1. In the information-processing system, where does information first enter?

• A. central executive
• B. short-term memory store
• C. sensory register
• D. long-term memory store

Correct answer: C

Rationale: In the information-processing system, information first enters the sensory register. This is where sensory information from the environment is briefly stored before being processed further. The central executive is responsible for coordinating cognitive processes, the short-term memory store holds information temporarily for immediate tasks, and the long-term memory store stores information for long periods, but the sensory register is the initial entry point for incoming information.

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

• A. egocentrism
• B. language
• C. sensorimotor activity
• D. self-reflection

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.

3. Piaget's critics point out that __________.

• A. he overestimated the competencies of infants and young children
• B. his stagewise account pays insufficient attention to social and cultural influences
• C. discovery learning rather than adult teaching is the best way to foster development
• D. children's performances on Piagetian tasks cannot be improved with training

Correct answer: B

Rationale: Piaget's critics point out that his stagewise account pays insufficient attention to social and cultural influences. Critics argue that Piaget's theory does not fully consider the impact of social interactions, cultural differences, and individual experiences on children's cognitive development. They believe that these factors play a crucial role in shaping a child's thinking and problem-solving abilities, which should be given more emphasis. Choice A is incorrect because Piaget's critics do not focus on him overestimating the competencies of infants and young children. Choice C is incorrect as it discusses a different aspect of learning rather than the critique of Piaget's theory. Choice D is also incorrect since critics do not argue that children's performances on Piagetian tasks cannot be improved with training.

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. __________ supplementation early in pregnancy reduces the risk of abnormalities of the neural tube, the circulatory system, and the urinary tract.

• A. Vitamin A
• B. Folic acid
• C. Vitamin D
• D. Vitamin C

Correct answer: B

Rationale: Folic acid supplementation early in pregnancy is crucial as it reduces the risk of abnormalities in the developing fetus. It is specifically known to prevent issues related to the neural tube, circulatory system, and urinary tract. Vitamin A, Vitamin D, and Vitamin C do not play the same role as folic acid in preventing these specific birth defects, making them incorrect choices.
