'Pleasureful self-control'? A new perspective on old problems.

Many societal challenges, for example regarding health and sustainability, are conceptualized as problems of too little self-control: people's long-term goals are jeopardized (e.g., healthy weight, small carbon footprint) because one cannot resist attractive alternatives (e.g., chocolate cake, vacation in the sun). Here, we introduce a different way of conceptualizing those challenges, namely as problems of 'too little pleasure'. We review empirical evidence showing that pleasure can support three central aspects of self-control: the initiation of long-term goal behavior, persistence in long-term goal pursuit, and resisting tempting alternatives. We close by encouraging the field to change perspectives and to include pleasure in the solution of problems that have mainly been studied as a matter of too little self-control and too much pleasure.

Challenging the law of least effort.

Popular conceptions hold that effort is costly and aversive, causing people to generally avoid effort unless justified. We critically discuss evolutionary, phenomenological, and behavioral arguments supporting this "law of least effort", proposing that people may approach effort without direct extrinsic benefits. First, a "need for effort" is functional for health and learning. Second, experiencing contingency of effort and reward in the context of broader goals may lead to effort-seeking behavior. Moreover, beliefs with implications for the meaning of effort (e.g., as signaling difficulty or lack of talent) predict effort preferences. Thus, evolutionary, developmental, and social-cognitive factors may drive the pursuit of challenging goals that lie beyond life necessities but are essential for improvement and long-term development.

How to better promote teaching? Unveiling the links between Professional Learning Communities and Intrinsic Motivation among Foreign Language Teachers.

Professional Learning Communities (PLCs) assume a vital role in promoting teacher growth and development, while the presence of intrinsic motivation (IM) in the work environment profoundly impacts teacher performance. Unveiling the interconnections between teachers' engagement in PLCs and their intrinsic motivation holds the potential to enhance the overall well-being of both teachers and students. This study used a mixed-methods approach to investigate the relationship between PLCs and IM of Chinese Teachers of Foreign Languages (CTFL) in higher education. The questionnaire survey and semi-structured interviews were conducted among 198 teachers in 19 provinces of China. The quantitative data were analyzed by means of descriptive analysis and regression analyses with SPSS 22.0 and the qualitative data were processed by following thematic analysis. Results demonstrated that the participants' perceptions on their PLCs and IM were at a moderately high level, with mean scores at 3.56 and 3.86 on a 5-point Likert scale, respectively. Regression analyses revealed a significant positive correlation between PLCs and IM. Specifically, Shared Vision (SV), Supportive Environment (SE) and Collaborative Learning (CL) in PLCs were positively correlated with Willingness to Take on Challenges (WTC) and Love for Work (LW) in IM. The qualitative findings highlighted the significance of supportive environment and teacher's work engagement in affecting teacher's perceptions on PLCs. Job Characteristic of foreign language teacher, along with significant others might also influenced teachers' intrinsic motivation. Implications for PLCs leadership and foreign language teachers are discussed.

Gender and circadian preferences influence emotions and motivation in secondary mathematics classrooms.

Many studies have reported poor school achievement in evening persons and general circadian fluctuations in cognition. The aim of this study was to analyze circadian fluctuations in a cross-sectional design and examine the effects of chronotype on situational emotions and intrinsic motivation. A cross-sectional survey study was conducted in three Turkish secondary schools with a total sample of 599 students (283 females and 316 males). Data were collected at the end of specific math lessons of the same grade level and content, using a form combining three scales. We found no gender-related differences in intrinsic motivation, while there were some differences in situational motivation. In math classes, female students exhibited higher level of interest, while boys scored higher on boredom. In addition, students who scored high on morning affect reported higher levels of interest, well-being, and less boredom. Students with higher stability (and lower fluctuations in mood and cognition during the day) reported a higher degree of enjoyment, perceived competence, perceived choice, and less pressure/tension in their math lessons. A positive association was observed between distinctness, interest, and well-being, while negative correlations existed between distinctness and boredom. This suggests that students with higher diurnal stability reported a higher level of interest, well-being, and a lower level of boredom. Additionally, the results of the analyses showed that morningness, distinctness, and eveningness were significant predictors of intrinsic motivation. Conversely, gender, time of application, morningness, and distinctness emerged as predictors for situational emotions in mathematics classes.

Motivational Drivers in Implant Therapy: A Novel Treatment Motivation Scale.

