This paper gives a state-of-the-art report on the use of techniques based on personal construct psychology to automate knowledge engineering for expert systems. It presents the concept of knowledge support systems as interactive knowledge engineering tools, states the design criteria for such systems, and outlines the structure and key components of the KITTEN implementation. KITFEN includes to...

The effects of accommodation demand and deprivation on the development of ocular optics was investigated in four groups of kittens (total n = 29). Group 1 consisted of five normal kittens; group 2 (nine kittens) had monocular radial keratotomy to induce relative hypermetropia and more accommodation demand as well as to impart interocular refractive differences (anisometropia); group 3 (eight ki...
