1. Who believed that complex mental activities have their origins in social interaction?

• A. Jean Piaget
• B. Renée Baillargeon
• C. Noam Chomsky
• D. Lev Vygotsky

Correct answer: D

Rationale: The correct answer is Lev Vygotsky. Vygotsky emphasized the role of social interaction and cultural tools in the development of higher cognitive functions. Jean Piaget focused more on individual cognitive development stages, Renée Baillargeon is known for her work in infant cognition and object permanence, and Noam Chomsky is renowned for his theories in linguistics and the study of language.

2. An inadequate diet during pregnancy can __________.

• A. lead to higher birth weight and greater brain weight
• B. reduce the risk of pregnancy-induced maternal diabetes
• C. distort the structure of the liver, kidney, and pancreas
• D. lead to fewer physical discomforts in the final weeks Answer: C Page Ref: 88 Skill Level: Understand Topic: Prenatal Environmental Influences Difficulty Level: Moderate

Correct answer: C

Rationale: An inadequate diet during pregnancy can lead to the distortion of the structure of the liver, kidney, and pancreas in the developing fetus. Proper nutrition during pregnancy is crucial for the healthy development of these organs and essential for the overall well-being of the baby. A balanced diet supports optimal growth and development, while inadequate nutrition can have detrimental effects on the baby's organs and long-term health.

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

• A. implantation occurs
• B. pregnancy does not occur
• C. it stops growing
• D. the cells of the zygote first duplicate

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.

4. Liz is 36 weeks pregnant. A rise in her baby's heart rate is probably followed within five seconds by __________.

• A. a burst of motor activity
• B. a period of sleep
• C. a rise in Liz's heart rate
• D. a drop in Liz's body temperature

Correct answer: A

Rationale: A rise in the baby's heart rate during pregnancy is usually followed within five seconds by a burst of motor activity. This indicates that the baby is responding to stimuli and is an important sign of healthy fetal development. A period of sleep, a rise in Liz's heart rate, or a drop in Liz's body temperature are not typically immediate responses to changes in the baby's heart rate. Sleep is less likely to be a direct response to changes in heart rate, Liz's heart rate is independent of the baby's heart rate changes, and a drop in Liz's body temperature is not a common immediate response to fetal heart rate changes.

5. A __________ is a means of building schemes in which an infant who has stumbled onto a new experience caused by his or her own motor activity tries to repeat the event again and again.

• A. sensorimotor reflex
• B. circular reaction
• C. mental representation
• D. goal-directed behavior

Correct answer: B

Rationale: A circular reaction is a process where an infant repeats a specific action to explore and learn about the environment through their own motor activity. This repetition helps the infant to understand the consequences of their actions and build cognitive schemes. Sensorimotor reflex (choice A) refers to automatic responses to stimuli, not a purposeful repetition of actions to learn. Mental representation (choice C) involves internal cognitive structures to represent objects or events in the mind, which is different from the repetitive behavior described in the question. Goal-directed behavior (choice D) is purposeful and intentional, unlike the repetitive nature of circular reactions in infants' learning process.
