Human Growth and Development Exam 1
1. What is the longest stage of labor?
- A. Delivery of the baby
- B. Delivery of the placenta
- C. Dilation and effacement of the cervix
- D. Release of epinephrine and cortisol
Correct answer: C
Rationale: The correct answer is C: Dilation and effacement of the cervix. This stage can last for hours, especially for first-time mothers, as the cervix needs to dilate and efface to allow for the baby's passage through the birth canal. Once the cervix is fully dilated and effaced, the woman can begin pushing during the second stage of labor to deliver the baby. The delivery of the baby itself is usually a shorter process compared to the time taken for the cervix to dilate and efface. Choices A, B, and D are incorrect because they represent other stages within the labor process that come after the dilation and effacement of the cervix.
2. Developmental social neuroscience __________. Copyright © 2018 Laura E. Berk. All Rights Reserved. 17 Test Bank for Berk, Development Through the Lifespan, 7e
- A. involves the design of flowcharts to map the precise steps individuals use to complete tasks
- B. emphasizes that preschoolers’ thinking is full of faulty logic because they engage in hands-on exploration
- C. is devoted to studying the relationship between changes in the brain and emotional and social development
- D. involves the study of brain activity and the individual’s linear and logical cognitive processing patterns Answer: C Page Ref: 20 Skill Level: Understand Topic: Recent Theoretical Perspectives Difficulty Level: Moderate
Correct answer: C
Rationale: Developmental social neuroscience is dedicated to examining the connection between changes in the brain and emotional and social development. This field of study focuses on how the brain's development influences an individual's social and emotional behavior. By studying brain activity alongside emotional and social development, researchers can gain insights into how these aspects are interrelated and how they impact one another.
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. According to operant conditioning theory, __________.
- A. the frequency of a behavior can be increased through punishment, such as disapproval
- B. normal development must be understood in relation to each culture's life situation
- C. the id develops as parents insist that children conform to the values of society
- D. the frequency of a behavior can be increased by following it with a wide variety of reinforcers
Correct answer: D
Rationale: According to operant conditioning theory, the frequency of a behavior can be increased by following it with a wide variety of reinforcers. In operant conditioning, behaviors are shaped through reinforcement, which can be positive (rewarding) or negative (removal of something unpleasant). By providing reinforcement following a behavior, the likelihood of that behavior occurring again in the future is increased. This supports the notion that the frequency of a behavior can be increased by using reinforcers in operant conditioning. Choices A, B, and C are incorrect because operant conditioning focuses on the relationship between behavior and its consequences through reinforcement (positive or negative) to increase the likelihood of the behavior recurring, rather than punishment, cultural influences, or the development of the id based on societal values.
5. During Irina's first week of pregnancy, __________.
- A. heart muscles begin to develop
- B. the zygote multiplies and forms a blastocyst
- C. a primitive brain and spinal cord appear
- D. the embryo can move
Correct answer: B
Rationale: During the first week of pregnancy, the zygote (fertilized egg) undergoes rapid cell divisions and forms a blastocyst. This is a crucial stage where the cells differentiate and specialize, setting the foundation for the development of the embryo. It is during this time that the zygote implants itself into the uterine wall, initiating the process of pregnancy. Choices A, C, and D are incorrect because during the first week of pregnancy, the focus is on the initial development and multiplication of the zygote, not on the development of heart muscles, a primitive brain and spinal cord, or the embryo's ability to move.
