Second-graders were tested for negative transfer and retroactive interference using an A-B, A-D paradigm. Four-pair, word-number lists were aurally presented to the children. Subjects were classified as being whole-only encoders or multiple encoders by the use of a recall test presented after list one. Significant negative transfer and retroactive interference were found. The multiple encoders experiences less difficulty in learning the second list that did the whole-only encoders, but these two groups did no differ with regard to transfer or retroactive interference effects. The results were considered in the context of Martin's encoding variability hypothesis.

To determine the relationship among learned helplessness, locus of control, and academic achievement, data from 86 sixth graders were gathered and intercorrelated. Contingency of teacher-administered rewards and punishments as perceived by school children, and helpless behavior of students as judged by their teachers were measured. The Children's Nowicki-Strickland Locus of Control Scale was used to measure locus of control orientation. A positive relationship between academic achievement and locus of control was found. The contingency of reward scale was found to be predictive of academic achievement and helpless behavior. Virtually no significant relationships were found between any of the other variables and the contingency of punishment scale. Helpless behavior was found to be predictive of low academic success and an external locus of control.
