Our capacity to attribute mental states to others, or theory of mind (ToM), affects the way in which we manage social interactions. Likewise, the social scenario in which we find ourselves probably influences our use of ToM. In this study, 6-year-old children and adult women participated in pairs in a task where participants needed to infer their partner’s behavior considering the partner’s visual perception (Experiment 1), knowledge (Experiment 2), and false belief (Experiment 3) regarding the placement of rewards under cups. The results were analyzed according to the temporal direction of the inference (past or future behavior of the partner), the social context (competition or cooperation), and—in the case of women—the type of social relationship with their partner (another adult or their own child). Children solved only the visual perception task, and adults solved the three tasks but performed better in the visual perception task than in the false belief task, suggesting that not only developmental issues but also differences in the intrinsic difficulty of the tasks underlie children’s results. The temporal direction of the inference, in contrast, did not influence their results. Whereas children performed better in the competition context, adults performed better in the cooperation context in one experiment. Moreover, women avoided competing against their own child, and even cooperated with her or him when this was against their own interest, suggesting that cooperation between mothers and children might have been a key driving force in the evolution of ToM in our species.

Aunque existe un bloque de la literatura que estudia la relación entre psicología y lesiones deportivas, los estudios sobre personalidad resistente, ansiedad competitiva y competitividad son muy escasos. Esta revisión sistemática muestra que la información concerniente a estos resulta incompleta y, en ocasiones, es contradictoria. El propósito de este trabajo es revisar la literatura que analiza estos factores psicológicos en las lesiones de los deportistas. Se identificaron estudios significativos a través de una búsqueda sistemática en PubMed y Sport-Discus, extrayéndose datos sobre el dise˜no del estudio, participantes, variables, instrumentos y resultados. Se incluyeron 6 estudios, 2 referentes a personalidad resistente y otros 4 relacionados con ansiedad competitiva, sin encontrar ninguno significativo respecto a competitividad relacionada con lesiones deportivas. La evidencia inicial indica que mayores puntuaciones en personalidad resistente y menores puntuaciones en ansiedad competitiva disminuyen la vulnerabilidad del deportista a padecer lesiones deportivas. Se señalan estadísticamente y se discuten los resultados. Although there is a block of literature that examines the relationship between psychology and sports injuries, studies on hardiness, competitive anxiety and competitiveness are very scarce. This systematic review shows that the information concerning these is incomplete and, at times, contradictory. The purpose of this study is to review the literature that analyzes these psychological factors in the injuries of athletes. It was identified significant studies through a systematic search in PubMed and SportDiscus, extracting data on the design of the study, participants, variables, instruments and outcomes. Six studies were included, 2 benchmarks to hardiness and other 4 related to competitive anxiety, did not find any significant with respect to competitiveness associated with sport injuries. Initial evidence indicates that higher scores in hardiness and lower scores on competitive anxiety decrease the vulnerability of the athlete to suffer sports injuries. Statistically and results are discussed.
