infant characteristics

ATI RN

Psychology 101 Exam 3 Test

1. Infant characteristics ________.

A. do not affect parental behavior.
B. only affect parental behavior when psychopathology is present.
C. are not influenced by biological factors.
D. can influence the quality of attachment relationships.

Correct answer: D

Rationale: Infant characteristics can indeed influence the quality of attachment relationships. Parents often respond to their infants based on their characteristics, temperament, and needs. This interaction shapes the attachment bond between the parent and the child. Choices A, B, and C are incorrect because infant characteristics do have an impact on parental behavior and are influenced by various factors, including biological ones.

2. 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.

3. Which part of your brain is active when you get cues about being hungry, thirsty, or sleepy?

A. Hippocampus
B. Thalamus
C. Hypothalamus
D. Amygdala

Correct answer: C

Rationale: The correct answer is the Hypothalamus (Choice C). The hypothalamus plays a crucial role in regulating basic bodily functions such as hunger, thirst, and sleep. It receives cues related to these needs and helps to maintain homeostasis in the body. The Hippocampus (Choice A) is primarily involved in memory formation and spatial navigation, not in regulating physiological needs. The Thalamus (Choice B) acts as a relay station for sensory information but is not the main center for hunger, thirst, or sleep regulation. The Amygdala (Choice D) is more associated with emotions, particularly fear and pleasure, rather than physiological needs like hunger, thirst, or sleep.

4. Normal human cells have ________.

A. twenty-two chromosome pairs and one pair of sex chromosomes.
B. twenty-one trisomy chromosome pairs, one autosomal pair, and one pair of sex chromosomes.
C. twenty-one chromosome pairs and two trisomy chromosome pairs.
D. twenty-three chromosome pairs.

Correct answer: A

Rationale: The correct answer is A. Normal human cells have twenty-two chromosome pairs and one pair of sex chromosomes. This adds up to a total of 46 chromosomes. Choice B is incorrect as it mentions twenty-one trisomy chromosome pairs, which is not a characteristic of normal human cells. Choice C is also incorrect as it states twenty-one chromosome pairs and two trisomy chromosome pairs, which is not accurate for normal human cells. Choice D is incorrect as it mentions twenty-three chromosome pairs, which is not the correct number for normal human cells.

5. 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.
