Human Growth and Development Clep Practice Exam

Correct Answer: B

Rationale: The correct answer is B. Fraternal twins are no more alike than ordinary siblings because they share about 50% of their genes, just like other siblings. Choice A is incorrect as fraternal twins are not genetically identical. Choice C is incorrect as fraternal twins are actually the most common type of multiple offspring. Choice D is incorrect as the likelihood of fraternal twins is not affected by the number of births a mother has had.

Correct Answer: C

Rationale: Corrected Rationale: Language development plays a crucial role in emotional self-regulation in preschoolers. It enables children to express and manage their emotions effectively. Choices A and B, permissive and authoritarian child rearing styles, focus more on the parenting approach rather than the child's intrinsic development. Family size, as mentioned in choice D, does not directly contribute to gains in emotional self-regulation.

Correct Answer: A

Rationale: Vygotsky viewed make-believe play as the ideal social context for fostering cognitive development in early childhood. Make-believe play encourages children to explore various roles and scenarios, promoting cognitive and social development. Sensorimotor play focuses on physical interactions with the environment, while block play involves building and construction activities. Parallel play refers to children playing alongside each other without direct interaction, which is not the type of play Vygotsky emphasized for cognitive development.

Correct Answer: B

Rationale: In classical conditioning, when a neutral stimulus triggers the reflexive response, it becomes a conditioned stimulus. Therefore, the correct term for the neutral stimulus that now elicits a response is a conditioned stimulus. Choices A, C, and D are incorrect: A neutral response is not a standard term in classical conditioning; a conditioned response is the learned response to the conditioned stimulus, not the neutral stimulus itself; a reinforcer is a stimulus that follows a behavior and increases the likelihood of that behavior happening again, which is not the same as a conditioned stimulus.

Correct Answer: D

Rationale: The correct answer is D, 'secure.' Research shows that the secure attachment pattern is the most common across various societies. In this pattern, children feel safe, secure, and loved, allowing them to explore the world and seek comfort from their caregivers when needed. Choices A, B, and C are incorrect because while these attachment patterns exist, they are not as prevalent or universal as the secure attachment pattern. Insecure-avoidant attachment involves children avoiding or ignoring their caregiver, insecure-resistant attachment consists of ambivalence and mixed emotions towards the caregiver, and disorganized/disoriented attachment is characterized by inconsistent and often chaotic behaviors towards the caregiver.
