Participants completed four stock market games where they allocated their (hypothetical) wealth between investing in a share vs. the bank. The bank paid a steady, risk-free, interest while money invested in the share could increase or decrease depending on its behaviour. Anticipatory Skin Conductance Response (aSCR) was measured in a critical time period. Participants also completed the Positive and Negative Affect Scale (PANAS). There were 30 participants, recruited in and around the University of Bath, U.K.
