Visual neglect can be object-based or scene-based depending on task representation.

Three patients with visual neglect were tested on their ability to detect target letters at ipsilesional and contralesional locations on a monitor, and at different locations within large shapes on the monitor. When patients were asked to detect targets within the entire monitor, they showed neglect for all the contralesional hemifield. In contrast when they were asked to detect targets within a particular object, they showed object-based neglect.

Auditory extinction: the effect of stimulus similarity and task requirements.

Auditory extinction was examined in six patients with right hemisphere lesions, using an auditory double simultaneous stimulation task using letters spoken in male and female voices. Patients had to detect where the stimuli were located, and identify either the letter or the voice (the task-relevant dimension). Auditory extinction was greatest when the two stimuli were the same on the task-relevant dimension, paralleling previous studies of visual extinction.

Visual attention and word recognition in stroop color naming: is word recognition "automatic"?

In Stroop color naming, color targets were accompanied by a color word or a color word plus a neutral word that reduces or "dilutes" the Stroop effect. Abrupt-onset cues called the focus of attention to one stimulus or another. Cuing influenced the size of the Stroop effect but never eliminated it.
