WebJul 4, 2024 · As we learn to interiorize social reward and satisfaction, we also develop the ability to stimulate an intrinsic motivation with a cortical (‘central’) arousal which leads, at the autonomic level, to a tendency to co-activate the SNS and the PNS facing socially rewarding or challenging stimuli [43,44]. This will have the resulting function ...
