Extending Knowledge of the Effects of Social Influence in Warning Compliance

<jats:p> Three experiments are reported which measure the effects of social influence on participants' willingness to use protective equipment when carrying out a paint-spraying task within a laboratory setting. The first study established baseline compliance levels in both low-cost and high-cost conditions. The second study showed that compliance levels are greater when a single confederate also uses the protective equipment, and lower when the confederate does not use the equipment. The third study shows that a larger group of confederates, where only the majority comply or do not comply, can also influence participant compliance in the same way. </jats:p>
