Abstract	The characteristic slowness of movement initiation and execution in adult individuals with mental retardation may be driven by the slower frequency profile of the dynamics of the system. To investigate this hypothesis, we examined the resting and postural finger tremor frequency profile (single and dual limb) of adults as a function of level of mental retardation (moderate, severe, profound). There was a progressive increase in the contribution of slow frequency components to the enhanced amplitude of tremor as a function of mental retardation, particularly in the group with profound mental retardation. Findings support the hypothesis of mental retardation inducing a slower frequency to the system dynamics that may fundamentally drive the characteristic slowness of movement behavior. (Author).
