Previous research by Palmisano, Gillam and Blackburn (2000) found that adding coherent perspective jitter to constant velocity radial flow improved visually induced illusions of self-motion (known as vection). This was a surprising finding, because unlike pure radial flow, this jittering radial flow should have generated sustained visual-vestibular conflicts - previously thought to always reduce/impair vection. The current experiments attempted to ascertain the essential stimulus features for this jitter advantage for vection by examining three novel types of jitter display. While adding incoherent jitter to radial flow was found to impair vection, adding coherent non-perspective jitter had little effect on this …

The charge-on-spring method is used to develop a rigid, three-site, polarizable water model, a noniterative and a self-consistent version. In this method, the polarizability is taken into account by a variable separation of charges on selected polarizable centers. One of the pair of polarization charges resides on a polarizable center, while the other one is treated as an additional particle attached to the polarizable center by a parabolic restraint potential. The separation is calculated in response to the instantaneous electric field. We parametrized two models which are based on noniterative and self-consistent versions of the method, respectively. We computed several …
