“…Some ERP components are used in ergonomic studies. For example, N400, which typically is activated 350 to 480 ms after a stimulus starts, reflects semantic conflict during traffic sign understanding (Hou & Lu, 2018). The results presented herein confirm that the ERP method could be useful for human factor researchers to investigate how to ensure people remain vigilant to reduce accidents in work environments.…”

Objective The purpose of this study was to investigate the effects of semantic congruence and incongruence on sign identification by using event-related potentials (ERPs). Background Sign systems have crucial roles in public spaces and traffic facilities. Poorly designed signs can easily confuse pedestrians and drivers and reduce the efficiency of public activities and urban administration. Method Thirty-one participants completed a sign identification experiment independently in a laboratory setting. Experimental materials were selected from GB/T 10001, a Chinese national recommendation standard that is officially named Public Information Graphical Symbols for Use on Signs. All ERP data were processed using MATLAB 13b, and behavioral data were analyzed using Stata 14. Results N170, P200, N300, and N400 components were induced during semantic processing. Statistical analysis revealed that semantic congruence has a main effect on N300 in the frontal region and has a main effect on N400 at FZ in the frontal region, CPZ in the parietal-central region, and PZ in the parietal region. Amplitudes of N300 induced by picture–word matching were considerably different between the two experimental conditions at electrodes FZ and FCZ. Amplitudes of N400 were significantly larger in the incongruent condition than in the congruent condition. Conclusion The study demonstrated that N300 and N400 are promising indicators for measuring semantic congruence in future sign design. Application Our findings provide ERP indicators for measuring the semantic congruence of sign design, which can be easily applied to improve the efficiency of sign design and sign comprehension.

“…We selected the FC1, FCz, FC2, F1, Fz, and F2 electrodes to analyze N100 and selected the FC1, FCz, FC2, CP3, CPz, and CP4 electrodes to analyze P200. Many studies have explored the semantic processing of picture–word pairs and discovered that N400 activity is elicited and distributed in the parietal regions of the brain ( Ma et al, 2016 ; Hou and Lu, 2018 ). We selected the CP3, CPz, CP2, P–P3, Pz, and P4 electrodes to analyze N400.…”

“…The peak N400 amplitude occurs approximately 300–500 ms after the onset of stimuli. N400 is sensitive to semantic incongruence and has been observed in many studies on semantic conflict related to non-verbal stimuli that used elements, such as pictures, traffic signs, and mathematic symbols ( Barrett and Rugg, 1990 ; Hou and Lu, 2018 ). Studies have indicated that large N400 amplitudes can be elicited using expressions with semantic incongruence.…”

“…For instance, a larger N400 amplitude was elicited when animal names were used with vehicle pictures than when appropriate vehicle names were used ( Ma et al, 2016 ). Similarly, semantically incongruent traffic sign–word pairs caused high N400 amplitudes ( Hou and Lu, 2018 ). Overall, the N400 amplitude is a suitable indicator for detecting semantic incongruence or conflict regardless of the stimulus modality.…”

Effects of Design Aesthetics on the Perceived Value of a Product

Design aesthetics play a crucial role in product design. Stakeholders expect to develop highly valuable premium products by improving the design aesthetics of products. Nevertheless, the question of how to evaluate the value of design aesthetics has not been fully addressed. In this study, the effects of design aesthetics on the evaluation of the value of a product were investigated through a strictly controlled experiment in which the neural responses of the participants were measured. Forty participants completed the design aesthetics experiment in a laboratory setting. Images of products were divided into two categories: those representing high– and low–design-aesthetic stimuli. Both types of images were labeled with the same price. Overall, the images representing high design aesthetics elicited smaller N100 and lower P200 amplitudes than did the images representing low design aesthetics. This finding indicates that low design aesthetics attracted more attention than high design aesthetics did and that high design aesthetics triggered positive emotions. Low–design-aesthetic products elicited a larger N400 amplitude. This finding reveals the inconsistency between labeled and expected prices. The present study indicates that the N400 component can be used as an indicator for measuring the perceived value of a product in a future product design study. Our study provides event-related potential indicators that can be easily applied in decision making for measuring the perceived value of a product’s design.

The interaction between children and books is an essential part of the reading experience. Publishers all over the world are working to cultivate reading habits in children and attract attention to traditional books. Considering the invaluable nature of these early reading experiences. This paper investigated the effects of book interaction design on 5–6 years old children, taking into account reading preferences, measuring reading time, and emotional response to improve their reading experience and potentially design books according to these interactions. The results showed that preschool children (5–6 years old) prefer sensory interaction, and that book interaction design has a significant influence on reading time, affective experience, and subjective ratings. Girls around 5–6 years preferred folding interaction and pop-up interaction in reading. This study summarizes these results in order to provide practical guidelines for book publishers, enabling them to design better books for children.
