Hold Tight: Carroll Izard's Contributions to Translational Research on Emotion Competence

Lighting environmental assessment in enclosed spaces based on emotional model

Lighting assessment in special operating environments like enclosed spaces is of great research significance and value. In addition to investigating the visual ergonomics of workers, the emotional monitoring and guidance of workers in enclosed spaces is also a research focus. Based on the Circumplex emotion model theory, this paper designs an experiment to assess emotions in an enclosed space with 6 different lighting settings (2 correlated color temperature (CCT) × 3 illuminance levels). From the perspective of subjective assessment, participants used a rapid sensory analysis method (Check-all-that-apply, CATA) and a Subjective Coordinate Scale (SCS) method for rapid ambience perception checking and emotional self-reporting of lighting settings. From the perspective of objective evaluation, the participants' facial expressions were recorded during the experiment using a camera, and then the recorded facial expressions were automatically analyzed and predicted using FaceReader (FRE) software. The CATA and SCS showed similar results, with the 3100 K × 600 lx, 3100 K × 1000 lx and 6500 K × 600 lx lighting settings creating a relaxed, pleasant emotion in participants, the 6500 K × 1000 lx setting creating an excited, tense atmosphere, and the low illumination level settings of 3100 K × 250 lx and 6500 K × 250 lx made participants feel tired and frustrated. The results of the objective emotion analysis indicate that the FRE was able to effectively identify differences in participants' emotions in response to different lighting settings and was consistent with the results of participants' subjective emotion reports. This laboratory study validates that the three methods can effectively assess the enclosed space lighting settings, and provides a reference for further research on the enclosed space lighting settings and emotional monitoring of workers in the future.

Reflections on Carroll Izard’s Contributions: Influences on Diverse Scientific Disciplines and Personal Recollections

Carroll Izard’s theoretical and empirical work has played a preeminent role in energizing the renascence in the study of the emotions and emotional development in normality and pathology. A brief historical overview of his career is presented. Izard’s differential emotions theory (DET) has exerted influence in a number of domains and disciplines. Illustrations are provided from research and prevention in developmental psychology and developmental psychopathology. Personal recollections of Cal Izard are provided showing that Izard is not only an influential theoretician and researcher, but also a wonderful emotional being.
