1. In a correlational design, researchers __________.

Correct answer: A

Rationale: In a correlational design, researchers gather information on individuals without altering their experiences. Correlational studies examine the relationship between two or more variables without any manipulation or control by the researchers. The researchers simply observe and measure the variables of interest without intervening in any way. Choices B, C, and D are incorrect because they describe aspects related to experimental designs rather than correlational designs. In an experimental design, researchers manipulate variables, assign participants to different treatment conditions, and control changes in the independent variable, which is not the case in correlational studies.

2. Why do young infants usually cry?

Correct answer: C

Rationale: Young infants usually cry because of physical needs such as hunger, discomfort, or needing to be changed. It is their way of communicating these needs to their caregivers as they are unable to do so in any other way. Choice A is incorrect because infants cry primarily to communicate physical needs, not because they are bored. Choice B is incorrect because the tone of the cry is not the reason why infants cry. Choice D is incorrect because infants cry for various physical needs, not necessarily all night long.

3. Tammy's father is an exceptional gymnast. When Tammy was just a toddler, her father believed that Tammy already showed great promise as a gymnast. Tammy's father probably believes that athletic ability is mostly determined by __________.

Correct answer: C

Rationale: Tammy's father likely believes that athletic ability is mostly determined by nature because he believes she showed great promise at a young age, indicating a natural talent or genetic predisposition towards gymnastics. This suggests that he attributes Tammy's abilities to her inherent qualities rather than her upbringing or experiences (nurture). While stages and early experiences can play a role in skill development, in this context, the emphasis is on innate abilities, making 'nature' the most suitable choice.

4. Prenatally malnourished babies frequently __________.

Correct answer: C

Rationale: Prenatally malnourished babies frequently catch respiratory illnesses. Malnourished babies have weakened immune systems, making them more susceptible to illnesses such as respiratory infections. This is a common consequence that is observed in babies who did not receive adequate nutrition during the prenatal period. Choices A, B, and D are incorrect. While malnourished babies may have feeding challenges, rejecting breast milk is not a common consequence. Enlarged hearts are not typically associated with prenatal malnutrition, and having a higher-than-average birth weight is unlikely in malnourished babies.

5. Regarding a baby’s adaptation to labor and delivery, stress hormones __________. Copyright © 2018 Laura E. Berk. All Rights Reserved. 21 Test Bank for Berk, Development Through the Lifespan, 7e

Correct answer: B

Rationale: Stress hormones during labor and delivery actually help arouse the infant into alertness. These hormones can promote the infant's readiness to adapt to the new environment outside the womb.
