A bottlenosed dolphin (Tursiops truncatus) was able to
judge whether a second of two visually presented objects was the
“same” as, or “different” from, the preceding
one. She furthermore demonstrated immediate transfer of the “same/different”
rule to novel stimuli. Further tests demonstrated a lack of effect
of duration of exposure of the first object (3, 4, and 7s) or
the duration of delay 93, 10, and 21s) before exposure of the
second object. The dolphin was also able to judge whether a third
visually-presented (probe) object, in a series of three, was the
“same” as either of the preceding two, or “different”
from both. Judgments were as accurate when the first item in the
list matched the probe object as when the second item matched.
