Question 1

Genetics is defined as ________.

Accepted Answer

Genetics is the study of inherited traits, which includes the transmission of traits from parents to offspring and the mechanisms by which traits are expressed and modified over time.

Question 2

Each of the 10 children born to Ernest and Elvira Orangeburg has been born with red hair. Each child is also very intelligent and athletic. The Orangeburgs are expecting an 11^th child, who is also likely to be born with the same traits according to ________, as evidenced in the ________.

Accepted Answer

The best answer is B because it refers to the nature versus nurture controversy, which is the debate about whether genetics (nature) or environmental factors (nurture) have a greater influence on a person's traits and characteristics. The fact that all 10 of Ernest and Elvira's children have red hair suggests that genetics play a significant role in hair color, intelligence, and athleticism, and it is likely that the 11th child will also share these traits due to their genetic inheritance.

Question 3

Which of the following is a main disadvantage of the cross-sectional design?

Accepted Answer

The main disadvantage of the cross-sectional design is that individuals of different ages are being compared to one another, which may confound results due to age-related differences rather than differences in the variable of interest. This can lead to inaccurate conclusions and limited ability to make causal inferences.

Question 4

The science of heredity is called ________.

Accepted Answer

Genetics is the study of heredity, including how traits are passed down from parents to offspring and the underlying biological mechanisms of inheritance. Human development is a broader field that encompasses the physical, cognitive, and socioemotional changes that occur throughout the lifespan. Physiology is the study of how living organisms function, while gerontology is the study of aging and its effects on individuals and society.

Question 5

Professor Grant is interested in studying the development of a sense of humor. She collects data from groups of 6-year-olds, 16-year-olds, 26-year-olds, and 46-year-olds. What type of research design is Professor Grant using?

Accepted Answer

Professor Grant is using a cross-sectional design because she is collecting data from participants of different ages at the same point in time to compare and determine differences in the development of a sense of humor among the age groups. A cohort design would involve following a group of individuals born at the same time over a period of time, a longitudinal design would involve collecting data from the same individuals over an extended period of time, and a behavior genetics design would focus on genetic and environmental factors that contribute to the development of humor.

Question 6

Professor Sanchez is interested in studying the development of motor skills. She collects data from 200, one-year-olds and follows and assesses them for a period of five years. What type of research design is Professor Sanchez using?

Accepted Answer

Professor Sanchez is using a longitudinal design as she is following and assessing the same group of individuals over time.

Question 7

Which field of study tries to determine how much of behavior is the result of genetic inheritance and how much is due to a person's experiences?

Accepted Answer

Behavioral genetics is the field of study that attempts to determine the relative contributions of genetic and environmental factors to behavior. It looks at the extent to which variations in genes contribute to differences in behavior, as well as the role of environmental factors in shaping behavior. Psychobiology and neuropsychology focus more on the biological and neural underpinnings of behavior, while psychoanalysis is a theory of personality and psychotherapy.

Question 8

A researcher who selects a sample of people of varying ages and studies them at one point in time is, by definition, using a ________ design in her study.

Accepted Answer

A cross-sectional design is used when data is collected at a single point in time, often from a sample of individuals of different ages. This type of design allows researchers to compare different age groups at the same time, but does not allow for the examination of individual change over time.

Question 9

Juan and Carlos are identical twins. Juan was raised by his father and mother, and Carlos was accidentally placed with another family after a "mix up" at the hospital. At the age of 15, both boys "ran into each other" at a football game and noticed how they appeared to be "mirror images of each other." After proving they were twins by genetic testing, the families discussed some of the differences between the boys. Juan is very athletic and intelligent and excels in basketball but does not take school seriously and has F's in all subjects. Carlos is also athletic and intelligent, and excels in baseball and makes straight A's as a result of his strict home life and study routine. Although they are identical twins, what do you think accounts for the differences in their academic performance based on the research?

Accepted Answer

The differences in Juan and Carlos' academic performance can be attributed to nurture, or the environment they were raised in. Juan's lack of success in school may be a result of a less strict or supportive home life, while Carlos' consistent success may be due to the strict routine and supportive environment provided by his adoptive parents. While nature (genetics) certainly plays a role in their athletic and intellectual abilities, it cannot fully account for their differing academic performance. The school district superintendent and teacher appraisals may also play a role in their academic success, but they are external factors that cannot fully explain the differences between Juan and Carlos.

Question 10

The local health department of a small town has hired a research firm to study the development of cancer in residents in the town due to a suspected cancer-causing agent and environmental pollution. The researcher will compare data on participants every 10 years (e.g., at ages 10, 20, 30, etc.) to see if there are increasing rates of cancer in the town. This type of research study is called a ________ design.

