| Abstract: | BackgroundText illustrated by pictures (i.e., multimedia material) is often used to improve learning outcomes. To support learning, it is essential to understand and specify the ongoing cognitive processes when processing illustrated texts.AimsWe focus on three cognitive processes identified when processing non-illustrated texts: activation, integration, and validation. In three experiments, we investigated whether the three processes occur during the processing of illustrated texts and whether the processes differ between illustrated and non-illustrated texts.SamplesExperiment 1 had 170 participants, Experiment 2 had 221 participants, and Experiment 3 had 132 participants.MethodAll experiments used an adapted version of the contradiction paradigm. In Experiments 1 and 2, participants read texts that contained information that was consistent vs. inconsistent with a later sentence (target sentence). It was additionally varied whether a picture illustrated the consistent vs. inconsistent information. In Experiment 3, only the pictures were consistent or inconsistent with the target sentence. We measured reading times for the target sentence and the following sentence (spillover sentence).ResultsIn all three experiments, reading times were significantly longer in the inconsistent than in the consistent conditions. This prolongation of reading times was not affected by the picture in Experiments 1 and 2.ConclusionOur results indicate that activation, integration, and validation processes are similar when processing non-illustrated and illustrated texts (Experiments 1 and 2) and also occur when information is presented across text and picture (Experiment 3). We discuss the implications for the theoretical foundations of multimedia learning. |
