The current paper explores how people's goal strivings are influenced by feedback (positively valenced vs. negatively valenced), progress monitoring (remaining vs. accumulated) and goal specificity (vague vs. specific). Two laboratory-based experiments were performed. Experiment 1 reveals that, after receiving positively valenced feedback, participants who focus on accumulated progress show larger boosts in persistence than participants who focus on remaining progress. In contrast, after receiving negatively valenced feedback, participants who focus on remaining progress show larger boosts in persistence than participants who focus on accumulated progress. Experiment 2 extends the scope of the paper from understanding the effects of progress monitoring on goal striving to the effects goal specificity on goal striving. Experiment 2 shows that after receiving negatively valenced feedback, participants asked to consider specific goals (and so likely focus on remaining progress) show more persistence than participants asked to consider vague goals (and so likely focus on accumulated progress). These findings have important implications for motivation theory and applied practice. Keywords Motivation . Goal striving . Feedback . Goals . Behavior change Psychological theories of motivation largely fall within two categories: goal theories and attitude theories (Sloman 1996;Webb and Sheeran 2006). While motivation often unfolds in stages, with attitudes preceding goal formation, goal and attitude theories make conflicting predictions about the effects of feedback valence on goal striving. We propose that this conflict can be explained, at least in part, by an interaction between the type of feedback people receive and the type of progress monitoring they use.The current paper has two sections. Section 1, including Experiment 1, examines the relationship between feedback * Ivo Vlaev
