Dataset: Psychological Momentum in Football: The Impact of a Last-Minute Equalizer in a Knock-Out Match

In the current study, 86 competitive male players were asked to imagine that they were playing in a cup final in which they were trailing 1-0 or leading 1-0. Subsequently, participants watched a video clip in which their team or the opponent team scored the equalizer either in the 61st minute or 92nd minute (i.e., last-minute) of regular playing time. Participants indicated their PM after the equalizer. Results showed that PM was higher when players’ own team scored than when the opponent team did. Furthermore, the equalizer had a particularly big impact on PM when the goal was scored last-minute. The data set includes background information of the participants (soccer level, experience), as well as their responses on PM items after the equalizer.
