Ethics in Research01:56

Ethics in Research

Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.
Longitudinal Research02:20

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
Archival Research01:40

Archival Research

Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...
The Scientific Method02:40

The Scientific Method

Research is what makes the difference between facts and opinions. Facts are observable realities, and opinions are personal judgments, conclusions, or attitudes that may or may not be accurate. In the scientific community, facts can be established only using evidence collected through empirical research.
Crossover Experiments01:16

Crossover Experiments

Crossover experiments, also called the repeated-measurements design, is a study design in which all experimental units are exposed to all treatments in different periods. Crossover experiments are generally used in psychology, the pharmaceutical industry, agriculture, and medicine.
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
Longitudinal Studies01:26

Longitudinal Studies

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Summary

Science and social policy influence each other, with scientific evidence increasingly informing social policy decisions. Effective communication of research findings by scientists can improve both science and social policy outcomes.

Area of Science:

  • Science policy
  • Social policy
  • Developmental science

Background:

  • Distinct cultures of science and social policy show overlapping influences.
  • Science policy is shaped by perceived social utility and problem-solving potential.
  • Evidence-based policy mandates increase social policymakers' use of scientific information.

Purpose of the Study:

  • To examine the interplay between science policy and social policy.
  • To highlight the role of scientific evidence in policy consensus.
  • To provide recommendations for developmental scientists to improve policy impact.

Main Methods:

  • Analysis of the relationship between scientific evidence and policy development.
  • Case study of early childhood intervention programs.

  • Discussion of factors influencing policy decisions.
  • Main Results:

    • Scientific evidence, particularly strong and cumulative, can drive policy consensus, as seen in early childhood interventions.
    • Social policy incorporates scientific information alongside ideology, interests, and institutional factors.
    • Overlapping influences exist between science policy and social policy.

    Conclusions:

    • Developmental scientists can enhance policy by improving research quality and communication.
    • Effective translation of research into policy is crucial for addressing social problems.
    • Strengthening the scientific basis of policy leads to better societal outcomes.
