Past research has shown that when given a simultaneous visual-discrimination midsession reversal task, pigeons typically anticipate the reversal well before it occurs and perseverate after it occurs. It appears that they use the estimation of time (or trial number) into the session, rather than (or in addition to) the more reliable cue, the outcome from the(More)
Undergraduate teaching evaluations are widely believed to be biased. We analyzed the evaluations from our department for all classes from 2000 through 2008, looking for specific biases. We looked for correlations between evaluation numbers and whether the course was required; how much time students spent on the course; student classification (freshman,(More)
Pigeons given a simultaneous spatial discrimination reversal, in which a single reversal occurs at the midpoint of each session, consistently show anticipation prior to the reversal as well as perseveration after the reversal, suggesting that they use a less effective cue (time or trial number into the session) than what would be optimal to maximize(More)
