Next, we will show you some words one at a time. Some of them be from the list you just studied and some of them will be new.

For each word, please indicate whether you think the word was on the list you studied. You will respond using a slider that moves from -100 to +100. +100 means that you are absolutely certain that the word WAS on the studied list. -100 means that you are absolutely certain that the word was NOT on the studied list. After you move the slider to the position you want, press the "NEXT" button to see the next word. Please move the slider away from 0 on each trial. You will not be able to go back and change your answers.

First, thank you very much for taking part in our study.

Producing information (e.g., by speaking aloud or typing) has been shown to result in improved memory for that information. Production has also been shown to reduce the prevalence of false memories for information that was not actually encountered.

In this experiment, some of the words you saw during the memory test had not been presented to you to study but were related to some of the studied words (e.g., you might have seen NIGHT, DREAM, and PILLOW and then tested on the word SLEEP). This procedure typically results in high rates of false memory for the related word.

Factors that increase the production benefit for true memory might decrease the production protection against false memory. For example, the production benefit for true memory is much larger if you produce some of the words but not others compared to producing all of them. The opposite is true for false memory, where the protection is larger if you produce all of the words.

We are testing whether this opposing pattern generalizes to other factors. You either saw the studied words on a computer screen or heard them through your speakers or headphones. Based on earlier research, we expect the production benefit for true memory to be larger if you heard the words, because typing would then draw your attention to unique visual aspects of the word as well. If the opposing pattern we are interested in does generalize, we would expect that difference to be accompanied by a smaller reduction in false memory in the same experiment.

The findings will contribute critical information to our current understanding of human memory on a detailed theoretical level.
