Tecwyn and Buchsbaum (2018) in this issue challenge the idea that dogs display a persistent gravity bias. In four experiments, they probed where dogs search for a ball after it is dropped into a tube. First, they replicated diagonal tube task experiments previously conducted with apes (Cacchione & Call, 2010) to investigate how auditory and visual information about the tubes influenced the dogs' search. Next, they examined how dogs' search shifted when the middle location was no longer an option. Third, they probed whether dogs' search could be explained by proximity between the reward's release point and the search locations (a condition depicted in Figure 1). Finally, they presented tasks in which any of the biases that might have guided them in the previous experiments (namely, gravity, middle position, or proximity to the point where the ball was dropped) could not guide their search.
