Concreteness
具体性（Concreteness），指材料或表征与具体、可触实例的接近程度；在 TUI 与学习研究中常与抽象性（abstractness）对照。
English Definition
"The degree to which a material or representation is tied to specific, tangible instances versus abstract or symbolic content; in TUI/learning research, often contrasted with abstractness."
用法说明 · 针对中文母语者
在 TUI 设计中是一个常被讨论的设计维度。注意具体性高的材料未必带来更好的学习效果——研究表明抽象材料可能更有利于知识迁移。
常见错误
- ·误以为 concrete = physical——本文明确指出 concreteness effects 与 physicality 应分别处理
- ·把 concreteness 译为'具体性'虽可，但易与日常意义上的'具体'混淆；此处的具体性特指材料/表征在抽象-具体连续体上的位置

"## (v) Concreteness and sensori-directness — When considering the benefits of interacting with physical materials in learning, the effects of the concreteness are often conflated with the physicality of the materials."
"We suggest that concreteness effects should be treated separately."
"While concrete materials can lead to better task performance, abstract materials can lead to better knowledge transfer."
"The question of what combination of concrete and abstract materials should be used in tangible interface design remains an empirical question."
