Forward and Backward Inference in Spatial Cognition
Figure 5
The task of decision making is to decide whether to make a left or a right turn (hence the question mark in the above graphic). Top Left: Locations on the route of the ‘left turn’ or north-west trajectory (red curve) Top Right: The markers A, B, C, D and E denote locations on the ‘right turn’ or north-east trajectory corresponding to time points and
respectively. Bottom: The log likelihood ratio (of north-east versus north-west),
, as a function of the number of time points along the trajectory.
