7个月大的婴儿，当达到一个物体，视觉引导他们的把握预先定向他们的手，以配合对象的方向。然而，在早期的证据，前瞻性把握控制通过预期的手的方向是混合的。本研究纵向研究了15名婴儿的预期手定向的发展，在5到7.5个月之间每3周观察一次。在每次访问中，婴儿被给予8次垂直和水平方向的物体。在任何触觉反馈之前，第一个接触点的手方向指示婴儿的预期抓握。在5至7个月之间，婴儿表现出的证据，在前瞻性控制的把握，支持的论点，即控制的把握转移的基础上触觉反馈的视觉，因此前瞻性的基础上的质的转变。如何前瞻性把握出现发展的影响进行了讨论。
By 7 months, infants, when reaching for an object, visually guide their grasp by preorienting their hands to match the object's orientation. Evidence at earlier ages, however, for prospective grasp control via anticipatory hand orientation is mixed. This study examined longitudinally the development of anticipatory hand orientation in 15 infants, seen every 3 weeks between 5 and 7.5 months. On each visit, infants were given 8 trials of reaching for an object oriented vertically and horizontally. Hand orientation at the first point of contact, prior to any tactile feedback, indexed infant prospective grasp. Between 5 and 7 months, infants showed evidence for qualitative transition in prospective control of grasp, supporting the contention that control of grasp shifts from being based on tactual feedback to being visually and therefore prospectively based. Implications for how prospective grasp emerges developmen-tally are discussed.
