Exam 4 Psychology

1. During conception, the 23 unpaired chromosomes in the ovum and sperm combine to form 23 pairs in an entirely new cell called the?

A. Embryo
B. DNA
C. Fetus
D. Zygote

Correct answer: D

Rationale: The correct answer is D, Zygote. A zygote is formed when the 23 chromosomes from the ovum and sperm combine during conception. It is the initial cell formed and marks the beginning of a new organism. Choice A, Embryo, is incorrect as an embryo is formed later in the development process. Choice B, DNA, is incorrect as DNA is the genetic material within the chromosomes but is not the name of the new cell formed after fertilization. Choice C, Fetus, is incorrect as a fetus is the stage of prenatal development that occurs well after the zygote stage.

2. While the term psychology has existed since at least the early 1700s, psychology did not come to be considered a science until?

A. The 1750s.
B. The early 1800s.
C. The late 1800s.
D. The 1940s.

Correct answer: C

Rationale: Psychology became recognized as a science in the late 1800s, aligning with broader trends in scientific inquiry during that period. This marked the establishment of psychology as a distinct field of study based on empirical research and experimentation. Choices A, B, and D are incorrect because psychology's formal recognition as a science occurred later, specifically in the late 1800s.

3. Which of the following is a common criticism against Piaget's theory of cognitive development?

A. The sequence of stages is not fixed.
B. Research has not supported the existence of the preoperational stage.
C. Piaget put a heavy emphasis on the environment, ignoring the importance of mental processes.
D. Children develop abilities earlier than Piaget theorized.

Correct answer: D

Rationale: The correct answer is D because one common criticism of Piaget's theory is that children often acquire cognitive abilities earlier than Piaget proposed. This criticism suggests that Piaget's stages might not be as fixed or rigid as he believed. Choices A, B, and C are incorrect: A is a characteristic of Piaget's theory; B is not a common criticism, as research generally supports the existence of Piaget's stages; and C is inaccurate, as Piaget actually emphasized the importance of mental processes in cognitive development.

4. What does incidence refer to?

A. How many new cases of a disorder occur during a given period of time
B. How many people have recovered from a disorder in a given period of time
C. The percentage of males and females who have a disorder
D. How many people in the population as a whole have a disorder

Correct answer: A

Rationale: The correct answer is A: 'How many new cases of a disorder occur during a given period of time.' Incidence specifically measures the rate of occurrence of new cases of a particular condition within a defined population and time frame. This distinguishes it from prevalence, which includes both new and existing cases. Choices B, C, and D are incorrect because they do not accurately define the term 'incidence.' Choice B refers to recovery, choice C mentions gender distribution, and choice D relates to the total population affected by a disorder, which are not reflective of the concept of incidence.

5. What are psychology's intellectual parents?

A. Physics and physiology.
B. Philosophy and physiology.
C. Chemistry and physics.
D. Philosophy and chemistry.

Correct answer: B

Rationale: Psychology's intellectual parents are philosophy and physiology. Philosophy contributed to the early development of psychology by exploring questions about the mind and behavior, while physiology provided a scientific foundation for understanding the biological aspects of human psychology. Choices A, C, and D are incorrect as they do not accurately represent the disciplines that significantly influenced the emergence of psychology as a distinct field of study.