Accepted Answer

A longitudinal design involves following a group of participants over an extended period of time, in this case, every 10 years. This allows for the researcher to see if there are changes or trends in the development of cancer in the town. A cross-sectional design would involve comparing different age groups at one point in time, which would not provide information on changes over time. A cross-sequential design combines both longitudinal and cross-sectional designs by following multiple age groups over time, but this is not specified in the scenario. Behavior genetics is a field of study focused on the genetic and environmental influences on behavior, not specific research designs.

Question 11

Smith believes people who are very aggressive have become so because of their life experiences. Dr. Goldberg believes people are more or less aggressive from birth because of genetic factors. Which of the following terms BEST describes an issue in human development that is highlighted by their disagreement?

Accepted Answer

Smith and Dr. Goldberg's disagreement centers around the issue of whether aggression is primarily determined by environmental or genetic factors. This is a classic example of the nature versus nurture debate in human development.

Question 12

Unlike other types of research, a cross-sequential design allows researchers to ________.

Accepted Answer

A cross-sequential design combines elements of longitudinal and cross-sectional research strategies by following different age cohorts over a span of time. This allows researchers to explore changes, continuity, and individual differences in development. Gender differences or experimenter bias may also be addressed within this design, but they are not unique features of it. Option D is incorrect because a cross-sequential design includes both longitudinal and cross-sectional strategies.

Question 13

Professor Rashad is interested in studying cognitive development. He collects and compares data from a group of 6-year-olds and a group of 10-year-olds. Five years later, he compares these two groups to each other again as well as to their own performance in the study five years ago. Professor Grant is employing a ________ design in his research.

Accepted Answer

This design combines both cross-sectional and longitudinal designs, as it involves testing different age groups at the same time and then following them up over a period of time. In this case, Professor Rashad is comparing 6-year-olds and 10-year-olds, and then testing them again five years later. This allows for the investigation of both age effects and cohort effects.

Question 14

Which of the following is a disadvantage of the longitudinal design?

Accepted Answer

Participants may drop out due to moving, loss of interest, or death. This can lead to reduced sample sizes and potentially biased data if those who drop out have different characteristics compared to those who remain in the study.

Question 15

________ refers to heredity and ________ refers to environmental influences.

Accepted Answer

The terms "nature" and "nurture" are commonly used to refer to the debate over the relative contributions of genetics (nature) and environment (nurture) to human development and behavior. Cognition and emotion are not directly related to this debate, while "cross-sectional" and "longitudinal" refer to types of research methods, not concepts of development.

Question 16

A psychologist spends her entire career studying how and why changes occur in people throughout their lives. This psychologist is most likely working in the field of ________.

Accepted Answer

The field of human development focuses on understanding the processes of change and stability throughout the life cycle. This includes physical, cognitive, emotional, and social development.

Question 17

The type of research design that compares various participants at several points in time to examine age-related differences and changes is called a ________.

Accepted Answer

A cross-sequential design involves a combination of cross-sectional and longitudinal designs, where researchers compare different age groups at multiple points in time. This allows for the examination of both age-related differences and changes over time. A longitudinal design only follows one group of participants over time, while a cross-sectional design only compares different age groups at one point in time. A behavior genetics design focuses on genetic and environmental influences on behavior rather than age-related differences and changes.

Question 18

According to several published research studies, how could individuals like Adolf Hitler or Boston Marathon bomber Dzhokhar Tsarnaev commit such acts according to the "nature versus nurture" debate?

Accepted Answer

The most widely accepted explanation for the behavior of individuals like Adolf Hitler or Boston Marathon bomber Dzhokhar Tsarnaev is a combination of both nature and nurture. While genetic factors may play a role in certain behaviors, environmental influences such as upbringing, socialization, and cultural factors are also important. Some research suggests that traumatic experiences, social exclusion, and radicalization may contribute to the development of extremist ideologies and violent behaviors. Therefore, it is likely that both genetic and environmental factors interact to produce these extreme behaviors.

Question 19

In a ________ design, one group of participants is followed and assessed as the group ages.

Accepted Answer

A longitudinal design is used to track and study a single group of participants over an extended period, usually years or even decades. This approach is especially useful for examining changes in behavior or development over time, and for identifying individual variations in patterns of change. Cohort, behavior genetics, and cross-sectional designs all refer to different types of research methods that may involve studying multiple groups of participants at once, rather than following a single group over time.

Question 20

The scientific study of the changes that occur in people as they age from conception to death is called ________.

Accepted Answer

Human development is the scientific study of the changes that occur in people as they age from conception to death.
