The hypothesis, which is an extension of Hull's goal reaction hypothesis, is that the goal reaction gets conditioned most strongly to the stimuli preceding it, and the other reactions in the sequence get conditioned to their stimuli, with a strength inversely proportional to their temporal or spatial remoteness from the goal reaction. Since this assumes a gradient, which is related to the goal, he calls it a goal-gradient. The shape of this gradient is shown, by reference to Yoshioka's experiment in selection of maze pathways by the rat, to be positively accelerated, and to conform to the logarithmic law. The author deduces ten actual behavior phenomena from his principle, such as choice of shorter path, order of elimination of blind alleys, relative rates of locomotion in different parts of the maze, etc.
