The location of each A. nemorum was recorded every third minute over a period of 30 min. The 'visitation rate' for each of the four choice zones was defined as 'the number of recorded insect observations in the choice zone divided by the total number of observations'.
Because rats varied in the extent to which they explored the maze, we also analyzed a composite percent correct measure which was the number of correct choices (rewards retrieved) divided by the total number of choices made (the sum of the number of rewards retrieved/reference memory errors, and errors of commission).
The sensation of choice, without the choice: herbed burgers, divided by greaseproof discs, pork loins, chops, fillets, sausages in sixes, chipolatas, beef rumps, brisket tied with string, rissoles, pastrami, sandwich ham with a smiley face running through it like the lettering in a stick of rock.
In all cases, the reward rate was computed as the fraction of correct choices across trials, divided by the average trial time, which is the time between the onsets of consecutive trials.
Data were tabulated based on the number of responses for each choice per individual question divided by the total number of responses for that question.
Perseveration was assessed through models investigating the effect of group, sex, and delay block on time spent nosepoking into the food tray during the choice phase, delay phase (divided by delay experienced), intertrial interval (divided by intertrial interval experienced), and reward collection phase.
The choice divided both congressmen and the city council.
Participants completed 3 practice trials, followed by a total of 90 trials (45 active-choice and 45 no-choice), divided into 3 blocks of 30 trials each.
Item content validity index in stage 2 is the number of expert choices of 3 and 4 divided by the total number of experts.
These means can calculated from the participants' choices when concerning the statements, divided by the total number of quiz takers.
