This field study examined the influence of a pre-game imagery intervention implemented by a high school coach on the free throw shooting performance of his girls' basketball team. The coach conducted a systematic guided imagery exercise prior to half of the team's games over the course of an entire season. The coach employed the intervention with the whole team using a reversal design similar to the replication-reversal design used in some single-subject research (Hume, Martin, Gonzalez, Cracklen, & Genthon, 1985). A 2 x 2 chi-square analysis was used to evaluate the observed and expected frequencies of made and missed free throw shots under the two conditions (imagery and no-imagery). The results revealed a significantly higher than expected number of free throws made in games preceded by the intervention (p < .001). Social validation questionnaires completed by 11 of the 16 players suggested that the players devoted significant attention to the intervention and that they perceived it to be effective.
Blepharochalasis is a rare disorder of unknown etiology defined by loose, atrophic periorbital skin following recurrent episodes of eyelid edema. Characteristic histopathology shows complete absence of elastic fibers. The current case progressed after multiple episodes of crying, which may be related to matrix metalloproteinase dysregulation. This case offers further insights into the possible pathogenesis of blepharochalasis, paving the way for more targeted, disease-modifying therapies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
