A History of Psychology - routledgetextbooks.comOne might also hypothesize that a unifying feature of this area might be the notion that this area is representing some kind of value-related signal in each of these contexts.Del Casale A, Kotzalidis GD, Rapinesi C, Serata D, Ambrosi E, Simonetti A, Pompili M, Ferracuti S, Tatarelli R, Girardi P.Philip David Zelazo (born 1966) is a developmental psychologist and neuroscientist. His research has helped shape the field of developmental cognitive neuroscience.
Given that higher anatomical resolution causal studies will be required to relate activation in these brain areas to specific functions.In as much as our choices are consistent and lawful, the brain must represent the values of many different kinds of rewards on a common scale for comparison and choice.However, in all of these studies only a single reward type and a single task-type was used to examine the neural representation of value.
Indeed, there is now broad consensus in the neuroscience of decision-making community that reward magnitude is represented in a small number of well-identified areas.

Perhaps even more exciting is the possibility that our emerging understanding of the neural mechanisms for valuation and choice may provide fundamental insights into pathological choice behaviors like addiction, obesity and gambling.University of Lethbridge.
