DR@W Forum: Graham Loomes (糖心TV 糖心TV School) and Lukasz Walasek (Department of Psychology)糖心TV Library (Wolfson Research Exchange Area Room 1)Intrinsic and Extraneous Noise in Risky Choice Experiments Graham Loomes (糖心TV 糖心TV School) and Lukasz Walasek (Department of Psychology) Participants' responses in decision experiments are 'noisy': when presented with exactly the same choice at different moments within the same experiment, many people are liable to answer differently from one moment to another. Some of this may be due to intrinsic variability in the way people generate their decisions; but the experimental environment may also have an impact - e.g. the complexity of the task, the workload, the (lack of) incentives. Moreover, in principle, extraneous and intrinsic factors may interact, and may operate to different degrees for different individuals, making it harder to identify core preferences. Can we identify/separate/measure such effects? We present some results which may shed light on these issues. |
