KM’s Hypothesis: Why do we do Typo-errors?

KM’s Hypothesis: Why do we do Typo-errors?

 

One of the most common things we do encounter when we type is the Typo-error, which we tend to commit when we text our friends.

cf870399694ec4e146d8a74022244b49What happens basically in Typo-errors?

Fingers do target one place and reach a place adjacent to it

Here we have a combined set of 3 hypothesis and 1 statement, which in union, makes us to commit Typo-errors!

(If you are too busy to read, just scroll for the answers in the end)

********

 

Hypothesis #1

Do we really see the keyboard when we text?

Nope! When we don’t see the keyboard and type our texts (by seeing the monitor board), we are not giving proper visual inputs to our cerebellum!

 

Remember that: When we initially learn the act of Typing, we teach cerebellum to see the Board and type! That’s for what the pathways initially develop

Later, we leave the habit of seeing the board which may also cause changes in the already developed pathways and may put cerebellum under trouble!

 

Since our cerebellum is the major pathway which is involved in controlling fine directional movements of our hand, it is definitely the unsung hero behind typing, as well as the Villian behind our Typo-errors!

 

Statement #2

The Speed of Texting your bf/gf

One major determinant is the speed which we use for Typing, but since it is a known fact..I am not keeping it as a hypothesis but as a statement. Here too, our cerebellum plays that key role to perform!

 

Hypothesis #3: Considering every component of Speech Pathway

brocas-etc

Every motor act has two inputs from:

(1) Cerebellum-which determines the rate, force and direction of the movement

(2) Basal Ganglia-which involves regulation of fine coordinated movements

If these 2 functions do not happen, it could have reflected in every fine motor act of ours,not just typing alone!

So, the main problem is not with these two!

********

Let’s consider the Phonological Loop (the loop which is responsible for understanding and expressing speech)

 

We see our friend’s text (the visual input goes to primary visual cortex where it is perceived and then goes to secondary visual cortex for processing)

—>

Our phonological loop can take only Auditory input to process further

So, this processing of visual input will not be possible until it is converted into an auditory speech called Internal speech (this is done by Dejerine area)

—>

This Internal speech, now, can be sent to Wernicke’s area where our speech input is understood (Remember, we all have no problem in understanding things. So the problem is not here of course)

—> via arcuate fasciculus –>

The input goes to Broca’s area (here only what we express as speech is created)

No surprise that this area is in Frontal Lobe!

—>

The Input, then goes to *Exner’s Area* where this output speech which is created by Broca’a area is recreated into words and messages (i.e) Exner’s area commands hand muscles to type or write what we thought!

So, Is that Exner’s Area our main culprit?

Yes, to be told straight! Since, this area is most likely to be involved in texting our girlfriend!

Due times of stress or depression or just over-thinking, the area where the Exner’a area is located (Frontal Lobe) works a lot! Fires a lot! By the stand of hypothesis, this over-firing causes exhaustion of required number of vesicles in the adjacent areas and pathways like Exner’s

This hypothesis could neatly explain why we commit typo-errors especially when we are not fully alert !

CONCLUSION: “Involvement of Exner’s area creates Typo-errors, when our frontal lobe undergo over-thinking”

 

Hypothesis #4-Phylogenetic Hypothesis

evolution_of_man

By the concepts of evolution, for this particular act of Typing, there is no already coded pathway (in birth) to perform!

Our typing skills are something which purely depend on those pathways which are developed by Learning mechanisms

So, these newly developed pathways are most likely to be less stronger compared to pathways related to writing. This could explain why writing is not a problem compared to Typing

CONCLUSION: “The Less-genetically coded pathways for Typing makes us to create typo-errors”

THE BLOG ANSWER

What makes us to make Typo-errors?

(1) Our Cerebellum is lacking necessary inputs from our visual area, for typing

(2) Our Cerebellum faces too many firings at a time, when we type faster

(3) Exner’s area shows weakened firing when we over-think at times of Stress and Depression

(4) Evolutionary absence of genes to code for Typing pathways doesn’t make it an innate ability
