Human Growth and Development Exam 1

1. Before the late 1800s, childbirth usually took place __________.

A. at home and was a family-centered event
B. at home, but away from other family members
C. in a hospital with trained midwives
D. in the home of a medical professional or in a hospital

Correct answer: A

Rationale: Before the late 1800s, childbirth usually took place at home and was a family-centered event. During this period, most women gave birth at home with the help of family members and possibly a midwife. Hospitals were not common settings for childbirth at that time. Choice B is incorrect because childbirth was not typically done away from family members. Choice C is incorrect because hospitals were not the common setting for childbirth before the late 1800s. Choice D is incorrect because giving birth in the home of a medical professional or a hospital was not the norm during that period.

2. 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.

3. During prenatal development, the ectoderm folds over to form the __________, or primitive spinal cord.

A. mesoderm; neuron tract
B. neural tube
C. endoderm; neural tube
D. neuron tract

Correct answer: B

Rationale: The correct answer is B. During prenatal development, the ectoderm folds over to form the neural tube, which eventually develops into the brain and spinal cord. The neural tube is the precursor to the central nervous system, including the primitive spinal cord. Choices A, C, and D are incorrect because the mesoderm does not form the neural tube, the endoderm is not involved in the formation of the central nervous system, and neuron tract is not the structure that forms the primitive spinal cord.

4. Evolutionary developmental psychology __________.

A. focuses on how the structures of the mind develop to better fit with, or represent, the external world
B. seeks to understand the adaptive value of species-wide competencies as those competencies change with age
C. views the human mind as a symbol-manipulating system through which information flows
D. brings together researchers from many fields to study changes in the brain and behavior patterns

Correct answer: B

Rationale: Evolutionary developmental psychology seeks to understand the adaptive value of species-wide competencies as those competencies change with age. This field focuses on how psychological traits and behaviors have evolved to enhance survival and reproduction over time. It emphasizes the interaction between evolutionary principles and developmental processes to provide insights into human behavior and cognition. Choices A, C, and D are incorrect because they do not accurately describe the primary focus of evolutionary developmental psychology. Choice A is more aligned with cognitive psychology, choice C relates to cognitive science, and choice D could pertain to multidisciplinary approaches but not specifically to evolutionary developmental psychology.

5. What did Ivan Pavlov discover?

A. observational learning
B. classical conditioning
C. the ego's positive contributions to development
D. the clinical method

Correct answer: B

Rationale: Ivan Pavlov discovered classical conditioning. This is a form of learning in which a neutral stimulus becomes associated with a meaningful stimulus and acquires the capacity to elicit a similar response. Pavlov's famous experiment with dogs, where he conditioned them to salivate at the sound of a bell, demonstrated this principle. Choices A, C, and D are incorrect because Pavlov's work primarily focused on classical conditioning, not observational learning, ego contributions to development, or the clinical method.
