Many (digital) learning materials are often based on a combination of text and pictures, whereby pictures often only serve a decorative (learning-irrelevant) function. Such decorative pictures were proven as detrimental for learning success. In contrast, research on retrieval cues (also known as memory cues) showed that a visual-semantic connection between the learning information and additional pictures might help to foster later retrieval processes. This experimental series tested if decorative pictures might serve as a retrieval enhancer. For this, four experiments (n₁ = 104, n₂ = 124, n₃ = 161, n₄ = 176) were conducted where a learning video about concepts in marketing was used with and without decorative pictures. In a subsequent learning test (retention and transfer questions) with or without these corresponding decorative pictures, the memory cue effect was examined. Besides, mental load and mental effort, as well as intrinsic motivation were measured. Across all experiments, results showed that the groups with decorative pictures which were only shown in the video performed significantly worse than the other groups (seductive detail effect). Moreover, students with decorative pictures in both the learning and the retrieval phase were found to learn more than groups without decorative pictures (memory cue effect). Significant moderators of this effect were found in the salience of the cues, the associative connection between the cues and the learning information, and the modality of the cues (visual vs. verbal). Results were explained by differences in cognitive and motivational variables. (PsycInfo Database Record (c) 2020 APA, all rights reserved)
