Cognitive and sensorimotor functioning in aging populations
This thesis investigated specific relations between different executive functions and sensorimotor functions in neurologically and physically healthy adults. The secondary aim of this thesis was to examine potential moderating effects of environmental factors, such as demographics, socioeconomic status, loneliness, social isolation, handedness, and engagement in physical activities. The three main findings are that executive functions declined in participants older than 50 years of age, whereas sensorimotor functions were stable across the adult lifespan until 60+ years of age. Furthermore, no associations were found between environmental factors and executive and motor functions. Findings of the present study will assist in developing targeted interventions and preventative programs prior to cognitive-motor declines.
