Effects of field-articulation and feedback on perception of intermediate visual-kinesthetic position.

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.
