Monocular patching might improve perceptual-attentional, not motor-intentional deficits in a patient with chronic post-stroke left spatial neglect. Performing a line-cancellation task, his omission errors were associated with a perceptual-attentional "where" deficit, while perseverative errors were associated with "aiming" motor-intentional bias. Contralesional patching had no effect on the omissions (p=0.871), whereas ipsilesional patching reduced left-sided omissions compared with the unpatched condition (p=0.016). Neither patching condition altered perseverative errors. Further research is needed to examine whether targeting treatments to spatial neglect symptoms (omissions, perseveration) results in improved outcomes.
A multidimensional scaling technique, INDSCAL, was used to investigate the underlying structure 18 behavioral and 18 nonbehavioral clinical psychologists gave to 73 symptomatic behaviors descriptive of a wide range of psychopathology. Two partially related dimensions seemed to account for the obtained configuration: Dimension 1 was labeled psychotic-neurotic, and Dimension 2 was labeled turning within oneself-turning to others. These dimensions are similar to those found in other studies. Only limited differences between behavioral and nonbehavioral raters in the structure they provided the diagnostic cues were observed, suggesting that the clinician's theoretical persuasion is not a critical discriminator of the way he views symptoms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
