Maradona in our minds: Memory for the FIFA World Cup reveals common effects between individual and collective memories.
The FIFA World Cup football (soccer) tournament is one of the most widely watched sporting events in the world. Particularly, the Argentina national football team has appeared in five World Cup finals, winning two of them, and the general support for this team represents a long-standing tradition in this country. In the present study, we asked whether the history of the FIFA World Cup constructs a significant collective memory. Considering that this is an idiosyncratic and informal knowledge, largely affected by emotions, we hypothesized that it constitutes a solid ground for addressing collective memory properties. An online memory task was conducted asking to a large group of Argentine adults (N=407) which country was the winner, the runner-up, and the host of each FIFA World Cup tournament that took place since 1930 to 2014. In addition, participants were asked to rank the emotional content and the response confidence of each tournament. Finally, participants reported a number of keywords associated with each World Cup edition, to measure the memory detail. Overall, our results reveal the existence of a robust collective memory for the World Cup, showing a high memory accuracy and detail along the history of the championships. We demonstrated the presence of parallel effects between individual and collective memories, such as a serial-position effect, a modulation by emotion and a reminiscence bump. In addition, we modelled the forgetting curves for different World Cups, revealing that the most memorable ones where could take almost a century to fade from collective memory.
