In Figure 1A, average latency decreased from 101.4 ± 6.1 seconds on Day 1 to 49.7 ± 8.9 seconds on Day 2 and 2.4 ± 1.0 seconds on Day 3. A Wilcoxon signed-rank test indicated a significant decrease in latency between the first and final training day of the Pick Up phase (W = 55.0, P = 0.001).

 

 

In Figure 1B, average latency decreased from 26.3 ± 14.9 seconds on Day 4 to 0 ± 0 seconds on Day 5. A Wilcoxon signed-rank test indicated a significant decrease in latency between the first and final training day of the Drop phase (W = 28.0, P = 0.008).

 

 

 

In Figure 1C, average latency decreased from 102.1 ± 7.2 seconds on Day 6 to 78.2 ± 7.0 seconds on Day 10. Intermediate average latencies of 81.5 ± 7.0 seconds, 90.1 ± 6.3 seconds, and 87.6 ± 7.1 seconds were observed on Days 7, 8, and 9, respectively. A Wilcoxon signed-rank test indicated a significant decrease in latency between the first and final training day of the Toy in Bin phase (W = 38.0, P = 0.037).

In Figure 2, Josie successfully completed an average of 80% of trials during the Pick Up phase, 90% of trials during the Drop phase, and 66% of trials during the Toy in Bin phase. Task completion success was highest during the Drop phase and lowest during the Toy in Bin phase.

In Figure 3, average engagement duration was 17.5 minutes during the Pick Up phase, 14.0 minutes during the Drop phase, and 17.6 minutes during the Toy in Bin phase. Engagement duration was lowest during the Drop phase and highest during the Toy in Bin phase.
