Psychology 101 Exam 3 Test

1. What are genes made of?

Correct answer: C

Rationale: Genes are made of DNA, which is the genetic material that carries the instructions for the development, functioning, growth, and reproduction of organisms. While chromosomes contain genes, they are not what genes themselves are made of. Proteins are involved in gene expression and regulation, but they are not the primary material genes consist of. Trisomes is an incorrect term in this context and does not relate to the composition of genes.

2. Distinguish between assimilation and accommodation.

Correct answer: B

Rationale: The correct answer is B. Assimilation is when new experiences are interpreted in terms of existing schemas, meaning individuals try to fit new information into their pre-existing understanding of the world. Accommodation, on the other hand, involves adjusting our schemas to fit new information, which means changing our existing mental frameworks when new information doesn't fit. Choice A is incorrect because it describes accommodation rather than assimilation. Choice C is incorrect as it confuses assimilation with social adaptation. Choice D is incorrect as assimilation and accommodation are fundamental processes in cognitive development, as described by Piaget.

3. Which of the following statements about brain dysfunction and psychiatric disorders is correct?

Correct answer: C

Rationale: The correct statement is C: 'Changes in brain function appear to play a role in many psychiatric disorders.' This statement is accurate as research suggests that alterations in brain function are associated with various psychiatric disorders. Option A is incorrect because while brain damage can contribute to some psychiatric conditions, it is not always the primary cause. Option B is incorrect as brain damage typically increases the risk of developing psychiatric disorders. Option D is incorrect because while brain development can be influenced by experiences, it does not always decrease the risk of psychiatric conditions.

4. Neural plasticity is ________.

Correct answer: B

Rationale: Neural plasticity refers to the brain's flexibility to change existing neural circuits or create new ones. Choice A is incorrect as it describes neurotransmitter breakdown, not neural plasticity. Choice C is incorrect because neural plasticity does not necessarily indicate brain damage leading to mental disorders. Choice D is incorrect because neural plasticity is not specifically related to temperament or personality development in children.

5. What is a set of age norms defining a sequence of life experiences that is considered normal in a given culture and that all individuals in that culture are expected to follow, which may lead to ____?

Correct answer: B

Rationale: The correct answer is B: Social clock; ageism. A social clock refers to the normal sequence of life events in a culture, and not meeting these norms can result in ageism. Choice A is incorrect because normative age-graded influence is not directly related to sexism. Choice C is incorrect as critical period refers to specific time frames for development, not a set of age norms. Choice D, sensitive period, does not directly relate to the concept described in the question.
