Why are clear definitions and rules important in behavioral measurement?
Press to flip
They ensure accuracy and reliability in data interpretation, leading to conclusive results.
How is the 'burden of proof' applied in psychology?
Researchers carry the burden of providing supporting evidence to substantiate their claims.
What is the role of meta-analysis in psychological research?
Meta-analysis analyzes results from multiple studies as one large study to determine the robustness and replicability of statistical effects.
How does meta-analysis contribute to understanding psychological phenomena?
By integrating data from numerous studies, meta-analysis offers a comprehensive view of the effectiveness and consistency of psychological effects.
What is essential about formulating a hypothesis in psychological research?
The hypothesis must be a clear, predictive statement that emerges from observations or general statements.
Discuss the process and importance of hypothesis testing in psychology.
Hypothesis testing involves systematic methods to validate predictions, influencing the modification or acceptance of a hypothesis.
What is the primary aim of psychological science?
To explain psychological phenomena such as thoughts, emotions, and behaviors using systematic observation and inference.
What does the principle of falsifiability imply about scientific theories?
A scientific theory must allow for scenarios that could prove it false, ensuring it is testable.
What role does 'replication' play in scientific theory evaluation?
Replication confirms the reliability of findings, demonstrating that they are consistent across different studies and observers.
What happens to a hypothesis if contradictory results are found during testing?
The hypothesis is modified to account for the new findings.
What is the importance of systematic observation in psychological science?
Systematic observation is crucial for making inferences and developing reliable theories based on empirical evidence.
How does a researcher ensure causality in an experimental study?
By using systematic methods and controlled groups to account for influencing factors.
Why is replicability a critical component in evaluating scientific theory?
Replicability ensures that the same results can be obtained by others using similar methods, which builds confidence in a finding.
How does scientific psychology differentiate itself from pseudoscience?
Through the development and evaluation of theories that provide accurate predictions, are replicable, falsifiable, and adhere to the principle of parsimony.
Explain the principle of parsimony in scientific theory development.
The principle of parsimony favors theories that make the fewest assumptions, avoiding unsubstantiated new assumptions.
