Internal and External Imagery Perspective Measurement and Use in Imagining Open and Closed Sports Skills: An Exploratory Study

01 Apr 2007-Perceptual and Motor Skills (Ammons Scientific Ltd.)-Vol. 104, Iss: 2, pp 387-404
TL;DR: Analysis indicated that the questionnaire gave a general imagery perspective preference but was not a strong predictor of imagery used on specific occasions, and the three measures of imagery perspective were equivalent in imagining performing particular skills.
Abstract: This study explored the measurement and use of internal and external imagery perspectives during imagery of open and closed sports skills. Participants (N=41; male=23; female = 18), ages 14 to 28 (M=19.4 yr.; sD=3.1), who were recruited from undergraduate classes in human movement and physical education, and local sporting teams, completed the Imagery Use Questionnaire and then imagined performing eight common sports skills, four open skills and four closed skills, in a random order. Participants provided concurrent verbalisation during their imagery. Immediately after imagining each skill, participants completed a rating scale and retrospective verbalisation of imagery perspective use. Analysis indicated that the questionnaire gave a general imagery perspective preference but was not a strong predictor of imagery used on specific occasions. The three measures of imagery perspective were equivalent in imagining performing particular skills. Participants experienced more internal imagery than external imagery while imagining the eight sports skills, but there was no significant difference between perspective use on the open and closed skills.

Summary (4 min read)

Imagery Perspective Measurement and Open and Closed Sports Skills 3

  • Research has shown that imagery is an effective performance enhancement tool and is one of the psychological skills that sports psychologists and athletes use most (Murphy & Martin, 2002; Morris, Spittle, & Perry, 2004; Morris, Spittle, & Watt, 2005) .
  • Internal imagery involves the person imagining being inside their body and experiencing those sensations that might occur while performing in the real situation.

Measurement of Imagery Perspective Use

  • The development of appropriate measures of imagery perspective has been limited, consequently the measurement of imagery perspective use has been problematic, with many studies simply assigning participants to perspective training groups and assuming that they used the assigned perspective, or assigning participants to groups based on self-reported preferences.
  • The correlations between the CV, RV, and RS were all above .9, indicating a large effect size and a very high level of agreement between the three state measurement techniques.
  • The only comments consistently made were that CV seemed to slightly slow down the imagery process, but that it did not change how participants imaged.
  • To measure imagery perspective accurately, the results of this exploratory study suggest that a specific state measure, e.g., CV, RS, or RV, is more appropriate than a general questionnaire.
  • Thus, there has been a Imagery Perspective Measurement and Open and Closed Sports Skills 16 problem with ensuring the success of independent variable manipulation in the imagery literature.

Imagery Perspective Measurement and Open and Closed Sports Skills 4

  • There have been two main types of measure of imagery perspective use (Morris, et al., 2005) .
  • Trait measures use words like "usually", "generally", or "typically", because they are not focusing on specific events requiring temporal orientation or limitation, e.g., the Imagery Use Questionnaire (IUQ; Hall, Rodgers, & Barr, 1990) .
  • Retrospective reports are subject to memory lapses as well as spontaneous reconstruction of events or processes based on known outcomes (Anderson, 1981; Brewer, Van Raalte, Linder, & Van Raalte, 1991) .
  • Thus, a concurrent technique may provide a viable option for measuring imagery perspective use during imagery by providing an account of cognitive processing at the time it occurs, rather than retrospectively (Morris, et al., 2005) .

Imagery Perspective Use

  • Most research on imagery perspectives has focused on the influence of perspective on an outcome variable, such as performance, rather than focusing on which perspective participants use.
  • Some researchers have reported that the performance of different types of tasks was affected differently by the perspectives, with external imagery producing greater gains on one task and internal imagery on another (e.g., White & Hardy, 1995; Glisky, Williams, & Kihlstrom, 1996; Hardy & Callow, 1999) , but these have not investigated perspective use.
  • In imagery of the eight sports skills, participants also reported using more internal imagery than Imagery Perspective Measurement and Open and Closed Sports Skills 17 external imagery.
  • This also seems to coincide with the child development literature on perspective-taking, which suggests that the ability to take on the observer's perspective is not something the authors are born with, but needs to be developed (Epley, et al., 2004; Piaget, 1959; Rigal, 1996) .
  • Participants reported use of external imagery on the IUQ and during imagery trials, so external imagery, although not the default, may add something new and different to the imagery experience (Cox, 2002 : Morris, et al., 2004) or add to the useful information that is otherwise available (Hardy, 1997) .

