Human Growth and Development Exam 1

1. What is the function of the corpus luteum?

Correct answer: B

Rationale: The correct answer is B. The corpus luteum is a temporary endocrine structure in the ovary that forms after ovulation. It secretes hormones, particularly progesterone, which help prepare the uterine lining for possible implantation of a fertilized ovum. This process is crucial for maintaining a potential pregnancy. Choices A, C, and D are incorrect. Choice A is inaccurate as fertilization typically occurs in the fallopian tubes. Choice C describes the fallopian tubes, not the corpus luteum. Choice D refers to the ovaries, not specifically the corpus luteum.

2. Which statement about prenatal marijuana exposure is true?

Correct answer: A

Rationale: The correct answer is A: 'It is linked to impulsivity and overactivity.' Prenatal marijuana exposure has been associated with impulsivity and overactivity in children based on research findings. However, lasting consequences of prenatal marijuana exposure are not as well-established compared to other teratogens. Choice B is incorrect because lasting consequences are not firmly established. Choice C is incorrect because studies have shown negative effects of prenatal marijuana exposure. Choice D is incorrect as prenatal marijuana exposure is not primarily linked to physical malformations.

3. A 20-week-old fetus can __________.

Correct answer: A

Rationale: A 20-week-old fetus is able to be stimulated as well as irritated by sounds because by this stage of prenatal development, the fetus's auditory system is already well-developed. It can respond to external sounds and may even startle or move in reaction to loud noises.

4. Babies who spend more time alert are likely to have __________.

Correct answer: B

Rationale: Babies who spend more time alert are likely to have a slight advantage in mental development. Being alert allows babies to engage with their surroundings, explore, and learn, which can contribute to their cognitive development. This is different from social development, which is more related to interactions with others, and not necessarily impacted by the amount of alertness a baby displays. Choices A, C, and D are incorrect because there is no direct correlation between a baby's alertness and their parents' feelings of incompetence, a big disadvantage in social development, or the effort parents need to soothe them.

5. Vygotsky saw __________ as the foundation for all higher cognitive processes.

Correct answer: B

Rationale: Corrected Rationale: Vygotsky believed that language plays a crucial role in the development of higher cognitive functions. Language enables individuals to communicate, think abstractly, and engage in complex problem-solving, forming the foundation for higher cognitive processes. Egocentrism (Choice A) refers to a stage in Piaget's theory of cognitive development, not Vygotsky's. Sensorimotor activity (Choice C) is part of Piaget's stages of cognitive development, focusing on how infants understand the world through sensory experiences and physical actions. Self-reflection (Choice D) involves introspection and examination of one's thoughts and feelings, which is not the central concept in Vygotsky's theory.
