1. Cross-cultural research on stress demonstrates that ________.

A. Depression is a common response to life challenges in all countries studied.
B. Stress rarely leads to any evidence of illness in non-Western cultures.
C. Responses to stress vary cross-culturally.
D. Culture-specific reactions are not seen to respond to alterations in the environment.

Correct answer: C

Rationale: Cross-cultural research on stress demonstrates that responses to stress vary cross-culturally. Choice A is incorrect because depression being a common response in all countries studied is not supported by cross-cultural research findings. Choice B is incorrect as it generalizes that stress rarely leads to illness in non-Western cultures, which is not universally true. Choice D is incorrect as culture-specific reactions can indeed respond to alterations in the environment, as observed in various cross-cultural studies.

2. How does the concept of neural plasticity relate to recovery from brain injuries?

A. Neural plasticity means the brain cannot recover from injuries.
B. Neural plasticity allows the brain to recover and reorganize after injuries.
C. Neural plasticity refers to the brain's inability to change after injury.
D. Neural plasticity is a myth.

Correct answer: B

Rationale: Neural plasticity allows the brain to recover and reorganize after injuries. It is the brain's ability to adapt and change, forming new connections or reorganizing existing ones to compensate for damage. Choice A is incorrect as neural plasticity enables recovery. Choice C is incorrect as neural plasticity involves the brain's capacity to change. Choice D is incorrect as neural plasticity is a well-established phenomenon in neuroscience.

3. The process of ________ is used to increase the probability that a behavior will occur.

A. operant conditioning
B. reinforcement
C. classical conditioning
D. punishment

Correct answer: B

Rationale: The correct answer is reinforcement. Reinforcement involves providing a consequence that increases the likelihood of a behavior being repeated. Operant conditioning (Choice A) refers to learning through consequences for behavior, which includes reinforcement and punishment. Classical conditioning (Choice C) involves forming associations between stimuli and involuntary responses. Punishment (Choice D) involves providing a consequence that decreases the likelihood of a behavior being repeated. In this context, the question specifically asks about a process that increases the probability of a behavior occurring, aligning with the concept of reinforcement.

4. Down syndrome is caused by ________.

A. a chemical imbalance.
B. a gene on the X chromosome.
C. possessing an extra X chromosome.
D. possessing an extra chromosome in chromosome 21.

Correct answer: D

Rationale: Down syndrome is caused by possessing an extra chromosome in chromosome 21, not by a chemical imbalance (choice A), a gene on the X chromosome (choice B), or possessing an extra X chromosome (choice C). The presence of an additional chromosome 21 disrupts the normal course of development and leads to the characteristics associated with Down syndrome.

5. In the 5th substage of sensorimotor development, what does Piaget refer to as 'experimentation,' where the infant tries out new ways of playing with or manipulating objects?

A. Short-term memory
B. Working memory
C. Core memories
D. Long-term memory

Correct answer: D

Rationale: The correct answer is D, 'Long-term memory.' In the 5th substage of sensorimotor development, Piaget refers to 'experimentation' as tertiary circular reactions, where the infant tries out new ways of playing with or manipulating objects. This stage involves exploring and testing different ways of interacting with the world to understand cause and effect relationships. Choices A, B, and C are incorrect as they do not align with Piaget's concept of tertiary circular reactions and experimentation in the sensorimotor stage of development.
