1. Roger has suffered a major brain injury. As a result, he is unable to speak fluently, tends to mispronounce words, and speaks haltingly. For instance, he says 'wat' instead of 'watch' and 'tot' instead of 'talk.' What is the diagnosis?

• A. Agnosia
• B. Spatial neglect
• C. Broca's aphasia
• D. Prosopagnosia

Correct answer: C

Rationale: The correct diagnosis for Roger's condition is Broca's aphasia. Broca's aphasia is characterized by difficulty in speaking fluently and accurately, often due to brain injury. In this case, Roger's symptoms of being unable to speak fluently, mispronouncing words, and speaking haltingly align with the characteristics of Broca's aphasia. Agnosia refers to the inability to recognize or interpret sensory information, spatial neglect is the lack of awareness of one side of the body or space, and prosopagnosia is the inability to recognize faces, none of which match Roger's symptoms.

2. 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.

3. The process of ________ is used to increase the probability that a behavior will occur.

• A. operant conditioning
• B. reinforcement
• C. classical conditioning
• D. punishment

Correct answer: B

Rationale: The correct answer is reinforcement. Reinforcement involves providing a consequence that increases the likelihood of a behavior being repeated. Operant conditioning (Choice A) refers to learning through consequences for behavior, which includes reinforcement and punishment. Classical conditioning (Choice C) involves forming associations between stimuli and involuntary responses. Punishment (Choice D) involves providing a consequence that decreases the likelihood of a behavior being repeated. In this context, the question specifically asks about a process that increases the probability of a behavior occurring, aligning with the concept of reinforcement.

4. How does stress impact brain function?

• A. Stress has no effect on brain function.
• B. Stress can lead to changes in brain structure and function.
• C. Stress can improve brain function.
• D. Stress has no long-term impact on brain function.

Correct answer: B

Rationale: Stress can lead to changes in brain structure and function, affecting mental health and increasing the risk of disorders. Choice A is incorrect as stress does affect brain function. Choice C is incorrect as stress generally has negative impacts on brain function rather than improving it. Choice D is incorrect because stress can have long-term impacts on brain function through structural and functional changes.

5. Unlike those with autism spectrum disorder, those with reactive attachment disorder have a history of:

• A. Schizoid personality disorder
• B. Autism spectrum disorder
• C. Reactive attachment disorder
• D. Disinhibited social engagement disorder

Correct answer: C

Rationale: The correct answer is C: Reactive attachment disorder. Individuals with reactive attachment disorder have a history of severe social neglect, which distinguishes it from autism spectrum disorder. Choice A, Schizoid personality disorder, is incorrect as it is not typically associated with the history described in reactive attachment disorder. Choice B, Autism spectrum disorder, is incorrect because individuals with autism spectrum disorder do not necessarily have a history of severe social neglect. Choice D, Disinhibited social engagement disorder, is also incorrect as it is a separate attachment disorder characterized by indiscriminate social behavior, not necessarily a history of neglect.
