“…Participants are required to press a button or produce a linear arm movement timed with the arrival of the moving stimulus at a specified position. Despite the large variety ofexperimental conditions used, research has shown that timing accuracy improves with age, mainly between the ages of 5 and 11 years (Bard, Fleury, Carriere, & Bellec, 1981;Bard et al, 1990;Dorfman, 1977;Dunham, 1977;Fleury & Bard, 1985;Gagnon, Fleury & Bard, 1988;Haywood, 1977Haywood, , 1983Hoffman, Imwold, & Koller, 1983;Shea, Krampitz, Northam, & Ashby, 1982;Stadulis, 1985; Thomas, Gallagher, & Pur- Benguigui and Ripoll vis, 1981;Wade, 1980). Some studies have also demonstrated an Age x Velocity interaction on timing accuracy (Haywood, 1977;Haywood, Greenwald, & Lewis, 1983;Williams, 1985;Wrisberg & Mead, 1983).…”
