A researcher who studies language development and tracks the rate at which toddlers learn new words is interested in which domain of human development?

Early adulthood

An author on a new book tour markets the book with messages such as, "Do you constantly think about your love life and work? Are you deciding if you'll get married and have children? Are you in the process of finishing up your formal education and launching your career? Are you still struggling to feel like an adult? Then this book is for you." This author is marketing to people in which period of human development?

development is plastic

An elderly person is experiencing age-related memory decline. A healthcare provider recommends brain training programs based on research indicating that dimensions of cognitive decline are partially reversible because the brain retains a lifelong capacity to reorganize cortical tissue. This healthcare provider's recommendation is aligned with which of Baltes' key principles of lifespan development?

In a study of children, let's suppose that researchers found a positive correlation (r= .63) between creativity and resilience. How is this finding interpreted?

Children who score higher on measures of creativity also score higher on measures of resilience. (a negitive correlation would occur when the two variables move in opposite directions: higher creativity is associated with lower resilience.

A graduate student research team is giving an oral presentation of their research on resilience in young adults. They note that a downside of their study is that participants were recruited from the university that they attend. What makes this a study limitation?

College students are samples of convenience that are not randomly selected from the wider population and may not represent all young adults in our society.

In a health class for middle schoolers, the instructor discusses puberty, to the embarrassment of the students, and reviews the biological factors involved in how their bodies are changing, the cognitive factors involved in more advanced thinking skills, the emotional factors involved in regulating feelings, and the social factors involved in navigating relationships.

Development is multidimensional.

development is lifelong

Motivational quotes that inspire people to keep learning and growing, no matter how young or old, are aligned with Baltes' key principles of lifespan development that

In a study of empathy across young adulthood to older adulthood, researchers found a negative correlation (r= -.75) between empathy and age. How is this finding interpreted?

Older adults tended to have lower empathy scores than younger adults.

discontinuous development

Parents exclaim, "One day my baby was crawling around on the floor, and the next day my toddler was wobbling around the house on two feet! It all happened so suddenly." Which approach to describing how developmental changes occur does the parents' statement reflect?

to test whether a relationship exists between 2 or more variables

Petersen uses a correlational study to determine if time spent playing video games is related to obesity. The objective of this research is ________.

socioeconomic status

Researchers are implementing educational intervention programs designed to reduce and eliminate the academic achievement gap across racial/ethnic groups. Many of these programs target the development of academic skills in children from low-income families, given that family education, income, and occupation strongly influence the academic achievement gap.

DeShawn has a hunch that people eat more pizza during football season. He and his friends want to test this theory, so they ask everyone they know about their pizza consumption and determine that, yes, pizza consumption does increase during the fall. DeShawn first wrote down his hypothesis, then surveyed his friends, and drew conclusions. DeShawn's research is

biased because he only asked his friends and family.

normative age-graded influences

biological and environmental factors that have a strong correlation with chronological age

culture

blueprint or guideline shared by a group of people that specifies how to live; passed down from generation to generation; learned from parents and others

Using the scientific method, researchers should

build upon earlier research to enhance understanding of a topic.

A researcher conducted an in-depth study of a child who was raised in isolation and had no contact with same-age peers until age 10. This researcher detailed the child's development in a number of spheres: physical/motor, language/cognitive, social and emotional. What kind of research method is this?

case study

The results of an experiment on the effects of sleep training on sleep quality showed that participants who received eight sessions of sleep enhancement training had longer sleep duration and better sleep quality than participants who did not receive the training. This led the researchers to conclude that an eight-week sleep enhancement training program is effective for improving sleep quality. What advantage of experimental research does this demonstrate?

cause and effect relationships

Parents track the number of new words their toddler learns each day and are surprised by how many new words their child has learned at the end of one month. By charting their child's language development, these parents are showing an interest in the ________ of human development.

A research team designed a study of parenting style that included three groups: parents in their 30s with preschool-age children (2-5), parents in their 40s with children ages 6-11, and parents in their 50s with adolescents ages 12-18. This design is considered by the researchers to be less-time consuming and expensive than other potential designs, but they acknowledge the limitation of having only one measurement of parenting style for one point in time. As such, they cannot conclude that changes between parent groups indicate changes with age over time. Which research design does this describe?

cross sectional study

Researchers wanted to study alcohol use by teenagers and observe if there were any differences between cohorts over time. They compared three groups of students (grades 6 to 8, grades 9 to 10, and grades 11 to 12) and focused on the frequency and amount of their alcohol use over a five-year period. They collected useful information about age-related changes, changes within the same individuals as they aged, and were able to account for the possibility of cohort and/or time of measurement effects. This is an example of

cross sectional study

Development can follow a different course for each child.

A teenager bemoans, "My life is a roller coaster. I've got all this new stuff to think about and I'm not as good at things I used to do well. I think I'm making progress in one area, but I'm losing ground in another." This statement about alternating between gains and losses reflects which of Baltes' key principles of lifespan development?

Development is multidirectional. (alternating between gains (growth) and losses (decline)

Researchers conducted an experiment to study the effects of sleep training on sleep duration and quality. They randomly assigned some participants to a treatment condition where they received eight sessions of sleep enhancement training and some participants to a control condition where they did not receive the training.

When scientists use this database to study the various factors that influence adolescent brain, cognitive, social, and emotional development, what type of research method are they doing?

Researchers build upon each other's work by following up on suggested directions for future research and addressing limitations of previous studies. For example, a researcher might extend a study that was originally conducted with an urban sample to include people living in suburban and rural areas. Which aspect of the scientific method does this demonstrate?

The scientific method facilitates the establishment of a literature or knowledge base.

When researchers select participants for their studies in a random way to ensure that all members have an equal chance of being selected, they are demonstrating which aspect of the scientific method?

The scientific method offers a systematic way to make comparisons and guard against bias.

The dependent variable is the outcome or the factor affected by the introduction of the independent variable. In this case, the dependent variable, or outcome of interest, is depression.

A team of researchers is interested in studying changes in parenting style over time, as children and parents grow older. One researcher states, "If we choose a ________, then it would be less time consuming and expensive. Another researcher comments, "If we choose that design, then we have measurements of parenting style for one point in time, and we can't be sure about changes with age over time."

cross-sectional research design

Thompson uses observation and surveys to study how much time children spend playing outside. The objective of this research is to

describe the occurrence of time being spent playing outside. (Observation and surveys are used in descriptive studies to describe a phenomenon.)
