The information contained in the input can be determined by the number of binary decisions that need to be made to arrive at the selected stimulus, and the same holds for the response. The task can be described as one of information transmission: The input consists of one out of n possible stimuli, and the output consists of one out of n responses. Performance is nearly perfect up to five or six different stimuli but declines as the number of different stimuli is increased. In a one-dimensional absolute-judgment task, a person is presented with a number of stimuli that vary on one dimension (e.g., 10 different tones varying only in pitch) and responds to each stimulus with a corresponding response (learned before). In his article, Miller discussed a coincidence between the limits of one-dimensional absolute judgment and the limits of short-term memory. 2 The "magical number 7" and working memory capacity.
