A series of behaviors suggesting deficient response inhibition is also seen following developmental Pb exposure. Specific behavioral deficits are seen on tests of passive avoidance, one way active avoidance, differentied reinforcement of low rates of responding (DHL-EO)" and fixed interval schedules of operant controlled behavior operant extinction and operant response inhibition, spontaneous cdternation," "" and various discrimination reversal problems " "" have also been observed following developmental Pb exposure. [Pg.102]

Figure 1 IRT absolute frequency distribution for one session of a fixed interval schedule for control (top) and monkeys exposed to 500/zg/kg per day of lead (bottom). The divisions along the abscissa represent classes of time between successive responses, in 100 ms increments. The lead-treated monkeys in general had a much higher absolute frequency of IRTs and a distribution skewed towards shorter IRTs...

Figure 10 The proportion of IRTs l.Os for individual control (left) and 25 ppm lead-acetate treated rats (right) over the first 40 experimental sessions on a fixed-interval food reinforcement schedule. The experiment was replicated twice. The results of the first replicate are shown in the top panels, the second replicate in the bottom panels. Each curve is from an individual rat, each data point represents a median value for five sessions (Cory-Slechta et al, 1985)...
