Understanding the psychological and neuroscientific roots of interactions between emotion and value requires dissociating and quantifying specific processes contributing to both. Doing so illustrates that affect can interact with value computation in as many ways as there are dimensions of each. Additionally, an overlapping neural circuitry, including the amygdala, insula, striatum, and ventromedial and dorsolateral prefrontal cortex, has been implicated both in the integration of affect with decision-making and in decision-making more generally, suggesting that emotion and value are fundamentally intertwined. Finally, affect is best characterized as modulating decision processes and mechanisms in context-sensitive ways. Because affect and decision-making are not monolithic or even entirely separable, a single, simple relationship between them cannot be expected. Rather, a more nuanced approach that leverages our growing knowledge of the processes and mechanisms underlying both affective phenomena and decision-making is needed to understand the specific ways in which affect interacts with value.
