AP psychology- multiple choice
DOC The figure shows the myelin sheath, a semipermeable membrane that provides support and helps speed up the action potential in neurons. What condition occurs when the immune system causes the deterioration of the myelin sheath? Responses A Alzheimer's disease B Multiple sclerosis C Autism D Myasthenia gravis
B Multiple sclerosis
Kara thinks she sees a spider on the floor of her bathroom. She is extremely afraid of spiders. Upon further inspection, though, she realizes the "spider" is only a ball of hair. Which of the following nervous systems would be responsible for calming her down after she realizes the ball of hair is not a spider? Responses A Somatic nervous system B Parasympathetic nervous system C Sympathetic nervous system D Central nervous system
B Parasympathetic nervous system
DOC Which branch of the autonomic nervous system is described by the functions listed in Part B of the table? Responses A Parasympathetic nervous system B Sympathetic nervous system C Central nervous system D Somatic nervous system
A Parasympathetic nervous system
The drugs that block the reabsorption of neurotransmitters in the synapse during neural transmission are best identified as which of the following concepts? Responses A reuptake inhibitors B antipsychotics C antihistamines D stimulants
A reuptake inhibitors
Based on its effects on the central nervous system, alcohol can be classified as which of the following concepts? Responses A a hallucinogen B a depressant C an antagonist D a neurotransmitter
B a depressant
Researchers measured changes in neural firing in the frontal lobes for ten rats that were exposed to stimulants. The researchers used an MRI that indicates brain activity with colors. Normal brain activity is indicated by greens and yellows. High brain activity is indicated by reds and oranges. Low brain activity is indicated by grays and blues. All the rat's brains showed normal activity prior to being exposed to the stimulant. What is the operational definition of neural activity in the rats? Responses A The amount of stimulant given to each rat. B Random selection of the rats from a large population to be part of the stimulant group. C The color presented in the MRI images. D The size of the rats' frontal lobes.
C The color presented in the MRI images.
DOC Which psychological principle is represented in the area highlighted in the graph? Responses A The variable-interval schedule of reinforcement. B The forgetting curve. C The refractory period of the neural transmission process. D Spontaneous recovery of a classically conditioned response
C The refractory period of the neural transmission process.
DOC The graph depicts which of the following? Responses A Long-term potentiation B Brain plasticity C The sleep/wake cycle D The process of neural transmission
D The process of neural transmission
