ABSTRACTThe literature on momentum is still undecided, with mixed results whether momentum exists or is only perceived to exist (“hot hand fallacy”). We explore whether momentum exists by looking at cases in which a basketball player has three consecutive free throws. A free throw is a well-defined task executed in a stable environment, allegedly giving momentum optimal chances to occur. Taking 14 NBA seasons we collected over 4500 three-free-throw sets (triplets). We obtained the outcomes of the shots as well as some additional variables about the player and the game: the player’s average free-throw percentage, home or away, and the game score and the quarter when the free throws were attempted. We first analyse the hit rates in the three shots and then proceed to regression analysis that also controls for the abovementioned variables. We address several concerns raised in the literature. All comparisons and analyses yield the same conclusion that there is no evidence for momentum in the data. 相似文献

Tim Henman was inarguably the best English player, and the most popular and socially significant British player, since Fred Perry. Throughout his career, media constructions of him fluctuated from being heralded as a potential Wimbledon champion, to a weak, underachieving perennial loser. Throughout his career, and despite the constant transition of dominant narratives, Henman’s quintessential ‘Englishness’ remained a key component, expressed through his image, appearance, ostensible personality/character and playing style. His ‘Englishness’ was especially apparent against the backdrop of the Wimbledon Championships, which used Henman’s success in its marketing of ‘tennis in an English garden’. This paper assesses the shifting meanings behind, and values of, Henman’s sustained image, and examines how changes in the narratives of Henman as a player reflected broader shifts in English identity. It is argued that Henman played a significant role in how Englishness was constructed, both in Britain and abroad, during the 1990s and 2000s. 相似文献
