Binocular interactions measured by choice reaction times in pigeons.
In 7 pigeons binocular interactions were studied by recording monocular and binocular choice reaction times (RTs) to a pattern discrimination task. In all the animals binocular responses were found to be significantly faster than monocular RTs. In order to assess whether binocular advantage might be ascribed to a neural interaction between the two eyes, monocular and binocular performances were evaluated according to a probability summation model. The results indicate that in the great majority of animals, probability summation alone can account for binocular superiority.
