1. Which of the following is not a common method for studying genetic influences?

• A. The study of specific gene defects
• B. Twin studies
• C. Adoption studies
• D. Family history (pedigree) studies

Correct answer: A

Rationale: The correct answer is A. Studying specific gene defects is not a common method for investigating genetic influences. Choices B, C, and D are common methods used in genetic research. Twin studies help determine the heritability of traits, adoption studies compare similarities between adopted individuals and their adoptive families versus biological families, and family history studies track the inheritance patterns of traits within families.

2. What is the term for a fluid-filled sac in which the baby floats until just before it is born?

• A. Amnion
• B. Placenta
• C. Umbilical cord
• D. Embryo

Correct answer: A

Rationale: The correct answer is A: Amnion. The amnion is a fluid-filled sac that surrounds and protects the developing fetus in the womb. It acts as a cushion, maintaining a stable temperature and protecting the fetus from external pressure. Choices B, C, and D are incorrect because the placenta is an organ that provides nutrients and oxygen to the fetus and removes waste products, the umbilical cord connects the fetus to the placenta to facilitate nutrient exchange, and an embryo is an early stage of development before it becomes a fetus.

3. To overcome her fear of balloons due to the loud sound they might make when popping, Bella must sit in a room filled with balloons while the therapist pops each one. After a while, Bella realizes that her fear is unjustified and even begins to pop balloons herself. This technique is known as?

• A. Systematic desensitization
• B. Aversion therapy
• C. Flooding
• D. Extinction

Correct answer: C

Rationale: The correct answer is C, Flooding. Flooding is an exposure therapy technique where a person is exposed to their fear at full intensity until the fear subsides. In this scenario, Bella is exposed to her fear of balloons in a controlled environment until she realizes her fear is unjustified. Choice A, Systematic desensitization, involves gradual exposure to the fear stimulus paired with relaxation techniques. Choice B, Aversion therapy, aims to create a negative association with a stimulus to reduce unwanted behavior. Choice D, Extinction, refers to the gradual decrease in the strength or frequency of a conditioned response.

4. In the 5th substage of sensorimotor development, what does Piaget refer to as 'experimentation,' where the infant tries out new ways of playing with or manipulating objects?

• A. Short-term memory
• B. Working memory
• C. Core memories
• D. Long-term memory

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.

5. A predisposition toward developing a disorder is termed a __________ .

• A. Diathesis
• B. Risk factor
• C. Sufficient cause
• D. Diathesis

Correct answer: A

Rationale: A predisposition toward developing a disorder is termed a diathesis. In this context, diathesis refers to an individual's susceptibility or predisposition to developing a disorder. A diathesis is not the same as a risk factor or a sufficient cause. A risk factor is a variable that increases the likelihood of developing a disorder but is not a predisposition itself. A sufficient cause is a factor that can produce the disorder on its own, not just a predisposition.
