What This Document Is
This document provides a foundational overview of scientific research principles, specifically tailored for students in Human Factors Engineering (HFE). It explores the critical role of rigorous research methodologies in the development and evaluation of user-centered designs. The material delves into the core tenets of the scientific method and its application to understanding human behavior in relation to systems and technologies. It’s designed to build a strong understanding of *why* research is essential in the field, rather than simply *how* to conduct it.
Why This Document Matters
This resource is invaluable for students in HFE 734, and anyone seeking to understand the basis for evidence-based design. It’s particularly helpful when beginning research projects, evaluating existing studies, or needing to justify design decisions with scientific reasoning. Understanding these principles will empower you to critically assess information and contribute meaningfully to the field. It’s best utilized early in the course, as a building block for more advanced research methods training.
Common Limitations or Challenges
This document focuses on the *principles* underlying scientific research. It does not provide detailed, step-by-step instructions for conducting specific research studies, performing statistical analyses, or writing research reports. It also doesn’t cover specific research designs (e.g., within-subjects, between-subjects) or data collection techniques. Think of this as the “why” behind the research, not the “how.”
What This Document Provides
* An exploration of the importance of scientific research in Human Factors Engineering.
* Discussion of common pitfalls in relying on intuition and the need for empirical evidence.
* Key characteristics of the scientific method, including empiricism and skepticism.
* An overview of the elements of scientific inquiry and the importance of replication and peer review.
* A breakdown of the goals of scientific research, including description, prediction, explanation, and determining causation.
* Examination of the necessary conditions for establishing causation.
* Distinction between basic and applied research within the context of HFE.
