The limited strength model of self-regulation posits that self-control strength is depleted when people regulate their thoughts, impulses, emotions, and behaviours. Research shows depletion of self-control strength in one task domain (e.g., controlling thoughts or images) leads to poorer self-control within similar and dissimilar domains (e.g., controlling physical endurance). The purpose of the present study was to investigate the aftereffects of performing mental imagery on two self-control tasks, physical endurance and response inhibition. Sedentary undergraduates (N = 37) were randomly assigned to either an imagery condition (n = 15), attention-placebo condition (n = 13), or a quiet rest control (n = 9). Participants performed two isometric endurance tasks (30% of maximum handgrip squeeze) separated by their respective study manipulation, and followed by the Wisconsin Card Sort Test (WCST). It was expected that participants in the mental imagery condition would show greater decrements in performance on the second endurance trial (when compared to baseline) and more perseverative errors on the WCST compared to the control conditions. All of the participants’ endurance performances declined over time (p < .05), however, no between group differences were found on endurance performances (p > .05) or on WCST scores (p > .05). Performing a basic 6 minute imagery session involving moderately-intense aerobic exercise does not appear to deplete self-control resources when compared to the attention-placebo and quiet rest control groups. However, the unanticipated decline in the endurance performances observed within the control conditions suggests that future research is needed to better understand the relationship between mental imagery and self-control depletion effects.","PeriodicalId":39479,"journal":{"name":"Journal of Imagery Research in Sport and Physical Activity","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2012-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/1932-0191.1074","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66798989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While much research has been conducted on the MG-A, MG-M, MS, and CS imagery functions, there has not been as much focus on CG imagery. This is somewhat disheartening since various researchers have pointed out this issue many times (e.g., Hall, 2001). The purpose of this review was to examine the research conducted on CG imagery since the publication of Martin and colleagues’ (1999) applied model of imagery use. A literature search was conducted of published peer-reviewed journal articles using Proquest to identify all studies that have examined CG imagery. Forty-three articles were identified as relevant towards understanding the role of CG imagery in sport. The research findings were discussed in one of two sections depending on the type of study design used (e.g., descriptive/correlational study or imagery intervention). The strengths and weaknesses of the CG imagery studies are discussed. From this review, the authors hope to make researchers aware of the avenues that still need to be explored in regards to CG imagery, as well as provide researchers with potential approaches to answer such questions.","PeriodicalId":39479,"journal":{"name":"Journal of Imagery Research in Sport and Physical Activity","volume":"186 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2012-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/1932-0191.1075","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66798752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data were drawn from 17 persons participating in a RCT investigating the effects of perspective use during MP on post-stroke recovery. The Vividness of Movement Imagery Questionnaire-2 (VMIQ-2) and a self-report perspective rating scale were used to examine changes in vividness and perspective maintenance, respectively. Findings indicate improvements in vividness were most evident in those with the weakest initial ability. Perspective maintenance improved significantly from the first score to the last for all groups. Visual imagery vividness was strongly related to kinesthetic imagery regardless of imagery perspective.

Aligned with the Applied Model of Mental Imagery, this study examined the cognitive and motivational functions of imagery used by 59 certified ATs and 34 AT students (N = 93, 19-48 years of age). Participants completed the Sport Imagery Questionnaire modified for the population. Image function and direction were also considered. Imagery training was only reported by 23% of the participants but 50% reported encouraging their athletes to use imagery and 86% believed the skill enhances their duties. Internal consistencies of the five image content subscales ranged from .83 to .68 and inter-scale correlations ranged from .72 to .76. ATs reported using MG-Mastery most frequently followed by CS-Skills CG-Strategies MG-Arousal and MS-Goals. Independent t-tests indicated MG-Goals was used more by students than certified ATs, t(91)=2.04, p<.05, and by non-practicing ATs than those who practiced, t(91)=-4.01, p<.001. Participants from curriculum programs reported more use of MG-Arousal than those from internship programs, t(91)=2.23, p=.05 and there was no gender variation across subscales. A trend of significant, negative correlations between education and the three motivation functions of imagery indicated the more educated ATs used imagery less for controlling emotions, mastering skills and setting goals. However, overall, the most frequently cited reason for using individual images was for confidence, followed by anxiety, goals, and skills and strategies. The majority of images were perceived to help job performance while one CG-Strategies and 4/5 MG-Arousal items were perceived as harmful to performance. Enhancing AT curricula with systematic training in psychological skills would enhance AT performance and disseminate information to clients.","PeriodicalId":39479,"journal":{"name":"Journal of Imagery Research in Sport and Physical Activity","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2011-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2202/1932-0191.1064","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68732626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to this proposition, the default imagery perspective is an internal 1st person perspective. However, few imagery inventories have been designed to differentiate and accurately measure these imagery perspectives (see Morris, Spittle, & Watt, 2005). Fewer still have considered athletic populations, in particular adolescent cohorts. Consequently, the current research examined the use of internal visual imagery (IVI), external visual imagery (EVI), and kinesthetic imagery (KI) amongst adolescent sport performers and whether the amount of hours engaged in practice outside of competition influenced their adoption. Eighty-seven (36 male, 51 female) county level participants from sports academies in the United Kingdom (M age = 14.0, SD = 1.92), from 6 interactive sports, completed the Vividness of Movement Imagery Questionnaire-2 (VMIQ-2; Roberts et al., 2008). Participants were grouped relative to the amount of practice they had engaged in since playing their current sport competitively. A repeated measures ANOVA recorded significant differences amongst participants vividness of imagery, Wilkes’ Λ F (2, 85) = 3.166, p < 0.05, η² = .07, post hoc pairwise comparisons using a Bonferroni adjustment revealed no significant differences between sub-scales. Results to MANOVA recorded no significant differences between VMIQ-2 sub-scales and three accumulated practice groupings, Wilkes’ Λ F (3, 82) = 436.14, p > 0.32, η² = .04. The results demonstrate adolescent sport performers possess between clear and reasonably vivid to moderately clear and vivid imagery ability when using IVI, EVI, and KI. Future research should consider the impact of environmental factors that influence the development of these modalities and perspectives.","PeriodicalId":39479,"journal":{"name":"Journal of Imagery Research in Sport and Physical Activity","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2202/1932-0191.1048","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68732307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Healing imagery has been found to effectively reduce the recovery time from various athletic injuries when combined with other mental skills such as self-talk and relaxation (Ievleva & Orlick, 1991). However, the literature remains void of a study that examines the potential benefits of the regular use of healing imagery techniques alone. This study compared the effects that a healing imagery intervention had on the recovery of one group of injured athletes to the recovery of a control group of injured athletes who did not receive the imagery manipulation. This study compared the two groups in three areas: satisfaction with rehabilitation, self-efficacy to recover, and return to play. The sample consisted of 9 injured varsity athletes (intervention group n = 5, control group n = 4). A significant interaction effect was found for satisfaction with rehabilitation, as athletes in the intervention group increased in satisfaction from Week 2 to Week 3, while the control group decreased in satisfaction during the same period. Both groups were found to be significantly higher in task self-efficacy than in coping self-efficacy during injury rehabilitation. The groups did not significantly differ in their return to play times. A qualitative review of the intervention group revealed that these participants believed that imagery helped them increase confidence, motivation, injury awareness, rehab adherence, relaxation, and focus, while decreasing their frustration with the rehabilitation program. This article discusses the results with respect to imagery effects, study limitations, and future directions.","PeriodicalId":39479,"journal":{"name":"Journal of Imagery Research in Sport and Physical Activity","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2011-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2202/1932-0191.1060","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68732544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
