Conation, which involves the ability to apply oneself diligently and productively to the completion of a task over time, was compared in groups with and without evidence of brain damage. Both groups were administered tests that ranged from tasks that were presented by an examiner one item at a time (minimal conation), to a task that required the subject to(More)
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)
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 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)
Recent reassessment of the literature on the shaken baby syndrome (SBS) has revealed a lack of scientific evidence and understanding of all aspects of the syndrome. In particular, studies have been unable to clarify the mechanisms of injury, indicating that impact, rather than shaking alone, is necessary to cause the type of brain damage observed.(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)
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 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)
