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. During which span of months or years is a child particularly responsive to specific forms of experience or influenced by their absence?

• A. Nonnormative influences
• B. Normative age-graded influence
• C. Normative history-graded influence
• D. Sensitive period

Correct answer: D

Rationale: The correct answer is 'Sensitive period.' A sensitive period refers to a specific span of time during development when a child is especially responsive to certain experiences. This period allows for optimal development in specific areas. Nonnormative influences (Choice A) are events that are irregular and unpredictable, while normative age-graded influences (Choice B) are typical events that occur in a similar manner for most people in a specific age group. Normative history-graded influences (Choice C) are events that most people in a specific culture or cohort experience at the same time.

3. Roger has suffered a major brain injury. As a result, he is unable to speak fluently, tends to mispronounce words, and speaks haltingly. For instance, he says 'wat' instead of 'watch' and 'tot' instead of 'talk.' What is the diagnosis?

• A. Agnosia
• B. Spatial neglect
• C. Broca's aphasia
• D. Prosopagnosia

Correct answer: C

Rationale: The correct diagnosis for Roger's condition is Broca's aphasia. Broca's aphasia is characterized by difficulty in speaking fluently and accurately, often due to brain injury. In this case, Roger's symptoms of being unable to speak fluently, mispronouncing words, and speaking haltingly align with the characteristics of Broca's aphasia. Agnosia refers to the inability to recognize or interpret sensory information, spatial neglect is the lack of awareness of one side of the body or space, and prosopagnosia is the inability to recognize faces, none of which match Roger's symptoms.

4. Which field of psychology studies attitude change and group behavior?

• A. Developmental psychology
• B. Social psychology
• C. Psychoanalysis
• D. Psychometrics

Correct answer: B

Rationale: The correct answer is B: Social psychology. Social psychology specifically focuses on studying topics like attitude change and group behavior. Developmental psychology (Choice A) primarily deals with human growth and development across the lifespan. Psychoanalysis (Choice C) is a theoretical approach to psychology developed by Sigmund Freud focusing on the unconscious mind and childhood experiences. Psychometrics (Choice D) involves the measurement of psychological variables such as intelligence, personality traits, and abilities.

5. What is the term for a fluid-filled sac in which the baby floats until just before it is born?

• A. Amnion
• B. Placenta
• C. Umbilical cord
• D. Embryo

Correct answer: A

Rationale: The correct answer is A: Amnion. The amnion is a fluid-filled sac that surrounds and protects the developing fetus in the womb. It acts as a cushion, maintaining a stable temperature and protecting the fetus from external pressure. Choices B, C, and D are incorrect because the placenta is an organ that provides nutrients and oxygen to the fetus and removes waste products, the umbilical cord connects the fetus to the placenta to facilitate nutrient exchange, and an embryo is an early stage of development before it becomes a fetus.
