A person-centered approach to achievement goal orientations in competitive tennis players: Associations with motivation and mental toughness     

Richard Gregory Cowden  Nicolas Mascret  Timothy Ryan Duckett 《运动与健康科学(英文)》2021,10(1):73

BackgroundResearch on achievement goal orientations in sport has typically relied on the use of variable-centered approaches that tend to overlook population heterogeneity. In this study, we used a person-centered approach to identify subgroups of competitive tennis players according to unique combinations of achievement goal orientations and tested for subgroup differences in motivation and mental toughness.MethodsA sample of 323 competitive tennis athletes (69.35% male) between 15 and 25 years of age (17.60 ± 2.40 years, mean ± SD) completed the 3 × 2 Achievement Goal Questionnaire for Sport, Sport Motivation Scale II, and Mental Toughness Index. Latent profile analysis was used to identify unique combinations of achievement goal orientations. Comparisons between latent subgroups on autonomous motivation, controlled motivation, and mental toughness were performed using analysis of variance.ResultsLatent profile analysis supported 3 distinct patterns of achievement goal profiles that were primarily distinguishable based on valence of competence (i.e., approach vs. avoidance). Analyses of variance indicated that athletes who were classified into subgroups that endorsed approach types of goals (regardless of the types of avoidance goals they endorsed) reported higher levels of autonomous motivation and mental toughness.ConclusionResults indicated that athletes tend to pursue a number of achievement goals collectively rather than in isolation. Although approach goals are more commonly linked to adaptive psychological functioning and positive outcomes, avoidance goals may also be associated with desirable psychological characteristics if they are pursued in conjunction with approach types of achievement goals.  相似文献   

Responses of Free-ranging Rhesus Monkeys to a Natural Form of Social Separation. I. Parallels with Mother-Infant Separation in Captivity     

C. M. Berman  K. L. R. Rasmussen  Stephen J. Suomi 《Child development》1994,65(4):1028-1041

Observations of 23 free-ranging rhesus monkey infants on Cayo Santiago, Puerto Rico, indicated that mothers' first postpartum estrous periods were marked by large increases in the amount of time infants were separated from their mothers, by disturbances in mother-infant relationships, and by increases in infant distress behavior. When their mothers resumed mating, most infants showed signs of agitation; a few briefly showed indications of depression. Male infants responded to their mothers' resumption of mating by playing more, whereas females engaged in less play and more allogrooming. The results suggest ( a ) that basic parallels exist between the behavioral responses of rhesus infants to their mothers' resumption of mating in the field and to forcible separation from their mothers in captivity and ( b ) that early separation experiences may play a role in the normal development or manifestation of sex differences in behavior.  相似文献   

Disentangling the Respective Contribution of Task Selection and Task Execution to Self-Directed Cognitive Control Development     

Aurélien Frick  Maria A. Brandimonte  Nicolas Chevalier 《Child development》2021,92(4):1309-1324

Task selection and task execution are key constructs in cognitive control development. Yet, little is known about how separable they are and how each contributes to task switching performance. Here, 60 4- to 5-year olds, 60 7- to 8-year olds, and 60 10- to 11-year olds children completed the double registration procedure, which dissociates these two processes. Task selection yielded both mixing and switch costs, especially in younger children, and task execution mostly yielded switch costs at all ages, suggesting that task selection is costlier than task execution. Moreover, both task selection and execution varied with task self-directedness (i.e., to what extent the task is driven by external aids) demands. Whereas task selection and task execution are dissociated regarding performance costs, they nevertheless both contribute to self-directed control.  相似文献

Training effects on contrafreeloading in rats housed in operant chambers     

Robert D. Tarte  Charles T. Rasmussen 《Learning & behavior》1979,7(1):69-74

Four rats were trained to press a bar for food pellets and then were housed in operant chambers for 6 continuous days of choice-testing between obtaining pellets freely or by barpressing. There were two additional 3-day choice periods following more barpress training. It was found that (1) animals preferred to secure food by barpressing when initially placed in the choice situation and immediately following additional barpress training; (2) there was a subsequent decrease to very low levels of response-dependent food taken during choice testing; and (3) opening the chambers for daily maintenance during choice-testing caused a temporary increase in barpressing for food. Thus the previously reported stability of high rates of barpressing in the presence of free food is, at least in part, dependent upon short testing sessions.  相似文献   

Effective Cost-Sharing Models in Higher Education: Insights from Low-Income Students in Australian Universities     

Christopher James Rasmussen 《Higher Education》2006,51(1):1-25

This study examines the global trend in shifting university costs from national governments to individual students and families, with a specific focus on the existing cost-sharing model in Australian higher education. The research examines the manner in which the availability of income-contingent loans (through the Higher Education Contribution Scheme, or HECS) enters into individual cost assessments and evaluative frameworks during the university exploration and search process of low-income Australian youth, and the resulting lessons that might be applied to other national contexts. Semi-structured interviews with 16 participants addressed a broad range of issues related to the development of educational aspirations, and how beliefs and attitudes about cost influenced participants’ understanding and decision-making regarding tertiary enrollment and post-graduate plans. A number of discreet and related themes emerged from analysis of the interviews, including motivations for attending university; pre-university cost considerations; self-assessments of skills, abilities, and personal traits and characteristics; general financial orientation; pre-university experiences and influences; and the role of others including family, peers, teachers and other school staff. The author concludes that the Australian system is worthy of consideration by other nations as a possible mechanism for enhancing access to higher education for individuals who might otherwise not possess the opportunity to participate.  相似文献

Processus de preuve et situations de validation   总被引：2，自引：0，他引：2  

Nicolas Balacheff 《Educational Studies in Mathematics》1987,18(2):147-176

Résumé Nous étudions les relations entre preuves et contradictions dans la résolution d'un probleme de mathématiques. Cette étude montre la nécessité d'une approche à la fois situationnelle et cognitive, notamment en référence au fonctionnement des connaissances dans l'apprentissage des mathématiques. Ceci nous conduit à distinguer différents stades dans l'évolution des preuves pragmatiques aux preuves intellectuelles. Enfin nous montrons que le dépassement d'une contradiction ne constitue pas nécessairement un progrés cognitif, en particulier nous examinons le traitement d'un contre-exemple par des élèves de quatrième.

Proving processes and situations for validation

A study is made of the relationship between Proofs and Contradictions in mathematics problem-solving. With respect to mathematics learning, we show the necessity for an approach being both situational and cognitive. This study leads to the demarcation of several stages from Pragmatic Proofs to Intellectual Proofs. We then go on to show that overcoming a contradiction does not necessarily constitute cognitive progress. In particular we examine how pupils (13–14 year old) cope with counterexamples.

Cultural Differences in Garnering Social Capital on Facebook: French People Prefer Close Ties and Americans Prefer Distant Ties     

Genavee Brown  Nicolas Michinov 《Journal of Intercultural Communication Research》2017,46(6):579-593

The link between social capital (SC) and Facebook has been widely studied in the U.S., and less is known about how students from different cultures use the site to garner SC. We measured network composition, communication on Facebook, and SC via questionnaires in France and the U.S. We found that American students have a greater proportion of distant to close ties in their networks and higher levels of bridging SC than French, the latter preferring bonding SC. A stronger relationship between SC and communication via Facebook was observed in the U.S. These findings are explained by cultural differences in relatedness.  相似文献
