A series of experiments was carried out to examine the effect of curvature on haptic judgments of extent in sighted and blind individuals. Experiment 1 showed that diameters connecting the endpoints of semicircular lines were underestimated with respect to straight lines, but failed to show an effect of visual experience on length judgments. In experiment 2 we tested are lengths. The effects of...

OBJECTIVE The purpose of this study was to establish normative data on spherical grip strength of children 3 to 6 years of age with the Martin Vigorimeter. METHOD Two hundred twenty-five preschoolers in the Kalamazoo, Michigan, area were tested with standardized positioning and instructions. The mean of three trials for each hand was used as the grip-strength score. A repeated measure design ...

At 3 a.m. 01116th ultimo a woman was brought to the dispensary by the Police from a village some 25 miles away. Throwing herself between two men who were fighting she received a swordthrust midwnv between the umbilicus and ensiform proc. The cut was 2 inches long, clean, and .oblique from below up and inwards. A coil of small gut protruded ; over this a piece of cotton wool had been placed. Thi...

It has been widely reported that men have a lower ratio of the 2nd and 4th human finger lengths (2D : 4D). Size-scaling ratios, however, have the seldom-appreciated potential for providing biased estimates. Using an information-theoretic approach, we compared 12 candidate models, with different assumptions and error structures, for scaling untransformed 2D to 4D lengths from 154 men and 262 wom...

ON the following pages I describe the nature of the tooth rudiments'in the very young embryo of P h y s e t e r m a c r o c e p h a l u s , whose general external characters I have already commented upon and figured (Beddard, 1). Since the material upon which I have worked is, so far as I am aware, a unique specimen only 4 | inches long, I am particularly grateful to the Curator of the Durban M...

BACKGROUND Previous research has revealed that the ratios of the lengths of various pairs of human fingers differ in males and females. METHOD In an attempt to determine whether parallel sex differences also exist in the relative lengths of human metacarpals and metatarsals, the lengths of the metapodials for both hands and both feet were measured in a collection of human skeletons. For each ...

Objectives The goal of this study was to quantify external and internal anatomical characteristics of the foal foot throughout the first year of age. Methods Digital radiographs and photographs were taken bimonthly of the forefeet of nine Arabian foals, beginning at about 2 weeks of age until 12 months of age. Sixty-eight linear and angular variables were measured using NIH (National Institutes...

The patterns of muscle mass distribution along the lengths of limbs may have important effects on the mechanics and energetics of quadrupedalism. Specifically, Myers and Steudel (J. Morphol. 234 (1997) 183) have shown that fore- and hindlimb Natural Pendular Periods (NPPs) may affect quadrupedal kinematics and must converge to reduce locomotor energetic costs. This study quantifies patterns of ...
