Psychological Flow In A Physical Task

Psychological flow describes the mental phenomenon that takes place during intense engagement with a task (Jackson & Csikszentmihalyi, 1999). Its components have been operationalized through the development of the Flow State Scale (Jackson & Eklund, 2002). As feedback has been shown to be a critical element for the facilitation of a flow experience (Moneta, 2012), the current study sought to investigate the effect of differential feedback on psychological flow outcomes using the FSS as the dependent variable. The feedback manipulation featured three experimental groups; control, positive, and negative. This study also accounted for the personality trait of perfectionism as a variable influencing the experience of flow. Following the completion of a personality measure, participants engaged in a bolt threading task for ten minutes, then reported the time they perceived to have spent on the task as well as the outcome of their flow experience. The feedback conditions were created by the use of different size containers for participants to place their nut and bolt pairs in, and thus feedback was inherent in the task. The study found that feedback played an important role in the outcome of a flow experience. The positive feedback condition was more conducive to flow than the negative feedback condition. Furthermore, those in the positive condition outperformed those in the negative condition during the ten minutes. Goal clarity and feedback clarity differed significantly across feedback manipulations. Perfectionism¿s impact on the outcome of flow was more pronounced in the negative feedback condition than the positive or control conditions. In settings where engagement and performance are imperative, ample attention should be given to the feedback processes present in the situation.

Anxiety, Depression, and General Psychological Distress in Patients with Coronary Slow Flow

AbstractBackground:The relationship between psychiatric illness and heart disease has been frequently discussed in the literature. The aim of the present study was to investigate the relationship between anxiety, depression and overall psychological distress, and coronary slow flow (CSF).Methods:In total, 44 patients with CSF and a control group of 50 patients with normal coronary arteries (NCA) were prospectively recruited. Clinical data, admission laboratory parameters, and echocardiographic and angiographic characteristics were recorded. Symptom Checklist 90 Revised (SCL-90-R), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI) scales were administered to each patient.Results:The groups were comparable with respect to age, sex, and atherosclerotic risk factors. In the CSF group, BAI score, BDI score, and general symptom index were significantly higher than controls (13 [18.7] vs. 7.5 [7], p = 0.01; 11 [14.7] vs. 6.5 [7], p = 0.01; 1.76 [0.81] vs. 1.1[0.24], p = 0.01; respectively). Patients with CSF in more than one vessel had the highest test scores. In univariate correlation analysis, mean thrombolysis in myocardial infarction (TIMI) frame counts were positively correlated with BAI (r = 0.56, p = 0.01), BDI (r = 0.47, p = 0.01), and general symptom index (r = 0.65, p = 0.01). The psychiatric tests were not correlated with risk factors for atherosclerosis.Conclusion:Our study revealed higher rates of depression, anxiety, and overall psychological distress in patients with CSF. This conclusion warrants further studies.

Do implicit motives and basic psychological needs interact to predict well-being and flow? Testing a universal hypothesis and a matching hypothesis

Self-Determination Theory (Deci and Ryan in Intrinsic motivation and self-determination in human behavior. Plenum Press, New York, 1985) suggests that certain experiences, such as competence, are equally beneficial to everyone’s well-being (universal hypothesis), whereas Motive Disposition Theory (McClelland in Human motivation. Scott, Foresman, Glenview, IL, 1985) predicts that some people, such as those with a high achievement motive, should benefit particularly from such experiences (matching hypothesis). Existing research on motives as moderators of the relationship between basic need satisfaction and positive outcomes supports both these seemingly inconsistent views. Focusing on the achievement motive, we sought to resolve this inconsistency by considering the specificity of the outcome variables. When predicting domain-specific well-being and flow, the achievement motive should interact with felt competence. However, when it comes to predicting general well-being and flow, felt competence should unfold its effects without being moderated by the achievement motive. Two studies confirmed these assumptions indicating that the universal and matching hypotheses are complementary rather than mutually exclusive.

