Generalization of learning can arise from 2 distinct sources: failure to discriminate a novel test stimulus from the trained stimulus and active extrapolation from the trained stimulus to the test stimulus despite them being discriminable. We investigated these 2 processes in a predictive learning task by testing stimulus discriminability…

Two experiments investigated infants' sensitivity to amount of continuous quantity and to changes in amount of continuous quantity. Found that 6-month-olds looked significantly longer at a novel quantity than at the familiar quantity. Nine-month-olds looked significantly longer at an impossible event than at a possible event. Findings question…

The purpose of the study was to test the discriminative cue hypothesis by attempting to train pupils to increase effort following a high expectancy condition and to reduce effort following a low expectancy condition. Fourth grade high-IQ low achievers were used as subjects in the study, because the authors felt that while they would learn fast,…
