Chapter 2: Research in Child Development 2.1 Doing Child-Development Research 2.2 Child-Development Research and Family Policy

2.1 Doing Child Development Research Measurement in Child- Development Research General Designs for Research Designs for Studying Development

Measurement in Child- Development Research Systematic Observation: naturalistic observation and structured observation Sampling behavior with tasks Self reports include questionnaires and interviews 2.1 Doing Child-Development Research

Measurement in Child- Development Research Measures should be both valid and reliable Samples of children who participate in research should be representative of the population of interest 2.1 Doing Child-Development Research

General Designs for Research Correlational studies look at relations as they exist in the real world These real-world relations are expressed as a correlation coefficient, r, that ranges from -1 to Doing Developmental Research

Three Interpretations of a Correlation Coefficient

General Designs for Research Experiments involve manipulating key factors that an investigator thinks are important The manipulated factor is the independent variable; the behavior measured is the dependent variable In field experiments, the researcher manipulates independent variables in a natural setting 2.1 Doing Developmental Research

Example of an Experiment

Designs for Studying Development Longitudinal study: the same individuals are tested repeatedly Microgenetic study: children are tested repeatedly over a span of days or weeks Cross-sectional study: children of different ages are tested 2.1 Doing Developmental Research

Comparison of Longitudinal and Cross-Sectional Studies Longitudinal DesignCross-Sectional Design

Ethical Responsibilities Minimize risks to research participants Describe the research to potential participants Avoid deceiving the participants Keep results anonymous or confidential 2.1 Doing Child-Development Research

Communicating Research Results Research results are reported in scientific journals Results of individual studies will be reported in the Focus on Research features Converging evidence from many studies is necessary 2.1 Doing Child-Development Research

2.2 Child Development Research and Family Policy Background Ways to Influence Social Policy An Emphasis on Policy Implications Improves Research

Background Results of child-development research can improve children’s lives Research can help changing families decide what is best for their children Research can help children who face hurdles to healthy development 2.2 Child-Development Research and Family Policy

Ways to Influence Social Policy Build understanding of children’s development Be advocates for children Evaluate policies and programs Develop a model program 2.2 Child-Development Research and Family Policy

An Emphasis on Policy Implications Improves Research Focusing on policy implications leads to improved theory and research Concern with family policy has improved research methods 2.2 Child-Development Research and Family Policy
