“…If during the C phase, the patient shows a decline in responding as compared to the B phases, one might interpret such decline (i.e., response differentiation) as a sign of discrimination between B and C conditions and presumably a sign of awareness of the instrumental role or absence of role of responding for stimulation access in the two conditions [13,49,52,[66][67][68]84,85,[91][92][93][94]. In psychological terms, such discrimination and awareness could be taken to indicate a learning process and to suggest a patient's nonreflective (pre-reflective) state of basic consciousness or of minimal self-awareness (i.e., awareness of changes occurring in the immediate environment) [66,67,71,[95][96][97]. In essence, patients able to successfully discriminate the C phase from the B phases and differentiate their behavior accordingly could be considered to be in a condition compatible with the minimally conscious state [49,50,91,[98][99][100][101].…”
