The purpose of memory (STM) training in interpreting is to achieve a better understanding of the source language, which will lead to adequate interpreting. As Lin Yuru et al. put it, "Memory in consecutive interpreting consists of nothing more than understanding the meaning, which is conveyed by the words" (Lin et al., 1999:9). Understanding is the first step in successful interpreting; therefore, memory training is to be provided in the early stage of interpreter training. Memory functions different in consecutive and simultaneous interpreting, because the duration of memory is longer in CI than in SI. There are different methods of training STM for CI and SI respectively. Interpreting starts with the encoding of the information from the original speaker. According to Gile's Effort Model, interpreting is an STM-centered activity; the process of interpreting could be re-postulated into: Encoding of information from the Source Language + Storing Information + Retried of Information + Decoding Information into the Target language.
