The Simple Life: Graphs to aid understanding of the results
In my first publication, my advisor and I created graphs according to the guidelines listed on the Judgment and Decision Making journal's webpage. My advisor and I both maintain a general preference to see results presented visually, in the form of easily-understood, properly-labeled graphs. However, in correspondence with JDM's editor, he felt that the results were simple enough to understand, and the graphs therefore weren't really necessary.
I think the editor's idea was that:
a) not including the graphs would save space, and
b) including the graphs would probably involve a bunch of difficult/time-consuming formatting. I certainly don't blame the editor for advising us to exclude the graphs; I understand perfectly where he's coming from!
So, to save time, space, and effort, our graphs were never published. Until now.
The graph for Experiment 1, which fits best with the information presented near the top of p. 305, presents the proportion of participants' decisions that were consistent with pre-exposure (bar on left) and with the recognition heuristic (as determined by participants' self-reported recognition; bar on right). Error bars represent 95% confidence intervals.
The graph for Experiment 2, below, illustrates the data presented on p. 307-308. The dots represent the mean proportion of choices that were consistent with the recognition heuristic, for participants in each of the three training conditions. Again, error bars indicate 95% confidence intervals, which I recommend reporting as part of a more complete picture of your data.
Here's a link to the full-size .jpg image for the first graph, and here's the link for the second graph.
