Experiential Phase: Trial Structure for Receivers.
(a) On Shocks for you: Chance trials participants were informed that the outcomes would only be relevant to them and did not involve the other participant. The computer then selected an allocation of shocks at random. The participant received the stated number of shocks and was then asked to rate the intensity of the shocks on a visual analogue scale. We subsequently elicited participants’ willingness to pay to avoid three further repeats of the same outcome (not shown in this figure). (b) Split Shocks: Chance trials proceeded in the same manner, though in this case the computer ‘randomly’ chose how to allocate 24 shocks between the two participants. (c) The trial structure was identical in Split Shocks: Partner Decides trials, though on these trials the Receiver was informed that an allocation chosen by their partner would be selected and played for real.