Skill Type and Imagery Perspective Use

  • Several psychologists (Harris, 1986; McLean & Richardson, 1994; Annett, 1995) have suggested that closed skills might benefit more from internal imagery, whereas open skills might benefit most from external imagery.
  • For that reason, this exploratory study had two major aims.
  • The second major aim was to examine patterns of internal and external imagery perspective use during imagery of a variety of sports skills.
  • This pattern of use does not seem to support the suggestion of several researchers (e.g., Harris, 1986; McLean & Richardson, 1994) , who have proposed that learning and performance of closed skills would benefit more from an internal perspective, whereas open skills should benefit from an external perspective.

Participants

  • This exploratory study involved 23 male participants and 18 female participants with sporting experience, aged between 14 and 28, with a mean age of 19.4 years (SD = 3.12).
  • Participants were recruited from undergraduate classes in human movement and physical education, and local sporting teams.
  • Eleven participants reported they played cricket, six played netball, five played basketball, three played Australian Rules Football, three were rowers, two were swimmers, and two were triathletes.
  • There was one participant in each of the following activities: calisthenics, surfing, baseball, judo, soccer, running, recreation, 400 m running, and Australian Football League (AFL) umpiring.

Measures

  • Concurrent Verbalisation (CV) -This describes the process where individuals verbalise the information they are attending to and their conscious cognitive processes at the time when they are consciously attending to a process.
  • Instructions for CV, given before imagery, emphasised describing everything experienced while performing the imagery, with special emphasis on reporting whether the participants experienced the imagery from inside or outside the body.
  • The CV was recorded on audiotape and transcribed later.
  • Two independent raters scored the transcripts from CV for percentage of internal and external imagery.

Imagery Task

  • Participants were required to imagine performing eight sports skills.
  • Four of these skills were classified as open skills and four were classified as closed skills.
  • Instructions for imagery of these skills emphasised creating as realistic an imagery experience as possible, describing the use of different sense modalities and the experience of emotions.
  • Instructions were not provided that would encourage the use of either imagery perspective.
  • The open skills participants imagined were hitting a tennis ball back over the net, defending against an attack in a team ball game, catching a ball thrown when not knowing to which side it would be thrown, and dodging a ball unexpectedly thrown at the person.

Procedure

  • Participants were recruited from undergraduate classes in sports psychology and local sporting teams.
  • After providing informed consent, participants completed the IUQ to assess typical use of imagery perspective.
  • Participants imagined for two trials on each of four open and four closed skills.
  • During imagery of the skills, CV was recorded.
  • Finally, participants answered a series of debriefing questions.

Data Analysis

  • Pearson product moment correlation co-efficients were calculated among the imagery perspective measures (IUQ, CV, RS, and RV) to determine the similarity of Imagery Perspective Measurement and Open and Closed Sports Skills 12 these measures for assessing perspective use.
  • Then an independent samples t-test was conducted on the IUQ imagery perspective items to assess general reported imagery perspective use.
  • Descriptive statistics were compared on CV, RS and RV for internal and external imagery use during the imagery of the sports skills to assess actual imagery use on imagery trials and differences between imagery perspective use on the individual sports skills.
  • Finally, analysis of variance was conducted on scores on the CV, RS, and RV to determine any differences between perspective use for all the open skills compared to all the closed skills.

