A new << (..) research confirmed what savvy marketers already know: the longer you look at one of two objects, the more likely you’ll choose that object even if you initially valued the other one more >>
<< (..) dorsomedial prefrontal cortex (PFC) plays a critical role in mediating the balance between prior value assessment and an object’s immediate appeal >>
<< The significance of the dorsomedial PFC came as a surprise because of its relative neglect in the decision neuroscience literature >>
<< Much work on value-based decision-making has focussed rather on the ventral-frontal and orbitofrontal cortex >>
This << findings suggest that, in the healthy brain, the dorsomedial PFC is also important in decision-making, helping to recall the value of objects that are not directly in view so that you can keep your options open >>
<< We’re trying to decompose the different aspects of decision-making. People have this idea that their preferences and value judgments are consistent and rational but, in fact, we’re heavily influenced by factors that are not apparent to us >>
