Does mental practice enhance performance

Mental practice is the cognitive rehearsal of a task prior to performance. Although most researchers contend that mental practice is an effective means of enhancing performance, a clear consensus is precluded because (a) mental practice is often denned so loosely as to include almost any type of mental preparation and (b) empirical results are inconclusive. A meta-analysis of the literature on mental practice was conducted to determine the effect of mental practice on performance and to identify conditions under which mental practice is most effective. Results indicated that mental practice has a positive and significant effect on performance, and the effectiveness of mental practice was moderated by the type of task, the retention interval between practice and performance, and the length or duration of the mental practice intervention. Mental practice refers to the cognitive rehearsal of a task in the absence of overt physical movement. When a musician practices a passage by thinking it through or when an athlete prepares for an event by visualizing the steps required to perform the task, he or she is engaging in mental practice. A number of studies have examined the effects of mental practice on performance. Whereas the research of Kelsey (1961) and Ryan and Simons (1982) supports the efficacy of mental practice for enhancing performance, Beasley (1978) reported negative results. An astute reviewer may be able to estimate the direction and magnitude of effect of the relationship between mental practice and performance from the preponderance of evidence across the majority of studies. For example, Richardson (1967a) concluded that most studies support the efficacy of mental practice on performance. However, Richardson, and later Corbin (1972), noted that this evidence was inconclusive. Because different studies use different types of tasks, with different types of subjects, and report different study statistics, it is difficult if not impossible to integrate these disparate research studies on an intuitive level to draw firm conclusions on the effectiveness of mental practice. The purpose of this study was to integrate the literature on mental practice, summarize the overall effects of mental practice on performance, and specify the conditions under which mental practice is most effective.

Imagining is not doing but involves specific motor commands: a review of experimental data related to motor inhibition

There is now compelling evidence that motor imagery (MI) and actual movement share common neural substrate. However, the question of how MI inhibits the transmission of motor commands into the efferent pathways in order to prevent any movement is largely unresolved. Similarly, little is known about the nature of the electromyographic activity that is apparent during MI. In addressing these gaps in the literature, the present paper argues that MI includes motor execution commands for muscle contractions which are blocked at some level of the motor system by inhibitory mechanisms. We first assemble data from neuroimaging studies that demonstrate that the neural networks mediating MI and motor performance are not totally overlapping, thereby highlighting potential differences between MI and actual motor execution. We then review MI data indicating the presence of subliminal muscular activity reflecting the intrinsic characteristics of the motor command as well as increased corticomotor excitability. The third section not only considers the inhibitory mechanisms involved during MI but also examines how the brain resolves the problem of issuing the motor command for action while supervising motor inhibition when people engage in voluntary movement during MI. The last part of the paper draws on imagery research in clinical contexts to suggest that some patients move while imagining an action, although they are not aware of such movements. In particular, experimental data from amputees as well as from patients with Parkinson’s disease are discussed. We also review recent studies based on comparing brain activity in tetraplegic patients with that from healthy matched controls that provide insights into inhibitory processes during MI. We conclude by arguing that based on available evidence, a multifactorial explanation of motor inhibition during MI is warranted.

Re-imagining motor imagery: Building bridges between cognitive neuroscience and sport psychology

One of the most remarkable capacities of the mind is its ability to simulate sensations, actions, and other types of experience. A mental simulation process that has attracted recent attention from cognitive neuroscientists and sport psychologists is motor imagery or the mental rehearsal of actions without engaging in the actual physical movements involved. Research on motor imagery is important in psychology because it provides an empirical window on consciousness and movement planning, rectifies a relative neglect of non-visual types of mental imagery, and has practical implications for skill learning and skilled performance in special populations (e.g., athletes, surgeons). Unfortunately, contemporary research on motor imagery is hampered by a variety of semantic, conceptual, and methodological issues that prevent cross-fertilization of ideas between cognitive neuroscience and sport psychology. In this paper, we review these issues, suggest how they can be resolved, and sketch some potentially fruitful new directions for inter-disciplinary research in motor imagery.

Measuring Motor Imagery Using Psychometric, Behavioral, and Psychophysiological Tools

This review examines the measurement of motor imagery (MI) processes. First, self-report measures of MI are evaluated. Next, mental chronometry measures are considered. Then, we explain how physiological indices of the autonomic nervous system can measure MI. Finally, we show how these indices may be combined to produce a measure of MI quality called the Motor Imagery Index.

