The significance of massed and distributed practice in discrimination learning to criterion by goldfish was studied. All animals were trained to discriminate between 6 horizontal black and white stripes (positive stimulus) and 2 vertical black and white stripes (negative stimulus). 5 groups of animals, 12 Ss each, got different training programs. Groups varied in number of trials per day (30, 10, 5 successive trials) and in distribution of trials over the day (30 trials given in blocks of 5 with ITI of 1 h or 5 trials, each spaced by an ITI of 1 h). In general animals with a small number of massed trials/day were superior in early acquisition period. When trials/day were spaced the method proved to be more efficient. The training method showed no effect concerning retention.
研究了集中练习和分散练习在金鱼辨别学习达到标准过程中的重要性。所有动物都接受训练，以区分6条水平黑白条纹（正刺激）和2条垂直黑白条纹（负刺激）。5组动物，每组12只，接受不同的训练程序。各组在每天的试验次数（30次、10次、5次连续试验）和一天中试验的分布方式（30次试验以每5次为一组，组间间隔1小时，或5次试验，每次间隔1小时）上有所不同。一般来说，每天进行少量集中试验的动物在早期习得阶段表现更优。当每天的试验进行间隔安排时，该方法被证明更有效。训练方法对记忆没有影响。