Aim This study aims to assess patient motivation during implant therapy using the newly developed implant treatment motivation scale. Materials and methods A questionnaire study was conducted, consisting of 15 questions designed to explore the motivating factors behind patients' decision to undergo implant therapy. A total of 50 patients about to undergo implant treatment at the Departments of Periodontology, Oral and Maxillofacial Surgery, and Prosthodontics participated in the study.  Results Analysis revealed a consistently high level of motivation (intrinsic and extrinsic) among all patients undergoing implant therapy. Conclusions The findings highlight the crucial role of motivation in treatment-seeking behavior, emphasizing the importance of dentists in motivating and guiding patients through the process of implant therapy.

Analysis of Factors Contributing to State Body Appreciation during Exercise.

This cross-sectional study aimed to analyse the factors contributing to state body appreciation (SBA) during exercise. After providing their informed consent, 200 study participants (mean age 30.0 ± 9.4 years, 72.0% were men) filled in an online questionnaire immediately after the completion of resistance training (n = 125), cardiovascular exercise (n = 55), or functional/interval group exercise (n = 20) sessions. The study measures included socio-demographic variables, body mass index (BMI), the duration of involvement in sports, SBA, state body surveillance (SBS), state mindfulness in physical activity, state intrinsic exercise regulation, and perceived pleasantness during exercise. The results showed that exercisers involved in sports for >2 years and those whose body weight was within a healthy range (<25.0 kg/m2) demonstrated higher SBA and mindfulness during exercise, lower SBS, more intrinsic exercise regulation, and higher satisfaction during physical activity compared to exercisers with less exercise experience (≤2 years) and a body weight higher than a healthy range (≥25.0 kg/m2). The negative effects of being overweight or obese were more pronounced in individuals with ≤2 years of sports participation, except regarding body surveillance and monitoring the mind. The factors significantly contributing to SBA during the exercise sessions were a longer duration of involvement in sports, a lower BMI and SBS, and greater mindful body acceptance and exercise pleasantness. Decreasing SBS and enhancing mindful body acceptance, pleasantness, and intrinsic motivation during exercise might significantly contribute to SBA in physical activity. These results can inform physical-activity-based programmes aiming to promote a positive body image. Also, these results show that it is important to increase education and develop competencies for fitness coaches to create inclusive and positive-body-image-promoting sports environments.

Student motivation to study music and sport - a comparison between study subjects and study programs on intrinsic and extrinsic motivational aspects.

Instruction: In both subjects, music and sport, the engagement with the subject content - learning an instrument or training in a sports club - usually begins in early childhood. This makes these subjects special and similar. It is therefore of interest to examine the motivation for choosing music and sport as subjects for university study. Methods: In the present investigation, 151 students at the beginning of their university studies were examined. Among these were 110 music university students in the Bachelor of Music (B.Mus.) and music teacher education program, and 41 sport university students in the Bachelor of Science (B.Sc.) and sport teacher education program. The study contained a custom-made questionnaire on sociodemographic data, questions on study choice alternatives and biographical musical or sporting background, as well as two standardized questionnaires on motivation for enrollment (STUWA) and on aspects that are important for the profession. Results: Music and sport students were at a rather high and similar level of intrinsic motivation to study their subjects. However, materialistic goals motivated the teacher education students more than the bachelor's students with an artistic program. The difference between the study programs was also found in the context of extrinsic-social motivation, where the teacher training students answered with higher scores. With regard to socially-induced motivation, it was shown that music students and sport teacher education students were more socially induced to study the respective subject compared to the general student population. With regard to uncertainty when choosing a course, it was found that Bachelor of Music students were more certain that they wanted to study exactly their particular subject. The ages at which music and sport were started in childhood were similar, but the first-year music students were younger than the sport students were. Compared to sports students, music students decided their area of study earlier, and bachelor's students in music in particular had fewer alternative study options than sports students. Discussion: The results provide a differentiated picture of student motivation to study and thus allow a deeper insight into the subject cultures of music and sport. They also open up opportunities for follow-up studies in comparison with other study subjects and programs.

Influence of teacher autonomy support in feedback on high school students' feedback literacy: the multiple mediating effects of basic psychological needs and intrinsic motivation.

