Celebrity Caricature

In a lecture titled The History and Art of Caricature (September 2007, Queen Mary 2 Lecture theatre), the British caricaturist Ted Harrison said that the caricaturist can choose to either mock or wound the subject with an effective caricature. Drawing caricatures can simply be a form of entertainment and amusement - in which case gentle mockery is in order, or the art can be employed to make a serious social or political point. A caricaturist draws on (1) the natural characteristics of the subject (the big ears, long nose or whatever); (2) the acquired characteristics (stoop, scars, facial lines etc.); and (3) the vanities (choice of hair style, spectacles, clothes, expressions and mannerisms).
Ramachandran and Hirstein suggested that caricature is related to peak shift. In the peak shift effect, animals sometimes respond more strongly to exaggerated versions of the training stimuli. For example, if a rat is trained to respond to a rectangle of a particular aspect ratio, and to avoid a square, when later presented with several rectangles it will prefer the one with the most elongated aspect ratio (this being the one that is most different from the square) rather than the original rectangle used in training. Ramachandran and Hirstein speculated that cells in a monkey brain that respond to particular faces would respond more strongly to caricatured versions of the face. This effect has been confirmed in FMRI experiments by Tsao.
