This chapter addresses the key principles of sport, exercise, and performance psychology. It reflects the broadening of sport psychology studies to encompass more widespread human performance research. The topic of decision making has been covered in psychology, economics, and motor learning but addressed very sparsely in sport, exercise, and performance psychology. Rational decision making requires defining the problem, identifying criteria, weighing those criteria, generating alternative solutions, and ultimately computing the optimal decision. The chapter introduces the literature on decision making and provides examples of factors that influence the choices people make. The decision to act, move, or what move to make is decided in the response selection stage, and the final stage is when one’s brain and muscles are organized to make the actual move. The key to improve the decision-making over time is to increase personal awareness of own limitations and keep learning and collecting information from reliable sources.

The primary purpose of Module 3 of the MAC program is the understanding and exploration of values as a central orienting concept. In the context of understanding the important role of values in enhanced performance and quality of life, the functional and dysfunctional role of emotions is also considered. This chapter suggests to clients that their personal values will be the anchor point for all behavioral decisions that need to be made in the course of enhancing performance and achieving goals. The concepts of mindful awareness, mindful attention, and cognitive fusion and cognitive defusion become integrated with the concept of values-directed versus emotion-directed behavior. The Relevant Mindful Activity Exercise is intended to connect the mindfulness concept to a relevant performance situation in the client’s life. The question of personal values is particularly salient when confronted by the variety of emotions and internal rules that client confronts on a daily basis.

This chapter presents a case study on performance dysfunction in the case of a 21-year-old African American female basketball player entering her senior year at a major Division I-level university. She described regret about not working out harder during the off-season, which she blamed for a poor start to her current season. In addition, she also reported feeling a great deal of worry over the possibility that she may have a poor season and ruin her chance to be drafted in the first round of the WNBA entry draft. According to the case formulation model, there are 10 elements that are necessary to consider prior to making an intervention decision contextual performance demands; skill level; situational demands; transitional and developmental issues; psychological characteristics/performance and nonperformance schemas; attentional focus; cognitive responses; affective responses; behavioral responses; and readiness for change and level of reactance.

Coverage of obesity in the popular press has reached a fever pitch in recent years. By far, the most common definition of obesity uses the body mass index (BMI) to determine who is overweight or obese. A person's BMI is a ratio of his or her weight to height. Many times BMI is criticized for the false positives, where very muscular people are deemed to be obese despite ultralow body fat levels. Waist circumference or waist-to-hip ratio (WHR) measures something called “abdominal or central obesity”, a condition that is closely related to negative health outcomes such as cardiovascular disease. The costs to society of obesity and related health issues are tremendous. Women, ethnic and racial subgroups, and those of low socioeconomic status (SES) all display higher rates of obesity than the overall population. Obesity is much more common in certain racial and ethnic subpopulations, as compared with Caucasian Americans.

This chapter presents the theoretical and empirical rationale for the development of an innovative intervention for the enhancement of performance. The mindfulness-acceptance-commitment (MAC) approach to performance enhancement is based on an integration of mindfulness and acceptance-based approaches and is specifically tailored for high-performing clientele. The predominant psychological approaches have emphasized the development of self-control of internal states such as thoughts, emotions, and physical sensations and have been commonly referred to as psychological skills training (PST) procedures. The self-regulatory PST procedures most often discussed are goal-setting, imagery/mental rehearsal, arousal control, self-talk modification, and precompetitive routines. The efficacy of psychological skills training techniques and procedures for performance enhancement has been most carefully evaluated within the context of athletic performance enhancement. Mindfulness can be seen as the process that promotes greater awareness of internal experiences and the defusion of one’s thoughts, emotions, and bodily sensations.

This chapter and the intervention protocol that follows seek to better understand and ultimately influence human performance through understanding how internal processes interact with external demands. Many factors determine the effectiveness of human performance. The myriad of factors contributing to functional as well as dysfunctional human performance can be summarized as follows: instrumental competencies, environmental stimuli and performance demands, dispositional characteristics, and behavioral self-regulation. The chapter presents the model of functional and dysfunctional human performance that involves three broad yet interactive phases, namely performance phase, postperformance response, and competitive performance. The professional literature in both clinical and cognitive psychology suggests that individuals develop an interactive pattern of self and other mental schemas. The accumulated empirical evidence has led to similar findings in studies across many forms of human performance. Chronic performance dysfunction is much more likely to be associated with an avoidant coping style.

This chapter describes a systematic approach to intervention planning in performance psychology. It presents a case formulation method for a comprehensive understanding of the client, and an appropriate multilevel classification system for sport psychology (MCS-SP) classification that subsequently either guides the proper delivery of the mindfulness-acceptance-commitment (MAC) program or leads to the determination that the performer’s needs are beyond the scope of the MAC program. The MCS-SP categorizes the issues and barriers facing the performer into four classifications: performance development (PD), performance dysfunction (Pdy), performance impairment (PI), and performance termination (PT). In the case formulation method suggested in the chapter, the practitioner’s first goal is to conceptualize performance needs and barriers based on the information systematically collected during the assessment process.

Beginning with Module 5 of the mindfulness-acceptance-commitment (MAC) protocol, this chapter seeks to enhance the client’s commitment to attaining performance-related values through the activation of specific values-directed behaviors. In this portion of MAC, the intent is to help clients distinguish between goals and values and explicate specific behaviors that will optimize what really matters to them in their individual performance domain. The chapter reviews the role that emotion plays as a barrier against necessary performance behaviors and, conversely, the concept of poise as a necessary ingredient in optimal performance. It identifies specific behaviors that, if engaged in regularly and consistently, are likely to result in enhanced performance. In Module 5, the consultant continues to help the client move ever closer to mindful engagement in competition by focusing more heavily on mindfulness practice.
