Abstract/OtherAbstract:
|
The double-pulse resolution (DPR) measures the processing performance for transient visual signals as the threshold duration for detecting a temporal gap between two light flashes in relation to gap duration. The DPR of four European starlings (Sturnus vulgaris) and four humans was measured in an operant Go/NoGo procedure. We applied the method of constant stimuli and determined thresholds using signal-detection theory. The starling DPR (22.2 ms±2.3 ms SE) was significantly shorter than human DPR (35.2 ms±1.3 ms SE; p<0.01, t-test). The difference suggests that starlings have a higher temporal resolution for transient visual signals than humans. |
