Previous literature has suggested an apparent P300 sensitivity to self-relevant stimuli. To further explore this relationship, we asked participants to submit 10 photos, each of a particular category (e.g. footwear, plants), to be used as either targets or distractors in a given condition of an oddball task. Furthermore, we attempted to see whether the effect of self-relevance on the P300 could be induced in a participant by allowing them to study a set of unique photos which would then be used as targets. Our analysis suggested that P300 amplitude elicited in response to self-relevant stimuli used as targets was statistically significantly greater than all other conditions’ targets. This effect was not correlated with the participant sentiment toward their own photos as assessed by the Revised Personal Involvement Inventory. In light of this, we suggest a generalized effect of self-relevance on the P300. Limitations and future directions are discussed.
