Conditioned place preference
b)

Olds and Milner’s rats and Skinner’s pigeons learned to voluntarily execute an unnatural behavior to receive a reward (i.e. electrical stimulation of the mesolimbic pathway and a sweet food treat, respectively). Why are these experimental procedures considered to reflect operant rather than classical conditioning?
a)
The behaviors are learned and voluntarily expressed to obtain a reward
b)
The behaviors are unnatural
c)
The animals learn to associate environmental cues with the behaviors and with a reward
d)
All of the answers provided are correct
Why would you expect a recovering alcoholic to crave alcohol when they walk into a bar?
a)
Neuroplasticity within the mesocorticolimbic circuit has consolidated alcohol-associated memories, which are triggered in response to alcohol-associated cues in the bar
b)
Environmental cues associated with previous alcohol-intoxicating experiences trigger craving
c)
Both environmental cues and neuroplasticity
d)
None of the answers provided are correct
Why may it be more difficult to extinguish a conditioned response utilizing the self-administration (SA) animal of drug abuse, as compared to the conditioned place preference (CPP) animal model?
a) Conditioned aversion cannot be distinguished, regardless the number of conditioning trials
b) Conditioned rewards cannot be extinguished, regardless the number of conditioning trials
c) It is actually more difficult to extinguish a CPP response, as compared to conditioned SA behaviors
d) It may be more difficult to extinguish all drug-associated discrete cues in the SA experiment, as compared to the general drug-associated cues in the CPP experiment
Development…
a)

c)
All of the answers provided are correct
d)

Which of the following accurately describes the developing organism and its course, during prenatal development?

b)
Embryo (embryonic period) –> fetus (fetal period) –> zygote (germinal period)
c)
Zygote (germinal period) –> embryo (embryonic period) –> fetus (fetal period)
d)
Fetus (fetal period) –> zygote (germinal period) —> Embryo (embryonic period)
