This study examined the modifying effect of communication via voice or text on a cellular phone as it relates to the effects of feedback on future performance, self-efficacy, and perceived face validity. Previous literature has established an effect of positive feedback enhancing future performance and self-efficacy, and negative feedback decreasing future performance and self-efficacy, but no research currently exists on how this effect can be modified by method of delivery over cellular phone. This study examined the effect of positive and negative feedback by having participants complete self-efficacy, face validity, and performance measures. The participants then received positive or negative feedback via voice or text message on their cellular phones, and then completed a second set of measures. The results of this study did not find the expected base effect of positive and negative feedback, and showed that the forms used by participants had significantly different results. However, using a method to center scores, it was found that receiving feedback by voice significantly increased future performance when feedback was positive, and decreased when feedback was negative, in comparison to receiving the feedback by text. Future research should seek to further validate the results of this study by replicating the findings using equivalent forms. It should also look at demographic factors in relation to this study's findings.
