Growth and Development Exam

1. The yolk sac __________.

Correct answer: C

Rationale: The yolk sac is an extraembryonic membrane that plays a significant role in the early development of the embryo. One of its functions is to produce blood cells until the organs are mature enough to take over this function. This process occurs during the early stages of prenatal development to support the growing embryo before it can sustain itself independently.

2. Konrad Lorenz and Niko Tinbergen laid the modern foundations for __________.

Correct answer: A

Rationale: Konrad Lorenz and Niko Tinbergen are considered the founders of ethology, a branch of biology and psychology that focuses on the study of animal behavior in natural environments. Their work laid the modern foundations for ethology, which examines the behavior of animals in relation to their natural habitats and evolutionary history. Choice B, social learning theory, is incorrect as it pertains to a different area of psychology that focuses on how people learn through observing others. Choice C, psychoanalytic theory, is also incorrect as it is a psychological theory developed by Sigmund Freud that emphasizes the role of unconscious conflicts in determining behavior. Choice D, cognitive-developmental theory, is incorrect as it refers to the work of Jean Piaget in understanding the development of human cognition in children.

3. How can families prevent escalating demands that lead to chaos?

Correct answer: D

Rationale: High-quality child care that is affordable and reliable can help prevent escalating demands on families that lead to chaos. This is achieved by providing a stable and supportive environment for children, enabling parents to balance work and family responsibilities effectively. Access to reliable child care reduces stress and helps in preventing chaos within the family, ultimately leading to improved well-being for both parents and children. Choices A, B, and C are incorrect as they do not directly address the need for external support to manage family demands and prevent chaos. Parental multitasking, eating separate meals, and compressing family routines may not provide the necessary stability and support required to prevent escalating demands on families.

4. 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.

5. Cindy tells her daughter, “I know you can do a good job on that homework” because she believes that if she encourages persistence, her daughter will start to view herself as hardworking and high-achieving. Cindy is applying the __________ approach.

Correct answer: D

Rationale: Cindy is applying the social-cognitive approach by encouraging her daughter to believe in her own abilities and persist in her efforts. This approach emphasizes the importance of social influences and cognitive processes in shaping behavior. By providing positive reinforcement and fostering a belief in her daughter's capabilities, Cindy is helping to shape her daughter's self-perception and motivation to achieve success.
