Psychology 101 Final Exam
1. The site of chemical communication in the brain is the ________.
- A. neuron
- B. synapse
- C. axon
- D. dendrite
Correct answer: B
Rationale: The synapse is the correct answer. It is the site where communication between neurons occurs through the release and reception of neurotransmitters. Choice A, neuron, is incorrect as it is the cell itself rather than a specific site of communication. Choice C, axon, is also incorrect as it is a part of the neuron that transmits signals away from the cell body. Choice D, dendrite, is not the correct answer either, as dendrites receive signals from other neurons but do not release neurotransmitters for communication.
2. In order for one to be diagnosed with panic disorder, the panic attacks must?
- A. Suddenly; unexpectedly
- B. Suddenly; gradually
- C. Gradually; unexpectedly
- D. Unexpectedly; suddenly
Correct answer: A
Rationale: The correct answer is A: 'Suddenly; unexpectedly.' Panic disorder is diagnosed when panic attacks occur unexpectedly, not gradually. Panic attacks are characterized by their sudden onset and are unpredictable. Choice B is incorrect because panic attacks do not manifest gradually. Choice C is incorrect because panic attacks are not expected or predicted. Choice D is incorrect as well because the unexpected nature of panic attacks is a key criterion for diagnosing panic disorder.
3. Which of the following is an example of telegraphic speech?
- A. A child pointed to his father's shoe and said 'daddy,' as if to convey 'daddy's shoe.'
- B. A thirsty toddler said, 'mama water.'
- C. A newborn infant asked, 'Can I have some coffee?'
- D. A baby communicated to her parents using her brain.
Correct answer: B
Rationale: The correct answer is B. Telegraphic speech is when a child uses a two-word phrase to convey a larger meaning, such as 'mama water.' Choice A is incorrect as it does not demonstrate telegraphic speech but rather a simple labeling. Choice C is incorrect as it is a complete sentence and not a two-word phrase. Choice D is also incorrect as it does not describe telegraphic speech but rather a vague statement about communication.
4. How does the concept of neural plasticity relate to recovery from brain injuries?
- A. Neural plasticity means the brain cannot recover from injuries.
- B. Neural plasticity allows the brain to recover and reorganize after injuries.
- C. Neural plasticity refers to the brain's inability to change after injury.
- D. Neural plasticity is a myth.
Correct answer: B
Rationale: Neural plasticity allows the brain to recover and reorganize after injuries. It is the brain's ability to adapt and change, forming new connections or reorganizing existing ones to compensate for damage. Choice A is incorrect as neural plasticity enables recovery. Choice C is incorrect as neural plasticity involves the brain's capacity to change. Choice D is incorrect as neural plasticity is a well-established phenomenon in neuroscience.
5. Where is the site of chemical communication in the brain?
- A. Neuron
- B. Synapse
- C. Axon
- D. Dendrite
Correct answer: B
Rationale: The correct answer is B: Synapse. The synapse is the site where chemical communication occurs between neurons. Neurotransmitters are released from the axon terminal of one neuron, cross the synaptic cleft, and bind to receptors on the dendrites of the next neuron. Choice A, Neuron, is incorrect as it refers to the entire nerve cell. Choices C and D, Axon and Dendrite, are also incorrect as they are specific parts of a neuron and not the primary site of chemical communication.
