Types of research designs What kinds of research questions are you investigating? • E.g., Cause and effect? Descriptive? Conducting Research Observational approaches: Data collection How do we observe the behaviors of interest? • • • • • Naturalistic observation Direct Observation Participant observation Survey & interviews Archival data Systematic (contrived) observation • Experiments Observational Methods Observation without manipulation Systematic (Contrived Observation): The observer sets up the situation that is observed Observations of one or more specific variables made in a precisely defined setting Much less global than naturalistic observations Often takes less time However, since it isn’t a natural setting, the behavior may be changed Observational Methods Observational approaches: Data collection How do we observe the behaviors of interest? Types of research designs What kinds of research questions are you investigating? • E.g., Cause and effect? Descriptive? Conducting Research Case studies Correlational Intensive study of a small set of individuals and their behaviors Looking for a co-occurrence relationship between two (or more) variables Experimental Investigating the cause-and-effect relationship between two (or more) variables through the manipulation of variables Quasi-experimental • Experimental designs with one or more non-random variables Types of research designs Intensive study of a single person, a very traditional method. Typically: Descriptive (and non-experimental). Interesting (and often rare) case. Fits well with clinical work. Phineas Gage (Sci. Am. Show) Sept 13, 1848 Explosion propelled a railroad tamping rod through his brain Changed personality This view has some disadvantages There may be poor generalizabilty There are typically a number of possible confounds and alternative explanations Case Histories See: Oliver Sacks’ books for some other great examples interview Measure two (or more) variables for each individual and see if the variables co-occur (suggesting that they are related) ? or Used for: or Predictions Establishing Reliability and Validity Evaluating theories Limitation: Shouldn’t make casual claims Correlational Methods We’d like to say: To be able to do this: causes There must be co-variation between the two variables The causal variable must come first or Directionality problem • Happy people sleep well • Or is it that sleeping well when you are happy? Need to eliminate plausible alternative explanations Third variable problem • Do Storks bring babies? • Neyman (1952) reported a strong positive correlation between number of babies and stork sightings Causal claims Source: Kronmal (1993) r = 0.63 • Do Storks bring babies? • Neyman (1952) reported a strong positive correlation between number of babies and stork sightings Causal claims • Is killing storks and effective method of controlling birth rates? Theory 1: Storks deliver babies Theory 2: Underlying third variable Manipulating and controlling variables in laboratory experiments Must have a comparison At least two groups (often more) that get compared One groups serves as a control for the other group Variables Independent variable - the variable that is manipulated • Allows for the testing of causal hypotheses Dependent variable - the variable that is measured Control variables - held constant for all participants in the experiment The experimental method Manipulating and controlling variables in laboratory experiments Advantages Precise control possible Precise measurement possible Theory testing possible Can make causal claims Disadvantages Artificial situations may restrict generalization to “real world” Complex behaviors may be difficult to measure The experimental method The Literature Why review it? What is it? How do you read it? How do you write it? Reading and Writing with Style (APA) What are the goals of a research article? For the reader to: Know about the research Understand what was done Allow further testing & replication Be convinced by the research (hopefully) Standardization of research report format APA style Organization and content reflects the logical thinking in scientific investigation Standardization helps with clarity Read with a critical eye Write with clarity in mind Reading a research article Writing the paper is the routine part of the research process Just the facts Forces you to commit to your evidence and conclusions The facts are just part of the argument that the author is making What you say is all that is important, how you say it isn’t important Good writing leads to higher chance of accomplishing your goals Misconceptions about Scientific writing Psychological writing tends to differ from other academic writings • Not a creative writing exercise • Presenting an argument based on data and logical reasoning • Try to avoid using direct quotes, restate things in your own words. • Avoid digression • Footnotes are rare, they’re used to elaborate/clarify a point. Try to do so in the text. • If long digressions, use the appendix Writing style The ultimate resource for APA style is the APA Publication manual 6th ed. Chapter 8 of your textbook is good too. Lab manual sample paper pp 86-93 Also websites to help too. Writing resources A great book for Psychological writing Sternberg, R. J. (2003). The psychologist’s companion: A guide to scientific writing for students and researchers. Cambridge University Press, NY. Writing resources To ease communication of what was done Forces a minimal amount of information Provides a logical framework (for argument) Provides consistent format within a discipline • People know what to expect • Where to find the information in the article Allows readers to cross-reference your sources easily Why a structured format? Communicate with clarity Major goal: Clarity Communicate with clarity Major goal: Clarity Communicate with clarity Write for the reader • Think about your audience, what do they already know, what don’t they know Avoid overstatements • Be conservative in your claims Emphasize the positive • Focus on how the data supports a theory not just on how it refutes another theory Major goal: Clarity Communicate with clarity Avoid • Jargon when possible • Slang and colloquialisms • Sexist and biased language Try to be concise • • • • Don’t use a whole paragraph when two sentences will do Longer papers don’t mean better papers Eliminate unnecessary redundancy Use simple words (sentences) rather than complicated words (sentences) Major goal: Clarity Communicate with clarity Use concrete words and examples Check your work! • Read it over, make sure that you say what you mean to say Use a consistent format (APA style) • It helps your reader understand your arguments and the sources they’re built on. • It also helps you keep track of your sources as you build arguments Major goal: Clarity • Title Page • • • • • • • • Abstract Body References Authors Notes Footnotes Tables Figure Captions Figures Adolescent AdolescentDepression Depression1 2 Running Head: ADOLESCENT DEPRESSION We explored attachment in a family context by applying family systems principles to the investigation of multiple attachment relationships within families.

