AceReader® VT Software It can be used to: (1) Assess your current reading level (2) Improve your reading speed and comprehension, both online and offline (3) Help you read faster while on the computer, by utilizing special display modes. AceReader® helps you break two major bad habits: (1) Subvocalization (pronouncing the words in your mind while you read), and (2) Re-Reading/Regression (letting your eyes wander back to re-read text). AceReader® paces you to read at higher speeds. At these higher speeds, it becomes physically impossible to subvocalize. And because AceReader® displays text by flashing word sets, you will be forced to read ahead and will not have the opportunity to regress. AceReader® will also help you: (1) Reduce Your Eye Fixation Time (time spent when your eyes are focused on a single point), (2) Expand Your Eye Fixation Zone (ability to read a wider text width when your eyes are focused on a single point) and (3) Increase Your Re-Fixation Speed (ability to reposition your eyes at a rapid rate). -

Farnsworth D15 Dichotomous Color Test Farnsworth Test for Congenital and Acquired color defects. The Farnsworth D-15 contains a reference disc holding notation 10 B 5 4 and fifteen numbered discs which make up an incomplete color circle. The patient arranges the discs and then evaluation of the patients arrangement separates 'normal' color perception from moderate and strong defects in deutan, protan or tritan axis color discrimination. The D-15 is housed in a plexiglass container. the disks are spread out on a table and arranged by the patient. The Farnsworth D-15 test is a subset of the well known Farnsworth 100 Hue Test. It is intended for classification instead of in-depth study of color vision defects. The D-15 and 100 hue tests are correlated. Growing Importance of Color deficiency Screening. In addition to congenital color deficiency screening there is growing evidence that adult acquired color deficiency, especially in yellow and blue perception, can indicate medical toxicity and other problems. Increasingly complex security and medical systems also require verification of all three types of color receptors. How the D-15 test works: The Farnsworth D15 is called 'dichotomous' because it is designed to separate subjects into one of two groups, 1) Strongly color deficient or 2) Mildly color deficient or color normal. This is accomplished by the arrangement of vivid (saturated) colored discs. A perfect score shows normal color perception. A non-perfect score is used to determine a medium or strong color deficiency.
