High and low field-articulators were compared on the accuracy with which they could adjust a rod to intermediate visual-kinesthetic positions while blindfolded, under four sensory-feedback conditions. Independent groups of 10 Ss were given auditory, visual, kinesthetic, or no sensory feedback for 16 trials and then tested on 8 trials without sensory feedback. High field-articulators were significantly more accurate on the feedback trials for all sensory-feedback conditions but not in terms of mean absolute error. The mean constant error on the test trials was significantly lower for the high field-articulators on all feedback conditions except for visual feedback where the low field-articulator had a lower constant error. Both the high and low field-articulators became more accurate and learned more in judging visual-kinesthetic position when auditory feedback was given. Low field-articulators showed significant improvement in accuracy with kinesthetic feedback. The results supported the hypothesis that intermediate directions can be learned and supported previous perceptual research.
在四种感觉反馈条件下，对高场发音者和低场发音者在蒙眼时将一根杆调整到中间视觉 - 动觉位置的准确性进行了比较。10名被试组成的独立组在16次试验中分别接受听觉、视觉、动觉或无感觉反馈，然后在8次无感觉反馈的试验中进行测试。在所有感觉反馈条件下的反馈试验中，高场发音者的准确性显著更高，但在平均绝对误差方面并非如此。在测试试验中，除了视觉反馈条件下低场发音者的恒定误差较低外，在所有反馈条件下高场发音者的平均恒定误差显著更低。当给予听觉反馈时，高场发音者和低场发音者在判断视觉 - 动觉位置时都变得更准确且学习得更多。低场发音者在动觉反馈下准确性有显著提高。结果支持了中间方向可以被学习的假设，并支持了先前的知觉研究。