Concurrent Verbalisation (CV), Retrospective Verbalisation (RV), and Rating

  • Scores from CV, RV, and RS, averaged for the two trials for each skill are summarised in Table 2 .
  • The scores for the RS are also presented in Figure 1 to highlight the variation between scores on individual skills.
  • Possible scores range from 0 to 100, with a low score indicating more internal imagery and a high score indicating more external imagery.
  • Results indicated that, for every skill, participants experienced more internal imagery than external imagery.
  • The sports skills with the lowest scores, indicating the most internal imagery content, were hitting a tennis ball back over the net and catching a ball thrown at you when not knowing to which side it would be thrown.

This indicates variability between the responses of different participants for the same

  • Imagery Perspective Measurement and Open and Closed Sports Skills 14 skill, probably due to participants reporting either high internal or high external imagery content, with few rating moderate amounts of internal and external imagery for each skill.
  • The means for the four open and the four closed skills were both below 50, indicating that participants experienced more internal imagery than external imagery in both skill types.

Discussion

  • The perspective adopted during imagery affects the imagery experience and may mediate the relationship between imagery and learning or performance effects (Morris, et al., 2005) .
  • The measurement of imagery perspective use in the past has been limited to sporadic use of retrospective approaches, with limited development of appropriate tools.
  • In this exploratory study the measurement of internal and external imagery perspective use was investigated with several state and trait measurement approaches to assist in the development of appropriate imagery perspective measures.
  • To aid in the development of knowledge related to the role of imagery perspectives in imagination of sports skills, patterns of internal and external imagery perspective Imagery Perspective Measurement and Open and Closed Sports Skills 15 use during imagery of a variety of sports skills were also examined.
  • A range of open and closed skills were compared, based on the hypothesis that the type of task, open or closed, might affect imagery perspective use (e.g., Harris & Robinson, 1986; McLean & Richardson, 1994; Morris, et al., 2005) .

Methodological Issues

  • In the present study, a higher use of internal imagery overall was found.
  • The study does not provide information on which perspective is more effective for performance enhancement of these skills.
  • Thus, research is needed to investigate internal and external training effects on performance.
  • If participants were given more descriptive detail of the event and also the event was made more realistic or of a longer duration, then imagery perspective use patterns may differ.

Summary. - This study explored the measurement and use of internal and
external imagery perspectives during imagery of open and closed sports skills.
Participants (n=41; male = 23; female = 18), ages 14 to 28 (M = 19.4 years; SD =
3.12), who were recruited from undergraduate classes in human movement and
physical education, and local sporting teams, completed the Imagery Use
Questionnaire (IUQ; Hall, Rodgers, & Barr, 1990) and then imagined performing
eight common sports skills, four open skills and four closed skills, in a random order.
Participants provided concurrent verbalisation (CV) during their imagery.
Immediately after imagining each skill, participants completed a rating scale (RS)
and retrospective verbalisation (RV) of imagery perspective use. Results indicated
that the IUQ gave a general imagery perspective preference, but was not a strong
predictor of imagery used on specific occasions. The CV, RS, and RV were
equivalent measures of imagery perspective used to imagine performing particular
skills. Participants experienced more internal imagery than external imagery while
imagining the eight sports skills, but there was no significant difference between
perspective use on the open and closed skills.

Imagery is a process where an individual recalls or creates sensory
experiences in the absence of external stimuli usually associated with these
experiences (Murphy, 1994). Research has shown that imagery is an effective
performance enhancement tool and is one of the psychological skills that sports
psychologists and athletes use most (Murphy & Martin, 2002; Morris, Spittle, &
Perry, 2004; Morris, Spittle, & Watt, 2005). One variable that may affect the
effective use of imagery is the imagery perspective the individual adopts (Morris, et
al., 2005). Mahoney and Avener (1977) defined perspective in terms of whether the
image is internal or external. They proposed that external imagery occurs when the
person views themselves from the perspective of an external observer, much like
watching oneself on TV. Internal imagery involves the person imagining being inside
their body and experiencing those sensations that might occur while performing in
the real situation. If imagery perspective affects the effective use of imagery, then
investigating the use of imagery perspectives is imperative to understanding how to
use imagery effectively (Morris, et al., 2005). To examine imagery perspective, it is
important that imagery perspective use be measured appropriately. This study
examined the crucial issues of measurement of imagery perspective preferences and
imagery perspective use. In addition, because the type of skill or task being imagined
might affect imagery use, the influence of task type on imagery use was considered.
Measurement of Imagery Perspective Use
The development of appropriate measures of imagery perspective has been
limited, consequently the measurement of imagery perspective use has been
problematic, with many studies simply assigning participants to perspective training
groups and assuming that they used the assigned perspective, or assigning
participants to groups based on self-reported preferences.

