Criteria for Impairment for Each Type of Neglect

Criteria for impairment, viewer-centered neglect 
1. Significantly more errors on stimulus presentation in the left body field versus the right body field on at least one of the following tasks 
 a. Line cancellation 
 b. Gaps 
 c. Bells 
 d. Line bisection 
2. AND/OR Significantly more errors on the left versus the right side of the page on at least one of these tasks administered at midline 
 a. Ogden scene 
 b. Gap detection task 
 c. Passage reading 
 
Criteria for impairment, stimulus-centered neglect 
1. Significantly more errors on the left versus the right side of the page on at least one of the following tasks, presented both at midline of the patient's body AND in at least one of the other body fields (LBF or RBF) 
 a. Line cancellation 
 b. Bells 
2. AND/OR Significantly more errors on the left side of the stimulus versus the right side of the stimulus on at least one of the following tasks 
 a. Ogden scene (left side of objects in scene vs. right side of objects in scene) 
 b. Gap detection task (left side of circle vs. right side of circle) 
 c. Sentence reading (left side of word vs. right side of word) 
 d. Gaps 
 
Criteria for impairment, object-centered neglect 
1. Significantly more errors on the contralesional side versus the ipsilesional side of the canonical representation of words in the vertical word reading task 
2. AND/OR Significantly more errors on the contralesional side versus the ipsilesional side of words in single word reading AND in mirror-reversed word reading 
3. AND/OR Significantly more errors on the contralesional side versus the ipsilesional side of words in recognition of oral spelling
