Correct Answer: A

Rationale: The correct answer is A: Qualitative change. Qualitative change aligns with the discontinuity view by involving changes in type or kind. This contrasts with quantitative change (B), which is about changes in amount or quantity. Maturation (C) refers to the process of becoming fully developed in a particular way, and multidirectional development (D) emphasizes that development involves both gains and losses, not specifically focusing on changes in type or kind.

Correct Answer: C

Rationale: The correct answer is C: Self-conscious emotions. Self-conscious emotions like pride, shame, and guilt require not only self-awareness but also an understanding of socially accepted behaviors. These emotions involve evaluating oneself in relation to societal norms. Choices A, B, and D are incorrect because they do not accurately capture the idea of emotions that rely on both self-awareness and knowledge of socially accepted standards of behavior.

Correct Answer: B

Rationale: Selective mutism can coexist with social anxiety disorder. The correct answer is B because it is incorrect to say that selective mutism cannot be diagnosed alongside social anxiety disorder. Statement A is true as selective mutism is often associated with high social anxiety. Statement C is true as individuals with selective mutism can speak in some situations. Statement D is true as selective mutism may lead to academic impairment due to difficulties in communication.

Correct Answer: C

Rationale: According to the diathesis-stress model, having a predisposition towards mental illness increases the risk but does not guarantee the development of a mental disorder. Choice A is incorrect as the model does not imply certainty. Choice B is incorrect as having a predisposition does affect the chances. Choice D is incorrect as the model does have an impact on the likelihood of developing a mental disorder.

Correct Answer: B

Rationale: Recessive traits are expressed when an individual inherits two copies of the recessive gene, one from each parent. Therefore, the correct answer is B. Choice A is incorrect as one copy of a recessive gene is not sufficient to display a recessive trait. Choice C is incorrect because having at least one copy of a dominant gene is unrelated to expressing a recessive trait. Choice D is incorrect because two copies of a recessive gene must come from both parents, not just one.
