  • Fig. 1 Average number of items accurately recalled on tests 1 and 2.

    Test 1 was administered immediately after the onset of stress. Test 2 followed after a 25 min delay. Retrieval practice (RP) refers to the learning technique in which participants study stimuli and take three subsequent recall tests. Study practice (SP) refers to the learning technique in which participants study stimuli four times. Tests occurred on the day after learning. Error bars represent standard errors of the mean. *P < 0.05; **P < 0.01; ***P < 0.001.

  • Table 1 Average number of items recalled on test 1 and test 2 as a function of valence and item type.

    Tests occurred on the day after learning. Standard errors of the mean are given in parentheses.
