study fonshi heredi (1940) used a selective breeding program to develop separate strains of "smart rats" and "dumb rats". Tryon started with a large sample of lab rats and tested each animal on a maze-learning problem. Based on their error scores for the maze, Tryon selected the brightest rats and the dullest rats from the sample. The brightest males were mated with the brightest females. Similarly, the dullest rats were interbred. This process of testing and selective breeding was continued for several generations until Tryon had established a line of maze-bright rats and a separate line of maze-dull rats. The following data represents results similar to those obtained by Tryon. The data consist of maze-learning error scores for the original sample of lab rats and the seventh generation of maze-bright rats.
