11, 2012 /PRNewswire/ --Author Michel Cabanac, the scientist who discovered the phenomena of Alliesthesia, Ponderostat, and Anapyrexia and coined these names for these phenomena, presents his 50-year intensive work on the critical themes of physiology, psychology, and philosophy of pleasure, in his intriguing book The Fifth influence or, The Dialectics of Pleasure.
The authors note that these patterns incorporate aspects of three existing theories in reward/aversion- prospect theory, which includes the fact that people are more strongly motivated to avoid negative outcomes than to attain positive outcomes; the matching law, which describes how the rates of response to multiple stimuli are proportional to the amount of reward attributed to each stimulus; and alliesthesia, which notes that the value placed on something depends on whether it is perceived to be scarce - for example, hungry people place greater value on food than do those who have just eaten.
