       Three types of articles
• Reports of empirical studies

• Literature reviews/meta-analyses
  – Statistical reviewing procedure that uses data
    from many similar studies to summarize and
    quantify research findings about individual

• 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

     Introduction: Hypotheses
• Some studies test hypotheses

• Some studies do not have hypotheses

  – Researchers did not know what to expect

• Presented at the end of the intro

• Accompanied by a rationale
 Group Questions: Introduction

• Does the research question/hypothesis
  follow logically from the literature review?

  was it operationally defined?

• What was the independent variable and
  how was it operationally defined?
• Describe statistical analysis
  – Evaluate – correct?

• Present tables and figures
  – Evaluate – correct?

• Findings clearly presented?
    Group Questions: Results
• What were the overall findings?

• Were the study finding clearly presented?

• Can the results be used to answer the
  research question?
• 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 could these be answered?
• General implications
• Benefits to society
• Use of results outside psychology

• As a reviewer – you must pull together
