“…This may be especially pertinent in soccer where the outcome of the match has large financial implications (Hoffmann, Ging, & Ramasamy, 2002). The term "momentum" is frequently used to describe where the sequence of scoring or winning (success) has an influence on future performance success (Briki, Den Hartigh, Markman, Micallef, & Gernigon, 2013;Gernigon, Briki, & Eykens, 2010;Iso-Ahola & Dotson, 2014;Taylor & Demick, 1994;Vallerand, Colavecchio, & Pelletier, 1988). In contrast, "psychological momentum" (PM) is a term used in sport psychology that captures not only the success -future performance relationship, but also shifts in affect, cognition and behaviour in either a positive or negative direction in athletes, coaches and fans (Jones & Harwood, 2008;Markman & Guenther, 2007;Perreault et al, 1998;Taylor & Demick, 1994;Vallerand et al, 1988).…”