There have been two main types of measure of imagery perspective use
(Morris, et al., 2005). First, preference or trait measures ask a person to make an
overall or global assessment of their usual perspective use, with the person not
oriented towards a specific previous event. Trait measures use words like “usually”,
“generally”, or “typically”, because they are not focusing on specific events requiring
temporal orientation or limitation, e.g., the Imagery Use Questionnaire (IUQ; Hall,
Rodgers, & Barr, 1990). Second, imagery perspective use has been assessed by
presenting a scene to imagine and, following imagery, asking people to rate their
imagery of that scene on a scale, e.g., the Movement Imagery Questionnaire (MIQ;
Hall, & Pongrac, 1983) and the Vividness of Movement Imagery Questionnaire
(VMIQ; Isaac, Marks, & Russell, 1986). These reports are retrospective in the sense
that they ask people to recall a specific event, which requires a temporal orientation.
Retrospective reports are subject to memory lapses as well as spontaneous
reconstruction of events or processes based on known outcomes (Anderson, 1981;
Brewer, Van Raalte, Linder, & Van Raalte, 1991). Thus, a concurrent technique may
provide a viable option for measuring imagery perspective use during imagery by
providing an account of cognitive processing at the time it occurs, rather than
retrospectively (Morris, et al., 2005). Concurrent Verbalisation (CV) is a process
where an individual verbalises their cognitive processes while performing the task. It
is “thinking aloud” (Ericsson & Simon, 1980). CV has been used successfully in the
study of mental processes, such as problem-solving (e.g., Newell & Simon, 1972),
visual and verbal coding (e.g., Schuck & Leahy, 1966), cue-probability learning
(e.g., Brehmer, 1974), concept learning (e.g., Bower & King, 1967), mental
multiplication (e.g., Dansereau & Gregg, 1966), performance on intelligence tests
(e.g., Merz, 1969), concentration during running (Schomer, 1986), and expertise in

chess (DeGroot, 1965). Studies on imaginal activity in non sport situations have used
the CV technique (e.g., Bertini, Lewis, & Witkin, 1969; Kazdin, 1975, 1976, 1979;
Klinger, 1978; Klos & Singer, 1981; Petre & Blackwell, 1999). In a study of non
sport motor skills, Annett (1986) investigated imagery of everyday skills, such as
knot tying and forward rolls, with CV. Verbalisation can also be used retrospectively
to understand cognitive processes. Studies that have used a retrospective
verbalisation (RV) protocol include studies on concept learning (Hendrix, 1947;
Phelan, 1965), learned generalisations (Sowder, 1974), concept formation
(Rommetveit, 1960, 1965; Rommetveit & Kvale, 1965a, 1965b), and expert-novice
differences in tennis (McPherson, 2000). Despite their potential to provide rich
information on the content of imagery, neither CV nor RV has been used to explore
imagery perspective use.
Imagery Perspective Use
Most research on imagery perspectives has focused on the influence of
perspective on an outcome variable, such as performance, rather than focusing on
which perspective participants use. Questionnaire studies provide some insight into
imagery perspective use. In the questionnaire research on imagery perspectives,
researchers have typically employed a “trait” approach (Morris, et al., 2005). The
findings have been mixed, with some studies finding that elite or more successful
performers used more internal imagery than less elite/successful athletes (e.g.,
Mahoney & Avener, 1977; Doyle & Landers, 1980; Carpinter & Cratty, 1983; Barr
& Hall, 1992), some studies finding no difference between these categories of
performer (e.g., Highlen & Bennett, 1979; Meyers, Cooke, Cullen, & Liles, 1979;
Rotella, Gansneder, Ojala, & Billing, 1980; Hall, et al., 1990), or that elite athletes
used more external imagery (e.g., Ungerleider & Golding, 1991). Studies that have

