Abstract: | This study assessed whether a post-coma woman functioning at the lower end of the minimally conscious state would (a) develop
adaptive responding through the use of microswitch technology and contingent stimulation, (b) consolidate and maintain her
responding over time, and (c) show evidence of response-consequences awareness (learning and discrimination). The study involved
an ABABB1CB1 sequence in which the A represented baseline phases, the B and B1 intervention phases, and the C a control phase with continuous stimulation. Results indicated that the woman developed adaptive
responding and consolidated it over the intervention phases of the study. The woman also showed evidence of being aware of
response-consequences links. Potential implications and limitations of these findings are discussed. |
