The present study investigates self-reinforcing spirals processes between the negative affect toward asylum seekers and the attention to political advertising in a campaign dealing with the issue of the asylum law restriction. Based on data from a three-wave panel survey, the study found evidence of such reciprocal influences. Specifically, the initial attention to political advertising elicited negative affective reactions, such as fear or anxiety toward asylum seekers in the course of the campaign. At the same time, these affective reactions enhanced people’s attention to subsequent political ads. Not only do the findings indicate the presence of reinforcing spirals processes but also do the data suggest that the spirals process is mainly fueled by cues emanating from the political campaign.
