Congruency effects are taken as evidence that semantic information can be processed automatically. However, these effects are often weak, and the straightforward association between primes and targets can exaggerate congruency effects. To address these problems, a mouse movement method is applied to scrutinize congruency effects. In one experiment, participants judged whether two numbers were the same ("3\3") or different ("3\5"), preceded by briefly presented pictures with either positive or negative connotations. Participants indicated their responses by clicking a "Same" or "Different" button on the computer screen, while their cursor trajectories were recorded for each trial. The trajectory data revealed greater deviation to unselected buttons in incongruent trials (e.g., "3\5" preceded by a green traffic light picture). This effect was influenced by the type of responses but not by prime durations. We suggest that the mouse movement method can complement the reaction time to study masked semantic priming.
一致性效应被视为语义信息可以自动处理的证据。然而，这些效应往往很微弱，并且启动刺激与目标刺激之间的直接关联可能会夸大一致性效应。为了解决这些问题，一种鼠标移动方法被用于仔细研究一致性效应。在一项实验中，参与者判断两个数字是否相同（“3\3”）或不同（“3\5”），在这之前会短暂呈现具有积极或消极内涵的图片。参与者通过点击计算机屏幕上的“相同”或“不同”按钮来表明他们的回答，同时记录他们每次试验的光标轨迹。轨迹数据显示，在不一致的试验中（例如，绿色交通信号灯图片之前的“3\5”），对未选择按钮的偏差更大。这种效应受反应类型的影响，但不受启动刺激持续时间的影响。我们认为，鼠标移动方法可以补充反应时间来研究掩蔽语义启动。
