Background:
This study took place at the height of the fifth wave of COVID-19 in France, coinciding with stigmatizing communication toward the unvaccinated. We hypothesized that adherence to this communication would facilitate or inhibit the effects of priming on vaccination intention, depending on whether the priming included a dimension of connection to others.
Participants And Procedure:
In a convenience online French sample (N = 1800, M age = 26.30), vaccination intention was asked after love priming, no love/prejudice priming, materialism priming, or a control condition. Participants also reported their adherence to restrictive measures, i.e., media control, vaccination pass, and mandatory vaccination.
Results:
Vaccination intention was higher in the no love/prejudice and materialism conditions than in the love and control conditions. Adherence to restrictive measures mediated the effect of prejudice or materialism priming on intention to get vaccinated.
Conclusions:
Implications of these results are discussed in light of the socially situated cognition perspective and the congruence of (a) a societal context of communication toward the vaccine and the unvaccinated, (b) the participant's degree of adherence to that communication, (c) the theme of priming, whether or not related to feeling connected to others. Implications of materialism priming are discussed, and the effect of commitment on intention to get vaccinated.
