    quantify research findings about individual
    topics


• Theoretical articles
        Evaluating an Article
• How well do the study’s authors achieve
  their goal?

• Important because we rely on previous
  articles in preparing our own experiments
        Evaluating an Article
• Must ask questions relating to:
  – Purpose
  – State hypotheses
  – Design
  – Measurement strategy
  – Statistical analysis
  – Conclusions

    presented?
  – Sponsored by psychological association?
  – Peer-reviewed journal?
   Informal Discovery: Page 1
• Author: who wrote the article
  – University, agency or business affiliation
• Author’s notes
  – Funding
  – Acknowledging other contributors
  – Correspondence address
  – Results presented elsewhere
          Group Questions:
         Informal Discovery
• What do you think of the title?

• Is there anything special about the
  journal?

• What do you know about the authors?
               Abstracts
• Give overview of all main points of article
  – Study purpose
  – General research strategy
  – Findings
  – Conclusions
• Helpful in a literature search; a good
  abstract should give enough information to
  help us decide whether we want to read
  the article or not.
    Group Question: Abstract
• From the abstract – what are the
  – Purpose
  – Research strategy/design
  – Findings
  – Conclusions
 Of the study??
  Introduction: What and Why
• Overview of problem addressed
  – Clearly Stated!
• Rationale for study developed
  – Review of relevant theoretical and empirical
    literature
• Ends with a summary of research
  questions/hypotheses
      Group Questions: Intro
         What and Why
• What is the general purpose of the study?



• What problem is being studied?
 Introduction: Literature Review
• Build argument for why study is necessary
  – Origins of research question

  – Do cites provide good support for study?

  – Will this make a contribution to the field?
   Group Questions: Introduction
           Lit Review
• Review the background literature and
  answer:
  – What kind of articles are described?

  – Can you tell from the literature why the
    authors are doing the study?

  – Is the study important?
     Introduction: Hypotheses
• Some studies test hypotheses

• Some studies do not have hypotheses
  – Explicit research question/goal
  – Researchers did not know what to expect

• Presented at the end of the intro

• Accompanied by a rationale
 Group Questions: Introduction
        Hypotheses
• State the research question/hypothesis

• Does the research question/hypothesis

  – Who was studied?



  – How were they recruited?
               Procedures

      Group Questions: Method
            Procedures
• Were the procedures used appropriate?

• Would you have used this methodology?
  If not, what would you have done?

                  Results
• Describe statistical analysis
  – Evaluate – correct?

• Can the results be used to answer the
  research question?
               Discussion
• Discussion of whether hypothesis was
  supported by the data

• Point out limitations of study

• Place study in the “larger body of
  knowledge” – theoretically speaking
   Group Questions: Discussion
• What do the study findings mean for theory?

• How do the study findings build upon previous
  research?

• Are there any limitations addressed by the authors?
  Any limitations you might see?
