The Effects of Task Screening and Scoring Objectively on Retardate Conservation Performance.
Langley, Jan; And Others
Studied were 48 retarded children, 9- to 18-years-old, (mental age 4 to 8 years) to determine effects of task screening and objectivity of protocol scoring on achievement of the concept of conservation. Results indicated no significant differences in achievement of conservation as a function of either experimental variable. Also data indicated that the percent of Ss showing conservation was significantly lower than predictions made in Greenfield's work (1966). The investigation does not provide support for the hypothesis that mentally retarded children develop the ability to conserve mass to the same degree as normal children. (MC)
