Recent evidence is reviewed to examine relations among sensory, sensorimotor, and cognitive aging. Age-heterogeneous cross-sectional data sets show substantial covariation among sensory, sensorimotor and intellectual abilities, and an increase in covariation from adulthood to old and very old age. Recent longitudinal analyses suggest that changes in sensory and intellectual functioning are interrelated. Experimental studies investigate the interdependence between cognitive and sensory/sensorimotor aging by examining the effects of simulated sensory loss on cognitive performance, or the effects of cognitive load manipulations on sensory or motor performance. Generally, both types of manipulations hinder older adults' performance more than that of younger adults. Theoretically, the age-associated intensification of the links among sensory, sensorimotor and cognitive functions observed both correlationally and experimentally may point to (a). common causes influencing all three functions; (b). an increase in resource overlap, cross-domain resource competition, and compensatory tradeoffs; and (c). a combination of the two. Future research aiming at discerning the relative import of these possibilities would profit from an integration of experimental and correlational research strategies.

UI	MeSH Term	Description	Entries
D009068	Movement	The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior.	Movements
D009069	Movement Disorders	Syndromes which feature DYSKINESIAS as a cardinal manifestation of the disease process. Included in this category are degenerative, hereditary, post-infectious, medication-induced, post-inflammatory, and post-traumatic conditions.

D011597	Psychomotor Performance	The coordination of a sensory or ideational (cognitive) process and a motor activity.

D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon

D000375	Aging	The gradual irreversible changes in structure and function of an organism that occur as a result of the passage of time.	Senescence,Aging, Biological,Biological Aging
D012677	Sensation	The process in which specialized SENSORY RECEPTOR CELLS transduce peripheral stimuli (physical or chemical) into NERVE IMPULSES which are then transmitted to the various sensory centers in the CENTRAL NERVOUS SYSTEM.

D012678	Sensation Disorders	Disorders of the special senses (i.e., VISION; HEARING; TASTE; and SMELL) or somatosensory system (i.e., afferent components of the PERIPHERAL NERVOUS SYSTEM).
