The purpose of this study was to evaluate the effects of cognitive specific and motivational general-mastery imagery on self-efficacy for discrete and continuous skills in 12-14 years old learners. Four soccer teams from soccer Academies were selected (age: 12.85±0.45 years). Comparing penalty and dribbling self-efficacy before and after eight weeks of cognitive specific imagery for dribble, cognitive specific imagery for penalty and motivational imagery general – mastery with control group, did not show a significant difference. Imagery instructions may be age appropriate. The use of mental imagery in the 12-14 years participants should be used with caution and under the supervision of expert Sport Psychologists. https://biomedpharmajournal.org/vol7no2/the-effect-of-imagery-type-on-self-efficacy-for-discrete-and-continuous-soccer-skills/ Cognitive specific imagery Motivational general-mastery imagery Soccer Self-efficacy
