    "abstract": "The proposal that the interaction between a macroscopic body and its\nenvironment plays a crucial role in producing the correct classical limit in\nthe Bohm interpretation of quantum mechanics is investigated, in the context of\na model of quantum Brownian motion. It is well known that one of the effects of\nthe interaction is to produce an extremely rapid approximate diagonalisation of\nthe reduced density matrix in the position representation. This effect is, by\nitself, insufficient to produce generically quasi-classical behaviour of the\nBohmian trajectory. However, it is shown that, if the system particle is\ninitially in an approximate energy eigenstate, then there is a tendency for the\nBohmian trajectory to become approximately classical on a rather longer\ntime-scale. The relationship between this phenomenon and the behaviour of the\nWigner function post-decoherence (as analysed by Halliwell and Zoupas) is\ndiscussed. It is also suggested that the phenomenon may be related to the\nstorage of information about the trajectory in the environment, and that it may\ntherefore be a general feature of every situation in which such environmental\nmonitoring occurs.",
