Abstract

This study integrates niche construction theory and cultural evolution theory to model emotional dynamics using Generative Adversarial Networks (GANs). Based on empirical data from 155 participants across five hypothetical cultural evolution stages, we developed a Research Based Emotion Evaluator and conditional GAN system with lambda-scheduling. Statistical analysis revealed that six out of eight basic emotions showed statistically significant stage differences (p < .01), corresponding to a 75% success rate in detecting effects, with negative emotions suppressed and positive emotions increasing through cultural progression. lambda-scheduling effectively balanced adversarial and feature-based learning, transitioning optimally at generation 120. Fourth stage environments showed emotional convergence with prominent expectation and reduced joy intensity, suggesting “stress elements” in advanced cultural evolution. Our computational validation demonstrates successful reproduction of empirical patterns, establishing GANs as viable tools for cultural evolution research and providing quantitative evidence for niche construction theory’s dual nature.
