Maximising creativity requires an enriched imagination that uses all five senses. This study explored the effects of a reduced visual–auditory multisensory stimuli environment on creativity. Nineteen participants took the Alternative Uses Test (AUT) under the nine decreased visual–auditory multisensory stimuli conditions. Fluency and originality were evaluated as a part of the creativity assessment. The number of ideas from the AUT determined the fluency level, and the three judges’ evaluations determined originality. A study on associative conceptual network analysis explored the word associations of selected nouns from the AUT under nine reduced visual–auditory multisensory stimuli experimental conditions, revealing outdegree centrality scores to evaluate creative potential. The results suggest that the decreasing visual stimuli inhibit fluency whereas auditory stimuli do not, and that originality is enhanced when stimuli are reduced, whether visual or auditory, unless there is a notable divergence between the visual and auditory conditions. These results highlight the importance of perceptual focus and cognitive load regulation in fostering creative potential.