Mental Practice: Effective Stress Management Training for Novice Surgeons

BACKGROUND Surgeons are often subject to excessive levels of acute stress that can impair their performance. Mental practice (MP) is a strategy used in other high-performance industries to alleviate anxiety. This study investigated if MP reduces stress in novice surgeons. STUDY DESIGN A prospective, randomized controlled design was used with 20 novice surgeons recruited by random sampling. After baseline testing, participants underwent training on an evidence-based virtual reality (VR) curriculum. They then performed 5 VR laparoscopic cholecystectomies (LC) after being randomized to MP or control groups. The MP group performed 30 minutes of MP using a validated MP training protocol before each LC; control participants conducted an unrelated activity. Stress was assessed subjectively using the validated State-Trait Anxiety-Inventory (STAI) questionnaire and objectively with a continuous heart rate (HR) monitor and salivary cortisol. Mental imagery was assessed using the validated mental imagery questionnaire. RESULTS Eighteen participants completed the study. There were no intergroup differences in baseline stress, imagery, or technical ability. Comparing the MP group with controls, subjective stress (STAI) was lower for the MP group (median 8.40 vs 11.31, p < 0.01). Objective stress was also significantly reduced for the MP group in terms of the average HR (median 72 vs 88 beats/minute, p < 0.0001), maximum HR (median 102 vs 119 beats/minute, p < 0.01), and cortisol (median 2.26 vs 3.85 nmol/L, p < 0.05). Significant negative correlations were obtained between stress and imagery, indicating that improved imagery was associated with lower stress (p < 0.05). CONCLUSIONS A short period of MP reduces the subjective, cardiovascular, and neuroendocrine response to stress on a VR simulator. Additional research should determine whether this effect extends beyond novice surgeons and transfers to the operating room.

What can Learning Styles Research Learn from Cognitive Psychology

Abstract People differ from each other in the manner in which they process information from the world. These individual differences are called learning styles’. The purpose of this paper is to explore how research in this field can benefit from certain findings in cognitive psychology. Following a review of some difficulties which afflict research on learning styles (e.g. inadequate construct validation of measures), attention is drawn to two relevant findings in cognitive research: the influence of prior knowledge on learning and the potential value to learners of ‘metacognitive’ awareness. Some implications of these findings for learning styles research are then discussed.

A Review of Single-Case Research in Sport Psychology 1997–2012: Research Trends and Future Directions

Single-case research methods are an important facet of applied sport psychology because they provide a framework for researchers and practitioners to outline intervention effects across time with individuals or groups. This paper reviews the research published since Hrycaiko and Martins (1996) milestone overview of single-case research in sport psychology. Specifically, we examined the literature between 1997 and 2012 and located 66 studies that met our inclusion criteria of assessing interventions in sport psychology. The review summarizes the body of research, outlines trends, considers the limitations of the extant literature, and identifies areas that require further investigation for future single-case research.

Functional equivalence or behavioural matching? A critical reflection on 15 years of research using the PETTLEP model of motor imagery

Motor imagery, or the mental rehearsal of actions in the absence of physical movement, is an increasingly popular construct in fields such as neuroscience, cognitive psychology and sport psychology. Unfortunately, few models of motor imagery have been postulated to date. Nevertheless, based on the hypothesis of functional equivalence between imagery, perception and motor execution, Holmes and Collins in 2001 developed the PETTLEP model of motor imagery in an effort to provide evidence-based guidelines for imagery practice in sport psychology. Given recent advances in theoretical understanding of functional equivalence, however, it is important to provide a contemporary critical reflection on motor imagery research conducted using this model. The present article addresses this objective. We begin by explaining the background to the development of the PETTLEP model. Next, we evaluate key issues and findings in PETTLEP-inspired research. Finally, we offer suggestions for, and new directions in, research in this field.

Flow Among Musicians: Measuring Peak Experiences of Student Performers

“Flow” is a highly coveted yet elusive state of mind that is characterized by complete absorption in the task at hand as well as by enhanced skilled performance. Unfortunately, because most measures of this construct have been developed in physical activity and sport settings, little is known about the applicability of flow scales to the experiences of performers in other domains such as music. To fill this gap in the research literature, the present study had two objectives. First, we investigated the psychometric adequacy of the Dispositional Flow Scale–2 (DFS-2) for a large sample (n = 205) of musicians. In addition, we examined the experience of flow among amateur and elite music students. Results indicated that the DFS-2 is a generally reliable and factorially-sound measure of flow and that flow states are experienced quite frequently by music students. Nevertheless, the results also raise questions about the validity of certain subscales of this test (e.g., merging of action and awareness, loss of self-consciousness). The theoretical and practical significance of these findings is discussed and suggestions are provided for future research on flow.

‘There’s more to an image than meets the eye’: A qualitative study of kinaesthetic imagery among elite canoe-slalomists

Kinaesthetic imagery involves feelings of force and motion or the mental simulation of sensations associated with bodily movements. Although this type of imagery is very important to athletes in many sports it has attracted little research attention from psychologists. Accordingly, the purpose of this paper is to investigate kinaesthetic imagery processes among a sample (n=12) of elite athletes - namely, World Cup competitors in canoe-slalom. These athletes (mean age = 25 years; SD=4.16) were first interviewed about their understanding and use of ‘feeling-oriented’ in their sport. Next, they were assessed using a battery of measures which included Likert rating scales and a standard test of mental imagery - the Movement Imagery Questionnaire-Revised (Hall & Martin, 1997). Finally, in an effort to validate their imagery experiences, athletes were timed as they engaged in a ‘mental travel’ procedure in which they had to visualise a recent race and execute it as if they were paddling physically. The time tak...
