“…Other experimenters studied age-related changes in perceptual processes (Ridenour, 1974;Williams & DeOreo, 1980), factors affecting decision-making, such as response selection and programming processes (Fairweather & Hutt, 1978;Hay, 1979), memory (Thomas, 1980) or schema formation (Kelso & Norman, 1978). Still, others addressed what are typically motor learning mechanisms such as the ability to process feedback across ages (e.g., Newell & Kennedy, 1978;Thomas, Mitchell, & Solomon, 1979). In this period, researchers studied how children's perceptual-cognitive processes, that were assumed to control movement, changed as a function of age during childhood.…”
