“…In the self-talk literature, the use of manipulation checks has been considered crucial to protect the integrity of the experimental conditions From the lab to field: Effects of self-talk on task performance under distracting conditions by Galanis, E., Hatzigeorgiadis, A., Comoutos, N., Charachousi, F., & Sanchez, X. The Sport Psychologist © 2017 Human Kinetics, Inc. (Hardy, Hall, Gibbs, & Greenslade, 2005). In studies where detailed manipulation checks have been used, participants have been excluded for either reporting the use of strategic self-talk while in a control condition (Hatzigeorgiadis et al, 2008), reporting not using self-talk while in an experimental condition (Hatzigeorgiadis, Zourbanos, Mpoumpaki, & Theodorakis, 2009), or reporting some other type of strategic self-talk, rather than the one instructed (Hardy, Begley, & Blanchfield, 2015). In accordance to this practice, control participants using self-talk systematically were excluded to prevent the integrity of the experimental manipulation; yet results including all participants were also presented to provide a full description of the data.…”