This research presents and confirms an intermediary model, deeply anchored in self-determination theory, to dissect the influence of Chinese high school students' core psychological needs and intrinsic drive on the nexus between educators' autonomous backing and students' proficiency in feedback literacy, highlighting the mediating roles of these elements. A survey of 704 Chinese senior high school students, including 319 males and 385 females, employed the Feedback Literacy Scale, Basic Psychological Needs Scale, Intrinsic Motivation Scale, and Perceived Teacher Autonomy Support Scale. The study's discoveries illuminate that educators' autonomous support not only directly amplifies students' feedback literacy but also has an indirect impact through the intermediation of basic psychological needs and intrinsic motivation, along with their interconnected dynamics. This inquiry not only deepens our grasp of the mechanisms interlinking teacher support with feedback literacy but also critically evaluates the findings to proffer targeted recommendations, thereby enhancing our comprehension of the underlying processes and guiding educational practices and student development.

Curiosity model policy optimization for robotic manipulator tracking control with input saturation in uncertain environment.

In uncertain environments with robot input saturation, both model-based reinforcement learning (MBRL) and traditional controllers struggle to perform control tasks optimally. In this study, an algorithmic framework of Curiosity Model Policy Optimization (CMPO) is proposed by combining curiosity and model-based approach, where tracking errors are reduced via training agents on control gains for traditional model-free controllers. To begin with, a metric for judging positive and negative curiosity is proposed. Constrained optimization is employed to update the curiosity ratio, which improves the efficiency of agent training. Next, the novelty distance buffer ratio is defined to reduce bias between the environment and the model. Finally, CMPO is simulated with traditional controllers and baseline MBRL algorithms in the robotic environment designed with non-linear rewards. The experimental results illustrate that the algorithm achieves superior tracking performance and generalization capabilities.

Active sensing with predictive coding and uncertainty minimization.

We present an end-to-end architecture for embodied exploration inspired by two biological computations: predictive coding and uncertainty minimization. The architecture can be applied to any exploration setting in a task-independent and intrinsically driven manner. We first demonstrate our approach in a maze navigation task and show that it can discover the underlying transition distributions and spatial features of the environment. Second, we apply our model to a more complex active vision task, whereby an agent actively samples its visual environment to gather information. We show that our model builds unsupervised representations through exploration that allow it to efficiently categorize visual scenes. We further show that using these representations for downstream classification leads to superior data efficiency and learning speed compared to other baselines while maintaining lower parameter complexity. Finally, the modular structure of our model facilitates interpretability, allowing us to probe its internal mechanisms and representations during exploration.

Longitudinal effects of basic psychological need support on the development of intrinsic motivation and perceived competence in physical education. A multilevel study.

Background: Grounded in self-determination theory, this article deals with a multidimensional measurement of the support of the basic psychological needs and the individual and combined effects on the development of intrinsic motivation and perceived competence in physical education. In addition to the supportive teacher behaviors of autonomy support, competence support and relatedness support, peer relatedness support is examined as an additional factor. Methods: A total of 1,047 students from 72 classes from various German-speaking Swiss cantons took part in the study. The hypothesized four factorial structure was analyzed using multilevel confirmatory factor analyses. Longitudinal measurement invariance testing of intrinsic motivation and perceived competence indicates scalar measurement invariance. Multilevel regression analyses were specified to analysis the longitudinal effects on the development of intrinsic motivation and perceived competence, whereby both the effects of the individual factors as well as the adjusted effects under the inclusion of all predictors were examined. Results: Results of multilevel confirmatory factor analysis indicate that the hypothesized four-factor model (e.g., CFI = 0.97; TLI = 0.96; RMSEA = 0.04; SRMR between = 0.11) is to be favored over alternative models at both levels. Regarding the prediction of the development of intrinsic motivation and perceived competence our study underlines the predictive value of basic psychological need support. The models that examine the effects of the individual predictors indicate that the effects are largely consistent with expectations at both the class and individual level. At class level, however, autonomy support appears to be no significant predictor for the development of intrinsic motivation (p < 0.10), but for perceived competence (p < 0.05). Peer relatedness support is a significant predictor for both outcome variables at both levels of analysis. Regarding the simultaneous integration of all predictors, only the effects of peer relatedness support remain significant for both outcome variables. Discussion: The empirical support of the multidimensionality of the instrument is particularly interesting in the context of the common conceptualization of a unidimensional measurement of autonomy support or a composite factor of psychological need support, whereby only few studies have adequately tested the factorial validity. Although significant effects of supportive teacher behaviors can be demonstrated in the multilevel regression analyses, it is also indicated that the different dimensions lack of incremental predictive validity. Particularly noteworthy is the rarely investigated role of peer relatedness support, which has been shown to be a meaningful predictor, even when supportive teacher behaviors are taken into account.

