Changing viewpoints during dynamic events.

The connection of various viewpoints of a visual dynamic scene can be realised in different ways. We examined if various presentation modes influence scene recognition and cognitive representation type. In the learning phase, participants saw clips of basketball scenes from (a) a single, unvaried viewpoint, or with a change of viewpoint during the scene, whereby the connection was realised (b) by an abrupt cut, or (c) by a continuous camera move. In the test phase, participants had to recognise video stills presenting basketball scenes from the same or differing viewpoints. As expected, cuts led to lower recognition accuracy than a fixed unvaried viewpoint, whereas this was not the case for moves. However, the kind of connection between two viewpoints had no influence on the viewpoint dependence of the cognitive representation. Additionally, it was found that the amount of viewpoint deviation seemed to influence the overall conservativeness of participants' reactions.
