Project DyAdd: Non-linguistic Theories of Dyslexia Predict Intelligence

Eye movement patterns in linguistic and non-linguistic tasks in developmental surface dyslexia.

Ten subjects who could be reliably assessed as surface dyslexics were selected on the basis of a large test battery. Eye movements in non-linguistic and linguistic tasks were studied in these subjects. Stability of fixation on a stationary stimulus was examined. Performance of dyslexics was no different from that of an age-matched control group. Similarly, no difference was observed between the...

Theories of Intelligence

o be labeled as being ‘‘intelligent’’ imparts positive feelings, encourages self esteem and a sense of worth. Yet, what is intelligent and smart? This has been the focus of theories, definitions and philosophies dating as far back as Plato (428 BC); yet most presumably, dating prior to this historical figure, might be due to the fact that humankind is himself intelligent. One way to seek unders...

Bilingualism: Cross-linguistic Issues in Dyslexia

Research suggests that more cases of dyslexia are diagnosed in populations that speak languages with highly opaque writing systems, such as the United States, the United Kingdom, or France, and fewer cases of dyslexia are diagnosed in populations that speak language with transparent writing systems, such as Italy, Spain, or Mexico. This disparity can be explained by the differences in how dysle...

On measuring linguistic intelligence

This work addresses the problem of measuring how many languages a person “effectively” speaks given that some of the languages are close to each other. In other words, to assign a meaningful number to her language portfolio. Intuition says that someone who speaks fluently Spanish and Portuguese is linguistically less proficient compared to someone who speaks fluently Spanish and Chinese since i...
