Human Growth and Development Exam 1
1. 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.
2. Which statement about the newborn baby's appearance is true?
- A. Girls tend to be slightly longer and heavier than boys.
- B. Their round faces and big eyes make adults feel like picking them up.
- C. The trunk is large in comparison to the head, and the legs are straight.
- D. On average, they are 18 inches long and 5½ pounds in weight.
Correct answer: C
Rationale: The correct statement about the newborn baby's appearance is that the trunk is large in comparison to the head, and the legs are straight. This is a common characteristic of newborn babies as their proportions are different from adults. Choice A is incorrect as there is no consistent trend of girls being longer and heavier than boys at birth. Choice B is incorrect as the perception of adults wanting to pick up babies is subjective and not a universal truth. Choice D is incorrect as the average length and weight provided may not apply to all newborn babies, as there can be variations.
3. During her pregnancy, Padma increased her intake of coffee and tea. Her doctor is likely to tell her that high doses of caffeine contained in coffee and tea increase the risk of __________.
- A. premature labor
- B. limb deformities
- C. respiratory distress at birth
- D. low birth weight Answer: D Page Ref: 83 Skill Level: Apply known or suspected teratogens. Topic: Prenatal Environmental Influences Difficulty Level: Difficult
Correct answer: D
Rationale: High doses of caffeine contained in coffee and tea have been linked to an increased risk of low birth weight. Consuming large amounts of caffeine during pregnancy can interfere with the baby's growth and development, leading to a lower birth weight than expected. It is important for pregnant women to limit their caffeine intake to reduce the risk of complications such as low birth weight.
4. 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.
5. According to Erikson, if the psychological conflict of adolescence is resolved negatively, a young person experiences __________.
- A. mistrust
- B. isolation
- C. inferiority
- D. role confusion
Correct answer: D
Rationale: Erikson's theory of psychosocial development states that during adolescence, individuals face the conflict of identity vs. role confusion. If this conflict is resolved negatively, adolescents experience role confusion. Role confusion occurs when adolescents fail to develop a clear sense of identity, leading to uncertainty about their future roles. Choices A, B, and C are incorrect because they correspond to earlier stages of Erikson's stages of psychosocial development (mistrust corresponds to infancy, isolation to early adulthood, and inferiority to middle childhood), not adolescence.
