1. Shamona, a pregnant mother in Flint, Michigan, is concerned about the drinking water, which shows high levels of lead. Shamona should know that high levels of prenatal lead exposure are related to __________.

• A. facial abnormalities and heart defects
• B. defects of the genitals and urinary tract
• C. low birth weight and brain damage
• D. a variety of childhood cancers

Correct answer: C

Rationale: High levels of prenatal lead exposure are related to low birth weight and brain damage. Lead exposure during pregnancy can have harmful effects on the developing fetus, leading to complications such as decreased birth weight and potential long-term brain damage. Choices A, B, and D are incorrect because they do not directly correlate with the known effects of prenatal lead exposure. While lead exposure can indeed cause a variety of health issues, such as heart defects and urinary tract problems, the primary concerns related to prenatal exposure are low birth weight and brain damage.

2. Developmental science is __________ because it has grown through the combined efforts of people from many fields of study.

• A. interdisciplinary
• B. empirical
• C. applied
• D. theoretical

Correct answer: A

Rationale: Correct answer: Developmental science is interdisciplinary because it integrates knowledge from multiple fields like psychology, biology, and sociology. The term 'empirical' refers to information gained from observation or experimentation, which is not the focus of this question. 'Applied' and 'theoretical' do not capture the essence of developmental science requiring inputs from various disciplines.

3. When faced with a problem, Sydney starts with a hypothesis, deduces testable inferences, and isolates and combines variables to see which inferences are confirmed. Sydney is in Piaget's __________ stage of development.

• A. sensorimotor
• B. preoperational
• C. concrete operational
• D. formal operational

Correct answer: D

Rationale: Sydney's approach of starting with a hypothesis, deducing testable inferences, and isolating and combining variables to confirm inferences aligns with the characteristics of the formal operational stage in Piaget's theory of cognitive development. This stage typically emerges during adolescence and is characterized by advanced logical thinking, abstract reasoning, and the ability to think systematically about all possible outcomes of a problem. Choice A, sensorimotor, is incorrect as it pertains to the stage where infants learn through sensory experiences and motor actions. Choice B, preoperational, is incorrect as it involves egocentrism and lack of conservation. Choice C, concrete operational, is incorrect as it focuses on operational thought and logical reasoning in concrete contexts.

4. 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.

5. In an experiment, the independent variable __________.

• A. is the one the investigator expects to be influenced by another variable
• B. is the one the investigator expects to cause changes in another variable
• C. cannot be manipulated or controlled by the researcher
• D. is the number that describes how two measures are associated with each other

Correct answer: B

Rationale: In an experiment, the independent variable is the one that the investigator expects to cause changes in another variable. It is the factor that is deliberately manipulated or changed by the researcher to observe its effects on the dependent variable. The purpose of manipulating the independent variable is to study its impact on the outcome, allowing researchers to establish cause-and-effect relationships in their investigations. Choice A is incorrect because the independent variable is not influenced but rather influences another variable. Choice C is incorrect as the independent variable is intentionally manipulated by the researcher. Choice D is incorrect as it refers to a different concept unrelated to the independent variable in an experiment.
