abstract：:This experiment examined the hypothesis that aging reduces the coupling between system components, resulting in a loss of complexity in behavior. Young (18-23 years), old (60-65 years), and older old (70-75 years) subjects performed rhythmical movement and postural tasks with the index finger. Irregularity of the acce...
