1. Jalynn is in the last half of the first month of her pregnancy. Which of the following is developing the fastest?
- A. circulatory system
- B. endocrine system
- C. nervous system
- D. skin
Correct answer: C
Rationale: During the last half of the first month of pregnancy, the nervous system develops the fastest among the options provided. This rapid development of the nervous system is crucial for the overall growth and functioning of the fetus. The nervous system includes the brain and spinal cord, which are essential for various bodily functions and will continue to develop throughout the pregnancy. The circulatory system, although important, does not develop at the fastest rate during this stage. The endocrine system and skin also play significant roles in the development of the fetus but are not the systems that develop the fastest in the last half of the first month of pregnancy.
2. In field experiments, researchers __________.
- A. selectively assign participants to treatment conditions in natural settings
- B. cannot use random assignment or manipulate treatment conditions
- C. randomly assign participants to treatment conditions in natural settings
- D. have stronger control over the treatment than in the laboratory
Correct answer: C
Rationale: In field experiments, researchers randomly assign participants to treatment conditions in natural settings. This method allows for a higher level of control over potential confounding variables compared to non-random assignment. Random assignment helps ensure that the groups being compared are comparable at the beginning of the study, which strengthens the internal validity of the research findings. Choice A is incorrect because selective assignment may introduce bias. Choice B is incorrect as researchers can use random assignment in field experiments. Choice D is incorrect because field experiments typically have less control over the treatment compared to laboratory experiments.
3. According to Erikson, if the psychological conflict of adolescence is resolved negatively, a young person experiences __________.
- A. mistrust
- B. isolation
- C. inferiority
- D. role confusion
Correct answer: D
Rationale: Erikson's theory of psychosocial development states that during adolescence, individuals face the conflict of identity vs. role confusion. If this conflict is resolved negatively, adolescents experience role confusion. Role confusion occurs when adolescents fail to develop a clear sense of identity, leading to uncertainty about their future roles. Choices A, B, and C are incorrect because they correspond to earlier stages of Erikson's stages of psychosocial development (mistrust corresponds to infancy, isolation to early adulthood, and inferiority to middle childhood), not adolescence.
4. Dr. Singh believes that a basic psychosocial conflict, which is resolved along a continuum from positive to negative, determines healthy or maladaptive outcomes at each stage of development. Dr. Singh's beliefs are aligned with those of which theorist?
- A. G. Stanley Hall
- B. Sigmund Freud
- C. Erik Erikson
- D. B. F. Skinner
Correct answer: C
Rationale: Dr. Singh's beliefs align with Erik Erikson's psychosocial theory of development. Erikson proposed that individuals go through a series of psychosocial stages, with each stage characterized by a basic conflict that must be resolved to achieve healthy development. This conflict is resolved along a continuum from positive to negative outcomes. Choice A, G. Stanley Hall, is incorrect as his work focused on adolescence and evolutionary psychology. Choice B, Sigmund Freud, is incorrect as his psychoanalytic theory is more focused on the unconscious mind and psychosexual stages. Choice D, B. F. Skinner, is incorrect as he is associated with behaviorism and operant conditioning, which is different from Erikson's psychosocial theory.
5. Terrance, whose birth mother drank heavily throughout pregnancy, has a thin upper lip, short eyelid openings, a small head, and a smooth philtrum. His physical growth has been slow, and he shows impairment in memory, attention span, motor coordination, and social skills. Terrance has __________.
- A. fetal alcohol syndrome
- B. partial fetal alcohol syndrome
- C. alcohol-related neurodevelopmental disorder
- D. cytomegalovirus
Correct answer: A
Rationale: Terrance exhibits a combination of physical abnormalities like a thin upper lip, short eyelid openings, a small head, and a smooth philtrum, along with developmental delays and cognitive impairments. These characteristics are indicative of fetal alcohol syndrome (FAS), which is caused by maternal alcohol consumption during pregnancy. FAS is a severe condition resulting from prenatal alcohol exposure and is characterized by a range of physical, cognitive, and behavioral issues. Choice A, fetal alcohol syndrome, is the correct answer as it aligns with Terrance's symptoms and the effects of maternal alcohol consumption during pregnancy. Choices B, C, and D are incorrect because they do not encompass the full spectrum of symptoms and impairments presented by Terrance, which are specific to fetal alcohol syndrome.
