“…A prior study using the arrow flanker task found that even in the high working memory load condition, the participants could still keep the similar RT and accuracy rate for the incongruent trials compared to that in the low load condition ( Wei and Zhou, 2020 ). Besides, the most effective safety signs are designed less complexly that require less attention resources in order to promote the comprehension rate ( Siswandari and Xiong, 2015 ; Tejero et al, 2018 ; Babić et al, 2020 ). Even in an implicit evaluation of the safety signs, people can also effectively distinguish the different levels of the hazard ( Bian et al, 2020 ).…”

The safety sign is important in our daily life and workplace to prevent potential safety issues. However, it remains undetermined whether the safety signs would influence the cognitive control ability of the people, which serves to guide the behaviors in a goal-directed manner. Therefore, this study aimed to examine the effect of safety signs on cognitive control by uncovering the behavioral performance and neural manifestations underlying the monitoring of conflict and error. The participants performed a flanker task after watching low- and high-hazard safety signs with the electroencephalogram (EEG) data recorded continually. The behavioral results indicated a classic congruency effect with higher accuracy rate and faster response time under a congruent condition compared to an incongruent condition. However, no hazard effect on behavioral performances was observed. The results of event-related potentials (ERPs) demonstrated a more negative N2 elicited by the incongruent trials and an increased (error-related negativity) ERN difference between the error and correct responses in the high-hazard condition compared to those in the low-hazard condition, implying that the monitoring of the conflict and error were both enhanced after watching the high-hazard safety signs. This study contributes to the understanding of the relationship between safety signs and cognitive control, and further expand the measurements that can be applied to assess the effectiveness of safety signs design.

Legibility of Pharmaceutical Pictograms

The design of medicinal information in leaflets and labels is often criticized for not meeting patients' needs. For that reason, there is an increasing focus on how the use of pictures, such as pictograms, may benefit patients on their medical journey. However, before a pictogram can be comprehended it must be legible, which may be a challenge when pharmaceutical information has to be conveyed. Within a limited space many visual details need to be included in order to clarify the intended meaning. While we have abundant information about the comprehension of pictograms, we know very little about the legibility - the ability to visually identify objects - of pictograms. By looking at legibility research into pharmaceutical pictograms from a design perspective, this paper demonstrates that legibility is not prioritized either in theory or in practice. In order to proceed with the use and implementation of pictograms in, for example, patient information leaflets and labels, we need to know more about the features that constitute legibility. To create a research foundation, this paper draws on knowledge of visibility and legibility from related domains. This forms the basis of a discussion of the need for future research to focus on legibility issues, amongst others by incorporating design knowledge into experiments.

“…The physiological processes and cognitive neural mechanisms underlying each phase of a person’s perception, comprehension, and emotional and behavioral responses to warning signs cannot be revealed. In the meantime, the results of self-report methods are influenced by memory and consciousness, which may be biased, particularly for “partially correct” answers [ 7 ]. In order to address the aforementioned issues, some researchers are beginning to employ objective ways to examine the readability of signs.…”

“…In order to address the aforementioned issues, some researchers are beginning to employ objective ways to examine the readability of signs. For instance, participants were required to observe signs of varying comprehensibility while the differences in EEG signals on the cerebral cortex were recorded [ 7 ]. Some researchers also utilized an ERP technique to investigate the symbolism of traffic signs [ 8 ].…”

Dangerous goods marks are the most effective means of alerting individuals to the potential dangers associated with the transport of dangerous goods. In order to gain a better understanding of how dangerous goods marks convey risk information, the cognitive processing of dangerous goods marks was examined by measuring event-related potentials (ERPs). We recruited 23 participants, and their ERP data were recorded. We discovered that the dangerous goods marks elicited a larger P200 amplitude and a smaller N300 amplitude, indicating that, compared to other marks, the dangerous goods marks exhibited stronger warning information and drew more attention from the subjects. Simultaneously, dangerous goods marks elicited insufficient emotional arousal in individuals. Therefore, these findings suggest that the designs of dangerous goods marks need to be improved, such as improving the graphic consistency. Changes in ERP patterns can be used to measure the risk perception level of dangerous goods marks, which can be used as an accurate indicator of the effectiveness of warning sign design. In addition, this study provides a theoretical foundation for the cognitive understanding mechanism of dangerous goods marks.
