在发展生态声学领域的理论框架时，Gaver（1993 b）区分了音乐听觉（感知声音）和日常听觉（感知声音来源）。在日常的听觉体验中，Gaver（1993 a）提出，物体的频率是由物体的大小决定的。频率和物体大小彼此之间的关系是一个命名映射的例子。符号映射涉及不相关维度的配对，相对于命名映射，需要额外的识别和学习步骤。采用知觉识别任务，实验研究了命名映射比符号映射更容易识别的假设。据预测，这种优势只体现在日常的听力体验，最初的上级识别的nomic映射等同于符号映射后，延长曝光。研究结果支持了上述假设。讨论了命名映射和符号映射的差分识别的理论意义，以及命名关系的实际应用。
In developing a theoretical framework for the field of ecological acoustics, Gaver (1993b) distinguished between the experience of musical listening (perceiving sounds) and everyday listening (perceiving sources of sounds). Within the everyday listening experience, Gaver (1993a) proposed that the frequency of an object results from, and therefore specifies, the size of that object. The relation in which frequency and object size stand to one another is an example of a nomic mapping. A symbolic mapping involves the pairing of unrelated dimensions and, relative to a nomic mapping, requires an additional step in recognition and learning. Using a perceptual identification task, an experiment investigated the hypothesis that nomic mappings are identified more easily than symbolic mappings. It was predicted that the advantage manifests only during the everyday listening experience, and that the initially superior recognition of nomic mappings is equaled by symbolic mappings after extended exposure. The results provided support for the hypotheses. Theoretical implications of the differential recognition of nomic and symbolic mappings are discussed, together with practical applications of nomic relations.
