Question

which of the following statements is true of unconditioned stimuli?
multiple choice
they cause neurotransmitters to be absorbed by ganglia
they are previously neural stimuli that eventually elicit a conditioned response
they are neural stimuli that cause synesthesia
they produce a response without prior learning

Explanation:

An unconditioned stimulus is a core concept in classical conditioning; it inherently triggers a natural, automatic response in an organism with no prior learning required. The other options are incorrect: unconditioned stimuli are not defined by neurotransmitter absorption by ganglia, they are not stimuli that develop conditioned responses (that describes neutral/conditioned stimuli), and they do not relate to synesthesia.

Answer:

They produce a response without prior learning
