Chapter 2: Research Methods in I/O Psychology Research a formal process by which knowledge is produced and understood Generalizability the extent to which conclusions drawn from one research study spread or apply to a larger population 3 goals of science: description, prediction, explanation The Empirical Research Process Steps in conducting empirical research: 1. Statement of the problems 2. Design of research study 3. Measurement of variables 4. Analysis of data 5. Conclusions from research And back to #1. This is an important feedback factor: results from step five influence the first step in future studies Statement of the Problem Theory a statement that proposes to explain relationships among phenomena of interest Inductive method a research process in which conclusions are drawn about a general class of objects or people based on knowledge of a specific member of the class under investigation After conducting research on a topic, researchers may propose a theory about why the behavior occurs Deductive method a research process in which conclusions are drawn about a specific member of a class of objects or people based on knowledge of the general class under investigation Here, the researcher forms a theory first and then tests the theory by collecting data Accurate theory: data will support it; inaccurate theory: data will not support it Psychology is difficult to investigate people are far too variable Lewin a theory is useful for conducting research; it synthesizes info, organizes it into logical components, and directs the researcher’s efforts in future studies Skinner too much effort is spent on “proving” theories; productive research doesn’t require a theory extreme empiricism Chan researchers become too committed to proving their theories and become blinded to info that doesn’t conform to the theory they want to believe A theory is an important way to specify research questions, but it is only one of many ways to formulate a research problem Design of the Research Study Research design a plan for conducting scientific research for the purpose of learning about a phenomenon of interest Research strategies may be compared on these two important dimensions: 1. The naturalness of the research setting 2. The investigator’s degree of control over the study Internal validity the degree to which the relationships evidenced among variables in a particular research study are accurate or true o The extent to which the results are attributed to the variables investigated rather than to other possible explanations External validity the degree to which the relationships evidenced among variables in a particular research study are generalizable or accurate in other contexts o The extent to which findings from a study are relevant to individuals and settings beyond those specifically examined o

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
