An explanation for the variables in the raw data
The data includes the following variables:
SubjID, Location, Gender, Age, set, Condition, GameID, Ha, pHa, La, Hb, pHb, Lb, Manipulation, Amb, LotShape, LotNum, Corr, Order, Trial, Button, Risk, Payoff, Forgone, RiskPay, Feedback, block
SubjID = the subject serial no. in the lab
Location = whether the study was conducted at the Technion (“Technion”) or at the Herbew U. of Jerusalem (“Rehovot”)
Gender = subject's gender, M for Male, F for Female
Age = the subject's age
Set = the set of problems the subject played. Set1 includes problems 1-30 (study1), set2 includes problems 31-60 (study2) and set3 includes problems 61-90 (study2)
condition = ByProb refers to the condition in which subjects played by problems (25 trials in each), ByFB is the condition where subjects played the 5 trials without feedback for the 30 problems, and then played the other 20 trials for each problem
GameID = serial number of the choice problem. See note at the bottom of this page.
Ha = high payoff from option A
pHa = probability of getting Ha
La = low payoff from option A
Hb = high payoff from option B
pHb = probability of getting Hb
Lb = low payoff from option B
Manipulation = the framing of the choice problem (see section “space of problems” in the paper).“Abstract” framing is presentation of payoffs and their probabilities, “StPb” is a St. Petersburg type of presentation, and AcRj is accept/reject type of presentation.
Amb = Ambiguity parameter. if Amb is 0 then probabilities of Option B are described, if Amb is 1 then these probabilities are not described
LotShape = the shape of the outcome lottery distribution (Option B) in each problem. See Appendix A in the paper for details.
LotNum = indicates the number of possible outcomes of Option B in each problem. Problems with LotNum>1 are multi outcome problems. See Appendix A in the paper for details.
Corr = the correlation between the payoffs. Can be 0, 1, or -1
Order = the order in which the choice problem appeared in the set
Trial = the number of trial in which the choice was made (there are 25 trials per choice problem)
Button = R if the subject selected the button positioned on the right side of the screen, and L if the left button was chosen
Risk = whether the subject “took risk”, gets 0 if Option A was chosen and 1 if Option B was chosen.
Payoff = the outcome from the chosen option in each trial
Forgone = the outcome of the unchosen (forgone) option in each trial
RiskPay = the outcome of the risky option (B) in each trial (regardless of choice)
Feedback = Feedback is 0 if the trial does not include feedback information (trials 1-5), and 1 if there is feedback information (trials 6-25).
Block = 5 blocks of 5 trials each. Block 1 is the first 5 trials with no feedback, all other blocks include feedback