TL;DR: Internal mental imagery has a greater effect on muscle strength than external mental imagery does, and the combination of mental imagery and physical practice is more efficient than, or at least comparable to, physical execution with respect to strength performance.
Abstract: The aims of the present review were to (i) provide a critical overview of the current literature on the effects of mental imagery on muscular strength in healthy participants and patients with immobilization of the upper extremity (i.e., hand) and anterior cruciate ligament (ACL), (ii) identify potential moderators and mediators of the "mental imagery-strength performance" relationship and (iii) determine the relative contribution of electromyography (EMG) and brain activities, neural and physiological adaptations in the mental imagery-strength performance relationship. This paper also discusses the theoretical and practical implications of the contemporary literature and suggests possible directions for future research. Overall, the results reveal that the combination of mental imagery and physical practice is more efficient than, or at least comparable to, physical execution with respect to strength performance. Imagery prevention intervention was also effective in reducing of strength loss after short-term muscle immobilization and ACL. The present review also indicates advantageous effects of internal imagery (range from 2.6 to 136.3%) for strength performance compared with external imagery (range from 4.8 to 23.2%). Typically, mental imagery with muscular activity was higher in active than passive muscles, and imagining "lifting a heavy object" resulted in more EMG activity compared with imagining "lifting a lighter object". Thus, in samples of students, novices, or youth male and female athletes, internal mental imagery has a greater effect on muscle strength than external mental imagery does. Imagery ability, motivation, and self-efficacy have been shown to be the variables mediating the effect of mental imagery on strength performance. Finally, the greater effects of internal imagery than those of external imagery could be explained in terms of neural adaptations, stronger brain activation, higher muscle excitation, greater somatic and sensorimotor activation and physiological responses such as blood pressure, heart rate, and respiration rate.

TL;DR: It is suggested that imagery perspective may not be an important variable in MP interventions, and MP combined with occupational therapy improves upper-extremity recovery after stroke.
Abstract: OBJECTIVE. This preliminary study sought to determine whether the imagery perspective used during mental practice (MP) differentially influenced performance outcomes after stroke. METHOD. Nineteen participants with unilateral subacute stroke (9 men and 10 women, ages 28–77) were randomly allocated to one of three groups. All groups received 30-min occupational therapy sessions 2×/wk for 6 wk. Experimental groups received MP training in functional tasks using either an internal or an external perspective; the control group received relaxation imagery training. Participants were pre- and posttested using the Fugl-Meyer Motor Assessment (FMA), the Jebsen–Taylor Test of Hand Function (JTTHF), and the Canadian Occupational Performance Measure (COPM). RESULTS. At posttest, the internal and external experimental groups showed statistically similar improvements on the FMA and JTTHF (p < .05). All groups improved on the COPM (p < .05). CONCLUSION. MP combined with occupational therapy improves upper-extremity recovery after stroke. MP does not appear to enhance self-perception of performance. This preliminary study suggests that imagery perspective may not be an important variable in MP interventions

TL;DR: Findings highlight differential efficacy of internal and external visual imagery for performance improvement on complex sport skills in early stage motor learning in young male novices.
Abstract: The purpose of this study was to determine the effects of internal and external visual imagery perspectives on performance accuracy of open and closed tennis skills (i.e., serve, forehand, and backhand) among novices. Thirty-six young male novices, aged 15-18 years, from a summer tennis program participated. Following initial skill acquisition (12 sessions), baseline assessments of imagery ability and imagery perspective preference were used to assign participants to one of three groups: internal imagery ( n = 12), external imagery ( n = 12), or a no-imagery (mental math exercise) control group ( n = 12). The experimental interventions of 15 minutes of mental imagery (internal or external) or mental math exercises followed by 15 minutes of physical practice were held three times a week for six weeks. The performance accuracy of the groups on the serve, forehand, and backhand strokes was measured at pre- and post-test using videotaping. Results showed significant increases in the performance accuracy of all three tennis strokes in all three groups, but serve accuracy in the internal imagery group and forehand accuracy in the external imagery group showed greater improvements, while backhand accuracy was similarly improved in all three groups. These findings highlight differential efficacy of internal and external visual imagery for performance improvement on complex sport skills in early stage motor learning.

