Which psychosexual stage focuses on castration anxiety?

Correct Answer: D

Rationale: Castration anxiety is a concept from Freudian psychoanalytic theory that occurs during the Phallic stage. This stage occurs between 3 to 6 years of age and is when children experience conflicts related to the Oedipus complex (boys) and Electra complex (girls). During this stage, children may fear castration (in boys) or penis envy (in girls), which are crucial components of castration anxiety. Therefore, the correct answer is Phallic. The other options (A: Genital, B: Oral, C: Anal) are incorrect as they do not specifically involve castration anxiety but rather represent different stages in Freud's psychosexual development theory.

Correct Answer: B

Rationale: When examining heredity and mental disorders, it is important to note that these conditions are influenced by multiple genes working together. Mental disorders are complex traits that arise from the interplay of various genetic and environmental factors. Therefore, choice B, 'influenced by multiple genes,' is the correct answer. Choice A, 'influenced by one particular gene,' is incorrect because mental disorders typically do not result from the action of a single gene. Choice C, 'influenced by recessive genes,' is incorrect as it oversimplifies the genetic basis of mental disorders. Choice D, 'not influenced by genes,' is also incorrect as genes play a significant role in the development of mental disorders.

Correct Answer: C

Rationale: The correct answer is C: 'Interaction between genetics and environment.' The genetic study of identical twins reared apart helps in understanding how both genetics and environment play a role in shaping an individual's traits and behaviors. This type of study allows researchers to tease apart the effects of genetic inheritance from those of environmental influences. Choices A, B, and D are incorrect because the study of identical twins reared apart specifically focuses on the interplay between genetics and environment, rather than solely on differences in brain function, genetic influence on behavior, or the role of environmental factors alone.

Correct Answer: C

Rationale: The correct answer is C. The authoritative parenting style is characterized by a balance of warmth, control, and communication. This style promotes a nurturing environment where rules are established, but there is also room for open communication and understanding. Choice A, Authoritarian, is characterized by high control and low warmth, with strict rules and limited communication. Choice B, Permissive/indulgent, is characterized by high warmth and low control, with few rules and little discipline. Choice D, Neglectful/uninvolved, is characterized by low warmth, low control, and lack of communication or involvement in the child's life.

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.
