The influence of amount and type of exploratory activity upon 3 male and 5 female undergraduates' ability to detect the symmaterical or asymmetrical characteristics of individually presented plastic nonrepresentational shapes was examined. A decrease in scanning time and number of identification errors between the first and fourth days of testing indicates that extended perceptual experience plays a major role in the efficient pick-up and utilization of haptic information. A signal-detection analysis demonstrated that the use of a simultaneous-apprehension scanning strategy resulted in greater sensitivity to asymmetrical shapes than did the use of a simultaneous-apprehension scan. The data support the hypothesis that experience, the form parameter of symmetry, and the type of scanning strategy used to explore a stimulus function together to influence haptic perception of nonrepresentational shapes.
研究了探索活动的数量和类型对3名男性和5名女性本科生检测单独呈现的塑料抽象形状的对称或不对称特征能力的影响。测试的第一天到第四天之间扫描时间和识别错误数量的减少表明，延长的感知体验在有效获取和利用触觉信息方面起主要作用。信号检测分析表明，与使用同时感知扫描相比，使用同时感知扫描策略对不对称形状的敏感性更高。数据支持这样的假设，即经验、对称的形式参数以及用于探索刺激的扫描策略类型共同作用，影响对抽象形状的触觉感知。
