"PERCEP" software for experiment control of temporal judgment research with humans / Programa "PERCEP" para controle experimental de pesquisa em julgamento temporal em humanos

A computer program - "PERCEP" - was developed for accomplishing the experimental procedures of verbal estimation, time production and reproduction in human beings. Besides the collection of data, the program allows the researcher to manipulate different parameters of tasks and to evaluate the impact of those manipulations on acquisition and performance. Once the configuration of the "PERCEP" program is defined by the researcher, a wide range of experiments concerning time judgment processing can take place. The aim of the present work is to describe this program.
