Exam 4 Psychology 101

Correct Answer: D

Rationale: The correct order of the three stages of prenatal development is germinal stage, embryonic stage, and fetal stage. During the germinal stage, the fertilized egg rapidly divides and implants in the uterine wall. The embryonic stage follows, where major organs and systems begin to develop. Finally, during the fetal stage, the developing organism is known as a fetus and continues to grow and mature. Choice A is incorrect because it has the stages in the wrong order. Choice B is incorrect as it also presents the stages out of order. Choice C is incorrect as it reverses the order of the stages. Therefore, the correct answer is D.

Correct Answer: A

Rationale: The correct answer is A: Catatonia. Catatonia is a symptom seen in some cases of schizophrenia, characterized by motor abnormalities such as peculiar hand and limb movements or adopting unusual postures for extended periods. Choice B, Loose association, refers to a thought disorder where ideas shift from one subject to another in an unrelated way. Choice C, Disorganized speech, is characterized by incoherent or incomprehensible speech patterns. Choice D, Blunted affect, describes a reduction in the intensity of emotional expression.

Correct Answer: D

Rationale: The correct answer is D, 'Long-term memory.' In the 5th substage of sensorimotor development, Piaget refers to 'experimentation' as tertiary circular reactions, where the infant tries out new ways of playing with or manipulating objects. This stage involves exploring and testing different ways of interacting with the world to understand cause and effect relationships. Choices A, B, and C are incorrect as they do not align with Piaget's concept of tertiary circular reactions and experimentation in the sensorimotor stage of development.

Correct Answer: C

Rationale: The functionalist perspective, as used by Dr. Lee, focuses on understanding the role of pain in human survival and adaptation. This perspective suggests that to fully comprehend pain perception, one must first grasp the significance of pain in terms of its adaptive functions and impact on behavior. Choices A, B, and D do not align with the functionalist perspective, as they do not emphasize the role of pain in human survival and adaptation.

Correct Answer: B

Rationale: The correct answer is B: Proximodistal pattern. Differences between monozygotic twins raised in the same environment are likely due to non-shared environmental influences, which lead to differences in interests, hobbies, and other individual characteristics. Choices A, C, and D are incorrect. Cephalocaudal pattern refers to the principle of development from head to toe, not relevant in explaining differences between twins. Cephamodistal pattern is not a recognized developmental term. Gene-environment correlation does not directly explain the differences between identical twins raised in the same environment.
