“…Neurophysiological reasons for the yips have been postulated based on its physical manifestation and observed cocontractions, which are similar to those of task-specific focal dystonias (Adler, Crews, Hentz, Smith, & Caviness, 2005;Adler et al, 2011;McDaniel et al, 1989;Sachdev, 1992) such as writer's cramp (Hermsdörfer, Marquardt, Schneider, Fürholzer, & Baur, 2011) or musician's cramp (Altenmueller & Jabusch, 2009). Psychological reasons have been suggested based on the symptoms worsening under stress (Masters & Maxwell, 2008), and the yips has been discussed as a chronic and severe form of choking under pressure (Bawden & Maynard, 2001;Klämpfl, Lobinger, & Raab, 2013a, 2013b) -a drop in performance caused by a perceived mismatch of situational demands and the athlete's own resources to master the situation (Hill, Hanton, Matthews, & Fleming, 2010). A neurophysiological-psychological interaction has also received support (Adler et al, 2005;Smith et al, 2000;Stinear et al, 2006) and is described in the continuum model of Smith et al (2003), placing the origin of the yips between purely neurological and purely psychological.…”
