Five procommunist and five anticommunist students were presented with anti-Soviet and pro-Soviet paragraphs and tested for recall. The learning and forgetting curves over a nine-week period show that each group excelled in learning and retaining the ideas of the paragraph fitting the attitudes of the group, and the memory divergence between groups increased with time. The more violent paragraph produced greater group differences in memory. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
