In the present experiment a mood-state-dependent retrieval hypothesis and a mood-congruity hypothesis are tested. The first hypothesis states that recall is higher when mood at test matches mood at input than when it does not match. The second hypothesis states that people learn more about events that match their mood state. Both hypotheses are consistent with the network model of mood and memory proposed by Bower and his colleagues. Our study was conducted to test the cited hypotheses with normal subjects (instead of highly hypnotizable subjects as in the studies by Bower et al.) and with a comparatively mild mood-induction technique. Another aim was to test different predictions from the two hypotheses. We experimentally varied mood (happy vs. sad), both at learning and at recall by using the Velten technique. Additionally, the emotional content (pleasant vs. neutral vs. unpleasant) of the text to be learned was manipulated. The empirical evidence with some restrictions favored the mood-state-dependent hypothesis and disagreed with the mood-congruity hypothesis. Possible explanations for the failure to obtain a mood-congruity effect are offered, and the results are discussed with reference to a network model of mood and memory.
