1. Dr. George predicted that positive reinforcement would increase prosocial behavior in preschoolers. Dr. George's prediction is an example of a __________.
- A. theory
- B. research question
- C. hypothesis
- D. research design
Correct answer: C
Rationale: Dr. George's prediction that positive reinforcement would increase prosocial behavior in preschoolers is an example of a hypothesis. A hypothesis is a specific, testable prediction about the relationship between variables based on existing knowledge or theories. In this case, Dr. George is making a prediction about the effect of positive reinforcement on prosocial behavior, which can be tested through research. Choice A, 'theory,' is incorrect because a theory is a broader explanation that integrates a range of findings and observations. Choice B, 'research question,' is incorrect as it refers to an inquiry that asks about the relationship between variables but lacks the specificity and testability of a hypothesis. Choice D, 'research design,' is incorrect as it pertains to the overall strategy or plan for conducting a research study, not the specific prediction Dr. George made.
2. Dr. Anodyne found a correlation of +.49 between illegal drug use and levels of adolescent delinquency. This correlation is __________ and __________.
- A. moderate; positive
- B. low; positive
- C. high; negative
- D. low; negative Answer: A Page Ref: 33 Skill Level: Apply and limitations of each. Topic: Studying Development Difficulty Level: Easy
Correct answer: A
Rationale: The correlation of +.49 indicates a moderate strength of relationship between illegal drug use and levels of adolescent delinquency. The positive correlation indicates that as one variable (illegal drug use) increases, the other variable (adolescent delinquency) also tends to increase.
3. People born during the baby boom between 1946 and 1964 tend to be alike in ways that set them apart from people born at other times due to __________ influences.
- A. age-graded
- B. history-graded
- C. nonnormative
- D. bio-historical Answer: B Page Ref: 9‒10 Skill Level: Remember Topic: The Lifespan Perspective: A Balanced Point of View Difficulty Level: Easy
Correct answer: B
Rationale: People born during the baby boom between 1946 and 1964 tend to be alike in ways that set them apart from people born at other times due to history-graded influences. These influences refer to the events and conditions that are common to a particular historical era and can significantly shape the development and experiences of individuals who live through them. The post-World War II era, economic prosperity, and social changes during the baby boom period are examples of historical events that have had a lasting impact on this generation.
4. In egalitarian marriages, __________.
- A. there is a clear division of roles
- B. partners share power and authority
- C. the husband is the head of the household
- D. the wife is responsible for family economic well-being
Correct answer: B
Rationale: In egalitarian marriages, the correct answer is B - partners share power and authority. This type of marriage promotes equality and balance, where both spouses have an equal say in decision-making and share responsibilities. Choice A is incorrect because egalitarian marriages aim to reduce traditional role divisions. Choice C is incorrect as it suggests a patriarchal structure, which is contrary to the principles of egalitarianism. Choice D is incorrect as it assigns a specific financial role based on gender, which goes against the idea of equal sharing in all aspects of the marriage.
5. Recent evidence suggests that paternal alcohol use around the time of conception __________.
- A. can alter gene expression
- B. can cause fetal alcohol syndrome
- C. is linked to blood vessel abnormalities
- D. has no negative effect on the developing organism
Correct answer: A
Rationale: Recent evidence suggests that paternal alcohol use around the time of conception can alter gene expression. This means that paternal alcohol consumption can potentially impact the genes and genetic materials passed on to offspring, affecting their development and health. Choice B is incorrect because fetal alcohol syndrome is typically associated with maternal alcohol consumption during pregnancy, not paternal alcohol use around conception. Choice C is incorrect as there is no direct link between paternal alcohol use and blood vessel abnormalities. Choice D is incorrect as paternal alcohol use can indeed have negative effects on the developing organism, particularly through altering gene expression.
