Security priming also facilitates effective provision of care and support to needy others. In two experiments, Mikulincer, Gillath, et al. (2001) and Mikulincer et al. (2003) found that subliminal priming with names of security providers, as compared with neutral priming, increased empathic concern for a suffering stranger and endorsement of prosocial values (concern for close others and for all of humanity). In another experimental study, we (Mikulincer, Shaver, Gillath, & Nitzberg, 2005, Study 1) examined the effects of security priming on the decision to help or not help a person in distress. Participants watched a confederate while she performed a series of aversive tasks. As the study progressed, the confederate became increasingly distressed, and the participant was given an opportunity to take her place, in effect sacrificing self for the welfare of another. Shortly before being exposed to the person's distress, participants were subliminally primed with either the name of a security provider (security priming) or a neutral name (neutral priming). We found that security priming, as compared with neutral priming, increased participants' compassion and willingness to take the distressed person's place. This effect occurred in both Israel and the United States, and occurred not only with subliminal primes but also when the priming was done supraliminally by asking participants to think of a familiar security provider (Mikulincer et al., 2005, Study 2).
