“…Inhibitory abilities undergo an extremely slow, protracted developmental progression, not reaching full maturity until early adulthood (Diamond, 2002). Thus, for example, in the directed forgetting paradigm (in which participants are directed to forget some words they are shown and to remember others), even 11year-olds show more intrusions of the to-be-forgotten words than do adults (e.g., Harnishfeger & Pope, 1996;Lehman et al, 2000). Similarly, on the "anti-saccade" task (in which participants are instructed to look away in the opposite direction from a visual stimulus, suppressing the tendency to reflexively look at [saccade to] the stimulus), performance improves continuously from early childhood through 20 -25 years of age (Fischer, Biscaldi, & Gezeck, 1997;Luna et al, 2001;Munoz, Broughton, Goldring, & Armstrong, 1998).…”
