We investigated the automaticity of implicit sequence learning by varying perceptual load in a pure perceptual sequence learning paradigm. Participants responded to the randomly changing identity of a target, while the irrelevant target location was structured. In Experiment 1, the target was presented under low or high perceptual load during training, whereas testing occurred without load. Unexpectedly, no sequence learning was observed. In Experiment 2, perceptual load was introduced during the test phase to determine whether load is required to express perceptual knowledge. Learning itself was unaffected by visuospatial demands, but more learning was expressed under high load test conditions. In Experiment 3, we demonstrated that perceptual load is not required for the acquisition of perceptual sequence knowledge. These findings suggest that perceptual load does not mediate the perceptual sequence learning process itself, supporting the automaticity of implicit learning, but is mandatory for the expression of pure perceptual sequence knowledge.
我们通过在纯知觉序列学习范式中改变知觉负荷来研究内隐序列学习的自动性。参与者对目标的随机变化身份做出反应，而目标的位置则是有结构的。在实验 1 中，目标在训练期间处于低或高知觉负荷下呈现，而测试则在没有负荷的情况下进行。出乎意料的是，没有观察到序列学习。在实验 2 中，在测试阶段引入了知觉负荷，以确定是否需要负荷来表达知觉知识。学习本身不受视觉空间需求的影响，但在高负荷测试条件下表现出更多的学习。在实验 3 中，我们证明了获得知觉序列知识不需要知觉负荷。这些发现表明，知觉负荷本身并不介导知觉序列学习过程，支持内隐学习的自动性，但对于纯知觉序列知识的表达是强制性的。
