Correlating Design Performance to Eeg Activation: Early Evidence From Experimental Data

Abstract

This paper presents an EEG (Electroencephalography) study that explores correlations between the neurophysiological activations, the nature of the design task and its outputs. We propose an experimental protocol that covers several design-related tasks: including fundamental activities (e.g. idea generation and problem-solving) as well as more comprehensive task requiring the complex higher-level reasoning of designing. We clustered the collected data according to the characteristics of the design outcome and measured EEG alpha band activation during elementary and higher-level design task, whereas just the former yielded statistically significant different behaviour in the left frontal and occipital area. We also found a significant correlation between the ratings for elementary sketching task outcomes and EEG activation at the higher-level design task. These results suggested that EEG activation enables distinguishing groups according to their performance only for elementary tasks. However, this also suggests a potential application of EEG data on the elementary tasks to distinguish the designers' brain response during higher-level of design task.

Comparing EEG Brain Power of Mechanical Engineers in 3D CAD Modelling from 2D and 3D Representations

“…The design of the experiment carried out to answer the research question was guided by already published experimental studies concerned with the electrophysiological investigation of human behaviour in design (for instance, Li et al (2021) and Vieira et al (2020)). The experimental procedure (Sect 3.2) enables the exploration of differences in engineers' brain activity during two 3D CAD modelling tasks (Sect 3.3).…”

“…The experimental procedure (Sect 3.2) enables the exploration of differences in engineers' brain activity during two 3D CAD modelling tasks (Sect 3.3). While the experimental setup (Sect 3.4) is originally developed for this research question, the data pre-processing (Sect 3.5) elaborates and adapts the pipeline suggested by Li et al (2021) so that it produces results for data analysis (Sect 3.6).…”

“…The EEG data processing was conducted in Matlab with the EEGLAB toolbox (Delorme and Makeig, 2004). An original script for data processing was developed according to the pipelines described by Li et al (2021) and Vieira et al (2020). In the first step, DC offset specific for Emotiv EPOC+ devices was removed with the infinite impulse response (IIR) filter.…”

An Attempt to Grasp Resonance during Co-Creation with Biosignal Indicators

“…The interest of this study is to grasp a resonance quantitatively with multimodal biosignal indicators as an interpersonal cognitive state during collaborative design which could enhance individual creativity and develop a co-creation phenomenon. The studies with EGG to grasp quantitatively interpersonal relationships (Motomura et al, 2015) and creative states (Li et al, 2021;Vieira et al, 2020) has been very active in recent years. There have been recognized limitations of measuring creative states with EEG; it allows so limited movements to measure that its experimental protocol cannot represent the intended situation in appropriate scale; it is difficult to interpretate more than its measured activity.…”
