The aversive impact depends not only on the dollar value of the previous expense, but also on the timing and format of the expense. Soman (2001) argues that payment mechanisms in which the consumer can mentally rehearse the amount paid (e.g., a check where he is required to write the final amount, or a cash transaction in which the right amount has to be counted and change accepted) have a greater impact than payment mechanisms involving no rehearsal (e.g., a credit card payment where the consumer simply signs a receipt). Further, Soman (2001) also showed that the impact was lower for what he called “in process payments,” which he defined as situations in which “an expense had been incurred but the consumer’s wealth had not yet been depleted” (p. 462). And finally, Gourville and Soman’s (1998) results show that the aversive impact of payment depreciates as more time elapses from the time of payment.
