We hypothesized that this difficulty could be due to the failure of right brain damage patients to develop well-matched models of the world.Our motivation is the idea that to navigate uncertainty, humans use models of the world to direct the decisions they make when interacting with their environment.Jensen S, Boley D, Gini M, Schrater P (2005) Rapid on-line temporal sequence prediction by an adaptive agent. In: Proceedings of the 4th International Joint Conference on Autonomous Agents and Multiagent Systems (pp. Rescorla RA, Wagner AR (1972) A theory of pavlovian conditioning: Variations in the effectiveness of reinforcement and nonreinforcement. Thankfully, technological leaps have opened a new, albeit virtual, world to psychologists.
Right brain damaged patients show impairments in sequential decision making tasks for which healthy people do not show any difficulty.
Additionally, during a spatial visualisation task (which is related to executive functioning and not STM or WM) concurrent executive suppression impaired performance indicating that the effects were due to common demands on the central executive and not short-term storage.
The researchers concluded with the explanation that the central executive employs cognitive strategies enabling participants to both encode and maintain mental representations during short-term memory tasks.
Recollection of spatial details is a top-down procedure that requires an individual to recall the superordinate features of a cognitive map, followed by the ordinate and subordinate features.
Thus, two spatial features are prominent in navigating a path: general layout and landmark orienting (Kahana et al., 2006).
