| Neglect is syndrome that results from damage to the? | Right parietal cortex |
| Define 'Neglect'... | A neurological syndrome (often involving damage to the right parietal cortex) in which patients show a marked deficit in the ability to detect or respond to stimuli in the contralesional side of space |
| Neglect is a result of _____ parietal damage where as Balints' syndrome is a result of _____ parietal damage | Unilateral, bilateral |
| Name some common neuropsych assessments for Neglect | Line bisection, cancellation tasks |
| Neglect can affect different reference forms, what are these? | Personal space -> shaving, combing hair Peri-personal space -> near space, eating only have of food on a plate Allocentric -> centers on the object, only half of an object is seen |
| Who developed the peripheral cueing paradigm? | Posner, 1980 |
| In the peripheral cueing paradigm, what problem do Neglect patients have? | Issue of disengaging attention away from the ipsilesional side to the contralesional side. Seen when a cue points to the (right) good side but the target appears on the left |
| As Neglect is dynamic, what stages of Neglect can occur? | Acute stage - soon after injury, worse performance on tasks Chronic stage - deficits are reduced |
| In terms of brain imaging what evidence has been found in terms of activation and different reference forms? | Chechlacz et al., (2010) found that there was a differentiation between allocentric and egocentric neglect specifically in right temporal regions but an overlap in the TPJ (circuit breaker) |
| What is extinction? | A phenomenon where patients detect a single stimulus presented to one visual field (typically left) but fail to detect the same stimuli when another stimulus is presented simultaneously |
| Who found that left parietal patients have reduced saliency suppression? | Mevorach et al., (2009a) |
| If left parietal patients have larger RT's detecting global information when local information is salient than controls this suggests? | Left parietal patients have a deficit in being able to ignore salient distractors |
