Training the horizontality concept in a group of nontransitional children.
The present investigation attempted to train Piaget's horizontally concept in a group of young, nonoperational first-grade boys and girls. Two groups of 20 Ss each (training vs. control) comprised the sample (X = 6 yrs., 9 mos.). Only Ss who failed the waterline pretest were included. Experimental Ss were given individual training to anticipate the waterline by drawing a line on outline pictures. They were given explicit knowledge of results as well as experience copying the actual waterline. Results indicated a significant improvement for the training group, which was sustained in a follow-up test, one week later. Also, there was transfer of training to a round-sided jar not used in training. The results are discussed in terms of Piaget's theoretical notions of assimilation and accommodation as related to explicit feedback and visual-motor practice.
