<b>mod2_linear</b>: information value in model 2<b>mod3_entropy</b>: information value in model 3<b>mod4_res_uncertainty</b>: information value in model 4
