Show me the meaning! The contextual relevance of images influences the recall and understanding of multimedia RSVP paragraphs

ABSTRACT

This study examined whether images facilitate contextual grouping as effectively as words. College students (N?=?102) read RSVP paragraphs with topics located at the beginning, middle, or end of the paragraph. Paragraph topic was presented as a topic-related image, topic-unrelated image, or written explicitly in text. Topic identification was equally accurate for topic-related images and topic sentences, and less accurate for unrelated images. Paragraphs from the text condition were recalled more accurately than the related and unrelated image conditions. Further, recognition of unrelated images was a positive predictor of the number of logical errors committed during recall. Therefore, related images did not improve memory and comprehension as much as text, and paragraphs with unrelated images negatively affected understanding of the meaning of the paragraph, but not recall. These findings have implications for multimedia information sources such as textbooks or articles that use images to clarify the meaning of the material.
