If Gloves Could Talk

Over 40 million people use sign language instead of speech due to hearing and speech impairments. Imagine if these people could communicate with non-signers using magic talking gloves…

Enable Talk is aiming to achieve just this. Sensor covered gloves send signals to a smart phone and hey presto, your hands are talking! The student project is still a work in progress for the Ukrainian team behind it, QuadSquad, who have tested various prototypes on sign language users in the Ukraine.

Enable Talk gloves translate sign language into speech using only a smart phone app.

Aphasia – When Language Goes Wrong

a·pha·sia ˈfāZHə/

Noun:
Loss of ability to understand or express speech, caused by brain damage.

I thought I’d explain in this post why it is that I’m fascinated with the phenomenon that is aphasia. The main reason it’s so interesting is that it can manifest itself in very different ways. Aphasia is a result of brain injury, most commonly strokes, head trauma or neurodegenerative diseases like dementia and Parkinson’s. So the effects observed in language depend on which part of the brain’s language areas were damaged; yet, not even this is necessarily consistent or predictable. Some of the stranger and more surprising effects can be seen in bilingual patients who can regain the use of one language but not the other, inadvertently switch language or communicate using a mixture of the two languages.

Recovery Patterns in Bilingual Aphasia: Influential Factors & Cross-Language Transfer

Over 2/3 of the world’s population speak more than one language, generating interest in the field of bilingual aphasia and particularly its recovery. Among the many theories on recovery patterns, it is widely accepted that parallel recovery of a bilingual’s languages is the most common (i.e. both languages recover at the same rate). Of those cases of nonparallel recovery, the oldest theories on which language recovers best are the first language (Ribot’s law) or the dominantly used language (Pitres’ law). This review discusses the evidence for these theories in addition to considering influential factors of recovery, and exploring whether therapy in one language can transfer to untreated languages.
