Transfer of Learning between Hemifields in Multiple Object Tracking: Memory Reduces Constraints of Attention
, 2013
"... Many tasks involve tracking multiple moving objects, or stimuli. Some require that individuals adapt to changing or unfamiliar conditions to be able to track well. This study explores processes involved in such adaptation through an investigation of the interaction of attention and memory during tra ..."

versus processes of memory. Here we show that when individuals are trained to track a unique pattern of movement in one hemifield, that learning can be transferred to the opposite hemifield, without any evidence of hemifield independence. However, learning is not influenced by an explicit strategy
From reorienting of attention to biased competition: Evidence from hemifield effects
"... When a distractor was presented simultaneously with or directly following a target, it produced more interference when it was presented in the same visual hemifield as the target than when it was presented in the opposite visual field. This result is interpreted in terms of biased competition; there ..."

PSYCHOLOGICAL SCIENCE Research Article ATTENTIONAL ENHANCEMENT OPPOSITE A PERIPHERAL FLASH REVEALED USING CHANGE BLINDNESS
"... Abstract—We describe a new method for mapping spatial attention that reveals a pooling of attention in the hemifield opposite a peripheral flash. Our method exploits the fact that a brief full-field blank can interfere with the detection of changes in a scene that occur during the blank. Attending t ..."

In experiment 1 subjects were instructed to perform pointing responses toward targets that were located either in the same or the opposit ..."

The direction of the responses was indicated by the shape of the imperative stimulus. Reaction time (RT), movement time, and
Nasotemporal ERP differences: evidence for increased inhibition of temporal distractors

To investigate whether this nasotemporal asymmetry reflects a genuinely attentional bias, we recorded event-related potentials in a task where participants identi-fied a color-defined target di ..."

To dissociate the processing of stimuli in nasal and temporal visual hemifields, an eye-patching procedure was used. Targets triggered N2pc components that marked their attentional

Commentary Microsaccade Orientation Supports Attentional Enhancement Opposite a Peripheral Cue
"... paradigm to map the redistribution of spatial attention in response to a peripherally flashed cue. The probability of change detection at a given location was used as a measure of attention allocation. Using this measure, a ‘‘hot spot’ ’ of attention (i.e., close to perfect change detection) was fou ..."

) was found along the cue-fixation axis. This hot spot ex-tended in the hemifield opposite the cued location. Here we show that an analysis of fixational eye movements in a spatial-cuing paradigm supports this important finding. During fixation of a stationary target, micromovements of the eyes occur
