Significant relationships (Table 1, Figure 7) between personality traits, other individual traits (body weight or age), generic experience (flap lid and slide lid puzzles only), mechanistic behaviors (work time, functional behavior time, behavioral diversity, or behavioral flexibility), and problem-solving performance (time to first solve). The significant drivers of time to first solve for each puzzle type include (a) Dog treat toy (n = 10): (i) work time; (b) Flap lid (n = 12): (i) functional behavior time, (ii) behavioral flexibility, and (iii) mobility via its effect on functional behavior time; and (c) Slide lid (n = 11): (i) age.
