In a learning experiment a researcher ran rats through a maze  Some of the rats were blind, others deaf, others lacked a sense of smell, and others had no sensory deficiencies; yet all the rats learned the task in much the same amount of time  Of the senses other than sight, hearing, and smell, only kinesthesia had not previously been shown to be irrelevant to maze-learning
The researcher concluded on the basis of these facts that kinesthesia, the sensation of bodily movement, is sufficient for maze-learning
It can be determined from the data that maze-learning in rats depends on at least two sources of sensory stimulation, one of which is kinesthesia, but which of the remaining sources must also be employed is not determinable.
