Pictures and Words
Cognitive Daily has an excellent summary of a paper by Foos and Goolkasian:
Recent research by Paul W. Foos and Paula Goolkasian is beginning to shed light on the difference between memory for pictures and words. They had previously found that while short-term memory for simple line drawings was superior to memory for printed words, the advantage disappeared when the word was spoken. This suggests that perhaps the difference between pictures and words in memory isn’t as different as we might think. In a new study, they set out to explore these differences more systematically.
The rest is here. The paper is Foos, P.W., & Goolkasian, P. (2005). Presentation formats in working memory: The role of attention. Memory & Cognition, 33(3), 499-513.
