Introduction: The purpose of the present study was to investigate the effect of strategic self-talk on the performance and visual attention of volleyball players.Methods: The current research was semi-experimental with a pre-test and post-test design with a control group. The participants of the present study were 54 boy volleyball players, who selected as available. The participants randomly divided into five groups: Strategic self-tlk as instructional self-talk (N=10), motivational self-talk (N=11), instructional-motivational self-talk (N=10), motivational-instructional self-talk (N=11) and control (N=12). The self-talk intervention conducted for 12 weeks and three sessions per week. In pre-test and post-test, while performing the serve task, the serve score were recorded by the researcher and the gaze behavior of the participants was measured by the eye tracker. The collected data were analyzed using analysis of covariance and Bonferroni's post hoc test.Results: The results of the study showed that strategic self-talk has a significant effect on serve performance (P=0.0001) and the quiet eye duration (P=0.0001). The results of the Bonferroni test showed that instructional self-talk increased motor performance and increased the duration of the quiet eye. In addition, the combined groups that have used this instruction have increased motor performance and a longer duration of quiet eye. However, motivational self-talk has no effect on motor performance and the duration of quiet eye.Conclusion: The results obtained in the current research emphasize the importance of instructional self-talk on the performance and visual attention of novice volleyball players and supports the attention mechanism of self-talk.

The aim of this study was to compare the effect of self-talk (ST), feedback (KP) and their interaction (STF) on acquisition and retention of basketball chest pass. 120 adolescent girls were selected and randomly assigned to 4 groups: KP, ST, ST + KP and control. This study was semi-experimental and pretest-posttest design with a control group. Instructional self-talk and knowledge of performance feedback were used in this study. After the pretest, each group had 4 practice sessions in the acquisition phase; then, they had posttest and 72 hours later they had retention test. One-way ANOVA and Tukey post hoc test were used to analyze data. Results indicated those subjects who used ST achieved better acquisition and retention scores than the other groups (P<0.05). ST was more effective than KP in the acquisition of chest pass skill. ST and KP can lead to a better and faster development of learning in the early phases

Aim: One of the issues that have been considered more than before is the issue of aging. An aging is a period that is accompanied by gradual, progressive and spontaneous erosion changes in most physiological devices and functions of the body. One of the widespread problems that occur in the aging process is the loss of balance, increased fluctuations and the risk of falling. Falling down is one of the most common and most serious problems are aging. For this reason, today, many researchers have drawn attention to the various ways in which elderly people develop their balance. Recently, some researchers have found that the use of cognitive strategies such as self-talk can improve the performance of motor tasks. Self-talk, essentially has two main instructional and motivational functions. Motivational self-talk through increased self-confidence and instructional self-talk by enhancing focus on techniques improve their sports performance and learning skills. On the one hand, it is important to increase the effectiveness of the instructions in order to focus on the focus. Wolfe's researches (1998-1992), given the constrained action hypothesis in most sports skills as well as balance skills, suggest that the use of external attention in comparison with internal attention during the skill leads to better performance and learning. Several studies have been conducted on motivational and instructional self-talk about different athletic skills and different skill levels that have led to a variety of outcomes, but few studies have considered the scope of balance. So, the aim of this study was to evaluate the effect of attentional focus types as the self-talk form on static and dynamic balance in elderly women using instructional self-talk focus strategy. Methodology: The present study was a quasi-experimental study with pre-test and post-test. The experimental group included instructional self-talk with internal focus and instructional self-talk with external attention as well as a control group. The population of the study consisted of all elderly women living in the nursing home in Qazvin who 45 people (66.75 ± 5.65 years) were selected according to the inclusion criteria. Inclusion criteria included Lack of movement restrictions, non-fracture in the lower extremities in the past year and the lack of use of neurological drugs. After the pre-test they were randomly assigned to groups. The control group without self-talk, self-talk group with internal focus and self-talk group with external focus practice their balance skills during the five sessions. At the end of the fifth session, the post- test was conducted using static balance (stork) and dynamic balance (timed up and go) tests. In the stork test, the subject must stand on top of his leg, lift the other leg and stick to the knee of the leg, and simultaneously place his hands on the iliac crest of the pelvis. The time that a person could stand open with his eyes was considered as an indicator of his static balance ability. Each subject performed the test three times and the highest time was recorded. The errors that caused the test to be stopped include lifting the hands from iliac crest of the pelvis, detaching the leg from the knee of the foot and any movement on the foot of the reliance.Each subject performed a three-time test of timed up and go, and his best time was recorded. Since the subject was announcing his stand, the timer began to work, and the timer stopped when it hit the subject back with chair. The self-talk group with the instruction of focus of the internal attention, repeated the words "knee and foot" before each loud performance, which meant "bending slightly knees and maintaining the balance on the foot", and the external attention group referred to the term "target and wall" Which meant "looking at the target mounted on the wall.Results: One-way ANOVA, mixed ANOVA and repeated measure ANOVA were used to analyze the data. Data was analyzed using SPSS software version 20. The significance level was considered 0.05. The results showed that both self-talk groups performed significantly better than the control group in static balance.Conclusion: However Self-talk interferences with both types of attentional focus; it was not a significant difference in the dynamic balance of elderly people (P≥0.05). Taking the results into consideration it can be concluded that, self-talk with internal and external focus instructions can be considered as a cognitive strategy to improve the static balance of elderly people.

The aim of the present study was to investigate the effect of different methods of self-talk (motivational, instructional, and combined) on acquisition and learning of a motor perceptional task (dart) and physical efficacy in female students aged between 13 and 18. 48 female students (mean age 15.46 yr) who were novice at dart throwing voluntarily participated in this study. Participants were divided into 4 groups including motivational self-talk, instructional self-talk, motivational-instructional self-talk and physical practice (12 students in each group) following an initial instructional session and pretest. The intervention included 10 sessions of acquisition, 2 sessions of retention test and one session of transfer test. One-way ANOVA and ANOVA with repeated measures were used to analyze data. Results showed that combined (motivational-instructional) and the instructional self-talk groups improved dart throwing performance in acquisition, immediate and delayed retention sessions in 13-18-year-old students compared with the motivational self-talk and physical exercise groups. Instructional self-talk group showed the best performance in transfer test while the other three groups showed almost similar performances. The results also showed that different interventions had no significant effects on physical self-efficacy of the participants.
