let me repeat what happened. i coded everything. then [a research assistant] coded all the trials highlighted in yellow. we only had one trial that didn’t agree. i then mistakenly told [another research assistant] to look at column B when he should have looked at column D. … we need to resolve this because i am not sure why we are going in circles.” … The gist of the information is that, as appropriate to good practice, the protocol was originally designed to blind (or deafen) coders to the monkeys’ stimulus, so that the coder would merely observe a monkey in each trial, with the sound off and no knowledge of which pattern was being played, and score the monkey’s changes in behavior.