TL;DR: A positive correlation was observed between the two questionnaires, supporting findings on the componential basis of imagery, and dancers and karatekas had higher mean scores on imagery ability than the non-athlete group.
Abstract: While imagery research has become popular in recent years, little research has specifically investigated differences in imagery ability between open- and closed-skill sport activities. The purpose of this study was to investigate whether the type of task, open or closed, affects vividness and controllability differently. Thirty female classic dancers (closed skill), 30 female karate athletes (open skill), and 30 female non-athlete students, between 14 and 20 years of age (M = 17.0, SD = 1.6), participated. They completed the Vividness of Visual Imagery Questionnaire, the Vividness of Movement Imagery Questionnaire, and the Subtraction of Parts Task. There was no difference in imagery ability between open- and closed-skill sport groups. Furthermore, dancers and karatekas had higher mean scores on imagery ability than the non-athlete group. A positive correlation was observed between the two questionnaires, supporting findings on the componential basis of imagery. This study contributed to increase the research in the specific area of open- and closed-skill sports and imagery ability.

TL;DR: In this article, the authors examined the use of imagery according to Paivio's (1985) general analytic framework and found that participants used more motivational general-mastery imagery than recreational level participants.
Abstract: This study examined the use of imagery according to Paivio's (1985) general analytic framework. The aims were to examine functional differences in imagery use according to the five subscales of the SIQ, to investigate differences in imagery use by competitive level, and to explore the influence on the use of imagery of skills involving a perceptual target (reactive tasks) and without a perceptual target (nonreactive tasks). Participants included 484 individuals (280 male, 204 female), with a mean age of 20.39 (SD = 4.10) from the United Kingdom, Finland, and Australia. The group comprised 84 national, 21 0 state, 120 district, and 70 recreational level athletes representing 54 sports. Participants completed a demographic information sheet and the Sport Imagery Questionnaire (SIQ). Participants were classified according tocompetitive level and task type. Results indicated that overall participants used more motivational general-mastery imagery. A one-way multivariate analysis of variance revealed that there were significant differences among the four competitive levels on imagery use with the district level participants reporting significantly higher use of motivational general-arousal (MG-A) imagery than state and national level participants and national level participants reporting higher use of cognitive specific (CS) imagery than recreational level participants. There was also a significant difference between tasks with a perceptual target and tasks with no target for motivational-specific imagery, with higher scores for tasks with a perceptual target. The results suggest the continued evaluation of imagery use in relation to competitive level and support that task type may influence the functional use of imagery in sport.

TL;DR: In this paper, the relative efficacy of different imagery perspectives on the performance of tasks in which form was important was examined, and it was found that external visual imagery was significantly more effective than internal visual imagery, which was also significantly more useful than stretching.
Abstract: Three experiments examined the relative efficacy of different imagery perspectives on the performance of tasks in which form was important. In Experiment 1,25 experienced karateists learned a new kata using either external or internal visual imagery or stretching. Results indicated that external visual imagery was significantly more effective than internal visual imagery, which was significantly more effective than stretching. In Experiment 2, 40 sport science students learned a simple gymnastics floor routine under one of four conditions: external or internal visual imagery with or without kinesthetic imagery. Results revealed a significant main effect for visual imagery perspective (external visual imagery was best) but no effect for kinesthetic imagery. Experiment 3 employed the same paradigm as Experiment 2 but with high-ability rock climbers performing difficult boulder problems. Results showed significant main effects for both visual imagery perspective (external visual imagery was best) and kinesth...

