Chronobiology studies physiological variations due to the time of day, an unexplored factor in design research. This paper explores the effect of time of day on designers' physiological responses in idea generation. Convergent (CT) and divergent (DT) thinking, as building blocks of designing, are explored using pupil dilation as a proxy for cognitive load. Time of day and educational background are explored for engineering and industrial designers. Results show a larger pupil diameter in the afternoon than in the morning, especially for DT, with higher values for industrial designers.
The EmotionProbe: an exploration of design students’ emotions when designing
Hazar Taissier Marji, Paul Rodgers, Ross Brisco
University of Strathclyde, United Kingdom
The emotional experiences significantly impact students' design processes. This research presents the EmotionProbe, a design probe tool for capturing design students' emotions while designing. The tool allows simple data collection, offering important insights into the students' design experiences, introducing the spectrum of emotions that design students go through, and showcasing various analysis approaches, allowing for a richer understanding of the design's emotional dimension. The research highlights the need for an emotional tool supporting students' emotional well-being while designing.

This study explores design strategies that designers adapt in different design environments and assesses cognitive load associated with acquiring, comprehending, and implementing strategies in concept product design phase. The findings from qualitative and quantitative analyses show that the traditional design environment exhibits a greater intrinsic load, thereby fostering a greater diversity of ideas, design strategies, and solutions. The digitally-mediated design environment demonstrates extraneous load, resulting in a tendency towards similarity in ideas, design strategies, and solutions.
An EEG study to understand semantic and episodic memory retrieval in creative processes
Yuan Yin, Peter Childs
Imperial College London, United Kingdom
This study aimed to identify and compare the EEG activities associated with semantic and episodic memory retrieval during creative processes. Episodic and semantic memory induction studies were conducted and EEG was used to collect data. The results showed that (i) Episodic and semantic memory retrieval are related to the frontal lobe area; (ii) Semantic memory retrieval is evoked more swiftly compared with episodic memory retrieval (ii) Prior to episodic memory retrieval, semantic memory retrieval is evoked first.
Investigating differences in brain activity between physical and digital prototyping in open and constrained design tasks

This article presents an fNIRS experiment investigating cognitive differences between physical and digital prototyping methods in designers (N=25) engaged in open and constrained design tasks. Initial results suggest that physical prototyping yields increased hemodynamic response (i.e., brain activity) compared to digital design, and that constrained design yields increased hemodynamic response compared to open design, in the prefrontal cortex. Further work will seek to triangulate results by investigating potential correlations to design processes and design outputs.
