Tended to remember more about the person in the same mood that was induced. People remember more if they are in the same mood when they recall as they were when they learned the material. Mood induced by hypnosis. Learned one list when happy and the other list when sad. Had better recall of happy list when happy and better recall of sad list when sad.
People put in good, bad or neutral mood by reading self-referential statements.
Given 5 trials on a list-learning experiment. Best performance by those in a neutral mood. Worst performance by those in a bad mood. Therefore can be a retrieval cue, more activation spreads to nodes in a similar mood etc. Predisposes the person to encode experiences congruent with this mood, directs their retrieval of sad content.
