Experiments on the Appraisal of Visual Environment under the Lighting Conditions in a Scale Model

This paper has been developed in the IEA SHC Task 61 Integrated Solutions for Daylighting and Electric Lighting scope. Task 61 aims at developing and testing strategies and solutions combining daylighting, electric lighting, and the most suitable control systems. Some of the planned activities, especially in the Subtask A: User perspective and requirements, were not possible due to the Coronavirus pandemic restrictions. On the other side, new challenges emerged, for example, the migration of workplaces to homes. It occurred both for professionals and students, and the lighting conditions in these new improvised workplaces are unknown. In this context, the article presents the part of the home office survey aiming to understand lighting conditions for students in home offices in different countries: Brazil, Italy, Japan, Columbia, Denmark, and Poland. The paper also seeks to define the current limitations of a home office in providing a resilient visual environment.

Preliminary Study

A measure to mitigate the spread of the COVID-19 virus during the first year of the pandemic was to stay home. Thus, working and learning activities have migrated to dwellings under the so-called home office scheme. In this context, exploring the lighting conditions in home offices from the occupant's perspective is vital for understanding the quality of the perceived visual environment at home. Based on data collected in Brazil and Colombia, this preliminary study aimed to investigate occupant’s perception of the luminous environment in home offices and the influence of regional and personal characteristics. This study is part of broader research related to Subtask A of IEA Task 61, "Integrated Solutions for Daylighting and Electric Lighting." Occupant's subjective assessments were collected from December 2020 to March 2021 through an online survey with professionals working from home. The results show that most professionals have an entire room for the home office, and these are more satisfied with the visual environment. In general, higher satisfaction was achieved when the lighting level was perceived as brighter and strong reflections were associated with disturbing glare situations. Most of the occupants perceived the light and colours as neutral. Daylight is more appreciated than artificial light. Participants located between 20°S and 34°S latitude were less satisfied with the visual environment in the home office. The first approach is part of comprehensive research, generating new data about lighting in home offices to subside guidelines for improving housing projects.

Second Wave

In order to model within-person (WP) variance in a reaction time task, we applied a mixed location scale model using 335 participants from the second wave of the Zurich Longitudinal Study on Cognitive Aging. The age of the respondents and the performance in another reaction time task were used to explain individual differences in the WP variance. To account for larger variances due to slower reaction times, we also used the average of the predicted individual reaction time (RT) as a predictor for the WP variability. Here, the WP variability was a function of the mean. At the same time, older participants were more variable and those with better performance in another RT task were more consistent in their responses.

Two Samples

This study evaluated the psychometric properties of a self-report scale for assessing perceived driver competence, labeled the Self-Efficacy Scale for Driver Competence (SSDC), using item response theory analyses. Two samples of Swedish driving-license examinees (n = 795; n = 714) completed two versions of the SSDC that were parallel in content. Prior work, using classical test theory analyses, has provided support for the validity and reliability of scores from the SSDC. This study investigated the measurement precision, item hierarchy, and differential functioning for males and females of the items in the SSDC as well as how the rating scale functions. The results confirmed the previous findings; that the SSDC demonstrates sound psychometric properties. In addition, the findings showed that measurement precision could be increased by adding items that tap higher self-efficacy levels. Moreover, the rating scale can be improved by reducing the number of categories or by providing each category with a label.

Rating Scale Model

This paper presents an IRT analysis of the Beck Depression Inventory which was carried out to assess the assumption of an underlying latent trait common to non-clinical and patient samples. A one parameter rating scale model was fitted to data drawn from a patient and non-patient sample. Findings suggest that while the BDI fits the model reasonably well for the two samples separately there is sufficient differential item functioning to raise serious duobts of the viability of using it analogously with patient and non-patient groups.

The One

The visual environment consists of global structures (e.g., a forest) made up of local parts (e.g., trees). When compound stimuli are presented (e.g., large global letters composed of arrangements of small local letters), the global unattended information slows responses to local targets. Using a negative priming paradigm, we investigated whether inhibition is required to process hierarchical stimuli when information at the local level is in conflict with the one at the global level. The results show that when local and global information is in conflict, global information must be inhibited to process local information, but that the reverse is not true. This finding has potential direct implications for brain models of visual recognition, by suggesting that when local information is conflicting with global information, inhibitory control reduces feedback activity from global information (e.g., inhibits the forest) which allows the visual system to process local information (e.g., to focus attention on a particular tree).

Momentary Assessment

Abstract. The mixed-effects location scale model is an extension of a multilevel model for longitudinal data. It allows covariates to affect both the within-subject variance and the between-subject variance (i.e., the intercept variance) beyond their influence on the means. Typically, the model is applied to two-level data (e.g., the repeated measurements of persons), although researchers are often faced with three-level data (e.g., the repeated measurements of persons within specific situations). Here, we describe an extension of the two-level mixed-effects location scale model to such three-level data. Furthermore, we show how the suggested model can be estimated with Bayesian software, and we present the results of a small simulation study that was conducted to investigate the statistical properties of the suggested approach. Finally, we illustrate the approach by presenting an example from a psychological study that employed ecological momentary assessment.
