Preface There is hardly a field in psychology in which the effects of signal detection theory have not been felt. The authoritative work on the subject, Green's & Swets' Signal Detection Theory and Psycho-physics (New York: Wiley) appearedjn 1966, and is having a profound influence on method and theory in psychology. All this makes things exciting but(More)
The present experiments were performed to determine the site of action (hypothalamic or hypophyseal) and the mechanism (dopaminergic or serotonergic) by which morphine increases PRL in monkeys (Macaca mulatta and Macaca nemestrina). To determine the site of action, 9 mg morphine were injected iv to four intact and four pituitary stalk-sectioned monkeys. PRL(More)
The version of the acetabular and femoral components in 111 primary total hip arthroplasties was prospectively evaluated intraoperatively by the surgeon and compared with postoperative computed tomography (CT) scan measurements. Intraoperative estimations by the surgeons for acetabular and femoral components were all within 10 degrees to 30 degrees(More)
The extent to which auditory, tactile, and visual perceptual representations are similar, particularly when dealing with speech and speech-like stimuli, was investigated. It was found that comparisons between auditory and tactile patterns were easier to perform than were similar comparisons between auditory and visual stimuli. This was true across a variety(More)
Nonphyseal supracondylar fractures of the femur are considered to be uncommon in children and have received little attention in the literature. A retrospective review of femoral fractures in children at the authors' institution was undertaken to ascertain the incidence of supracondylar femoral fractures, the influence of associated musculoskeletal(More)
The development of lateral tibial torsion in the paralysed lower limb is well documented, but its pathogenesis is poorly understood. This paper attempts to provide an explanation for its development when it is associated with a varus or equinovarus deformity of the hindfoot. Correction of the lateral tibial torsion by supramalleolar derotation tibial(More)
