Defense mechanisms ________.

Correct Answer: D

Rationale: The correct answer is D because defense mechanisms aim to reduce anxiety but can lead to distortion of reality, making them not always beneficial. Choice A is incorrect as defense mechanisms are meant to reduce anxiety, not increase it. Choice B is incorrect because defense mechanisms are not strategies of the id specifically. Choice C is incorrect as defense mechanisms are often unconscious and not always intentional.

Correct Answer: B

Rationale: Freud's major contribution to current perspectives of mental disorders is the concept of the unconscious and its influence on behavior. While the Oedipal complex (Choice A) and Electra complex (Choice C) are important psychoanalytic concepts introduced by Freud, they are more focused on childhood psychosexual development rather than mental disorders. The understanding of the three structures of personality (Choice D) refers to Freud's id, ego, and superego model, which is essential in psychoanalytic theory but not specifically related to mental disorders.

Correct Answer: A

Rationale: The correct answer is A: biopsychosocial. The biopsychosocial viewpoint considers the interplay of biological, psychological, and social factors in understanding mental illnesses. This model recognizes that mental health and illness are influenced by a combination of biological, psychological, and social factors. Choice B, sociocultural, focuses more on societal and cultural influences on mental health, while Choice C, Gestalt, relates to holistic psychology. Choice D, neuroscience, emphasizes the role of the nervous system and brain in mental processes, but it does not encompass the broader integration of biological, psychological, and social aspects seen in the biopsychosocial viewpoint.

Correct Answer: B

Rationale: The synapse is the correct answer. It is the site where communication between neurons occurs through the release and reception of neurotransmitters. Choice A, neuron, is incorrect as it is the cell itself rather than a specific site of communication. Choice C, axon, is also incorrect as it is a part of the neuron that transmits signals away from the cell body. Choice D, dendrite, is not the correct answer either, as dendrites receive signals from other neurons but do not release neurotransmitters for communication.

Correct Answer: B

Rationale: The correct answer is B: 'less cortical gray matter than those raised by their parents.' Studies have shown that children raised in orphanages tend to have less cortical gray matter compared to those raised by their parents. This is due to the lack of individualized care, attention, and stimulation that can negatively impact brain development. Choices A, C, and D are incorrect because there is no direct correlation between cortical gray matter and the number of friendships when comparing children raised in orphanages and those raised by their parents.
