<p> This research replicated Dunlap, dePerczel, Clarke, Wilson, Wright, and White’s (1994) single-subject ABAB reversal design using choice/no choice conditions with a 3 year-old Native American boy exposed to trauma. The IV consisted of the child being able to select books to be read during story time vs. no choice. The dependent variables consisted of 2 target behaviors impeding his learning in his Head Start classroom: disruptive and aggressive behaviors. Rate of Behavior 1 during Baseline 2 was 10% higher than during Intervention 1, and considerably higher than Baseline 1. During Intervention 2, rate of Behavior 1 was 10% lower than during Baseline 2, but 24% higher than Baseline 1. Therefore, Behavior 1 responded as expected to the 3 final experimental phases, but was unexpectedly low during Baseline 1 due to uncontrollable, extraneous environmental variables. Rate of Behavior 2 during Intervention 1 was 57% lower than during Baseline 1. During Baseline 2, rate of Behavior 2 was 50% higher than Intervention 1. During Intervention 2, rate of Behavior 2 was 43% below Baseline 1 but 40% higher than Baseline 2. Because occurrence rates for Behavior 2 were low, often 0-3 per session, minor changes in occurrences inflated change percentages. In essence, Behavior 2 improved substantially between Baseline 1 and Intervention 1, then remained stable at low rates across the remaining study phases. During Intervention 2, half the sessions had 0 occurrence rates for Behavior 2, spiking in the final 2 sessions due to an uncontrollable extraneous variable. Overall results appear promising. Future research, with greater observation times and control of extraneous variables, is needed to fully demonstrate intervention effectiveness with young Native American children exposed to trauma. </p><p>
