ABSOLUTE MEASUREMENT OF THE VIBRATORY THRESHOLD

Archives of Neurology And Psychiatry, 1951
FOR MANY years the appreciation of vibration has been used in the study and diagnosis of various neurologic disorders. 1 Up to the present time both the tuning fork and electrical vibrators 2 have been used for such determinations. However, while the latter represent a vast improvement over the former, the attendant errors in both have restricted their

Screening Talent: Absolute or Percentile Thresholds?

SSRN Electronic Journal, 2020
Matching talents to tasks is an important part of job design. Organizations routinely use performance thresholds to group agents by talent. We see thresholds defined both in terms of an individual's own performance (absolute value) and in terms of peer performance (percentiles).

Absolute Threshold for Extremely Wide Fields

Journal of the Optical Society of America, 1958
The absolute visual threshold for an area 40° by 100° visual angle at a color temperature of 2050°K was obtained for seven observers. Two conditions were used, (1) turning the light on and (2) turning the light both on and off before a judgment was made. The average threshold for the six observers in the 24–36 year age range was 2.35 log μμL.

Threshold Analysis for Absolute Productivity

2021
This chapter explains how an adaptation to the TI method can allow more direct comparisons across institutions through a calculation of absolute productivity. The tutorial builds from the case study used in Chaps. 4 and 5. It shows how a feature scaling technique can open the door for absolute productivity calculation and applies threshold analysis to ...

THE ABSOLUTE THRESHOLD OF ELECTRIC SHOCK

British Journal of Psychology, 1962
Thresholds for electric shock were obtained under twelve conditions. Three types of stimulus were used; constant voltage, constant current, and constant power. These, combined with three sizes of electrode, gave nine conditions in all. A further three thresholds were obtained using the three types of stimulus and the medium size electrodes, with the ...

Absolute Behavioral Auditory Thresholds in Mice

The Journal of the Acoustical Society of America, 1963
The experiment was designed to obtain behavioral measures of absolute auditory thresholds and to compare them with cochlear potentials and with single-unit eighth-nerve-fiber thresholds. Mice were selected because certain strains display pathological conditions that appear similar to some congenital auditory defects found in humans.

Near threshold absolute TDCS: first results

Zeitschrift für Physik D Atoms, Molecules and Clusters, 1992
A new method, and first results for an impact energy 2 eV above the threshold of ionisation of helium, are presented for the measurement of absolute triple differential cross sections (TDCS) in a crossed beam experiment. The method is based upon measurement of beam/target overlap densities using known absolute total ionisation cross sections and of ...

Absolute energy calibration of neutron thresholds

Nuclear Physics, 1966
Abstract A newly developed low background system for measuring neutron threshold energies above 5 MeV was used in conjunction with a 180° annular magnetic spectrometer to perform absolute measurements of four neutron threshold energies covering the energy range from 3 to 9.5 MeV.

Absolute Threshold for Electric Shock

Nature, 1962
FOR some time it has been suspected that the most relevant parameter when using electric shock as a stimulus is the applied wattage. Forbes and Bernstein1, Gilmer2, Hill et al.3, Campbell and Teghtsoonian4, Green5, all found evidence to support this contention.

Absolute threshold: analysis in terms of uncertainty

Journal of the Optical Society of America, 1981
Uncertainty, the inability to know or to make use of information regarding the parameters of a luminance stimulus to be detected, is herein shown by simulation to (1) steepen the frequency-of-seeing curve and (2) cause psychophysical estimates of quantum efficiency to be too low.
