Column numbers are enclosed in parentheses. Columns 1 and 2, respectively, identify the bird and the experimental condition. Columns 3 and 4 present the response rate in responses/min during the green and red components for P3 and P4, respectively, and the yellow and green components for P5 and P6, respectively. These are the component rates prior to the arrival of the good-news or bad-news stimulus. Columns 5 and 6 are the same as 3 and 4 except for the predictive value of the two cuing stimuli. For columns 3 and 4, the designation “Good news>Bad news” means that the cue in the good-news component is more informative than the cue in the bad-news component. For columns 5 and 6, this designation is reversed.
