Task alternation cost without task alternation: measuring intentionality.
A behavioral dissociation between intention and action was demonstrated by patient AF who sustained damage to the left-hemisphere including the basal ganglia. The patient was tested in a task switching paradigm involving two choice reaction-time tasks: SIZE (small/large) and SHAPE (circle/square). The last block in each of the two sessions involved only one task. AF switched tasks reasonably we...
متن کاملHippocampal Lesions Impair Rapid Learning of a Continuous Spatial Alternation Task
The hippocampus is essential for the formation of memories for events, but the specific features of hippocampal neural activity that support memory formation are not yet understood. The ideal experiment to explore this issue would be to monitor changes in hippocampal neural coding throughout the entire learning process, as subjects acquire and use new episodic memories to guide behavior. Unfort...
متن کاملDelayed Alternation 1 Running head: DELAYED ALTERNATION Prefrontal contributions to delayed spatial and object alternation: A PET study
Delayed alternation tasks are frequently employed as probes of frontal lobe functioning. In order to clarify the neural substrates of delayed alternation performance in humans, we measured regional cerebral blood flow with H20 PET in healthy subjects as they performed delayed spatial and object alternation. Consistent with the monkey lesion literature, increased dorsolateral prefrontal activity...
متن کاملEffects of Communication Methods on Communication Patterns and Performance in a Remote Spatial Orientation Task
An experiment was conducted to examine the impact of communication methods (text-only, audio-only, and audio-plus-video) on communication patterns and effectiveness in a 2-person remote spatial orientation task. The task required a pair of participants to figure out the cardinal direction of a target object by communicating spatial information and perspectives. Results showed that overall effec...
متن کاملConditioned discrimination of magnetic inclination in a spatial-orientation arena task by homing pigeons (Columba livia).
It has been well established that homing pigeons are able to use the Earth's magnetic field to obtain directional information when returning to their loft and that their magnetic compass is based, at least in part, on the perception of magnetic inclination. Magnetic inclination has also been hypothesized in pigeons and other long-distance navigators, such as sea turtles, to play a role providin...
