“…They suggested that N400 reflects a crucial unconscious categorization in the selection of branded products. N400 has been reported to be mainly distributed in the frontal regions in studies using word–word combinations ( Hamm et al, 2002 ; Schneider et al, 2014 ) and in the parietal and occipital regions in studies using picture–word combinations ( Ma et al, 2016 ; Lu and Hou, 2020 ). In the current study, N400 was distributed in the occipital regions, which is consistent with the results of previous studies ( Ma et al, 2016 ).…”

“…Studies have indicated that presenting people with verbal stimuli that they perceive as exhibiting semantic conflict can elicit N400 ( Barrett and Rugg, 1990 ). N400 has been found to be effective for detecting semantic conflict in non-verbal stimuli ( Ma et al, 2016 ; Lu and Hou, 2020 ). The current study found that N300 and N400 can be used to detect the expected consistency between products and their prices.…”

“…The results indicated that a significantly larger N400 amplitude was elicited for pictures of low-design-aesthetic products than for pictures of high-designaesthetic products, which indicates that a high N400 amplitude was elicited when the labeled price was inconsistent with expectations. Inconsistent picture-price combinations elicited larger N400 amplitudes than did a consistent picture-price combinations (Ma et al, 2016;Lu and Hou, 2020). Wang et al (2012b) used N400 as an indicator to detect brand inconsistency with product attributes.…”

“…Most importantly, we hypothesize that design aesthetics add value to a product. The pairing of a low–design-aesthetic product with a high price may lead to cognitive incongruences ( Lu and Hou, 2020 ). This hypothesis was tested in the current study by the large N400 values elicited by products with low design aesthetics that were labeled with a relatively high price.…”

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.

“…Prior research has shown that ERPs are conducive to understanding how people process safety signs (Fu et al, 2017;Ma et al, 2018;Lu and Hou, 2019;Bian et al, 2020;Zhu et al, 2020). For instance, warning signs with higher hazard levels are associated with increased N1, N2, and P300/LPP components (Ma et al, 2010(Ma et al, , 2018Fu et al, 2017;Bian et al, 2020), and a reduced P2 component (Ma et al, 2018;Bian et al, 2020).…”

Warning signs, as a type of safety signs, are widely applied in our daily lives to informing people about potential hazards and prompting safe behavior. Although previous studies have paid attention to the color of warning signs, they are mostly based on surveys and behavioral experiments. The neural substrates underlying the perception of warning signs with different background colors remain not clearly characterized. Therefore, this research is intended to address this gap with event-related potentials (ERPs) technique. Warning signs with three different background colors (i.e., white, yellow, and blue) were used in the experiment. The results showed that the perceptual differences between different warning signs were present in the form of differential ERPs components (P1, N1, P2, N2, and P3) though subjects were not required to explicitly attend to the warning signs.

Accurate comprehension of safety signs plays a critical part in warning construction workers of potential work hazards. However, existing studies have rarely investigated construction workers' comprehension of safety signs at construction sites. Moreover, existing evaluation methods are generally based on subjective behavior tests, questionnaires, and interviews. Therefore, this study examined the effects of semantic congruity on the comprehension of safety signs, including two sign types (prohibition vs. warning signs) and two conditions (semantic congruence vs. incongruence), combining event‐related potentials and time‐frequency analysis measurements. Adopting the S1‐S2 paradigm, electroencephalogram data were recorded when participants decided whether S1 and S2 were semantically congruent or not. Results showed that the semantically incongruent safety sign‐word pairs elicited larger N400 amplitudes and increased theta (3–8 Hz) power in 300–420 ms. The amplitude of N400 in the semantically incongruent condition of the warning sign‐word pairs was more negative than that for the prohibition sign‐word pairs, while there were no significant differences between the prohibition and warning sign‐word pairs in the semantically congruent condition. A greater late positive potential (LPP) (550–750 ms) was also elicited in the semantically incongruent safety sign‐word pairs, which was different from previous studies that observed larger LPP in congruent conditions. These results suggest complicated cognitive mechanisms of safety sign comprehension in construction workers. This study extends safety sign comprehension research by using electrophysiological approaches and provides useful indicators for researchers or safety engineers to measure the semantic congruity of proposed sign designs.