TL;DR: The use of imagery by athletes was assessed by administering a 37-item questionnaire to a sample of 381 male and female participants from six sports: football, ice hockey, soccer, squash, gymnastics, and figure skating as discussed by the authors.
Abstract: The use of imagery by athletes was assessed by administering a 37-item questionnaire to a sample of 381 male and female participants from six sports. The sample comprised competitors in the sports of football, ice hockey, soccer, squash, gymnastics, and figure skating. Athletes reported using imagery more in conjunction with competition than with practice. The motivational function of imagery was found to be important, but no substantial differences were evident between how athletes employ visual and kinesthetic imagery or how they use internal and external imagery perspectives. Athletes also indicated that they do not have very structured or regular imagery sessions. The level at which athletes were competing (recreational/house league, local competitive, provincial competitive, national/international competitive) was found to influence imagery use. The higher the competitive level, the more often the athletes reported using imagery in practice, in competition, and before an event.

TL;DR: The Imagery in Sport as discussed by the authors is a comprehensive overview of theoretical models, research, and practical applications of imagery in sport-related contexts, and includes extensive recommendations for implementing imagery training programs highlighting athlete characteristics, image content, rehearsal routines and ways to evaluate imagery-training programs.
Abstract: is a comprehensive overview of theoretical models, research, and practical applications of imagery in sport-related contexts. Not surprisingly, just about every study conducted on imagery in sport and motor performance is included in this book. These are used to highlight methodological paradigms, practical implication, and future research directions for inquiring minds. The reference-text approach to Imagery in Sport is facilitated by several tables enabling readers to compare and contrast extensive information. For example, major concepts of ten popular imagery theories are presented. Measurement tools are compared based on image modality, dimension, question style, number of items, and format. In addition, several models are utilized to illustrate research paradigms and specifi c imagery predictions. Aligned with ideas that imagery is an ability that improves with practice and that all athletes have the potential to expand the way they use imagery, practitioners will fi nd the four chapters devoted to imagery application informative. This section amalgamates applications from popular applied sport psychology textbook chapters that are limited in scope. Imagery in Sport includes extensive recommendations for implementing imagery training programs highlighting athlete characteristics, image content, rehearsal routines, and ways to evaluate imagery-training programs. Six popular imagery-training interventions are reviewed, including Visuomotor Behavioral Rehearsal (VMBR), the AIM strategy (Korn, 1994), guided imagery, and stress inoculation training. The applied examples and imagery scripts, albeit few, can be tailored to fi t client characteristics especially if practitioners pay close attention to Singerʼs (1988) fi ve step strategy intervention framework and key components of an imagery training program presented in chapter 8. For those interested in augmenting imagery with technological aids (a.k.a. techno-junkies), descriptions of video modeling, biofeedback, heart rate monitors, and fl otation devices will be fascinating. In another nifty table, the authors outline four imagery uses for rehabilitation contexts: healing, pain management, the process of rehabilitation, and performance-related imagery. Practitioners working in the allied health professions (e.g., physical therapists, athletic trainers) will benefi t from details about the imagery process and related outcomes, which can serve to assist in tailoring image content to specifi c rehabilitation goals. Although practicing sport psychologists are identifi ed as the target audience in the preface, Imagery in Sport will certainly appeal to inquiring minds including students and scholars embarking on related research or those who have taken a hiatus from the topic. A signifi cant portion of the layout is devoted to application

TL;DR: In this article, the effects of an imagery training program on imagery ability, imagery use, and figure skating performance were investigated, and the influence of imagery training on skating performance was compared to verbalization training.
Abstract: The effects of an imagery training program on imagery ability, imagery use, and figure skating performance were investigated. In addition, the influence of imagery training on skating performance was compared to verbalization training. The study employed two groups of figure skaters, an imagery training group, and a verbalization training group. All skaters were assessed for movement imagery ability, their use of imagery, and their skating performance prior to and following a 16-week training period. During this training period the imagery and verbal groups received instruction and guidance in the use of their respective types of mental practice. The imagery group improved in visual movement imagery ability and showed several changes in imagery use. Specifically, they were more likely to use imagery in practice, had more structured imagery practice sessions, and could more easily visualize and feel certain aspects of their skating performance compared to the verbalization group, In terms of perfo...