Longitudinal platelet reactivity to acute psychological stress among older men and women

Platelet reactivity to acute stress is associated with increased cardiovascular disease risk; however, little research exists to provide systematic methodological foundations needed to generate strong longitudinal research designs. Study objectives were: 1) to evaluate whether markers of platelet function increase in response to an acute psychological stress test among older adults, 2) to establish whether reactivity remains robust upon repeated administration (i.e. three occasions approximately 1 year apart), and 3) to evaluate whether two different acute speech stress tasks elicit similar platelet responses. The 149 subjects (mean age 71 years) gave a brief impromptu speech on one of two randomly assigned topics involving interpersonal conflict. Blood samples drawn at baseline and post-speech were assayed using flow cytometry for platelet responses on three outcomes (% aggregates, % P-selectin expression, and % fibrinogen receptor expression). Three-level hierarchical linear modeling analyses revealed significant stress-induced increases in platelet activation on all outcomes (p < 0.001). No significant habituation on any measure was found. Additional reactivity differences were associated with male gender, history of myocardial infarction, and use of aspirin, statins, and antidepressants. The results demonstrate that laboratory acute stress tests continued to produce robust platelet reactivity on three activation markers among older adults over 3 years.

How basic need satisfaction and dispositional motives interact in predicting flow experience in sport

We have integrated the basic psychological needs approach from self-determination theory with motive disposition theory in order to enhance the prediction of flow experience in sports. We hypothesize that an environment that enables people to fulfill their basic psychological needs for competence and social relatedness results in flow. Additionally, we assume that the effect of competence need satisfaction is moderated by the achievement motive and that the effect of need-for-relatedness satisfaction is moderated by the affiliation motive. Four studies show the expected positive effects of need satisfaction on flow and further confirm that high achievement and affiliation-motivated individuals benefit more from competence and relatedness sports environments, respectively, than individuals low in these motives.

Fit between situational and dispositional goal orientation, and its effects on flow experience and affective well-being during sports.

Flow represents an optimal psychological state that is intrinsically rewarding. However, to date only a few studies have investigated the conditions for flow in sports. The present research aims to expand our understanding of the psychological factors that promote the flow experience in sports, focusing on the person-goal fit, or more precisely on the athletes’ situational and dispositional goal orientations. We hypothesize that a fit between an athlete’s situational and dispositional approach versus avoidance goal orientation should promote flow, whereas a non-fit will hinder flow during sports. In addition to the flow experience, we hypothesize that an athlete’s affective well-being is also affected by the person-goal fit. Here our assumptions are theoretically rooted in research on person-environment fit. An experimental study in an ecologically valid sport setting was conducted in order to draw causal conclusions and derive useful strategies for the practice of sports. Specifically, we investigated 67 male soccer players from a regional amateur league during a regular training session. They were randomly assigned to an approach or avoidance goal group and asked to take five penalty shots. Immediately afterwards, their flow experience and affective well-being during the penalty shootout were measured. As predicted, soccer players with a strong dispositional approach goal orientation experienced more flow and reported higher affective well-being when they were assigned to the approach goal. In contrast, soccer players with a strong dispositional avoidance goal orientation benefited from being assigned an avoidance goal in terms of their flow experience and affective well-being. The results are discussed critically with respect to their theoretical and practical implications.

Flow-evoking activities foster recovering from Depletion

Self-control is assumed to be a limited resource that becomes drained with use. However, high motivation such as flow experience may compensate for the reduced ability to self-regulate. Results revealed that the more flow students experienced the less depletion of self-regulation was reported.

Motivación, flow e intención de práctica físico-deportiva en estudiantes de educación física de España y Latinoamérica

