Psychology Perception - While playing outside with his friends, A-Rod gets hit in the knee with a ball. Improper functioning of the visual system is the first thing that affected his perception

Extracts from this document...

Introduction

´╗┐While playing outside with his friends, A-Rod gets hit in the knee with a ball. Improper functioning of the visual system is the first thing that affected his perception. Objects that are closer to us produce bigger images on our retinas. The size of the ball was kept constant in A-Rod?s mind, even though the picture on his retina changed in size. Shape constancy states that objects viewed from different angles will produce different shapes on our retinas, but we know that the shape of the object remains constant; this is the case for A-Rod. The final contributor to how vision affected his perception would be that we perceive objects as being a constant color even as the light reflecting off the object changes. ...read more.

Middle

The more of a difference the images are between the eyes, you brain will assume the object is closer. In this case, A-Rod?s eyes could have perceived the ball to be farther away than it truly was, resulting in it hitting his knee. As an object comes closer to us, our eye muscles must strain to stay focused on the object. The brain receives feedback from the muscles controlling eye movements and knows that the more the eye converges, the closer the object must be, and this is convergence. The Gate Control Theory states that incoming pain must pass through a gate which is located in in the spinal cord which determines what information about pain will be sent to the brain. ...read more.

Conclusion

Our bodies try to think, feel, see, hear all the objects that incoming out from our environment. When our minds are fully focused in the subject, we grasp without hesitation and then speed and accuracy respond. A-Rod?s reactions were either slowed, or his sensory system was not fully awake at the time of the injury. The final component that would have affected A-Rod?s perception of this experience would be selective attention. Selective attention is the process of discriminating between what is important and is irrelevant and is influenced by motivation. In the case of A-Rod, his friends were devoting their full attention to passing the ball to A-Rod, however, A-Rod was paying attention to more specific things such as who was throwing it and not the same things that his friends were paying attention to. ...read more.
