Final answer:
The incorrect statement about semantic distance is that it is compatible with Classical Theory, as semantic distance implies a more flexible relationship between concepts that Classical Theory does not accommodate.
Step-by-step explanation:
Semantic distance represents the relatedness or conceptual distance between two ideas or concepts within a semantic network. When considering what is not true about semantic distance, option C, which suggests that semantic distance is compatible with Classical Theory, can be identified as the incorrect statement. Classical Theory suggests that concepts are understood by a fixed set of features, which does not account for the variability and flexibility provided by semantic distance.
Spreading activation is a process described within a semantic network, indicating that when one concept is activated, related concepts are also activated to a degree, making it easier to retrieve associated information. This demonstrates how semantic distance can be informative about how we store and retrieve knowledge in a web of concepts. Moreover, semantic distance aligns with the Theory-Theory idea, which posits that our understanding of concepts is informed by our theories about the world rather than by a strict set of defining features.
