Recognition and naming of object-drawings by men with focal brain wounds

Abstract

SUMMARY The ability to name object-drawings, measured by score and response latency, was examined in men with chronic, focal brain lesions due to missile injury. The group with left hemisphere lesions was significantly impaired on both measures and this impairment was clearly related to the incidence of clinically detectable dysphasia. In contrast, the impairment of the bilateral group was not closely associated with dysphasia; it was characterized by long response latencies which exceeded the sum of unilateral deficits in the task. Analysis of response errors showed that both misnaming and misidentification occurred but were often dissociated. Difficulty in naming was noted in men with lesions involving the left temporal lobe. Misidentification was not common; it occurred more frequently in the bilateral group, in men with lesions of the occipital areas of the brain. Dissociated deficits were also noted within the group of men with residual dysphasia.The peculiar difficulty which aphasic patients experience when asked to name objects has been known and used in clinical testing, almost from the time when disorders of speech resulting from cerebral lesions were first recognized as clinical entities. Broadbent (1884) reported it as a salient feature of the language breakdown in a patient with cerebrovascular disease predominantly affecting the territory of the middle cerebral artery; and several authors, including Kinnier Wilson ), Symonds (1953), and Brain (1961 have noted its special association with temporal-lobe disorder. Among groups of neurological patients with dysphasia, the symptom may be related to the size of the lesion and the extent of temporal-lobe involvement (H6caen and Angelergues, 1965).In residual asphasia after trauma naming difficulties are often less severe. Nevertheless, Marie and Foix (1917), in their study of veterans of the first world war, commented that this symptom had persisted as the most characteristic feature some months after injury. Thirty years later, Schiller (1947) also noted the prevalence of residual naming difficulties in a group of dysphasic ex-servicemen. He did not, however, find any connection between the symptom and the presumed site of the lesion, concluding that 'this essential feature is the least valuable for localization'.

Remembering a name: Neuropsychological validity studies and a computer proposal for detection of anomia

“…Also, using the selected CNT, we developed the CACNE, in which both spontaneous performance and cued performance were designed to detect anomia in interaction with environmental interventions. The present results also showed that the inconsistencies observed in CNT studies regarding either the involvement of the dominant hemisphere, or the detection of anomia in certain disorders, [7][8][9][10][11][12][13]46 were probably due to the presence of anomia in almost 50% of the patients with lesions to the right hemisphere. Thus, the CNT administered to patients with bilateral damage, which had undergone most validity studies, are more likely to have validation problems because these patients are usually compromised across a range of processes that affect naming.…”

Formal Schooling Influences Two- but Not Three-Dimensional Naming Skills

“…In neuropsychological research on clinical populations, visually related errors have been associated with poor functioning of the visual recognition system, while language related errors indicate a disruption of the language network involved in the naming task. Evidence from patients with visual agnosia also indicates that the visual characteristics of the stimuli (e.g., drawings/photos vs objects) have an influence on the error pattern during visual naming (Davidoff and De Blesser, 1993;Newcombe et al, 1971). Patients that dissociate in performance on drawings vs objects producing mostly visual errors indicate a deficit in the visual recognition system, and if additional perceptual information is provided the performance improve significantly.…”
