Visual Identification Rate in Search of a Missing Stimulus
Perceptual and Motor Skills, 1989Subjects searched for a digit which was not presented in an array of nine different digits. The identification rate was estimated from the percent correct. Well-trained subjects identified 6.5 digits with a 50-msec. exposure. This fast identification rate was expected from our procedure using a single answer, an inconsistent target, and equal ...

Rate of Habituation and Visual Memory in Infants
Child Development, 1976This study investigated 17-week-old infants' response to discrepancy as a function of rate of habituation. 36 subjects were repeatedly shown a pattern containing 4 geometric shapes until they reached a proportional criterion of habituation: each infant's fixation time had to decrease by at least 50%.

Visual Sensitivity to the Rate of Electrically Produced Intermittence*
Journal of the Optical Society of America, 1956Temporal resolution of the neural and cortical components of vision was studied with periodic electric stimuli as a means of by-passing the photochemical retina. Difference-limens for discriminating the frequency of the faint flashes of light due to the passage of current through the eye were obtained at 13 frequencies between 5 and 45 cps.

Infant Differences in Rate of Visual Encoding
Child Development, 1991To clarify the basis for infant differences in rate of visual encoding, the eye movements of a sample of 9 12-week-old infants were recorded throughout an encoding experiment. Results showed that the more slowly encoding infants scanned less extensively over the stimulus, often spent extended intervals in the continuous inspection of one part of the ...

Validity and Reliability of Visual Ratings of the Vertical Jump
Perceptual and Motor Skills, 1999The validity and reliability of visual estimates of the kinematics of the vertical jump as would be common in qualitative analysis of human movement was studied. Sagittal plane videotapes of 12 females performing vertical jumps were rated on two occasions by three samples of subjects: 6 basketball coaches, 10 kinesiology students, and 5 kinesiology ...

Ultrasonic Visualization in Determination of Tumor Growth Rate
JAMA: The Journal of the American Medical Association, 1973The growth rate of intracranial neoplasms has been studied extensively in three patients with the use of ultrasonic visualization methods. Normal and abnormal structural details in their brains have been compared to the brain structure of one patient without neoplastic disease. These patients' brains were scanned ultrasonically through the healed scalp,

Measuring visual saliency by Site Entropy Rate
2010 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2010In this paper, we propose a new computational model for visual saliency derived from the information maximization principle. The model is inspired by a few well acknowledged biological facts. To compute the saliency spots of an image, the model first extracts a number of sub-band feature maps using learned sparse codes.

The Reliability of Visual Ratings of Velopharyngeal Physiology for Speech
The Cleft Palate Craniofacial Journal, 2020Background: Analyze intrarater and interrater reliability for evaluating endoscopic images of velopharyngeal (VP) physiology. Method: Speakers produced 9 speech stimuli representing 4 stimulus types: sustained phonemes, repetitions of “

Rating the Impact of Visual Impairment
AMA Guides® Newsletter, 2011Abstract The AMA Guides to the Evaluation of Permanent Impairment (AMA Guides) used the Snell Visual Efficiency Scale (1925). Following scientific progress, the Vision chapter in the fifth and sixth editions of the AMA Guides began using the Functional Vision Score (FVS) that is endorsed by the International Council of Ophthalmology and the ...

Visual communication at very low data rates
Proceedings of the IEEE, 1985A study is reported of the extraction of two-level cartoons from moving grey-level images for visual communication in the range 4.8-19.2 kbits/s. It is postulated that perceptually significant features of the human face and hands, at which cartoon lines should be drawn in the image, occur wherever surfaces in object space are approximately tangential ...
