Children growing up in poverty have more uncertain surroundings, where less inhibition and better switching enables them to better take advantage of opportunities. Hypothesis 1 predicted that childhood scarcity would be positively related to cognitive switching, but only when participants were tested while in a scarcity mind-set. Hypothesis 2 predicted that childhood scarcity would be negatively related to inhibition, but again only while participants had a scarcity mind-set. Previous studies that applied the sensitized-specialized hypothesis to the relationship between childhood scarcity and adult executive functioning found inconsistent results. A reproduction study with different methods was therefore performed to see whether these methods would find clear effects of childhood scarcity. Participants were induced into a scarcity mind-set by letting them recall a moment of perceived financial scarcity. Switching was measured with the Number-Letter task, while inhibition was measured with an anti-saccade task. No support was found for Hypothesis 1, while partial support was found for Hypothesis 2. It is advised to perform more research in an ecologically valid environment.Show less
