Presumptions about the functions of the frontal lobes, and the sensitivity and specificity of certain tests to measure frontal lobe functions, are having a substantial influence on both clinical and research conclusions. In this paper the authors examine the details of the studies that have contributed to these presumptions, and find that the evidence to(More)
Recent reports in the literature have explored differential relations between age and education and psychological test results in groups with brain damage and groups without brain damage. In several investigations, both adults and children have been studied, using Wechsler Adult Intelligence Scale values and subtest scores as welt as tests that are(More)
Sensory-perceptual and motor functions are closely dependent on the integrity of the brain and nervous system. Standardized tests have been developed to assess these functions, but such tests are not routinely used to evaluate children who are suspected of having a neuropsychological basis for their difficulties. Higher-level functions (such as verbal and(More)
The interaction and relationships between neuropsychological tests (which are principally oriented to intellectual and cognitive abilities) and tests of personality and emotional status are complex, but nevertheless important in the clinical assessment of brain-damaged persons. Are indications of emotional disturbances to be expected as a direct consequence(More)
The research literature indicates that the great majority of persons who sustain any initial neuropsychological impairment from a mild head injury recover in 1 to 3 months. Nevertheless, clinicians report that some persons with a mild head injury demonstrate signs and report symptoms suggesting that they have sustained permanent brain damage. Although this(More)
This study was designed to explore the possibility of using a brief neuropsychological test for broad-band initial screening of children with academic problems who might have neuropsychological deficits that should be more completely evaluated. Part B of the Trail Making Test was selected as the instrument for investigation. Three groups of children, aged(More)
The aim of this study was to develop a short screening battery that would predict whether older children would show significant impairment on comprehensive neuropsychological testing. The screening battery was subdivided into two phases. Phase 1 was intended as a broad catchment effort; Phase 2 was designed to be a more detailed and selective procedure.(More)
The consistency of responses to individual items of the Wechsler Information, Comprehension, Arithmetic, Similarities, and Vocabulary subtests on two separate testings were compared for two groups of 20 head-injured subjects. One group of subjects was involved in litigation to recover damages for deficits allegedly resulting from the head injury; the other(More)
Reports in the literature have suggested that the neuropsychological effects of mild head injury are selective, represented by impairment of attention, information processing, and memory, and that evaluations with comprehensive and standard test batteries are likely to miss such deficits. The present study compared groups of individuals with mild head(More)
Hom and Reitan (1982) reported findings with respect to sensorimotor deficits in groups with lateralized cerebral lesions, but evaluated the results only within a framework that related cerebral dominance to deficits that resulted from lateralized lesions. Some of the variables they studied, however, depend upon evidence of retention of functions by one(More)
