Example Question #1 : Physiology Of Behavior
Which of the following behaviors accurately describes a baby's Babinski reflex?
The baby stepping in response to feeling one of his feet touch a flat surface.
The baby grasping his hand in response to feeling a stroke on his palm.
The baby moving his big toe upward in response to feeling a stroke on the bottom of his foot.
The baby sucking in response to feeling something touch the roof of his mouth.
The baby moving his big toe upward in response to feeling a stroke on the bottom of his foot.
The Babinski reflex occurs when a baby moves his or her big toe upward in response to feeling a stroke on the bottom of his or her foot. The other three reflexes described in the answer choices all have different names. When something touches the roof of a baby's mouth, the baby will suck, which is referred to as the sucking reflex. The walking/stepping reflex is when a baby makes a stepping motion after feeling one of his feet touch a flat surface. Finally, the palmar grasp reflex is when a baby grasps his hand in response to feeling a stroke on his palm.
Example Question #2 : Physiology Of Behavior
From most basic to most complex, what is the correct order of movement types that occur during human development?
Reflexive, rudimentary, fundamental, specialized, lifelong application
Reflexive, fundamental, rudimentary, specialized, lifelong application
Rudimentary, reflexive, fundamental, specialized, lifelong application
Reflexive, rudimentary, specialized, fundamental, lifelong application
Reflexive, rudimentary, fundamental, specialized, lifelong application
The earliest movements humans perform during motor development are known as reflexive movements. These are followed by rudimentary movements, and then fundamental movements. The final stage is known as the lifelong application stage in which movements are continually adjusted and refined for efficiency. Last, the specialized movement stage is sometimes broken up into two stages: the transitional substage and the application substage; however, none of the answer choices mention either of those substages.
