Amblyopes and nonamblyopes were compared on 2 tests of spatial perception. One, the Titmus stereotest, provided only disparity cues and thus measured pure stereopsis. The other, the 3-rods test, provided a variety of monocular and binocular cues and measured the precision of distance discrimination. On both tests the amblyopes were significantly worse than nonamblyopes with equivalent acuity de...

In task-environments with limited visibility (e.g. rescue workers in smoke), individuals rely on tactile perception as a primary mode of data acquisition. They need to translate tactile information into three-dimensional images, to solve problems mentally, before translating them into motor actions. To assess this ability in an inexpensive, standardised way, the Tupperware Neuropsychological Ta...

We describe a technique to generate critical hazard-free tests for self-timed control circuits build using a macromodule library, in a partial scan based DFT environment. We propose a 6 valued algebra to generate these tests which are guaranteed to be critical hazard free under an unbounded delay model. This algebra has been incorporated in a D-algorithm based automatic test pattern generato,:

Hazard perception is considered one of the most important abilities in road safety. Several efforts have been devoted to investigating how it improves with experience and can be trained. Recently, research has focused on the implicit aspects of hazard detection, reaction, and anticipation. In the present study, we attempted to understand how the ability to anticipate hazards develops during tra...

PURPOSE To clarify the relationship between psychoacoustic capabilities and speech perception in adolescents with severe-to-profound hearing loss (SPHL). METHOD Twenty-four adolescents with SPHL and young adults with normal hearing were assessed with psychoacoustic and speech perception tests. The psychoacoustic tests included gap detection (GD), difference limen for frequency, and psychoacou...

Imperfect repair models are a class of stochastic models that deal with recurrent phenomena. This article focuses on the Block, Borges, and Savits (1985) age-dependent minimal repair model (the BBS model) in which a system that fails at time t undergoes one of two types of repair: with probability p(t), a perfect repair is performed, or with probability 1-p(t), a minimal repair is performed. Th...

Maximum short segments of quantity in 120 discrimination tests at the word level were compared between twoand three-choice alternatives and with production test results utilising the same syllable structures. The materials in the perception test were eight kinds of bisyllabic synthetic nonsense words with five different prosodic patterns. These structures were used in the production test. 28 Fi...
