Object tracking: absence of long-range spatial interference supports resource theories.
Attentional tracking of a moving target can be impaired by the presence of a second object, particularly if the second object is another target. One potential cause of this impairment is spatial interference. But the impairment may alternatively reflect a need to divide a finite attentional resource among targets. The performance cost of splitting a resource among targets should not be affected...
متن کاملEEG Correlates of Attentional Load during Multiple Object Tracking
While human subjects tracked a subset of ten identical, randomly-moving objects, event-related potentials (ERPs) were evoked at parieto-occipital sites by task-irrelevant flashes that were superimposed on either tracked (Target) or non-tracked (Distractor) objects. With ERPs as markers of attention, we investigated how allocation of attention varied with tracking load, that is, with the number ...
متن کاملAttention Modulates Spatial Precision in Multiple-Object Tracking
We present a computational model of multiple-object tracking that makes trial-level predictions about the allocation of visual attention and the effect of this allocation on observers' ability to track multiple objects simultaneously. This model follows the intuition that increased attention to a location increases the spatial resolution of its internal representation. Using a combination of em...
متن کاملDifferential neuronal representation of spatial attention dependent on relative target locations during multiple object tracking.
Humans can simultaneously track multiple moving objects with attention. The number of objects that can be tracked is known to be larger when visual stimuli are presented bilaterally rather than presented unilaterally. To elucidate the underlying neuronal mechanism, we trained monkeys to covertly track a single or multiple object(s). We found that neurons in the lateral prefrontal cortex exhibit...
متن کاملObject Detection and Tracking in Range
Sequences by Separation of Image Features Esther B. Meier, Frank Ade Abstract| We propose a new approach for a driver assistance system based on range image sequences to increase the safety on motorways. This control system is capable of automatically keeping the car at an adequate distance or warning the driver when he gets too close to other cars. The knowledge of the sensor geometry with res...
