The purposes of this investigation were to compare an individual's magnitude and direction of error in three tests of kinesthetic perception, and to determine whether individuals tend generally to reduce, augment, or moderate stimuli on all three tests. A single group design was employed, using a sample of 34 male students. The variables of joint angle reproduction (JAR), muscular tension reproduction, and limb load discrimination were measured in random order for each subject individually by the investigator and one assistant. It was found that the group as a whole was much more accurate at joint angle reproduction and weight discrimination than at muscle tension reproduction; between the two primarily proprioceptive tasks, JAR and muscular tension reproduction, no relationship was found. JAR and muscular tension reproduction appear to be highly specific abilities and depend largely on short-term memory traces. (JB)
