Concerning the judgments bias and cue utilization in basketball athletes, previous shot anticipation tasks were hard to examine in regards to whether the experts' judgement bias relies more on the cue of the player's body or the ball trajectory.
Four types of body-ball cues shots were employed: IN-IN, IN-OUT, OUT-IN, and OUT-OUT. Four temporal stages (i.e., shooting, rising, high point, and falling) were divided during a shot. Forty-two participants predicted the fate of the ball after watching the shot videos.
The results suggested that for the shooting, rising, and high point phase, compared to the non-athletes, the experts provided superior predictions for IN-IN condition and OUT-IN condition but fewer accurate predictions for IN-OUT condition and OUT-OUT condition. Moreover, a higher bias toward predicting the shots as "in" for the athletes than the non-athletes under early temporal conditions was confirmed.
These findings strengthen the idea that the IN cues from both body information and ball trajectory could elicit the experts' judgement bias for made shots and then influence their response, thus rendered two distinct (e.g., impeding and facilitating) effects for the incongruent body-ball cues, respectively.
关于篮球运动员的判断偏差和线索利用，以往的投篮预判任务很难考察专家的判断偏差是更多地依赖于球员身体线索还是球的轨迹线索。
采用四种身体-球线索投篮类型：内-内、内-外、外-内和外-外。在一次投篮过程中划分出四个时间阶段（即投篮、上升、最高点和下降）。42名参与者观看投篮视频后预测球的结果。
结果表明，在投篮、上升和最高点阶段，与非运动员相比，专家对“内-内”情况和“外-内”情况的预测更准确，但对“内-外”情况和“外-外”情况的准确预测较少。此外，证实了在早期时间条件下，运动员比非运动员更倾向于将投篮预测为“命中”。
这些发现强化了这样一种观点，即来自身体信息和球轨迹的“内”线索会引发专家对命中投篮的判断偏差，进而影响他们的反应，从而分别对不一致的身体-球线索产生两种不同的（如阻碍和促进）影响。
