An eye tracking study: positive emotional interface design facilitates learning outcomes in multimedia learning?

Emotional design pictures: Pleasant but too weak to evoke arousal and attract attention?

A new field of research builds on the theoretical assumption that distinct design manipulations, such as human-like features with appealing colors (emotional design), foster multimedia learning by influencing the learners' affective state (i.e., valence and arousal) and attention. Empirical studies, however, provide inconsistent findings of the affective potential of emotional design, underlining the need for psychophysiological measurements to assess the affective state and attention more objectively. The effects of differently designed stimuli (picture-text combinations with anthropomorphic pictures in bright and saturated colors [emotional design], picture-text combinations with non-anthropomorphic pictures in grayscale [neutral design], and plain text [control design]) on junior high school students' valence (N = 15), arousal (N = 18), and attention (N = 27) were examined. Valence was determined by students' judgments on a rating scale; arousal and attention were assessed by psychophysiological parameters (electrodermal activity of students and their dwell time on stimuli, respectively). To allow the examination of valence and arousal as separate dimensions, two independent experiments were conducted. Results of experiment I show that students perceived emotional design stimuli as more pleasant than stimuli in neutral or control design. Besides, an interaction with the content of the stimuli was found. While the positive effect of the emotional design was found for concepts that could be interpreted as potentially positive (e.g., sunlight) or neutral (e.g., consumer), stimuli representing potentially negative concepts (e.g., dead consumer) were not perceived as more pleasant if presented in emotional design. Experiment II shows that emotional design did not induce higher arousal than neutral and control designs and did not attract more attention. Instead, the text within picture-text combinations (emotional and neutral designs) attracted more attention when pictures were presented in neutral than in emotional design. By investigating the emotional state more differentiated and by examining arousal and attention using psychophysiological parameters, the present study helps to understand the heterogeneous findings of previous studies.

Colors and Learner’s Gender Evoke Different Emotional and Cognitive Effects in Multimedia Learning

The emotional design principle avers that highly saturated warm colors in multimedia learning presentations can elevate affective-motivational, cognitive, and learning outcomes. While warm and achromatic grayscale color tones have been explored extensively, relatively less research examines the effects of cold colors in multimedia learning. This study explores how color tones (warm, cold, and achromatic grayscale) and learners’ gender influence positive emotions, intrinsic motivation, cognitive load, and transfer performance. An online experiment was conducted where learners pursuing IT courses in an Asian university ( $n=204$ ) engaged with either one of the multimedia learning lessons on distributed denial-of-service attack imbued with (1) a warm color tone, (2) a cold color tone, and (3) an achromatic grayscale color tone. Findings show that the cold color tone was associated with fewer enhanced positive emotion types than the other color tones. Compared to the achromatic grayscale color tone ( $M=2.38$ , $\text{SD}=1.88$ ), significantly higher extraneous cognitive load ratings were observed with the warm color tone ( $M=3.26$ , $\text{SD}=1.96$ ) and the cold color tone ( $M=3.24$ , $\text{SD}=2.18$ ). Following reports by some learners, this could be attributed to the overly vivid and saturated chromatic colors impairing the learners’ visual and cognitive processes, causing them to rate the multimedia learning experience with warm and cold color tones as more difficult than with the achromatic grayscale color tone. Male learners in the warm color tone condition ( $M=4.93$ , $\text{SD}=3.46$ ) performed marginally better on the transfer posttest than male learners in the cold color tone condition ( $M=3.49$ , $\text{SD}=3.45$ ) and male learners in the achromatic grayscale color tone condition ( $M=3.44$ , $\text{SD}=2.69$ ). In contrast, female learners in the warm color tone condition ( $M=1.75$ , $\text{SD}=1.62$ ) performed marginally worse than female learners in the cold color tone condition ( $M=3.83$ , $\text{SD}=3.92$ ) and significantly worse than female learners in the achromatic grayscale color tone condition ( $M=3.67$ , $\text{SD}=2.50$ ). Overall, these results show that gender can shape the effects of warm colors on learning—the warm color tone can enhance male learners’ but stifle female learners’ transfer performance. Moreover, this study aligns with recent studies that colors as an emotional design feature may lead to higher cognitive load ratings. This paper discusses the theoretical and practical implications and submits a future outlook for broadening the research domain.
