Study 1, Task 2 performance across two conditions. Independent raters counted the number of ideas; and assessed the quality of these ideas on a five-point scale with endpoints 1 for “poor” and 5 for “excellent” in Task 2 (Alternative Uses Test; AUT). Participants who collaborated with GenAI in Task 1 generated ideas of higher quality in the subsequent human-solo work in Task 2, compared to participants who worked solo in both tasks. No significant difference was found between the two groups in terms of the number of ideas generated in Task 2. N = 352. ** p < .01. Error bars indicate ± 1 SEM.
