A recent ball-catching experiment conducted in space by astronauts on board a space shuttle has led neuroscientists to conclude that the brain contains an internal model of gravity that is both powerful and persistent. At the same time, the experiment provided evidence that the brain can adapt to environments in which the force of downward acceleration is less pronounced than it is on earth.
The experiment’s outcomes suggested that an individual’s understanding of motion is hard-wired from an earthcentric perspective. In the experiment, the astronauts were asked to catch balls released from a spring-loaded cannon.
Analyzing data gathered from infrared tracking cameras and electrodes placed on the astronauts’ arms, McIntyre, the experiment’s principal designer, noticed that the astronauts’ anticipation of the ball’s motion was slightly off. Though they were able to catch the ball, the astronauts expected the ball to move faster than it did. He theorized that this over-anticipation is due to the fact that the brain expects the force of the earth’s gravity to act on the ball.
The experiment also demonstrates the brain’s ability to adjust to conditions that run counter to its pre-set wiring.
While the astronauts did not adapt to the conditions in space for some time, by day 15 of the experiment, the amplitude of the premature arm movements decreased and a new well-timed arm movement immediately preceded the catch. Upon returning to earth, the astronauts again mis-anticipated the ball’s motion, though this time the ball moved faster than anticipated. However, the astronauts were able to adjust back to the earth’s gravitational effect on the balls much more quickly than they had been able to adapt to the conditions in space.
Many scientists view the findings as a first step in research that could have serious practical benefits. The ability of astronauts to safely explore space and investigate other planets is dependent on understanding the differences between our physical reactions on earth and elsewhere.
On another level, understanding timing processes in the body might lead to the development of treatments for coordination problems experienced by individuals with certain types of brain damage.

A recent ball-catching experiment conducted in space by astronauts on ...
The question asks for some information that would support the theory that the brain has built-in knowledge of gravity. The correct answer choice must demonstrate that gravity is not a principle that individuals learn about exclusively through observation and experience, but instead that they are born with some instinctual understanding of downward acceleration.
(A) An individual's hand-eye coordination generally requires some understanding of gravity. For example, one's ability to see a thrown ball and then catch it is, at least in some measure, dependent on the individual's understanding that gravity will be pulling the ball downward. However, the fact that this coordination tends to diminish as one gets older suggests nothing as to whether the brain has built-in knowledge of gravity.
(B) CORRECT. The fact that infants placed above the ground fear falling without ever having experienced it before strongly suggests that their brains are hard-wired with some knowledge of gravity. If the infants did not understand the tendency of objects, including themselves, to accelerate down toward the earth, they would have no reason to become fearful when placed on a glass tabletop.
(C) The disorientation that astronauts experience after departing earth for space may in some way be impacted by the difference between gravitational conditions on earth and in space. However, this has no bearing on whether the brain has built-in knowledge of gravity or not.
(D) The fact that most young children can learn to catch a ball suggests only that they can learn to anticipate the effect of gravitational forces on a ball. It suggests nothing about whether these children understand these forces a priori.
(E) The fact that this is counter-intuitive to most individuals, far from supporting the notion that the brain has built-in knowledge of gravity, actually suggests that people don't fully understand how gravity truly works

In the experiment, the astronauts were asked to catch balls released from a spring-loaded cannon.Analyzing data gathered from infrared tracking cameras and electrodes placed on the astronauts’ arms, McIntyre, the experiment’s principal designer, noticed that the astronauts’ anticipation of the ball’s motion was slightly off. Though they were able to catch the ball, the astronauts expected the ball to move faster than it did. He theorized that this over-anticipation is due to the fact that the brain expects the force of the earth’s gravity to act on the ball.The experiment also demonstrates the brain’s ability to adjust to conditions that run counter to its pre-set wiring.While the astronauts did not adapt to the conditions in space for some time, by day 15 of the experiment, the amplitude of the premature arm movements decreased and a new well-timed arm movement immediately preceded the catch. Upon returning to earth, the astronauts again mis-anticipated the ball’s motion, though this time the ball moved faster than anticipated. However, the astronauts were able to adjust back to the earth’s gravitational effect on the balls much more quickly than they had been able to adapt to the conditions in space.Many scientists view the findings as a first step in research that could have serious practical benefits. The ability of astronauts to safely explore space and investigate other planets is dependent on understanding the differences between our physical reactions on earth and elsewhere.On another level, understanding timing processes in the body might lead to the development of treatments for coordination problems experienced by individuals with certain types of brain damage.Q.Which of the foll owing, if tr ue, would s upport McIntyre’s theory that the brain has built-in knowledge of gravity?a)An individua l’s hand-eye coordinat ion tends to diminish with age.b)Infants become fearful when placed on a glass tabletop where they can see the floor, even though they have never had the experience of falling.c)Astronauts initially feel disoriented during the first several days after departing earth for space.d)Most children can learn to catch a ball at a very young age.e)It is counter-intuitive to most individuals that if no air resistance were present, a bowling ball and a feather dropped at the same time from the same height will reach the ground at the same time.Correct answer is option 'B'.
