Hi,
I need help on a lexical decision task.
For the non-word I got, each word has three non-words accordingly (add a letter, subtract a letter, and switch order). For example, apple can be applle, aple, alppe. So now I have four word sets (original words, add a letter words, subtract a letter words, and switch order words).
I need the software to random select from the four word sets without repetition of the same word (For example, applle and aple can not be shown in the same experiment since they are from the same word.) I don't know how to do it. Can anyone help me please?
Thank you!
