This commentary addresses Allen, Fioratou, and McGeorge (2011), drawing attention to the important topic of how humans cognitively adapt to activities they engage in on a daily basis. We elaborate on the critique and suggestions made by Allen, et al. by reviewing research on the relationship of sport and cognition and argue that publication bias may be an issue when studying cognitive adaptations as a function of sport engagement. Implications for future research on the sport-cognition relationship are discussed.
