  We numerically investigate the stability of four-dimensional asymptotically
anti-de Sitter ($AdS_4$) spacetime for a class of nonminimally coupled scalar
field theories. In particular, we study how the coupling affects the formation
of black holes and transfer of energy to different spatial/temporal scales. We
conclude by detailing the well-known analogy between the nonminimally coupled
scalar-field stress-energy tensor and that of a viscous relativistic fluid, and
discuss the limitations of that analogy when it is applied to anisotropic
scalar field configurations in asymptotically $AdS$ spacetimes.
