An experiment was conducted to contrast cognitive and motivational explanations of why a decision maker integrates a prior outcome with the expected outcomes of a current choice. Undergraduate students imagined that, on a fictitious day at a racetrack, they did not gamble in the prior race, that they gambled and won, or that they gambled and lost. Subjects rated in one session the likelihood of choosing to gamble in the current race. In another session, they rated how satisfied they would be with not gambling, with gambling and winning, and with gambling and losing, respectively. In support of a concreteness principle based on the assumption that cognitive effort is minimised, the results showed more integration of the prior outcome for descriptions of the bets which concretely integrated the prior outcomes with all the outcomes of the current choice than for descriptions which did not do that. A motivational explanation labelled the ''loss-sensitivity principle'' was also empirically supported in that, irrespective of concreteness of the descriptions, the prior outcome was always integrated with the expected loss of the current choice.