Partnered dance evokes greater intrinsic motivation than home exercise as therapeutic activity for chemotherapy-induced deficits: secondary results of a randomized, controlled clinical trial.

Introduction: Dance has been proposed to support superior intrinsic motivation over non-dance forms of therapeutic physical activity. However, this hypothesis has yet to be evaluated empirically, particularly among populations living with neuropathology such as survivors of cancer with neurologic complications from chemotherapy treatment. Questions about motivation are relevant to clinical outcomes because motivation mediates neuroplasticity. We conducted this secondary analysis of a randomized-controlled study to begin to investigate the relationships between personal motivation and neurophysiologic effects of dance-based intervention for healthy aging among populations with neurologic complications of cancer. Methods: We measured motivation using the Intrinsic Motivation Inventory, a validated patient-reported outcome from the psychological approach of Self Determination Theory. We assessed intrinsic motivation, extrinsic motivation, and satisfaction with intervention within a randomized controlled trial of dance versus exercise designed to alleviate symptoms of chemotherapy-induced impairment. Fifty-two survivors of breast cancer with chemotherapy-induced neuropathy diagnosis and associated sensorimotor functional deficits were randomized (1:1) to 8 weeks of partnered dance or home exercise, performed biweekly (NCT05114005; R21-AG068831). Results: While satisfaction did not differ between interventions, intrinsic motivation was higher among participants randomized to dance than those randomized to exercise (p < 0.0001 at all timepoints: 2 weeks, 4 weeks, 6 weeks, and 8 weeks of intervention), as was extrinsic motivation at 2 weeks (p = 0.04) and 8 weeks (p = 0.01). Discussion: These data provide evidence that social dance is more motivating than the type of home exercise generally recommended as therapeutic physical activity. The results inform directions for future study of the effect of dance-based therapeutics on embodied agency, neuroplastic changes, and clinically-relevant neuropathic improvement.

The role of self-esteem on motivational aspects of Greek blind athletes competing in individual and team sports.

Physical activity and sports can be considered important sources of motivation for people with visual impairments; however limited attention has been given to blind peoples' involvement in sports and to the intra-personal variables such as self-esteem and motivation that affect their sport participation. The purpose of the present study was a) to explore the relationship between self-esteem and intrinsic motivation in blind athletes, and b) to assess the levels of self-esteem and intrinsic motivation and identify differences in intrinsic motivation and self-esteem as a function of gender and sport type (individual-team sports). Participants were 78 (27 females) Greek blind athletes (30.29 ± 1.18 years of age) competing in team (N = 44) and individual (N = 34) sports. Participants completed the Intrinsic Motivation Inventory questionnaire (IMI) and Rosenberg Self-Esteem Scale (RSES) questionnaire. The findings revealed that high values on self-esteem could predict blind athletes' perceived competence (p = .001) and strengthen their intrinsic motivation while enabling them to regulate pressure and tension (p < .05). However, female athletes appeared to be more pressured than males (p < .05), and interestingly, team sport athletes scored higher in intrinsic motivation than individual sports athletes (p < .05). The findings provide useful insights regarding the role of self-esteem in blind athletes' motivational profiles and draw attention to the role of perceived competence in blind athletes' sporting experiences, emphasizing that team sport context may serve as a fertile ground for enhancing intrinsic motivation.

Intrinsic motivation between face-to-face and blended learning in surgical clinical education.

