Previous research has demonstrated that ostracism (to be excluded and ignored) leads to detrimental effects on four human needs (belonging, control, self-esteem, and meaningful existence; Williams, 2001). These detrimental effects, however, may be more pronounced, or more prolonged, in particular individuals (see Williams & Zadro, 2001). In the present study, we examined the persistence of the detrimental effects of ostracism in high and low socially anxious participants. The results show that being ostracized affected both groups at the immediate test, and that the high socially anxious participants recovered their primary needs more slowly. The results also show that being ostracized affects personality/attractiveness ratings of sources of ostracism, and increases the likelihood of interpreting ambiguous situations in a threatening manner. Overall, the study illustrates that a comprehensive understanding of ostracism, and the effects of moderating factors such as social anxiety, requires assessing the effects across time rather than only focusing on immediate reactions.
