Article Citation - WoS: 3Citation - Scopus: 4Attention Mediates the Effect of Emotional Arousal on Learning Outcomes in Multimedia Learning: an Eye-Tracking Study(Routledge Journals, Taylor & Francis Ltd, 2023) Ozcelik, Erol; Aksaray, Sevgi Genc; Genc Aksaray, SevgiRecent findings from psychological studies have shown that emotional arousal improves human memory. However, more evidence is necessary if these results are generalisable to multimedia learning environments. Considering these needs, the study has the goal to examine the effect of emotional arousal on multimedia learning. Fifty-seven participants were presented with instructional materials with either high- or low-arousing words and pictures in an experimental study. The eye movements of participants were recorded while they studied the instructional materials to examine the online processes during learning. The results suggest that emotional arousal enhanced recall and transfer scores. The eye-tracking results demonstrate that emotional arousal attracted attention. The results of the mediation analysis suggest that fixation time on emotional pictures as an indicator of attention mediated the relationship between emotional arousal and learning outcomes. The findings show the importance of the guidance of attention by emotional multimedia elements for learning.Article Citation - WoS: 3Citation - Scopus: 5Enhancing Multimedia Learning by Emotional Arousal(Routledge Journals, Taylor & Francis Ltd, 2024) Arslan-Ari, Ismahan; Ozcelik, ErolSeveral studies in multimedia learning have examined the effect of emotional design. Recent findings from cognitive psychology provide opportunities for educators to use more direct ways of manipulating emotion to enhance learning. These studies have shown that emotionally arousing words and pictures are remembered better than neutral ones. Building upon these findings, this experimental study investigates the effect of arousal of instructional materials on learning. A total of 154 participants were randomly divided into a "high-emotional arousal" and a "low-emotional arousal" group in a between-subjects design. These results suggest that emotional arousal enhanced learning. Mediation analyses show that the effect of arousal on learning was partially mediated by interest. Accordingly, emotional arousal increased interest, which in turn improved transfer scores. The findings imply that motivational factors such as situational interest encouraged elaborative processing and deeper levels of learning. The direct effect of emotional arousal on learning was also significant.Article Remembered or Forgotten Stimuli: a Functional Magnetic Resonance Imaging Study on the Effects of Emotion(Kare Publ, 2020) Kilic, Betul; Ozcelik, ErolObjective: The first aim of this study is to examine why emotional events enhance memory for preceding stimuli. The second goal is to identify brain regions associated with remembering and forgetting by finding brain activation differences during encoding of remembered and forgotten stimuli. The third goal is to examine which brain areas are activated when studying emotional pictures compared to neutral ones. Method: In each trial, a picture of an object followed by an emotional or neutral picture from the Turkish culture were presented to 15 volunteers. The effect of the succeeding pictures on the remembering of preceding stimuli was examined. The participants studied the stimuli in the magnetic resonance scanner and, meanwhile, brain images were taken. The memory performances of the participants were measured with the recognition test administered one week later. Results: Behavioral results suggest that emotion has no effect on memory for preceding stimuli. Functional magnetic resonance imaging results indicate that remembered stimuli compared to forgotten ones caused more activation in left inferior frontal gyrus and left superior medial gyrus. Emotional pictures create more activation in the - mid-temporal gyrus and supramarginal gyrus compared to neutral images. Conclusion: Brain structures in which activations are observed in remembered stimuli compared to forgotten ones (left inferior frontal gyrus and left superior medial gyrus) are responsible for the semantic elaboration and associative memory formation. Thus, it can be concluded that object pictures are remembered because they are processed more deeply. Besides, activations are observed in the areas known to be related to the processing of emotional face expressions when emotional and neutral pictures are compared.