Objective: The variability and opportunistic nature of surgical clinical education is the main problem for effective teaching and training of medical students. Incorporating online mediums including discussion forums, interactive videos/scenarios, static pages, and quizzes is known as blended learning (BL). This study aimed to compare the intrinsic motivation of surgical students enrolled in blended learning to those enrolled in face-to-face teaching (f2f teaching). Methods: A quasi-experimental, cross-over study was conducted in Surgical Unit-I and Surgical Unit-II of Dow University Hospital, Karachi, from March to August 2014. A total of 31 students participated and were exposed to two different teachings. For the first four weeks, Group A was posted in Surgical-I (f2f teaching) and Group B in Surgical-II (BL). Both groups were taught the same contents with the same schedule. The F2F group had clinical exposure to real patients, and small group discussions (SGDs) while The BL group students were exposed to an additional online learning component. Intrinsic Motivation Inventory (IMI) was administered at the end of four weeks and groups were swapped. Exchanged groups were again taught the same contents with the same schedule for another four weeks and IMI was administered. Results: Fifty-eight students completed IMI; 28 in f2f and 30 in BL group. There was a significant difference in all four subscales of IMI between the two groups. In three subscales, students in BL were more motivated as compared to f2f (p<0.01). Students in f2f experienced more perceived tension than in BL (p<0.048). Conclusion: This study concluded that blended surgical learning programs keep medical students more intrinsically motivated to learn. By utilizing online learning, superior educational opportunities for students can be cultivated. It can result in enhanced faculty effectiveness and efficiency as well.

Effects of (de)motivating supervision styles on junior doctors' intrinsic motivation through basic psychological need frustration and satisfaction: an experimental vignette study.

In clinical practice, junior doctors regularly receive supervision from consultants. Drawing on Basic Psychological Needs Theory, consultants' supervision styles are likely to affect junior doctors' intrinsic motivation differently in terms of psychological need frustration and psychological need satisfaction. To examine the effects of (de)motivating supervision styles, we conducted two experimental vignette studies among junior doctors. In Study 1 (N = 150, 73.3% female), we used a 2 (need support: high vs. low) x 2 (directiveness: high vs. low) between-subjects design and, in Study 2, a within-subjects design with the same factors (N = 46, 71.7% female). Both studies revealed a consistent positive effect of need-supportive supervision styles on psychological need satisfaction (+), need frustration (-), and intrinsic motivation (+). Particularly in Study 2, the main effect of need-supportive styles was strengthened by supervisor's directiveness. Moreover, in both studies, the effects of supervision styles on intrinsic motivation were explained through psychological need frustration and psychological need satisfaction. We discuss the implications of these findings for postgraduate clinical training.

Common Relationship Between Causality Orientation and the Prefrontal Region in Psychiatric Disorders as Revealed by Diffusional Kurtosis Imaging.

Background Motivation dysregulation is common in several psychiatric disorders. However, little is known about the relationships between motivation and the regional brain areas involved. We evaluated the relationships between brain microstructural features and causality orientation in patients with schizophrenia, major depressive disorder (MDD), and bipolar disorder (BD) using diffusional kurtosis imaging (DKI) techniques. Methods Forty patients with MDD, 36 with BD, and 30 with schizophrenia underwent DKI and assessment using the General Causality Orientation Scale (GCOS). We analyzed the DKI index and the GCOS subscales. Results The psychiatric patients showed significant positive correlations between the GCOS-autonomy orientation score and the mean kurtosis (MK) values in the prefrontal regions, orbitofrontal regions, and posterior cingulate cortex. When the analyses were performed separately by disease and gender, a positive correlation was found between the GCOS-autonomy orientation score and the MK values in the left prefrontal regions transdiagnostically, especially among female patients with MDD, BD, and schizophrenia. Conclusions A similar association between intrinsic motivation and MK value in the left prefrontal cortex was suggested in patients with schizophrenia, MDD, and BD. The commonality of this association among these disorders might lead to the discovery of a new biomarker for psychiatric clinical research.

Exploring e-sports fans' motivation for watching live streams based on self-determination theory.

