Simulation of flavour–nutrient conditioning.

Abstract

The lines show the evolution of the learned value of three different flavours with orthogonalized intrinsic sweetness and nutritive values. The red flavour is not sweet but is highly nutritious—and so lacks shaping (as in Fig 1). The green flavour is very sweet (with a shaping function reflecting this) but is not nutritious. The blue flavour is somewhat sweet and somewhat nutritious and is also associated with a perfect shaping function (as in Fig 2). Here, transitions are deterministic and α = 0.4.</p
