Research output: Contribution to journalReview articlepeer-review


Research studies that fail to recognize the importance of participant age classifications might lead to erroneous conclusions about human behavior. Age is a crucial person variable because of the known physical, perpetual, and cognitive changes accompanying the aging process. Age-related differences in performance can be attributable to factors such as sensory and perceptual changes, movement control differences, cognitive changes, and cohort differences. All these factors may influence human system interactions.
