Number of intervals (mean ± SEM) with manipulation for two videogame tasks and a foraging device during: (A) the initial observation period (0–20 min); and (B) the observation period 1 hour after device placement (60–80 min). Post-hoc tests showed that manipulation of the videogame system was significantly higher for both tasks in comparison to manipulation of the foraging device at the 1-hour observation period (*p < .05).
