A key feature of duplic is that it exhibits both point-to-point correspondence (where the stimulus and responseA response is a single occurrence or instance of a behavi...

The Three Forms of Duplic

1. Echoic Duplic
   Echoic duplic is the replicationReplication refers to the process of repeating experiments ... More of verbal utterances that one hears. It involves an auditory verbal discriminative stimulus that prompts the individual to imitate the sound or word they’ve just heard.
   Example: If someone says “cookie,” a person using echoic duplic will respond by saying “cookie,” mirroring the exact vocal response.
2. Mimetic Duplic (Motor Imitation)
   Mimetic duplic focuses on replicating visual verbal stimuli, such as sign language or gestures. In this case, a visual stimulus—like a gesture or sign—prompts the speaker to mirror it. This is often observed in the context of non-verbal communication.
   Example: If someone signs “cookie,” a person skilled in mimetic duplic will accurately reproduce the sign for “cookie.”
3. Copying Text Duplic
   Copying text duplic occurs when an individual replicates written or tactile forms of communication. This form of duplic is guided by a textual verbal discriminative stimulus, such as seeing or feeling a word.
   Example: When presented with the word “cookie” in written form, a person skilled in copying text duplic will reproduce the word by writing it or finger-spelling it.

Why Duplic Matters

Duplic plays a vital role in language development and social interaction, enabling individuals to effectively imitate and replicate verbal stimuli across different sensory modalities. Its three forms—echoic, mimetic, and copying text—highlight the flexibility of duplic in communication, reinforcing the importance of formal similarity and point-to-point correspondence in mastering language.
