Human Growth and Development Final Exam

1. Theorists who contend that powerful negative events in the first few years cannot be fully overcome by later, more positive ones emphasize __________.

A. plasticity
B. stability
C. nurture
D. discontinuity

Correct answer: B

Rationale: Theorists who emphasize stability argue that powerful negative events early in life cannot be completely overcome by later, more positive experiences. They believe that early experiences have a lasting impact on development and are not easily erased or reversed by subsequent events. This perspective contrasts with the idea of plasticity, which suggests that development can be influenced by experiences at any point in life, and that individuals have the capacity for change and growth throughout the lifespan. 'Nurture' does not directly address the concept of overcoming negative events, while 'discontinuity' refers to developmental stages being separate and distinct, not the idea that negative events early in life persist despite later positive experiences.

2. By the twelfth week of pregnancy, __________.

A. the sex of the fetus can be detected with ultrasound
B. the mother can feel the movements of the fetus
C. the fetus is viable and can survive if born early
D. synchrony between fetal heart rate and motor activity peaks Answer: A Page Ref: 79 Skill Level: Understand Copyright Ã‚Â© 2018 Laura E. Berk. All Rights Reserved. 6 Test Bank for Berk, Development Through the Lifespan, 7e Topic: Prenatal Development Difficulty Level: Moderate

Correct answer: A

Rationale: By the twelfth week of pregnancy, the sex of the fetus can be detected with ultrasound. Ultrasound technology allows for visualization of the developing fetus and identification of physical characteristics, such as sex, during prenatal appointments.

3. G. Stanley Hall and his student, Arnold Gesell, __________.

A. discovered that prenatal growth is strikingly similar in many species
B. launched the normative approach
C. constructed the first standardized intelligence test
D. were the forefathers of psychoanalytic theory

Correct answer: B

Rationale: G. Stanley Hall and his student, Arnold Gesell, launched the normative approach. This approach involves studying large numbers of people of different ages and examining the age-related averages of behaviors to establish norms or typical development patterns. These scholars focused on the systematic observation of how and when certain behaviors appear in children. Choices A, C, and D are incorrect because they do not accurately reflect the contributions of G. Stanley Hall and Arnold Gesell in the field of developmental psychology.

4. What did Ivan Pavlov discover?

A. observational learning
B. classical conditioning
C. the ego's positive contributions to development
D. the clinical method

Correct answer: B

Rationale: Ivan Pavlov discovered classical conditioning. This is a form of learning in which a neutral stimulus becomes associated with a meaningful stimulus and acquires the capacity to elicit a similar response. Pavlov's famous experiment with dogs, where he conditioned them to salivate at the sound of a bell, demonstrated this principle. Choices A, C, and D are incorrect because Pavlov's work primarily focused on classical conditioning, not observational learning, ego contributions to development, or the clinical method.

5. Currently, the most widely used potent teratogen is __________.

A. aspirin
B. diethylstilbestrol (DES)
C. thalidomide
D. isotretinoin

Correct answer: D

Rationale: The correct answer is D, isotretinoin. Isotretinoin is a medication commonly used to treat severe acne, but it is a potent teratogen, meaning it can cause severe birth defects if taken during pregnancy. Aspirin (choice A) is not a widely used potent teratogen. Diethylstilbestrol (DES) (choice B) was a known teratogen, but it is not currently widely used. Thalidomide (choice C) was another historical teratogen, but it is also not currently widely used. Therefore, isotretinoin is the most relevant answer as it is a commonly used medication that poses a high risk of birth defects if used during pregnancy.
