An algorithm comparing the two mononuclear curves of choice reaction times in pigeons

A simple and fast algorithm allowing the matching between frequency distributions is developed. The procedure consists in a class by class mapping of two distributional curves in order to derive a class transformation function that specifies how a class from one distribution is modified to produce a class in another distribution. Being interested in investigating the equivalence between the eyes, we have compared left and right monocular curves of choice reaction times to three different visual discrimination tasks in intact and surgically manipulated pigeons by means of the present technique of analysis. The results indicate that RTs distributions of the eyes belong to the same family of functions. It is possible, however, to demonstrate a difference in the range of time responses between the two monocular curves during one of the three visual discriminations used, particularly in the lesioned group.
