1. In a correlational design, researchers __________.
- A. gather information on individuals without altering their experiences
- B. divide events and behaviors of interest into two types: dependent and independent variables
- C. use an evenhanded procedure to assign people to two or more treatment conditions
- D. directly control or manipulate changes in the independent variable
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. Lily weighed 8 pounds and was 21 inches long at birth. She was __________ than the average baby.
- A. heavier but shorter
- B. heavier and longer
- C. lighter but longer
- D. lighter and shorter
Correct answer: B
Rationale: Lily weighed 8 pounds and was 21 inches long at birth. Being both heavier and longer than average babies typically are at birth, Lily would be considered heavier and longer compared to the average baby. This makes choice B, 'heavier and longer,' the correct answer. Choices A, C, and D are incorrect because Lily was not shorter or lighter than the average baby at birth.
3. When Mateo was born prematurely to Yvonne, a cocaine addict, what can his caregivers expect?
- A. He will be very attentive to the environment
- B. His cries will be abnormally shrill and piercing
- C. He will overcome the harmful effects of drug exposure by age 3
- D. His motor development will be especially rapid during the first year
Correct answer: B
Rationale: Mateo, being born prematurely to a cocaine-addicted mother, is at risk for several health issues. One common effect of prenatal drug exposure is a higher likelihood of sensory and regulatory problems, such as having abnormally shrill and piercing cries. This is a potential outcome that Mateo's caregivers can expect due to his circumstances. Choice A is incorrect as there is no direct correlation between being born prematurely to a cocaine-addicted mother and being very attentive to the environment. Choice C is incorrect as overcoming harmful effects of drug exposure by age 3 is overly optimistic and may not be the case for all children exposed to drugs prenatally. Choice D is incorrect as rapid motor development is not typically associated with prenatal drug exposure.
4. What advice can you offer parents who want to reduce their newborn son’s discomfort during circumcision?
- A. Stimulate the Babinski reflex.
- B. Play loud music to distract the baby.
- C. Offer a sugar solution while gently holding the baby.
- D. Newborns have a low sensitivity to pain, so interventions are unnecessary. Answer: C Page Ref: 108 Skill Level: Apply Topic: The Newborn Baby’s Capacities Copyright © 2018 Laura E. Berk. All Rights Reserved. 35 Test Bank for Berk, Development Through the Lifespan, 7e Difficulty Level: Difficult
Correct answer: C
Rationale: Offering a sugar solution while gently holding the baby can help reduce the newborn's discomfort during circumcision. This method has been found to effectively decrease pain perception and can provide some comfort to the baby during the procedure. Stimulating the Babinski reflex, playing loud music to distract the baby, and assuming newborns have low sensitivity to pain are not recommended strategies for reducing discomfort during circumcision.
5. Charles Darwin's theory of evolution emphasized __________ and __________.
- A. the normative approach; survival of the fittest
- B. noble savages; physical maturation
- C. tabula rasa; natural selection
- D. natural selection; survival of the fittest
Correct answer: D
Rationale: Charles Darwin's theory of evolution emphasized natural selection and survival of the fittest. Natural selection is the process by which organisms with traits that help them survive and reproduce in their environment are more likely to pass on these traits to their offspring. Survival of the fittest refers to the idea that the organisms best adapted to their environment are more likely to survive and reproduce, leading to the gradual evolution of species over time. Both concepts are central to Darwin's theory of evolution. Choices A, B, and C are incorrect as they do not accurately reflect the key principles highlighted by Darwin in his theory of evolution.
