Perceptual dependence--the existence of perceptual interactions between the component dimensions of the same stimulus--was investigated for shape and texture during haptic processing. The haptic system combines tactual and kinesthetic information. Previous research has demonstrated that haptic exploration influences the extent to which object properties are integrated. Conditions designed to promote and impede the integration of shape and texture were compared. Perceptual independence was assessed by the use of a speeded-classification paradigm and quantitative tests developed by Ashby and Maddox. Results indicate that shape and texture are perceptually dependent for both conditions. Hand-movement analysis show simultaneous exploration for both dimensions. The tendency to process dimensions dependently is discussed in terms of a limited-capacity model of haptic-information processing.
知觉依赖性——同一刺激的组成维度之间存在知觉交互作用——在触觉加工过程中针对形状和质地进行了研究。触觉系统整合了触觉和动觉信息。先前的研究表明，触觉探索会影响物体属性整合的程度。比较了旨在促进和阻碍形状与质地整合的条件。通过使用快速分类范式以及由阿什比和马多克斯开发的定量测试来评估知觉独立性。结果表明，在两种条件下形状和质地在知觉上都是相互依赖的。手部运动分析显示对两个维度同时进行探索。根据触觉信息加工的有限容量模型讨论了维度依赖性加工的倾向。
