Table 4 Subjects’ performance in Experiment 3, with columns showing, in order: number of correct choices for the continuous string (Bayesian binomial test values in parentheses), number of times subjects first made a correct choice and then switched to the incorrect choice (counted as correct and ended the trial), number of times subjects made the incorrect choice and then switched to the correct choice (counted as incorrect and ended the trial), number of times subjects did not fully retrieve the chosen string from the apparatus, and average time spent interacting with strings.

From: Kea (Nestor notabilis) fail a loose-string connectivity task
