Key decision-makers among experts in a given field can sometimes be identified based on their role and responsibilities. The aim of the study is to compare perceptual-cognitive skills of experts with decisional responsibilities (setters in volleyball) with that of other volleyball experts. Eighty-two participants (26 setters, 36 other players and 20 controls) viewed 50 volleyball video sequences. Sequences stopped 120 ms before ball contact and participants, whose eye movements were recorded, had to predict the ball direction. Generalized Estimating Equations analysis revealed that setters and controls made more but shorter fixations than other players. However, both expert groups made better predictions than controls. Dynamics analyses of eye movements over time show that, right before ball contact, opposing players’ upper body is a most relevant attentional cue in all game situations. Results are discussed in terms of decision-making responsibilities to identify key decision-makers in volleyball and in general. They point towards specific perceptual-cognitive abilities found in setters and support the idea that they constitute a subgroup of experts, but that they are not “better” than other players in anticipating the game.

The first scientific papers on sport psychology consultants (SPCs) focused primarily on the professional practice of experienced SPCs. Since then, the scientific literature on SPCs has greatly diversified. The purpose of this review is to summarize and critically examine the findings of three scientifically studied topics on SPCs: SPCs' experiences, perceptions toward SPCs, and SPCs' effectiveness. Peer-reviewed scientific articles published in English were found in the main sport and psychology databases. The primary results in relation to each topic and the limitations of these papers are presented. The discussion examines future avenues from which to develop research on SPCs. Since Norman Triplett's first publication on the social facilitation of cyclists in 1897, the scientific study of sport psychology has greatly diversified. One aspect that has emerged from this field focuses on sport psychology consultants (SPCs) and their work. There are two main definitions of SPCs in the scientific literature. They can be seen as complementary because one focuses on the training requirements to become a SPC and the other on their role in applied sport psychology. Morris, Alfermann, Litunen, and Hall (2003) defined a SPC as a person trained in both psychology and sport science. Donohue et al. (2004) as well as Wrisberg, Simpson, Loberg, Withycombe, and Reed (2009) defined a SPC rather as a person who, during sport psychology consultations, supports athletes and coaches (stakeholders 1) in their development of mental and emotional skills with the aim to achieve optimal performance and improved well-being. A SPC might therefore be defined as a person who is trained in both psychology and sport and exercise science and who provides psychological support to stakeholders involved in sport. Note that, in addition to the term SPC, different terms in the
