Exam 4 Psychology 101

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.

Correct Answer: A

Rationale: The correct answer is A: Structuralism. Structuralism involves introspection, where individuals report their thoughts and feelings while engaging with stimuli. In this scenario, Isabel is recording her feelings and impressions while listening to music, which aligns with the introspective nature of structuralism. Choices B, C, and D are incorrect because functionalism focuses on the purpose of behaviors, behaviorism emphasizes observable behaviors and environmental influences, and humanism highlights individual growth and personal experiences rather than introspection.

Correct Answer: D

Rationale: John Watson was a key figure in the development of behaviorism, which advocated for focusing on observable behavior rather than the study of consciousness. Choice D is the correct answer because Watson believed that psychology should abandon the study of consciousness. Choices A, B, and C are incorrect because Watson's approach emphasized behavior and rejected the importance of consciousness, introspection, or confining psychology to only mentally ill individuals.

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.

Correct Answer: B

Rationale: In a breech presentation, the infant is positioned to be delivered feet or bottom first. This is because the baby's pelvis or feet enter the birth canal before the head. Therefore, choice B is correct. Choices A, C, and D are incorrect because a breech presentation specifically refers to the baby being positioned feet or bottom first, not head first, face down, or being too large for vaginal delivery.
