Table 1.

Descriptive statistics for the mean and max semantic distance and subjective ratings of creativity for artificial intelligence (AI) and human participants averaged across all responses to the object probes.

	Group	Mean semantic distance	Max semantic distance	Mean subjective rating	Max subjective rating
Na	AI	33	33	33	33
	Human	256	256	256	256
Mean	AI	0.95	1.01	2.91	3.61
	Human	0.91	0.98	2.47	3.18
95% CI	AI	[0.94, 0.96]	[1.00, 1.02]	[2.77, 3.05]	[3.45, 3.77]
	Human	[0.90, 0.91]	[0.97, 0.99]	[2.41, 2.53]	[3.12, 3.25]
SD	AI	0.03	0.036	0.39	0.45
	Human	0.06	0.053	0.47	0.53
Min	AI	0.90	0.90	2.21	2.71
	Human	0.69	0.69	1.00	1.00
Max	AI	1.01	1.04	3.69	4.63
	Human	1.03	1.06	3.56	4.25

Theoretically the semantic distance may vary between 0 and 2, with higher scores indicating higher distance. The subjective ratings of creativity were made on 5-point scale (1 = not at all, 5 = very).

^aN for AI refers to the number of test sessions.
