The current study examined the role redundant amodal properties play in an operant learning task in 3-month-old human infants. Prior studies have suggested that the presence of redundant amodal information facilitates detection and discrimination of amodal properties and potentially functions to influence general learning processes such as associative conditioning. The current study examined how human infants use redundant amodal information (visual and haptic) about the shape of an object to influence learning of an operant response. Infants learned to kick to move a mobile of cylinders while either holding a cylinder, a rectangular cube, or no object. Kick rate served as the dependent measure. The results showed that infants given matching redundant amodal properties (e.g., viewed cylinders while holding a cylinder) showed facilitated operant learning whereas infants given mismatching redundant amodal properties showed inhibited operant learning. These results support and extend the Intersensory Redundancy Hypothesis by demonstrating that amodal redundancy influences complex learning processes such as operant conditioning.
当前的研究考察了冗余非模态属性在 3 个月大的人类婴儿的操作性学习任务中的作用。先前的研究表明，冗余非模态信息的存在有助于检测和区分非模态属性，并可能影响一般的学习过程，如联想条件作用。本研究考察了人类婴儿如何利用物体形状的冗余非模态信息（视觉和触觉）来影响操作性反应的学习。婴儿学习踢动以移动一个圆柱形的移动器，同时握持一个圆柱、一个长方形的立方或不握持任何物体。踢动的频率作为因变量。结果表明，给予匹配的冗余非模态属性（例如，在握持圆柱时观看圆柱）的婴儿表现出促进的操作性学习，而给予不匹配的冗余非模态属性的婴儿则表现出抑制的操作性学习。这些结果支持并扩展了跨感觉冗余假说，表明非模态冗余影响复杂的学习过程，如操作性条件作用。
