The Divided Visual Field Paradigm is an experimental technique that involves measuring task performance when visual stimuli are presented on the left or right visual hemifields. If a visual stimulus appears in the left visual field (LVF), the visual information is initially projected to the right cerebral hemisphere (RH), and conversely, if a ...

The visual field is "that portion of space in which objects are visible at the same moment during steady fixation of the gaze in one direction"; [1] in ophthalmology and neurology the emphasis is mostly on the structure inside the visual field and it is then considered “the field of functional capacity obtained and recorded by means of perimetry”.
The Posner cueing task, also known as the Posner paradigm, is a neuropsychological test often used to assess attention. Formulated by Michael Posner , [ 1 ] it assesses a person's ability to perform an attentional shift .
This was termed the inhibition of return paradigm: “An inhibitory effect produced by a peripheral (i.e., exogenous) cue or target”. [24]: 1 Klein hypothesised that inhibition of return is a mechanism that allows a person not to re-search in previously searched visual fields as a result of “inhibitory tags”. [25]

The visual hemifield contralateral to a lesion in the lingual or fusiform gyrus is the one that appears grey, while the ipsilateral visual hemifield appears in colour. [13] The variance in symptoms emphasizes the need to understand the architecture of the colour centre in order to better diagnose and possible treat cerebral achromatopsia.
A variant of this paradigm is the filter paradigm. In this paradigm participants are asked to attend to a certain part of the visual field and to not pay attention to or "filter out" the rest of the visual field. Blocks of stimuli are presented one at a time in both attended and unattended space.
