In one work, this thinker described scientific knowledge as “perpetual evolution” to rebut claims that only historians or psychologists should study the development of ideas. This thinker began theorizing about childhood mistakes in problem solving while working under Alfred Binet. This (-5[1])thinker explained the development of knowledge by discussing cognitive equilibration (15[1])between (-5[1])two of his central concepts. (15[2])Four of this thinker’s lectures appear in the book (*) Genetic Epistemology, (10[2])named for one (10[1])of his theories. (10[2]-5[1])This (-5[1])psychologist (-5[2])discussed (10[1])“assimilation” (-5[1])and “accommodation” (10[6]-5[1])as two (10[2])methods (10[2])of adapting (10[2])schemas (10[3])to take in (10[1])new (10[1])information. (10[3]-5[1])A (10[1])model (10[1])established by this psychologist (-5[1])begins with sensorimotor (10[4]-5[1])and (10[1])preoperational (10[5])stages. (10[7]-5[1])For 10 (10[1])points, name this (10[1])Swiss psychologist (10[1])who created a four-stage (10[1])model of cognitive (10[1])development. (10[2]0[1])■END■ (10[5])
