Charlie is out in his yard playing baseball

I got you my dude.

Improper functioning of the visual system:

Misshapen eyeballs causing nearsightedness/farsightedness

o Misshapen lens causing astigmatism

o Damage/disease to any part of the eye (cornea, lens, retina) or visual cortex (occipital lobe)

o Having the ball fall within Charlie’s blindspot

o Being colorblind (and the team using a colored ball)

Discuss how Charlie could not see the ball properly due to improper

functioning of his visual system, which leads to his being hit by the ball

Binocular depth cues:

o perhaps he had only one functioning eye

o something got in one of his eyes as the ball was coming toward him

o he was focusing on the wrong objects and misjudged the distance

discuss either convergence issues or retinal  disparity

Attention:

o signal detection (the ball wasn’t a big enough signal for him due to distraction/lack of  attention)

0r

o selective attention (he was paying attention to something else and didn’t hear the sounds  of the ball coming toward him)

Discuss Charlie’s lack of attention being the reason the ball hit him

Gate-control theory of pain

Discuss how pain signals are carried on free nerve endings/smaller nerve fibers  and therefore can be gated off in the spinal cord by signals carried on larger nerve fibers that are  directly connected to the sensory receptors. Charlie could ease his pain in his knee somewhat by  stimulating these larger nerve endings (i.e., through pressure to another part of the leg).

Sensory Adaptation:

Discuss that, with time, the pain sensations will not be as noticeable due to  sensory adaptation. Charlie’s brain will begin to focus on other, more novel sensations as time  passes. However, students may also point out that he will again feel the pain when he is  reminded of it or when it changes somehow (i.e, when he moves his leg, etc.).

Explanation:

(Change the wording obviously) Also, please brainliest if you can :)
