“…Finally, no significant effect of illuminance was found on BR, which is also supported by earlier studies suggesting that BR can be determined by many factors which makes it open to contamination, and thus is less often used as an ocular parameter in this field of research. 61–63…”

This study explored the impact of daylight illuminance on cognitive load during visual display terminal use by means of various physiological, performance and subjective measures. Repeated-measures design was adopted to identify the impact of variations in daylight levels that were manipulated through the shading system configurations (shading-on; shading-off). A total of 30 subjects performed visual and cognitive demanding tests. Performance measures were supported by subjective data and eye-related measures during the experimental analysis. Results revealed that the use of a shading system had positive impact on sustained attention. Concerning ocular measures, percentage of eye closure values showed opposite tendencies among vigilance and sustained attention demanding tests. Eye aspect ratio-max and blink duration were significantly correlated with reported glare sensation. In all tests, eye aspect ratio-max was found significantly higher in lower illuminances. Search velocity was significantly correlated with ocular variables in higher illuminances whereas sustained attention showed an opposite trend. This, initially, explains that even slight differences in daylight illuminance might have distinctive effects on the relationship between different groups of assessment variables while measuring cognitive load. Secondly, it proves the significance of carrying out sensitive experiments in terms of both light levels and test characteristics. Practical application: The findings of this study could suggest that a practical application, the use of a shading device, might deliver an efficient solution on such a multifaceted question about the potential effects of luminous environment on the evaluation of cognitive load. Work environments might be considered as cognitively efficient if only the harmony of less mental effort, more satisfaction and less health problems exist, which together ultimately deliver higher work performance. In real-world work environments, application of such shading devices involves advantages not only for avoiding excessive daylight exposure or optimizing energy consumption, but also facilitating cognitive, affective and physiological processes of individuals.

“…Acute care clinicians: enrolled nurses, registered nurses and medical doctors employed in Queensland's Public Health Sector were eligible to participate in the study. Eligible participants were required to use the most prevalent EWS used in Queensland, Australia, called Q-ADDS -Queensland Adult Deterioration Detection System [14,15]. It was important to capture data about the use of EWS from both nurses and doctors as these cohorts engage with the EWS in varying ways.…”

Background: Early warning systems (EWS) are most effective when clinicians monitor patients' vital signs and comply with the recommended escalation of care protocols once deterioration is recognised. Objectives: To explore sociocultural factors influencing acute care clinicians' compliance with an early warning system commonly used in Queensland public hospitals in Australia. Methods: This interpretative qualitative study utilised inductive thematic analysis to analyse data collected from semi-structured interviews conducted with 30 acute care clinicians from Queensland, Australia. Results: This study identified that individuals and teams approached compliance with EWS in the context of 1) the use of EWS for patient monitoring; and 2) the use of EWS for the escalation of patient care. Individual and team compliance with monitoring and escalation processes is facilitated by intra and inter-professional factors such as acceptance and support, clear instruction, inter-disciplinary collaboration and good communication. Noncompliance with EWS can be attributed to intra and inter-professional hierarchy and poor communication. Conclusions: The overarching organisational context including the hospital's embedded quality improvement and administrative protocols (training, resources and staffing) impact hospital-wide culture and influence clinicians' and teams' compliance or non-compliance with early warning system's monitoring and escalation processes. Successful adoption of EWS relies on effective and meaningful interactions among multidisciplinary staff.

“…A nudge is "any aspect of the choice architecture that alters people's behavior in a predictable way without forbidding any option or significantly changing their economic incentive" (p. 6). Nudging has been applied in human-computer interaction, as well as in other domains, including marketing, social marketing, and public policy (e.g., [62]), with the overall aim of facilitating the processing of important data [63] and providing individuals with a shortcut to action and behavior change [64].…”

“…Second, by displaying elements in the areas of the screen that are spontaneously viewed first [70], we hoped to meet participants' needs [66]. More specifically, with reference to Cornish et al [63], we hoped to facilitate the processing of important data and reduce cognitive demand through the design of the interface. Consequently, we expected participants to express greater satisfaction after being exposed to elements placed in the middle of the screen rather than on the side, especially when these were central rather than peripheral elements of the social representations.…”

Social representations and interface layout: A new way of enhancing persuasive technology applied to organ donation

et al. 2020

Although campaigns promoting organ donation have proved their effectiveness, increasing the number of people who explicitly agree to become donors is still difficult. Based on the social marketing notion of persuasive technology, we reasoned that it was timely to focus on the design of this persuasive technology and to analyze its contribution in particularly challenging contexts such as organ donation. More specifically, the originality of the present study lay in the way we linked the field of persuasive technology to the theory of social representations, and combined them with an analysis of the ergonomic aspects of interface layout. This study had two complementary goals. The first was to determine whether the sociocognitive salience of the central elements of social representations (i.e., the most frequent and important themes related to the subject—here, organ donation—for individuals), can be used to achieve persuasive outcomes. The second was to determine whether interface layout, in terms of information location and background characteristics (color and contrast), can strengthen the persuasive impact. University students (N > 200) were exposed to a computer screen displaying a message involving either central or peripheral elements of the social representations of organ donation (status), placed either in the middle or on one side of the screen (location), and shown against either a white or a blue background (background). Eye-tracking data were recorded, in addition to self-reported data. In line with the elaboration likelihood model, results showed that participants who were exposed to central (vs. peripheral) elements of the social representations of organ donation followed the central route in processing information. Moreover, they had stronger attitudes, and more of them stated that they were actual organ donors. Importantly, however, at least for some variables, these status-related effects were not independent of the interface layout. More specifically, the persuasive impact of the central elements was enhanced when the information was displayed in the middle (vs. the side) of the screen and when it was displayed on a white (vs. blue) background. We discuss the theoretical and practical issues raised by these results.
