Decision Making Under Uncertainty Human Subjects Data - Fire Evacuation Task

Total Size: 79 MB

This dataset contains de-identified data from human subjects experiments, along with the images and code that were used to run the experiments (as a crowdsourced online study). In this study, participants were shown the probability of a house being in the burn zone of a wildfire. They were asked if they would stay in the house or evacuate in that scenario. The probability information was presented in different ways, including text and maps. The studies tested the impact of different visual cues on the participants' patterns of decisions.

Transfer data using Globus

Fields

Item = Item number

WorkerID = Participant identifier

List = Experiment counterbalancing list

Final Bonus = Bonus payment earned by participant (in cents)

img = Image shown

Outcome = Scenario outcome (safe or burn)

CorrAns = corrent answer (stay or evacuate)

Resp = Participant's response

Acc = Participant accuracy

RT = Response time (in milliseconds)

Order = Order in which scenario was presented for each participant

Encoding = Stimulus type

NumBands = Number of probability bands (specificity condition)

VisCond = Visualization condition

VisOrText = Visualization or text stimulus

RiskBand = Probability band in which house is located

BandNum = Distance of relevant probability band from the center

ActualProbofBurningDown = Underlying risk level used for stimulus development

RiskLevel = 1 = highest risk level, 9 = lowest risk level

Background = Background color

Subject = WorkerID (redundant with prior column)

Evac = Stay/evacuate decision converted to 0 for stay and 1 for evacuate
