We manipulated contextual information in order to examine the perceptual-cognitive processes that support anticipation using a simulated cricket-batting task. Skilled (N= 10) and less skilled (N= 10) cricket batters responded to video simulations of opponents bowling a cricket ball under high and low contextual information conditions. Skilled batters were more accurate, demonstrated more effective search behaviours, and provided more detailed verbal reports of thinking. Moreover, when they viewed their opponent multiple times (high context), they reduced their mean fixation time. All batters improved performance and altered thought processes when in the high context, compared to when they responded to their opponent without previously seeing them bowl (low context). Findings illustrate how context influences performance and the search for relevant information when engaging in a dynamic, time-constrained task.
我们操纵上下文信息,以使用模拟板球击球任务来检查支持预期的感知认知过程。熟练(N=10)和不熟练(N=10)的板球击球手对高和低上下文信息条件下对手投球的视频模拟做出反应。熟练的击球手更准确,表现出更有效的搜索行为,并提供更详细的思维口头报告。此外,当他们多次观看对手(高语境)时,他们会减少平均注视时间。与在低语境下不看对手投球时相比,所有击球手在高语境下的表现都有所提高,思维过程也发生了变化。研究结果表明,当从事一项动态、时间受限的任务时,上下文信息如何影响表现和搜索相关信息。
