Table 1 Generalized linear mixed effect models showing the effects of fixed effects on the number of attempts to succeed when both personality types and intra-individual variabilities (IIVs) of both predators Portia labiata and prey Cosmophasis umbratica were included in the models (n = 39).

Fixed effects	Estimate	SE	Z	P
Intercept	0.734	0.122	6.017	<0.0001
Trial number	0.030	0.118	0.256	0.798
Body size ratio ^*	−0.063	0.129	−0.491	0.623
Predator aggressiveness	−0.007	0.119	−0.605	0.545
Predator IIV	0.165	0.126	1.314	0.189
Prey boldness	0.142	0.154	0.918	0.359
Prey IIV	−0.134	0.149	−0.903	0.366
Predator aggressiveness × prey boldness	−0.055	0.159	−0.343	0.731
Predator IIV × prey IIV	−0.096	0.172	−0.558	0.577
Predator IIV × prey boldness	0.087	0.107	0.813	0.416
Predator aggressiveness × prey IIV	−0.321	0.124	−2.580	0.009

^*Body size ratio = carapace width of prey/carapace width of predator. Bold indicates the significant value. The full model was step-wise simplified by dropping the least significant interaction term.
