Response Bias and Attention in Discriminative Echolocation by Tursiops truncatus
In the Einstellung experiment, stimulus correlated response set or bias can be induced which renders an animal in a maze “functionally blind” to a subsequent simple solution. Until the bias is extinguished, the animal remains insensitive to cues leading to the goal object. Observations on echolocating dolphins suggest that they too may become subject to an Einstellung phenomenon. The present experiment, which grew out of a series of biosonar studies on underwater material discrimination, tested the notion that a response bias acquired in an insolvable discriminative echo-location task will strongly influence the attention of a dolphin on a solvable discriminative echolocation task.
