1. If learning has occurred in classical conditioning, and the neutral stimulus by itself produces a response similar to the reflexive response, the neutral stimulus is then called a __________.

• A. neutral response
• B. conditioned stimulus
• C. conditioned response
• D. reinforcer

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.

2. By using which method of assignment of participants to treatment conditions, investigators increase the chances that participants' characteristics will be equally distributed across treatment groups?

• A. sequential
• B. random
• C. systematic
• D. correlational

Correct answer: B

Rationale: By using random assignment of participants to treatment conditions, investigators increase the chances that participants' characteristics will be equally distributed across treatment groups. Random assignment helps reduce the likelihood of bias in the selection process and ensures that any differences between groups are due to the treatment and not pre-existing group differences. Sequential, systematic, and correlational assignment methods do not provide the same level of assurance in distributing participants' characteristics equally across treatment groups.

3. According to __________ theory, children learn primarily through modeling.

• A. reinforcement
• B. operant conditioning
• C. social learning
• D. classical conditioning

Correct answer: C

Rationale: According to social learning theory, children primarily learn through modeling, observation, and imitation of others. This theory emphasizes the importance of cognitive processes in learning, as opposed to only focusing on direct reinforcement or punishment. Social learning theory was developed by psychologist Albert Bandura and is a key theory in the field of child development. Choice A, reinforcement, is incorrect as it refers to the process of strengthening a behavior through rewards or punishments. Choice B, operant conditioning, is also incorrect as it is a learning process that involves reinforcement and punishment to shape behavior. Choice D, classical conditioning, is not the correct answer as it involves learning through association between stimuli.

4. The more a mental ability depends on __________ intelligence, the earlier it starts to decline.

• A. fluid
• B. crystallized
• C. emotional
• D. cultural

Correct answer: A

Rationale: The correct answer is A: fluid. Fluid intelligence, which involves problem-solving and reasoning, tends to decline earlier than crystallized intelligence. Crystallized intelligence, on the other hand, involves knowledge and skills acquired over time and is more stable with age. Emotional intelligence and cultural intelligence are not directly related to the decline of mental abilities mentioned in the question, making them incorrect choices.

5. During the second month of pregnancy, __________.

• A. the umbilical cord first appears as a primitive body stalk
• B. touch sensitivity extends to most of the body
• C. the heart develops separate chambers
• D. the heartbeat can be heard through a stethoscope

Correct answer: C

Rationale: During the second month of pregnancy, the heart of the developing fetus begins to develop separate chambers, forming the structure necessary for a fully functioning heart. This is a significant milestone in the prenatal development process. Choices A, B, and D are incorrect because the appearance of the umbilical cord as a primitive body stalk typically occurs around week 5-6, touch sensitivity extending to most of the body is more characteristic of the end of the second trimester, and the heartbeat is usually detectable through a stethoscope around the 18th to 20th week of pregnancy, not during the second month.