This study seeks to examine the multifaceted influences of diverse motivational factors on the live streaming engagement of e-sports fans based on self-determination theory. While previous research has focused on the offline participation in e-sports events, the shift towards live streaming engagement has created a new and underexplored area: the motivations for live streaming viewing among e-sports fans. Consequently, this research develops an e-sports Live Streaming Viewing Motivation Scale for evaluating both intrinsic and extrinsic motivations underlying e-sports fans' live streaming engagement, and then utilises SPSS 26.0 and AMOS 26.0 to assess the reliability and validity of the scale. Subsequently, multiple linear regression analysis of 1052 questionnaires is employed to construct models and evaluate hypotheses. Findings indicate that : (1) Intrinsic motivation exhibits significant impact on the live viewing behaviour of e-sports fans. (2) However, the impact of extrinsic motivation is insignificant. (3) When both intrinsic and extrinsic motivations coexist, intrinsic motivation maintains a positive impact, whereas extrinsic motivation demonstrates a negative influence. (4) The motivational influence is multifaceted; notably, dimensions such as idol worship, leisure entertainment, and competitive stimulation positively affect live viewing motivation, while belonging identification, social engagement, and peripheral activities exert a negative impact. In conclusion, intrinsic motivation emerges as the primary driving force behind e-sports fans' live streaming viewing behaviour. Extrinsic motivation fails to independently influence live streaming engagement and even dampens enthusiasm when combined with intrinsic motivation. Theoretically, this study contributes to the existing literature on Self-determination theory and motivations behind e-sports live streaming viewing behaviour. It not only refines the motivation scale, but also elucidates the impact of various motivations on viewing behaviour. Practically, it provides insights for optimising e-sports products and services.

Parental influence on urban adolescents' physical activity experience.

As important socializing agents of adolescents, parents may substantially influence adolescents' physical activity but their roles in adolescents' physical activity experience have not been sufficiently studied. Furthermore, there is a dearth of research on potential mechanisms through which parents may promote adolescents' positive physical activity experience. Using a longitudinal sample of 464 urban and primarily Hispanic and African American adolescents, this study examined the impact of parental support on adolescents' physical activity experience. Results of structural equation modeling showed that after controlling for adolescents' gender, body mass index, and perceived overall health, parental support positively affected adolescents' restructuring ability (i.e., ability to construct meaningful and satisfying activities during unpleasant experiences) and intrinsic motivation (i.e., activity participation driven by inherent interest and enjoyment) in physical activity, which in turn positively affected adolescents' physical activity experience. No significant gender differences were found in these relationships. Theoretical and practical implications are discussed.

How occupational physicians pay attention to the values of employees: a qualitative study.

PURPOSE: The Dutch Association for Occupational Medicine considers employee values to be an essential pillar in occupational medicine. The occupational physician should focus on what an employee finds valuable. However, it is unclear how occupational physicians comply with this policy and pay attention to employee values. The present study aims to fill this gap by mapping to what extent occupational physicians pay attention to employee values. METHOD: We used an exploratory qualitative research method through in-depth interviews with 10 Dutch occupational physicians. Additionally, two non-participating observations were conducted. RESULTS & CONCLUSION: The results show that values remain mostly implicit and are applied intuitively or unconsciously but not explicitly. Hence, the ethical requirements of the Dutch Association for Occupational Medicine policy remain underexposed and under-executed. Multiple facets foster or impede a conversation about values. As far values were mentioned they were mainly extrinsic, social, and prestige-oriented. Intrinsic values were hardly mentioned. However, a few occupational physicians explicitly stated that they pay attention to values and reported that heeding to employee values contributes to better collaboration and decision-making with the employee. We argue that paying attention to intrinsic values may improve the overall work quality of occupational physicians and benefit employee well-being.

OPTIMAL theory's claims about motivation lack evidence in the motor learning literature.

Motivation is commonly recognized by researchers and practitioners as a key factor for motor learning. The OPTIMAL theory of motor learning (Wulf & Lewthwaite, 2016) claims that practice conditions that enhance learners' expectancies for future successful outcomes or that are autonomy supportive are motivating, thus leading to better learning. To examine the current evidence of the association between motivation and motor learning, we searched the literature for studies that manipulated expectancies and/or autonomy support. Specifically, our goals were to assess whether these manipulations resulted in group differences in motivation and, if so, whether increased motivation was associated with learning advantages. Results showed that out of 166 experiments, only 21% (n = 35) included at least one measure of motivation, even though this is the main factor proposed by OPTIMAL theory to explain the learning benefits of these manipulations. Among those, only 23% (n = 8) found group-level effects on motivation, suggesting that these manipulations might not be as motivating as expected. Of the eight experiments that found a group-level effect on motivation, five also observed learning benefits, offering limited evidence that when practice conditions increase motivation, learning is more likely to occur. Overall, the small number of studies assessing motivation precludes any reliable conclusions on the association between motivation and motor learning from being drawn. Together, our results question whether manipulations implemented in the research lines supporting OPTIMAL theory are indeed motivating and highlight the lack of sufficient evidence in these literatures to support that increased motivation benefits motor learning.
