1. Observations of imprinting led to which major concept in human development?

• A. adaptation
• B. equilibrium
• C. the critical period
• D. classical conditioning

Correct answer: C

Rationale: Observations of imprinting in animals, such as ducklings following the first moving object they see after hatching, led to the major concept of the critical period in human development. The critical period is a specific time frame during which an organism must experience certain stimuli to develop properly. This concept has been influential in understanding various aspects of human development, such as language acquisition and social attachment. Choices A, B, and D are incorrect. Adaptation refers to adjusting to the environment, equilibrium is about balance in cognitive processes, and classical conditioning is a learning process associated with behaviorism, none of which directly relate to the concept derived from imprinting observations.

2. Professor Higgins is concerned about the findings of a longitudinal study on childhood depression that she conducted between 1985 and 2015 in New York because many of the participants witnessed the terrorist attacks on the World Trade Center. Professor Higgins is concerned about __________ effects.

• A. practice
• B. cross-sectional
• C. dropout
• D. cohort

Correct answer: D

Rationale: The concern Professor Higgins has regarding the findings of the longitudinal study is related to cohort effects. Cohort effects occur when a specific group of individuals experience a common event or circumstance that could influence the results of a study. In this case, the participants witnessing the terrorist attacks on the World Trade Center could have had a significant impact on their development and mental health outcomes, leading to cohort effects observed in the study. Choice A, 'practice,' is incorrect as it refers to the repeated performance of an activity to improve skill. Choice B, 'cross-sectional,' is incorrect as it involves data collection at a single point in time. Choice C, 'dropout,' is incorrect as it refers to participants leaving a study prematurely.

3. Maternal high blood glucose _________.

• A. can cause Rh factor incompatibility
• B. is linked to poorer memory in early childhood
• C. is linked to low birth weight
• D. can cause the mother's blood pressure to increase sharply

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. Fraternal twins are ____________.

• A. genetically identical
• B. no more alike than ordinary siblings
• C. less common than other types of multiple offspring
• D. less likely with each additional birth

Correct answer: B

Rationale: The correct answer is B. Fraternal twins are no more alike than ordinary siblings because they share about 50% of their genes, just like other siblings. Choice A is incorrect as fraternal twins are not genetically identical. Choice C is incorrect as fraternal twins are actually the most common type of multiple offspring. Choice D is incorrect as the likelihood of fraternal twins is not affected by the number of births a mother has had.

5. Under ethical standards, when is deception permitted in research studies?

• A. if the participants are young enough that they would not understand the deception
• B. if investigators satisfy institutional review boards that such practices are necessary
• C. if researchers can observe participants from behind one-way mirrors
• D. if the participants give informed consent and the researchers never reveal the real purpose of the study

Correct answer: B

Rationale: Ethical standards permit deception in research studies if investigators satisfy institutional review boards that such practices are necessary. Institutional review boards are responsible for ensuring that research studies comply with ethical guidelines and protect the welfare of study participants. Deception should only be used when necessary, and the board's approval indicates that safeguards are in place to minimize harm to participants. Choices A, C, and D are incorrect because ethical deception in research studies is not based on the age of participants, observing from behind mirrors, or obtaining informed consent without revealing the study's real purpose.
