= 2,362) that used different cognitive paradigms (e.g., visual search, conflict processing) and reward-related stimuli (e.g., money, attractive food). Overall, results showed that reward-related distractors impaired cognitive performance across different tasks and stimuli, with a small effect size (standardized mean change = .347). Between-study heterogeneity was large, suggesting that researchers can plausibly expect to sometimes find reversed effects (i.e., reward-related distractors boosting performance). We further showed that the average reward-driven distraction effect was robust across different reward-learning mechanisms, contexts, and methodological choices, and that this effect existed regardless of explicit task instructions to ignore distractors. In sum, the findings of this meta-analysis support the notion that cognitive processes can be thwarted by reward cues. We discuss these findings against the background of distraction-related phenomena as they are studied in clinical, educational, and work psychology.
