摘要：

In Why Consciousness, Aumann (2024) argues that consciousness evolved to enable the experience of incentives while leaving open the question of “How” which we address by relying on brain plasticity at the synaptic level. We hypothesize that the experience of incentive emerges from the modulation of synaptic plasticity respectively by the gain-oriented dopamine and loss-oriented serotonin neuromodulators which together with acetylcholine and norepinephrine, modulating top-down attention and bottom-up salience, yields a sensory component reference-dependent and context-sensitive model of decision making, encompassing a broad range of choice phenomena. As an application, we generalize Karni and Vier?’s (2013) choice model from increasing awareness to changing awareness.
