Psychology 101 Final Exam

1. 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.

2. What role does culture play in understanding abnormal behavior?

A. Culture plays a minimal role in understanding abnormal behavior.
B. Culture is essential in shaping our perceptions and definitions of abnormal behavior.
C. Culture has little impact on the expression of abnormal behavior.
D. Culture only affects the treatment of abnormal behavior, not its understanding.

Correct answer: B

Rationale: Culture is essential in shaping our perceptions and definitions of abnormal behavior. Choice A is incorrect because culture actually plays a significant role in understanding abnormal behavior. Choice C is incorrect as culture can have a considerable impact on how abnormal behavior is expressed. Choice D is incorrect because culture influences not only the treatment but also the understanding of abnormal behavior.

3. What is the biopsychosocial model?

A. A model that integrates biological, psychological, and social factors in understanding mental disorders.
B. A model that emphasizes the interaction between biological and psychological factors, excluding social influences.
C. The biopsychosocial model emphasizes only psychological factors in mental disorders.
D. The biopsychosocial model is a purely biological approach to mental health.

Correct answer: A

Rationale: The biopsychosocial model is a comprehensive approach that considers biological, psychological, and social factors in understanding mental disorders. Choice A is correct because it accurately describes how this model integrates these three factors. Choice B is incorrect as it excludes social influences from the model. Choice C is incorrect because it states that the model only emphasizes psychological factors, which is not true. Choice D is incorrect as it suggests that the model is purely biological, which is also inaccurate.

4. What are psychology's intellectual parents?

A. Physics and physiology.
B. Philosophy and physiology.
C. Chemistry and physics.
D. Philosophy and chemistry.

Correct answer: B

Rationale: Psychology's intellectual parents are philosophy and physiology. Philosophy contributed to the early development of psychology by exploring questions about the mind and behavior, while physiology provided a scientific foundation for understanding the biological aspects of human psychology. Choices A, C, and D are incorrect as they do not accurately represent the disciplines that significantly influenced the emergence of psychology as a distinct field of study.

5. What is the result when a single zygote separates into two parts, each developing into a separate individual?

A. Dizygotic twin
B. Monozygotic twin
C. Fraternal twin
D. Nonidentical twin

Correct answer: B

Rationale: The correct answer is B, Monozygotic twin. A monozygotic twin, also known as an identical twin, is the result when a single zygote splits into two parts, leading to the development of two genetically identical individuals. Choices A, C, and D are incorrect because they do not accurately describe the scenario where a single zygote splits into two parts to form identical twins. Dizygotic twin (Choice A) refers to fraternal twins, which result from two separate eggs fertilized by two different sperm cells. Fraternal twin (Choice C) is another term for dizygotic twins, arising from two separate zygotes. Nonidentical twin (Choice D) is a synonymous term for dizygotic or fraternal twins, indicating that they are not genetically identical.
