Thirty-six-word equivalents of line drawings were selected from the Snodgrass and Vanderwort (1980) collection of concrete common nouns. Based on Warriner, Kuperman, and Brysbaert’s (2013) norming study, the items had a moderate to mildly positive valence (M = 4.56, SD = 0.743 on a 1 – 9 scale). For control purposes, two different orders of the words were created and participants in both groups were randomly assigned to one of those orders. Upon arrival, participants were informed that the study was concerned with the influence of learning on memory. Participants in the free recall condition were asked to study a series of words that will appear on the monitor for a memory test that will follow the word presentation. Each word was presented for 5 seconds followed by blank screen for 2 seconds. Following the last word, a dark screen signaled the end of study phase. To reduce recency effects, a word search task of Canadian place names was presented; participants had 2 minutes to complete this task. At test, participants received a sheet of paper containing 36 lines and were told that they would have 5 minutes to write down as many of the previously words as they could remember. At the end of 5 minutes, a second sheet of paper containing 36 lines was given and participants informed that there would now be a second test in which they were to try to improve on the number of words recalled on the first test and given 5 minutes to complete that test. After completing the second test, a third test was announced with identical instructions and time limit. At the end of the third test, participants were debriefed and thanked. An identical procedure was followed for the classification accuracy participants except that after seeing the words, they were told that they would also see the set membership of that word (either set A or set B) and were asked to memorize both the word and the set. Each word was presented for 5 seconds followed by a set identifier for 2 seconds. On test 1, participants received a sheet of paper with two columns labeled set A and set B, and 36 lines underneath each column. They were asked to recall as many of the words as they could, classifying each word into the correct set in which it appeared, within the 5-minute time limit. Similar instructions were given for tests two and three which followed immediately after completing the previous test. Participants were then debriefed and thanked.