A pesar de los innegables beneficios físicos y psicosociales que la práctica de actividad física tiene para la población en las últimas décadas se observa un importante descenso en el nivel de práctica de actividad física durante la adolescencia. La Educación Física (EF) es una asignatura presente en las primeras etapas educativas de los currículums de todos los países y supone para la población infantil y adolescente, durante el periodo de escolarización obligatoria, un entorno de contacto cotidiano con la actividad física y deportiva lo que explica el creciente interés que existe por investigar en este contexto y extraer conclusiones que puedan ayudar a revertir el proceso de progresivo abandono de la práctica en estas edades. El presente trabajo se centra en un periodo, la adolescencia, especialmente sensible al abandono de la práctica de actividad física. Apoyándonos en tres de los marcos teóricos más importantes de los últimos años - Teoría de Metas de Logro, Teoría de la Autodeterminación y Teoría del Flow - hemos realizado un diseño con tres estudios complementarios que nos permitan avanzar en el conocimiento de las variables que afectan a esta realidad. En el primero de los estudios, en el que participaron 3990 estudiantes de EF de España, Argentina, Colombia y Ecuador con edades comprendidas entre 12 y 18 años, se fijaron como objetivos el establecimiento de perfiles motivacionales en estudiantes de EF considerando las orientaciones motivacionales, la motivación intrínseca y el flow disposicional; la comprobación de la posible estabilidad de los perfiles establecidos en cuatro países diferentes; y el análisis de la relación entre los perfiles motivacionales establecidos con la práctica de actividad física realizada en la actualidad y la intención de ser activo en el futuro. Los resultados revelaron la existencia de tres perfiles motivacionales en los estudiantes: perfil de motivación baja-moderada, perfil de motivación de alta motivación con bajo ego y perfil de alta motivación. Se encontraron similitudes en los perfiles motivacionales obtenidos en los cuatro países analizados, sugiriéndose la posibilidad de que la lengua materna compartida pueda ser una variable de influencia en la existencia de patrones conductuales similares. La orientación al ego resultó ser un elemento diferenciador en la relación de los dos perfiles que mostraron niveles más altos de motivación intrínseca, flow disposicional y orientación a la tarea con las variables de práctica. Mayores niveles de orientación al ego determinaron mayores valores de práctica e intención de práctica. En el segundo estudio, en el que participaron 365 estudiantes de EF de España, Argentina y Colombia con edades comprendidas entre 12 y 16 años, se testó un modelo explicativo de la intención de ser físicamente activo en el futuro en estudiantes de EF poco motivados introduciendo el flow disposicional como variable explicativa junto a las orientaciones motivacionales y la motivación intrínseca. El modelo de ecuaciones estructurales testado muestra que tanto la orientación al ego como la orientación a la tarea y la motivación intrínseca predijeron el flow disposicional. No se encontró un efecto significativo de la orientación a la tarea sobre la motivación intrínseca, ni de esta sobre la intención de práctica de AFD en el futuro. El flow disposicional resultó ser un mediador entre ambas orientaciones motivacionales y dicha intención, adquiriendo un papel relevante en la predicción de la intención de realizar actividad física en el futuro en los sujetos con poca motivación hacia la clase de EF. En el último estudio, con una muestra de 53 estudiantes de EF pertenecientes a dos clases de segundo curso de ESO con edades comprendidas entre 13 y 15 años, se analizó el efecto de una intervención de apoyo a las NPB sobre la satisfacción de las mismas, la motivación intrínseca, la disposición a experimentar flow y la intención de ser físicamente activo en el futuro; estudiándose también el efecto de la misma sobre ciertas variables presentes en el proceso de enseñanza-aprendizaje tales como la diversión, el aprendizaje y el gusto hacia el contenido y la metodología empleada. La intervención resultó efectiva en la mejora de todas las variables motivacionales analizadas a excepción de la satisfacción de la necesidad de relaciones sociales, variable que podría ser más difícilmente modificable en tanto que los grupos de clase suelen permanecer estables a lo largo de esta etapa educativa. Los alumnos de la condición experimental presentaron niveles más elevados de diversión, aprendizaje y gusto hacia el contenido y la metodología empleada. ABSTRACT Despite the undeniable physical and psychological benefits that physical activity has on health, a significant drop in the level of physical activity during adolescence has been observed over the last few decades. Physical education (PE) is present in the early stages of educational curricula of all countries, creating an environment in which children and adolescents can maintain daily contact with sport and physical activity during the period of compulsory education. There is thus a growing interest in research within this context, helping to draw conclusions aimed at reversing the progressive decline of physical activity in this age bracket. The work presented here focuses on adolescence – a period particularly sensitive when faced with declining rates of physical activity. Relying on three of the most important recent theoretical frameworks – Achievement Goal Theory, Self-Determination Theory and Flow Theory – we have carried out a design using three complementary studies that allow us to advance the understanding of variables affecting this reality. The first two studies employ a correlational methodology while the third follows a quasi-experimental design. The objectives of the first study, with the participation of 3990 PE students aged 12 to 18 from Spain, Argentina, Colombia and Ecuador, were: a) to establish motivational profiles in physical education students taking into consideration motivational orientations, intrinsic motivation and dispositional flow; b) to check the possible stability of the established profiles in the four countries; and c) to analyze the relationship between motivational profiles and both current levels of physical activity and intention to be physically active in the future. Results revealed the existence of three motivational profiles: low-moderate motivation profile, high motivation and low ego profile and high motivation profile. Similarities were found across the four countries, which presents the possibility that sharing the same mother tongue might influence the existence of similar behavioral patterns. Amongst the profiles that showed the highest levels of intrinsic motivation, dispositional flow and task orientation with practice variables, ego orientation became apparent as a differentiating element. Higher levels of ego orientation correlated with higher levels both in current level of physical activity and intention to be physically active in the future. In the second study, with the participation of 365 PE students aged 12 to 16 from Spain, Argentina and Colombia, an explanatory model of the intention to be physically active within the low-moderate motivation profile was tested, including dispositional flow as an influence variable together with motivational orientations and intrinsic motivation. The structural model equation in the low-moderate motivation profile shows some differences with respect to findings of similar studies using heterogeneous samples in motivational profiles. It was found that ego orientation, task orientation and intrinsic motivation predicted dispositional flow. No significant effects of task orientation on intrinsic motivation, or of intrinsic motivation on intention to be physically active in the future were found. Dispositional flow emerged as a mediator between both motivational orientations and intention, acquiring an important role in the prediction of future intentions to be physically active in adolescents who show low levels of motivation towards physical education. In the last of the three studies, with the participation of 53 PE students drawn from two classes in the second year of secondary education aged 13 to 15, the effect of an intervention to support basic psychological needs was tested against the satisfaction of these needs, intrinsic motivation, disposition to experience flow and intention to be physically active in the future. Alongside this, the aforementioned intervention was tested on certain variables present in the teaching-learning process such as fun, learning and taste for the activity and methodology. Supportive intervention was effective in improving all the motivational variables, except for the satisfaction of the relatedness variable, which may be more difficult to modify as class groups tend to remain stable throughout this educational state. Students in the experimental condition showed higher levels of fun, learning and taste for the content and methodology.

