LIVE QUIZIZZ GAME

Which scenario best illustrates a conditioned response?

• A plant growing toward light

• A dog salivating when food is placed in its mouth

• A dog salivating when it hears a bell after training

• A child pulling away from a hot object

A person touches a hot stove and immediately pulls their hand away. What part of the nervous system is primarily responsible for this response?

• Brain only

• Peripheral nervous system only

• Reflex arc involving spinal cord

• Sympathetic nervous system

A student studies in a noisy environment but remains focused. This demonstrates the role of:

• Hypothalamus in suppressing emotions

• Selective attention as a cognitive filter

• Unconditioned stimulus blocking

• Reflex inhibition

When you smell your favorite food and start to feel hungry, which type of stimulus is involved?

• Visual stimulus

• Internal stimulus

• Olfactory stimulus triggering conditioned response

• Auditory stimulus

If a stimulus is repeated but the response gradually diminishes, what process is occurring?

• Habituation

• Sensitization

• Conditioning

• Feedback inhibition

Which of the following best compares innate and learned responses?

• Both are controlled by the spinal cord

• Innate responses require repeated exposure to stimuli

• Learned responses involve memory and experience; innate do not

• Both can be consciously controlled

If a person with a damaged occipital lobe cannot respond to visual stimuli, this indicates:

• Sensory input is failing at the receptor level

• The motor neurons are unresponsive

• The brain cannot process visual stimuli

• The cerebellum is damaged

In plants, the hormone auxin controls growth toward light. What kind of response is this?

• Taxis

• Reflex

• Tropism

• Feedback loop

Which component is missing if a stimulus does not lead to a response in the nervous system?

• Stimulus receptor

• Spinal cord

• Hormone secretion

• External effector

Why would a reflex action not involve the brain immediately?

• The brain is too slow

• Reflexes are learned

• Reflexes are automatic and managed by the spinal cord

• The brain only processes visual responses
