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. Newer psychodynamic perspectives ________.

A. disregard most elements of Freud's theories.
B. emphasize the role of the id.
C. do not view the libido as a primary determinant of behavior.
D. recognize intrapsychic conflicts as a primary determinant of behavior.

Correct answer: C

Rationale: Newer psychodynamic perspectives do not view the libido as a primary determinant of behavior. While Freud's theories focused heavily on the libido as a driving force, newer perspectives have evolved to consider a broader range of factors influencing behavior. Choice A is incorrect as newer perspectives still build upon some elements of Freud's theories. Choice B is incorrect as newer perspectives may not solely emphasize the role of the id. Choice D is incorrect as while intrapsychic conflicts are considered important, they are not always viewed as the sole primary determinant of behavior in newer psychodynamic perspectives.

3. Which of the following is an example of telegraphic speech?

A. A child pointed to his father's shoe and said 'daddy,' as if to convey 'daddy's shoe.'
B. A thirsty toddler said, 'mama water.'
C. A newborn infant asked, 'Can I have some coffee?'
D. A baby communicated to her parents using her brain.

Correct answer: B

Rationale: The correct answer is B. Telegraphic speech is when a child uses a two-word phrase to convey a larger meaning, such as 'mama water.' Choice A is incorrect as it does not demonstrate telegraphic speech but rather a simple labeling. Choice C is incorrect as it is a complete sentence and not a two-word phrase. Choice D is also incorrect as it does not describe telegraphic speech but rather a vague statement about communication.

4. Alicia, 5 years old, knows that she will take a bath at 6:05, change clothes at 6:15, eat breakfast at 6:20, commute to school at 6:40, and join the assembly at 7:00. A child's awareness of his or her scripts or daily routine is classified under which type of memory?

A. Semantic memory
B. Nondeclarative memory
C. Generic memory
D. Autobiographical memory

Correct answer: D

Rationale: The correct answer is D, Autobiographical memory. Autobiographical memory refers to the memory of a person's life events, such as daily routines and personal experiences. In this scenario, Alicia's awareness of her daily routine falls under autobiographical memory as she remembers specific events related to her own life. Choices A, B, and C are incorrect. Semantic memory is related to general knowledge about the world, nondeclarative memory involves memories that are not consciously recalled, and generic memory is not a recognized memory classification.

5. What does ethnography refer to?

A. A detailed description of a single culture or context
B. Corrupted by original sin
C. The product of evolution
D. A blank slate

Correct answer: A

Rationale: Ethnography refers to a detailed description of a single culture or context. It involves the systematic study and recording of human cultures, including customs, behaviors, and social structures. Choice B, 'Corrupted by original sin,' is incorrect as it does not relate to ethnography. Choice C, 'The product of evolution,' is incorrect as it does not define ethnography. Choice D, 'A blank slate,' is incorrect as it does not describe the practice of ethnography.
