1. The two main types of designs used in all research on human behavior are __________ and __________.
- A. observational; experimental
- B. correlational; experimental
- C. observational; correlational
- D. variable; observational Answer: B Page Ref: 31 Skill Level: Remember and limitations of each. Topic: Studying Development Difficulty Level: Easy
Correct answer: B
Rationale: The two main types of designs used in all research on human behavior are correlational and experimental. Correlational research examines the relationship between two or more variables without establishing causation, while experimental research involves manipulating one variable to observe the effect on another variable. These two types of designs are fundamental in understanding and studying human behavior.
2. It is difficult to isolate the precise damage caused by illegal drugs during pregnancy because __________.
- A. most drug-using mothers refuse to participate in teratology research
- B. the majority of babies born to drug-using mothers do not survive for more than a few days
- C. most drug-using mothers quit using illegal drugs during the first trimester of pregnancy
- D. drug users often take several drugs, display other high-risk behaviors, and suffer from other stresses
Correct answer: D
Rationale: The difficulty in isolating the precise damage caused by illegal drugs during pregnancy is due to the fact that drug users often take several drugs, display other high-risk behaviors, and suffer from other stresses. This makes it challenging to identify the specific impact of each individual factor on prenatal development. Choices A, B, and C are incorrect because they do not address the complexity of the situation involving drug users during pregnancy. Most drug-using mothers refusing to participate in teratology research, the majority of babies not surviving, or drug-using mothers quitting during the first trimester do not directly explain the difficulty in isolating the precise damage caused by illegal drugs during pregnancy.
3. Katie wonders when she will first be able to hear her fetus's heartbeat through a stethoscope. You tell her that this should happen by the __________.
- A. fourth week of pregnancy
- B. third month of pregnancy
- C. end of the second trimester
- D. beginning of the third trimester
Correct answer: B
Rationale: The correct answer is the third month of pregnancy (choice B). During the third month of pregnancy, which is around 9-12 weeks, a fetal heartbeat can typically be heard using a stethoscope. This is an exciting milestone for expectant parents as it provides reassurance about the baby's well-being. Choices A, C, and D are incorrect because by the fourth week of pregnancy, the fetal heartbeat is not usually detectable with a stethoscope. The end of the second trimester and the beginning of the third trimester are too late in the pregnancy timeline for this milestone.
4. According to the cognitive perspective of perceptual development, what do babies do?
- A. are blank slates
- B. impose meaning on what they perceive
- C. actively search for discontinuous stimuli
- D. seek variant features in the environment
Correct answer: B
Rationale: According to the cognitive perspective of perceptual development, babies impose meaning on what they perceive. This means that babies actively interpret and make sense of the stimuli they encounter. Choice A is incorrect because babies are not seen as blank slates in this context; they actively engage with their environment. Choice C is incorrect as babies do not necessarily search for discontinuous stimuli, but rather interpret what they perceive. Choice D is incorrect as seeking variant features in the environment is not a core concept of the cognitive perspective of perceptual development.
5. Dr. Redmund characterizes his view of development as a bioecological model. His perspective is aligned with that of which theorist?
- A. Jean Piaget
- B. Urie Bronfenbrenner
- C. Lev Vygotsky
- D. Niko Tinbergen
Correct answer: B
Rationale: Dr. Redmund's view of development aligns with the bioecological model, which is associated with Urie Bronfenbrenner. This model emphasizes the interaction between an individual's biological characteristics and environmental influences in development. Jean Piaget's theory focuses on cognitive development, Lev Vygotsky's theory emphasizes social interactions, and Niko Tinbergen is known for his work in animal behavior and instinct, not human development. Therefore, the correct answer is Urie Bronfenbrenner (Choice B).
