In general terms, how does the enhanced cognitive interview differ from the original cognitive ...

•   The enhanced cognitive interview includes all the memory retrieval techniques recommended for use in the cognitive interview, but in addition, the enhanced cognitive interview also includes various principles of social dynamics.
•   Techniques specific to the enhanced cognitive interview:
a.   Rapport building: The officer should spend time building rapport with the witness, making sure they are comfortable, feel at ease, etc.
b.   Supportive interviewer behaviour: The officer should not interrupt the free recall process and should be attentive to what the witness is saying.
c.   Transfer of control: The witness should be the one to control the flow of the interview.
d.   Focused retrieval: As much as possible, questions should be open-ended, non-leading, and non-suggestive.
e.   Witness-compatible questioning: The officer’s questions should match the witness’s line of thought (i.e., if the witness is talking about the culprit’s appearance, the officer’s questions should match this topic).
