Comments
(1) Simultaneous mode of interpreting is used when the recipients of interpretation are listening or watching, and the flow of information is in one direction only, such as during trials, motion hearings and classes.
(2) Research has established that simultaneous interpreting involves intensive cognitive activity. Interpreter fatigue-both physical and mental-results from the high degree of concentration an interpreter must employ to hear, analyze, and understand ideas in one language and then render those same ideas coherently in another. This research has demonstrated that accuracy begins to decline within 15 to 30 minutes of simultaneous interpreting, before interpreters are even aware of the fatigue that leads to this increase in errors. After 30 minutes, the decline is precipitous. Therefore, it is imperative that interpreters alternate every 15 to 30 minutes, as agreed upon by members of the interpreting team.
(3) Consecutive mode of interpreting is used when the recipients of interpretation are responding to questions and the exchange of information is two-directional, such as during testimony, interviews, and depositions.
(4) In consecutive mode, the interpreter must focus intensely to memorize substantial chunks of information and then render them precisely.
Consecutive mode requires the same amount of cognitive work as simultaneous, but the fatigue builds up over a longer period of time.
(5) Communication through sign language can be particularly broad and challenging. Not all Deaf, Deafblind, or hard of hearing participants use the same sign language dialect, and some have specialized linguistic needs. A Deaf Interpreter (DI) may be needed in addition to an ASL interpreter. A DI is a professional interpreter who is Deaf, an expert in ASL linguistics, and a native user of ASL. These skills uniquely qualify them to meet the linguistic and cultural needs of a Deaf person. The requester should look to the expertise of the sign language interpreter and the knowledge and experience of the parties to identify such needs and assign a team of sign language interpreters where appropriate.