Beam-energy Dependence Of The Directed Flow Of Protons, Antiprotons, And Pions In Au+au Collisions.

Rapidity-odd directed flow (v1) measurements for charged pions, protons, and antiprotons near midrapidity (y=0) are reported in sNN=7.7, 11.5, 19.6, 27, 39, 62.4, and 200 GeV Au+Au collisions as recorded by the STAR detector at the Relativistic Heavy Ion Collider. At intermediate impact parameters, the proton and net-proton slope parameter dv1/dy|y=0 shows a minimum between 11.5 and 19.6 GeV. In addition, the net-proton dv1/dy|y=0 changes sign twice between 7.7 and 39 GeV. The proton and net-proton results qualitatively resemble predictions of a hydrodynamic model with a first-order phase transition from hadronic matter to deconfined matter, and differ from hadronic transport calculations.

Electrochemical Oxidation Of Landfill Leachate In A Flow Reactor: Optimization Using Response Surface Methodology.

Response surface methodology based on Box-Behnken (BBD) design was successfully applied to the optimization in the operating conditions of the electrochemical oxidation of sanitary landfill leachate aimed for making this method feasible for scale up. Landfill leachate was treated in continuous batch-recirculation system, where a dimensional stable anode (DSA(©)) coated with Ti/TiO2 and RuO2 film oxide were used. The effects of three variables, current density (milliampere per square centimeter), time of treatment (minutes), and supporting electrolyte dosage (moles per liter) upon the total organic carbon removal were evaluated. Optimized conditions were obtained for the highest desirability at 244.11 mA/cm(2), 41.78 min, and 0.07 mol/L of NaCl and 242.84 mA/cm(2), 37.07 min, and 0.07 mol/L of Na2SO4. Under the optimal conditions, 54.99 % of chemical oxygen demand (COD) and 71.07 ammonia nitrogen (NH3-N) removal was achieved with NaCl and 45.50 of COD and 62.13 NH3-N with Na2SO4. A new kinetic model predicted obtained from the relation between BBD and the kinetic model was suggested.
