It would then suggest that when learning new vocabulary it is helpful intially to include graphics with a text explaining new items/items of interest. They also mention just using bilingual dictionaries (ie google translator) is not as helpful as having proper annotation that highlights the vocabulary item and explains it.
I have been experimenting myself on the use of including graphics in my mnemosyne flash cards and it was my impression it improved my retention. And also I found that I remember the words better where I was able to put down the explanation given by the teacher or given by the text as annotation. I am finding that if I read a text, I try to look up new vocabulary in a dictionary but cross-checking it with other texts, just to make sure I got the meaning right.
This also seem to be confirmed by the study here
Perhaps there is newer stuff on the subject by now. I still consider their findings interesting.
