1. Researchers randomly assigned adolescents to either a single-grade classroom or a mixed-age classroom. This is an example of a __________.

• A. naturalistic observation
• B. case study
• C. natural experiment
• D. field experiment

Correct answer: D

Rationale: In this scenario, the researchers randomly assigned adolescents to either a single-grade classroom or a mixed-age classroom, which is an example of a field experiment. A field experiment involves manipulating independent variables in a natural setting to observe the effects on participants. This design allows for more control over variables compared to naturalistic observation, case studies, or natural experiments. Naturalistic observation involves observing subjects in their natural environment without manipulating any variables. A case study focuses on in-depth analysis of a single individual or a small group. A natural experiment involves observing naturally occurring events without intervention or manipulation by the researcher.

2. In a longitudinal design, participants are studied repeatedly at different ages, and changes are noted as they get older.

• A. cross-sectional
• B. experimental
• C. longitudinal
• D. correlational

Correct answer: C

Rationale: The correct answer is C: longitudinal. In a longitudinal design, participants are followed and studied over an extended period, allowing researchers to observe changes and continuity in development as individuals age. This design is crucial for understanding how individuals grow and change over time. Cross-sectional studies (Choice A) involve comparing different groups at the same time point, while experimental studies (Choice B) involve manipulating variables to observe their effects. Correlational studies (Choice D) examine relationships between variables but do not involve studying participants over time.

3. In a historic experiment with 11-month-old Albert, John Watson demonstrated that __________.

• A. children cannot be conditioned to fear a formerly neutral stimulus
• B. infants as young as a few months old will repeat a behavior to obtain a desirable reward
• C. children can be conditioned to fear a formerly neutral stimulus
• D. children have an innate, inborn fear of rats Answer: C Page Ref: 16 Skill Level: Understand Topic: Mid-Twentieth-Century Theories Difficulty Level: Moderate

Correct answer: C

Rationale: In the historic experiment with 11-month-old Albert conducted by John Watson, it was demonstrated that children can be conditioned to fear a formerly neutral stimulus. This is known as classical conditioning, where a neutral stimulus is repeatedly paired with an unconditioned stimulus to create a conditioned response. In this case, Albert was conditioned to fear a white rat by pairing the rat with a loud noise. This experiment showcased the power of conditioning in shaping behavior and emotional responses in children.

4. What is a major strength of the longitudinal design?

• A. Examine relationships between early and later behaviors
• B. Collect a large amount of data in a short time span
• C. Explore similarities among children of different cohorts
• D. Study participants differing in age at the same point in time

Correct answer: A

Rationale: A major strength of the longitudinal design is that researchers can examine relationships between early and later behaviors. This design allows researchers to observe and track changes in the same participants over an extended period of time, providing valuable insights into developmental trajectories and how behaviors are connected across different stages of life. Choice B is incorrect because longitudinal studies track changes over time, not necessarily collect a large amount of data in a short time span. Choice C is incorrect as it refers to cross-sectional studies rather than longitudinal studies. Choice D is incorrect as it describes a cross-sectional design where participants of different ages are studied at the same time.

5. Basic emotions __________.

• A. appear in the middle of the second year
• B. are universal in humans
• C. are found only among humans
• D. involve injury to our sense of self

Correct answer: B

Rationale: Basic emotions like happiness, sadness, and anger are universal across humans, meaning they are experienced by people worldwide regardless of cultural differences. These emotions are not limited to a specific group of individuals or exclusive to humans; they are observed in various species. Choice A is incorrect because basic emotions actually appear early in life, not specifically in the middle of the second year. Choice C is incorrect as basic emotions are not exclusive to humans but are observed in other animals as well. Choice D is incorrect because basic emotions do not necessarily involve injury to our sense of self, but rather represent fundamental and instinctual feelings that are part of human nature.
