Opening Eyes to Learning Difficulties

Learning difficulty and disability has long been a problem for many children, parents and school teachers alike. Dysfunctions such as dyslexia and motor disability have hindered the progress of countless adolescents across the country and continue to do so with every passing day. Now, studies have been performed that may centralize learning difficulties to the eye, rather than the brain itself.

Researchers at the Norwegian University of Science and Technology are conducting research that creates a causal link between motor and learning disabilities and dysfunction in visual perception. For example, people who cannot quickly learn a simple motor task such as catching a ball may have difficulty because the cells in their eyes are not perceiving the stimulus properly. The same rings true in individuals with dyslexia – their eyes may not be correctly processing the visual stimuli of words on the page.

Learning disability has long puzzled scientists and sufferers alike.

Learning disability has long puzzled victims, observers and scientists.

The ocular cells in contest here are deemed “magno cells” and detect rapid movements in our visual field, creating the movie-like perception we experience on a daily basis. Without these, life would look like a disconnected string of frames – much like a comic book. In a test conducted by the researchers, it was found that individuals with difficulty in mathematics also showed difficulty in tracking the randomized movement of a dot on a screen with their eyes, elucidating a link between eye function efficiency, detection of rapid changes in the environment and learning ability.

In a greater context, this finding may have implications in special education and may change the mindset of those working with individuals with additional learning needs. With this new information, learning disability can be combated from the angle of visual field perception. Techniques aiming to strengthen visual perception and eye efficiency (such as eye movement and tracking exercises) could act as a therapy for learning or motor disability previously thought to be localized in the brain itself.

Toasters With Feelings

Anthropomorphism is the attribution of human characteristics to inanimate objects, animals, or God. It has been a hallmark of faiths and religions worldwide. Humans have a natural tendency to assign intentions and desires to inanimate objects (“my computer isn’t feeling well today – he’s so slow!”), but they also strip “lower” beings (animals) of those same human characteristics.

We have a history of treating animals unnecessarily cruelly. I don’t mean killing for food – that’s necessary for our survival; I’m referring to dog fights, hunting, and other violence. We didn’t even think that animals could sense pain until quite recently!

Why do we think of lifeless forms as agents with intentions but of actual living creatures as emotionally inferior clumps of cells?

Could it be that the need to rationalize phenomena is simply stronger when the phenomena have absolutely no visible explanation?

And do toasters really have feelings??
