Very little research has investigated differences in imagery use between open-and closed-skill sports. The purpose of this study was to examine the influence of competitive level (elite/novice) and skill-type (open/closed) on athletes' imagery use. A total of 83 British athletes (39 elite, 44 novice) from open-(n = 40: 23 rugby; 17 martial arts) and closed-skill (n = 43: 28 golf; 15 figure skating) sports completed the Sport Imagery Questionnaire no more than 24 hours prior to competition. MANOVA revealed that main effects due to competitive level and skill-type were significant ( p < .05). Univariate analyses revealed that elite athletes used more CS and CG imagery than novices ( p < .001), and contrary to previous research findings, athletes in open-skilled sports used more MG-A imagery than those in closed-skill sports ( p < .001). Overall, MG-M was the most used imagery type, regardless of competitive level and skill-type. The results are discussed in terms of methodological difficulties, future research, and practical implications.Mental imagery has been recognized as an important tool in improving athletic performance (Hall, 2001). Many of the world's highest-level athletes report using imagery in the hope of improving their routines and they have attributed at least some of their success to mental imagery (Hardy, Jones, & Gould, 1996). Furthermore, Hardy et al. noted that imagining perfect executions of a particular skill might very well augment the activation of relevant motor programs needed for that particular skill. Paivio (1985) proposed an analytical framework describing the functions of imagery, through which the problem of when and why imagery works could be addressed. He suggested that mental imagery might influence behavior on a general or a specific level through both cognitive (e.g., skill and strategy rehearsal) and motivational (e.g., self-confidence, arousal, goal-setting) mechanisms. Drawing from Paivio's work and other existing literature on imagery, Hall, Mack, Paivio, and Hausenblas (1998) conducted a series of investigations and concluded that imagery serves five main functions: (a) cognitive specific (CS; e.g., specific sport skills), (b) cognitive general (CG; e.g., strategies related to a competitive event), (c) motivational specific (MS; e.g., specific goals and goal-oriented behavior), (d) motivational general-arousal
