Four groups of eight 4-month-old infants were each habituated to one of four displays consisting of a grating of either low (0.4 cycle deg(-1) or high (1.2 cycles deg(-1) spatial frequency, whose central portion was covered up with a horizontal occluder which was either narrow (1.33 deg) or broad (4.17 deg). Posthabituation displays consisted of a complete(More)
Measurements of sound localization in the lateral dimension were taken with or without head movements when the observer wore the electronic pseudophone in an anechoic chamber. Tones of various frequencies as stimuli were presented from the loudspeakers located on the horizontal plane of the observer's head and on the circle, 2 m in diameter, around the(More)
One of the newest CT application technologies is cardiac synchronized image reconstruction. In this technology, evaluation of time-resolution is very important. We developed a method of measuring time-resolution in cardiac synchronized reconstruction, and evaluated various scanning protocols. In our experiment, ECG-gated scanning was done by multi-slice CT(More)
