Frequency of nightmares and gender significantly predict distressing dreams of German athletes before competitions or games

Important sports events are highlights and stressful situations in every athlete's career. This stress might alter the dream content of athletes and consequently evoke disturbed dreaming. In this study, the authors asked 840 German athletes from various sports about distressing dreams on the nights before an important competition or game. About 15% of the athletes stated that they experienced at least 1 distressing dream before an important competition or game during the preceding 12 months. An almost equal number of athletes reported at least 1 distressing dream in their sports career. With respect to the base rate, in about 3% of the events a distressing dream occurred. Reported dream content referred mainly to athletic failure. The main risk factor for an athlete experiencing a distressing dream before a competition appears to be the frequency of experienced nightmares in general. Future research should use diary techniques to study the impact of distressing dreams on the next-day athletic performance in a competition or game.     

Young children share the spoils after collaboration

Egalitarian behavior is considered to be a species-typical component of human cooperation. Human adults tend to share resources equally, even if they have the opportunity to keep a larger portion for themselves. Recent experiments have suggested that this tendency emerges fairly late in human ontogeny, not before 6 or 7 years of age. Here we show that 3-year-old children share mostly equally with a peer after they have worked together actively to obtain rewards in a collaboration task, even when those rewards could easily be monopolized. These findings contrast with previous findings from a similar experiment with chimpanzees, who tended to monopolize resources whenever they could. The potentially species-unique tendency of humans to share equally emerges early in ontogeny, perhaps originating in collaborative interactions among peers.     

Semantics for existential graphs

This paper examines Charles Peirce's graphical notation for first-order logic with identity. The notation forms a part of his system of existential graphs, which Peirce considered to be his best work in logic. In this paper a Tarskian semantics is provided for the graphical system.

“Girls Can’t Play Ball”: Feminist Counseling Using A League of Their Own

This commentary reviews A League of Their Own, a film that provides a fictional account of the lives of women who played in the first year of the All-American Girls’ Baseball League. Set during World War II-era America, the film offers a look into the gendered lives of women seeking careers in traditionally masculine fields. The authors review the movie from a feminist media lens, with specific emphasis on how the two main characters, Dottie and Kit, ascribe to and defy gender stereotypes and gain voice and agency. Specific implications are pulled from the analysis to be used in the context of counseling women, including empowerment of female clients and establishing career identity.
