Human Growth and Development Final Exam Answers

1. What did Ivan Pavlov discover?

Correct answer: B

Rationale: Ivan Pavlov discovered classical conditioning. This is a form of learning in which a neutral stimulus becomes associated with a meaningful stimulus and acquires the capacity to elicit a similar response. Pavlov's famous experiment with dogs, where he conditioned them to salivate at the sound of a bell, demonstrated this principle. Choices A, C, and D are incorrect because Pavlov's work primarily focused on classical conditioning, not observational learning, ego contributions to development, or the clinical method.

2. Which of the following is a self-conscious emotion?

Correct answer: A

Rationale: The correct answer is A, guilt. Guilt is a self-conscious emotion that involves reflecting on one's actions and feeling remorse. Self-conscious emotions are those that require self-reflection and self-evaluation. Choices B, C, and D are not self-conscious emotions. Happiness and fear are not self-conscious emotions as they do not necessarily involve self-reflection. Interest is not a self-conscious emotion but rather a feeling of curiosity or attraction towards something.

3. Maternal high blood glucose _________.

Correct answer: B

Rationale: Maternal high blood glucose is linked to poorer memory in early childhood. Research has shown that exposure to high levels of maternal blood glucose during pregnancy may negatively impact a child's memory development in early childhood. This highlights the importance of managing blood glucose levels during pregnancy for the health and development of the child. Choices A, C, and D are incorrect because they do not reflect the established link between maternal high blood glucose and poorer memory in early childhood. Rh factor incompatibility is related to blood type differences between the mother and the fetus, low birth weight can be linked to various factors other than maternal blood glucose, and sharp increases in the mother's blood pressure are not directly associated with maternal high blood glucose.

4. When the blastocyst burrows deep into the uterine lining, __________.

Correct answer: A

Rationale: When the blastocyst burrows deep into the uterine lining, this process is known as implantation. Implantation is a crucial step in the early stages of pregnancy where the blastocyst attaches to the uterine wall in order to receive nourishment and continue developing. Choice B is incorrect because implantation is a necessary step for pregnancy to occur. Choice C is incorrect as implantation marks the beginning of further growth and development. Choice D is incorrect as the duplication of cells occurs during earlier stages of development, not during implantation.

5. Men with even tiny amounts of dioxin in their bloodstream father __________.

Correct answer: A

Rationale: Men with even tiny amounts of dioxin in their bloodstream father nearly twice as many girls as boys. This is due to the impact of dioxin exposure on sperm cells, leading to a skewed ratio of female to male offspring. Choice B is incorrect as the question specifically mentions that men father more girls than boys. Choice C is incorrect as dioxin exposure does not necessarily lead to more twins and triplets. Choice D is incorrect as men with dioxin in their bloodstream father more girls, not fewer children overall.
