Exam 4 Psychology

Correct Answer: C

Rationale: The correct answer is C. This scenario exemplifies a critical period in development. Critical periods are specific times in an individual's life when certain events have a profound impact on their development. In this case, the events surrounding the departure of the U.S. armed forces from Saigon in 1975 had a lasting influence on the children living there at that time. Choices A, B, and D are incorrect. Normative age-graded influence refers to events that are common to people of a particular age group, the social clock relates to the culturally preferred timing of social events, and a sensitive period is a time when an individual is more susceptible to environmental influences but does not result in lifelong consequences as with critical periods.

Correct Answer: D

Rationale: The correct answer is D, Serotonin. Serotonin levels are reduced during both the manic and depressive phases of bipolar disorder. Acetylcholine (choice A) is not typically linked to bipolar disorder. Dopamine (choice B) and norepinephrine (choice C) are more commonly associated with conditions like schizophrenia and depression, respectively, rather than bipolar disorder. Therefore, they are not the neurotransmitters reduced in both manic and depressive phases of bipolar disorder.

Correct Answer: B

Rationale: The correct answer is B. Telegraphic speech is when a child uses a two-word phrase to convey a larger meaning, such as 'mama water.' Choice A is incorrect as it does not demonstrate telegraphic speech but rather a simple labeling. Choice C is incorrect as it is a complete sentence and not a two-word phrase. Choice D is also incorrect as it does not describe telegraphic speech but rather a vague statement about communication.

Correct Answer: B

Rationale: The correct answer is B. Individuals with bulimia nervosa may maintain a normal body weight, while anorexia nervosa is often associated with severe underweight. Choice A is incorrect because individuals with anorexia nervosa actually face severe health risks due to malnutrition, electrolyte imbalances, and other complications. Choice C is incorrect as anorexia nervosa is characterized by restriction of food intake rather than binge eating. Choice D is incorrect as individuals with anorexia nervosa can also display compensatory behaviors such as excessive exercise or fasting.
