在行为动力学的进化理论中,增强作用以及突变率和选择压力的作用
摘要:A series of screen captures from a computer program that implemented the evolutionary theory. The images show the population of potential behaviors after 0, 10, 20, 30, and 60 generations (or time ticks). Integer phenotypes ranging from 0 through 1023 are represented along the -axes. The relative frequencies of the phenotypes in the population are plotted along the -axes; note that these frequencies may equal zero. The vertical dashed line falls at phenotype 41. During the period of time shown in the figure, phenotypes 0 through 41 constituted a class of behaviors that defined a lever press. Lever presses (any emitted phenotype from 0 through 41) were reinforced on a random-interval schedule. The number of reinforcers delivered by the end of 0, 10, 20, 30, and 60 time ticks is shown on the right
