1. Which statement is supported by research on newborn taste preferences?
- A. Newborns cannot distinguish basic tastes.
- B. Not until 4 months do babies prefer a salty taste to plain water.
- C. Newborns prefer the taste of formula to breast milk.
- D. Unlike adults, babies relax their facial muscles in response to sour tastes.
Correct answer: B
Rationale: Research on newborn taste preferences has found that not until around 4 months of age do babies start to show a preference for a salty taste over plain water. This indicates that newborns do have some ability to distinguish tastes, contrary to the statement in option A. The statement in option C that newborns prefer the taste of formula to breast milk is not supported by research on newborn taste preferences. Option D, stating that babies relax their facial muscles in response to sour tastes, is also not a supported statement regarding newborn taste preferences.
2. Dana is pregnant with her first child and wonders how much weight she should gain during the pregnancy. You should recommend a healthy diet that results in a weight gain of __________ pounds.
- A. 10 to 15
- B. 15 to 20
- C. 25 to 30
- D. 35 to 40
Correct answer: C
Rationale: The recommended weight gain during pregnancy depends on the pre-pregnancy weight of the mother. For a woman with a normal pre-pregnancy BMI, the recommended weight gain is typically between 25 to 30 pounds. This range is considered healthy to support the growth and development of the baby while also maintaining the mother's health. Choices A, B, and D are incorrect as they represent weight gain ranges that are either too low or too high for a woman with a normal pre-pregnancy BMI, which could pose health risks for both the mother and the baby. It is crucial to adhere to healthcare professionals' guidelines to ensure a healthy pregnancy and birth outcome.
3. What is the goal of applied behavior analysis?
- A. outline changes in temperament over the lifespan
- B. eliminate undesirable behaviors and increase desirable responses
- C. examine how we think about ourselves and other people
- D. synthesize information from various sources into a detailed picture of a person's personality
Correct answer: B
Rationale: The correct answer is B: "eliminate undesirable behaviors and increase desirable responses." Applied behavior analysis aims to modify behavior by focusing on eliminating unwanted behaviors and reinforcing desirable ones. It does not primarily deal with changes in temperament (choice A), self-perception (choice C), or personality traits (choice D). The approach involves techniques such as reinforcement to target specific behaviors, rather than broader cognitive processes or personality characteristics.
4. By the twelfth week of pregnancy, __________.
- A. the sex of the fetus can be detected with ultrasound
- B. the mother can feel the movements of the fetus
- C. the fetus is viable and can survive if born early
- D. synchrony between fetal heart rate and motor activity peaks Answer: A Page Ref: 79 Skill Level: Understand Copyright © 2018 Laura E. Berk. All Rights Reserved. 6 Test Bank for Berk, Development Through the Lifespan, 7e Topic: Prenatal Development Difficulty Level: Moderate
Correct answer: A
Rationale: By the twelfth week of pregnancy, the sex of the fetus can be detected with ultrasound. Ultrasound technology allows for visualization of the developing fetus and identification of physical characteristics, such as sex, during prenatal appointments.
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.
