If you are one of those people who finds it difficult to multitask (I am one of those), you might appreciate this story involving court reporters. I work as a lawyer during the day, and quite often I need to take depositions, which are reported in real time by court reporters who use a special keyboard to take down every word of the deposition. The best court reporters are truly incredible to watch. To be a court reporter, you need to take down at least 200 words per minute without mistakes. You would think that trying to take down every word spoken by everyone in a room would completely occupy your working memory, but good court reporters can do their work proficiently with mental processing capacity to spare. Last week I spent an entire day taking depositions. After the depositions were finished, I asked the court reporter what she was daydreaming about. She smiled, because she knows that experienced court reporters are perfectly capable of daydreaming about such things as grocery shopping or going to the beach at the same time that they are taking down every syllable of every word spoken in the room. I asked this particular court reporter how often she has to go back and look at her transcript to see what was being said, because she was thinking about something else at the time she was taking down the testimony. She told me that she was once working for a judge who was going to sentence a man convicted of murder. The big question that day was whether the man would be put to death or whether he would get a life sentence. This court reporter was assigned to preserve all of the court proceedings regarding this momentous sentencing. After she was done taking down the testimony, and after she left the courtroom, someone asked her whether the judge sentenced the accused to death. This woman hesitated before replying that she did not know, even though she was a court reporter. To find out, she went back to her tape (the strip of paper on which the court reporter's keyboard prints out the testimony), and looked for the critical part. She found out that the judge had actually sentenced the man to death, but she had no memory of this. I asked her whether she is ever asked to read back testimony during a court proceeding or deposition at a time where she became nervous that she might not have been accurately taking down the testimony. She stated that this never happens, and that she is always confident that she's taking down the testimony accurately. If something starts going wrong, her full consciousness kicks in and she deals with the unusual situation fully aware. She has never been caught not taking down the testimony accurately. I find it pretty amazing that someone could have their working memory so thoroughly occupied in the linguistic sense, and yet be able to think about other things. It's even more amazing that when the court reporters daydream or think, they are often doubly-employing their linguistic abilities. It just seems like this would be impossible, but it's commonplace. Most of the court reporters today use a special stenographic keyboard, but there are a few who speak into something that looks like a muzzle. They hear the testimony in the courtroom with their own ears and simultaneously speak those words into this muzzle-device which is recorded by a tape recorder. In short, they "shadow" the testimony with their own voice. Later, someone types out that the court reporter's words into a transcript. I've spoken to some of these muzzle-device court reporters over the years, and they to tell me that they are able to think about other things were daydream while they are taking down the testimony. If you are wondering why we even have court reporters, that would be a good question. The main advantage is that when you have a court reporter, you have a person who is in a position to swear to the accuracy of the transcript, indicating who said exactly what. A tape recorder would simply record the sounds, and might not accurately pick up the exact words that were being spoken (for instance, because someone is mumbling or gesturing). When these sorts of things happen at a deposition, human court reporters ask the witness to speak up or to state their testimony in words rather than gesturing. This makes for a more accurate and more readable transcript. That said, some courtrooms are now employing tape recorders in lieu of court reporters.
