This thesis introduces and defines perceived self cost (PSC) as a new framework for understanding helping/prosocial behaviors. Following a literature review, two experiments are proposed to investigate this new construct. The first experiment would be a pilot study to validate the use of PSC as a construct. The second experiment would utilize brief vignettes that manipulate levels of PSC and empathy in an attempt to predict and measure whether empathy moderates the hypothesized effects of high PSC that may deter prosocial behavior. Implications for how PSC may shape prosocial decision making will be discussed.
