1. 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.

2. The most rapid prenatal changes take place in the period of the __________.

• A. zygote
• B. blastocyst
• C. embryo
• D. fetus

Correct answer: C

Rationale: The correct answer is C: embryo. The most rapid prenatal changes occur during the embryo stage, which spans from approximately 2 to 8 weeks after conception. This period is crucial as major organs and systems of the body develop rapidly, laying the foundation for future growth and development. The zygote stage is the initial single-celled entity formed by the union of sperm and egg, while the blastocyst stage involves the cluster of cells resulting from the zygote dividing and growing. The fetus stage follows the embryo stage and focuses on refining and growing existing structures rather than rapid development. Therefore, the embryo stage is where the most significant and rapid changes take place in prenatal development.

3. At Kohlberg's Stage __________, individuals can imagine alternatives to their own social order, and they emphasize fair procedures for interpreting and changing the law.

• A. 3, the 'good boy/good girl' orientation
• B. 4, the social-order-maintaining orientation
• C. 5, the social contract orientation
• D. 6, the universal ethical principle orientation

Correct answer: C

Rationale: The correct answer is C: '5, the social contract orientation.' At Kohlberg's Stage 5, individuals begin to question their own social order and focus on principles of justice and fairness. This stage emphasizes the importance of social contracts and agreements based on mutual benefit. Choice A is incorrect as the 'good boy/good girl' orientation is characteristic of Stage 3. Choice B, the social-order-maintaining orientation, does not align with the description provided in the question. Choice D, the universal ethical principle orientation, is associated with Stage 6, where individuals act based on self-chosen ethical principles.

4. Which of the following is the best available predictor of infant survival and healthy development?

• A. Birth length
• B. Combined Apgar score
• C. Delivery date
• D. Birth weight

Correct answer: D

Rationale: The correct answer is 'Birth weight.' Birth weight is a crucial indicator of an infant's chances of survival and well-being. Low birth weight is associated with various health risks and developmental challenges. Birth length (choice A) is not as significant in predicting infant outcomes as birth weight. The Combined Apgar score (choice B) is a measure of the newborn's health status at birth, not a predictor of long-term survival and development. Delivery date (choice C) is important for determining gestational age but is not as directly related to infant survival and healthy development as birth weight.

5. Dr. McBride wants to know if the teacher's use of encouragement in the classroom affects the children's self-esteem. To assign children to treatment conditions, Dr. McBride should __________.

• A. carefully distribute the children according to their test scores
• B. divide the children so each group has an equal number of boys and girls
• C. draw the children's names out of a hat
• D. assign the quieter children to the same treatment condition

Correct answer: C

Rationale: Drawing the children's names out of a hat is a way to randomly assign them to treatment conditions. Random assignment helps to ensure that any differences in self-esteem that may be observed in the study are not due to pre-existing characteristics of the children. This method helps to establish a cause-and-effect relationship between the teacher's use of encouragement and the children's self-esteem. Choice A is incorrect because assigning children based on test scores may introduce bias into the study. Choice B is incorrect as balancing gender is not relevant to the research question. Choice D is incorrect as it introduces a bias by selecting a specific group of children based on a characteristic unrelated to the study objective.