APA style: Parts of a research report The basic parts of a research article: Title and authors - gives you a general idea of the topic and specifically who did it Abstract - short summary of the article The anatomy of a research article Running head – will go on each page of published article, no more than 50 characters Running Head: ADOLESCENT DEPRESSION 1 Title should be maximally informative while short (10 to 12 words recommended) Order of Authorship sometimes carries meaning Adolescent Depression and Attachment Ima G. Student and Soyam Eye Topnotch University Affiliation – where the bulk of the research was done Title Page Published title pages will look a bit different, but you’ll find these pieces of information. Typically the body of the article will begin as well. Abstract: Short summary of entire paper • • • • • 150 to 250 words The problem/issue The method The results The major conclusions Recommendation: write this after you’ve finished the rest of the paper Good first contact, but remember that it is short on detail Shows up in PsycInfo Gets skimmed before reading the article Abstract Hourglass shape Start broad Background Literature Review Body Hourglass shape Narrow focus Statement of purpose Specific hypotheses (at least at conceptual level) Body Hourglass shape Most focused - Methods - Results Body Hourglass shape Broaden Discussion Conclusions Implications Body Introduction - gives you the background that you need Issue and Background • What is it? Why is it interesting/important? Literature Review • What has been done? What theories are out there? Statement of purpose • What are you going to do and why? Specific hypotheses (at least at conceptual level) • What do you predict will happen in your research? Body Introduction - gives you the background that you need Reading checklist 1) What is the author's goal? 2) What are the hypotheses? 3) If you had designed the study, how would YOU have done it? Writing checklist • Be cohesive • Be relevant (why are the reviewed studies relevant?) • Work on the transitions (make the flow logical) Body The basic parts of a research article : Method - tells the reader exactly what was done Enough detail that the reader could actually replicate the study. Subsections: Participants - who were the data collected from How many, where they were selected from, any special selection requirements, details about those who didn’t complete the experiment Apparatus/ Materials - what was used to conduct the study Design Suggested if you have a complex experimental design, often combined with Materials section Procedure What did each participant do? Other details, including the operational levels of your IV(s) and DV(s), counterbalancing, etc. Body The basic parts of a research article : Method - tells the reader exactly what was done Reading checklist 1 a) Is your method better than theirs? b) Does the authors method actually test the hypotheses? c) What are the independent, dependent, and control variables? 2) Based on what the authors did, what results do YOU expect? • Writing checklist • Is it clear why the procedures were selected? • Are any assumptions explicit and defended? • Is the level of detail sufficient for replication? Body Results (state the results but don’t interpret them here) Verbal statement of results Tables and figures • These get referred to in the text, but actually get put into their own sections at the end of the manuscript Statistical Outcomes • Means, standard deviations, t-tests, ANOVAs, correlations, etc. Body Results (state the results but don’t interpret them here) Reading checklist 1) Did the author get unexpected results? 2 a) How does the author interpret the results? b) How would YOU interpret the results? c) What implications would YOU draw from these results? • Writing checklist • Is it clear how the hypotheses are tested by the analyses? • Would a graph or table help clarify the results? • What questions might the reader still have, and how could I answer them in this section? Body Discussion (interpret the results) Relationship between purpose and results Theoretical (or methodological) contribution Implications Future directions (optional) Reading checklist 1 a) Does YOUR interpretation or the authors' interpretation best represent the data? b) Do you or the author draw the most sensible implications and conclusions? • Writing checklist • Have you stated your most convincing argument? • Do the conclusions follow straightforwardly from the results?
