Correct Answer: C

Rationale: Freud's psychosexual stage that occurs between the ages of 3 and 5, including the Oedipal period, is the phallic stage. During this stage, children experience the Oedipus or Electra complex, where they develop unconscious sexual desires for the opposite-sex parent and see the same-sex parent as a rival. The genital stage (Choice A) is the final stage where mature sexual interests emerge, oral (Choice B) and anal stages precede the phallic stage, and latency (Choice D) is a stage following the phallic stage characterized by a focus on developing social and cognitive skills.

Correct Answer: D

Rationale: The correct answer is D because attributional style plays a crucial role in influencing the likelihood of developing depression by shaping how individuals interpret and respond to events. A positive attributional style can indeed enhance resilience against depression by promoting adaptive coping mechanisms and positive interpretations of situations, which can buffer against the development of depressive symptoms. Conversely, a negative attributional style, characterized by attributing negative events to internal, stable, and global factors, can increase vulnerability to depression by fostering feelings of helplessness and hopelessness. Choices A and C provide accurate insights into how different attributional styles can impact the development of depression, making them incorrect. Choice B is incorrect as research indicates that attributional style does have a significant influence on the likelihood of developing depression.

Correct Answer: B

Rationale: The correct answer is B: Synapse. The synapse is the site where chemical communication occurs between neurons. Neurotransmitters are released from the axon terminal of one neuron, cross the synaptic cleft, and bind to receptors on the dendrites of the next neuron. Choice A, Neuron, is incorrect as it refers to the entire nerve cell. Choices C and D, Axon and Dendrite, are also incorrect as they are specific parts of a neuron and not the primary site of chemical communication.

Correct Answer: B

Rationale: Common methods used to study genetic influences on behavior include twin studies, adoption studies, and gene mapping. Twin studies help to compare the similarities between identical and fraternal twins to estimate the heritability of a trait. Adoption studies look at the similarities between adopted children and their biological and adoptive parents to determine genetic influences. Gene mapping involves identifying specific genes associated with certain behaviors. Choices A, C, and D are incorrect because genetic influences on behavior are not solely studied through twin studies or family history, and while the understanding of genetic influences may vary, there are established methods to study them.

Correct Answer: B

Rationale: The correct answer is B: 'Genes play a role in most mental disorders.' This statement is true as genes do play a significant role in the development of various mental disorders. Choice A is incorrect because most behavioral disorders are influenced by a combination of genetic, environmental, and other factors, not exclusively genes. Choice C is incorrect as genes do affect biochemical processes. Choice D is incorrect because the expression of genes in an individual can be influenced by experiences and environmental factors, a concept known as gene-environment interaction.
