Washington, DC: Author vii viii P R E FA C E conducted electronically; researchers can easily draw and subsequently print their figures for reports and theses using personal computers and printers Some APA Style guidelines have changed (the previous edition of Displaying Your Findings was based on the 5th ed of the Publication Manual) Furthermore, some reporting standards for statistics have changed The following list outlines some of the changes from the previous edition of Displaying Your Findings: Many figures include confidence intervals (this is particularly true for bar graphs and line graphs) If researchers wish to use color in their figure or present numerous images in an article intended for publication, they should first check the journal submission guidelines or department and university guidelines to determine acceptability of color figures and pictures and the specifications of those color figures (e.g., image size in terms of bytes) and to determine whether the journal publishes color figures or offers alternative online-only publication venues for those particular figures It is up to the individual researcher to determine whether color should be used in conference posters or presentations The font for each figure caption matches the rest of the text The font size in a figure can be as small as points or as large as 14 points but not smaller or larger Text in the figure can be single-, one-and-a-half-, or double-spaced Text in the figure caption should be double-spaced As before, each figure appears on its own page, but now figure captions are placed on the same page below the figure rather than on a separate page The preference is to not use a lot of different types of shading Ideally, any shading used should make it easy to distinguish one object (e.g., bar) from another (e.g., gray, black, and white) The Publication Manual indicates a preference for no more than three types of shading Acknowledgments In writing both versions of this book, we received assistance from many people We thank all of the reviewers for their useful comments; our research assistants; and the staff of APA Books, who made this a pleasurable experience Adelheid Nicol dedicates this book to her husband, Yves Mayrand, and their three children, Ariane, Amélie, and Mathieu Penny Pexman dedicates this book to her husband, Dave Pexman, and their two children, John and Kate 178 D I S P L AY I N G Y O U R F I N D I N G S ways this technology can fail For instance, there can be problems connecting the computer to the data projector, problems adjusting the colors created by the data projector, and problems when presentations are created on one platform or with one version of software and then played on a different platform or with a different version of software These problems can usually be fixed but take up valuable presentation time It is best to make sure that all aspects of your presentation are working well in advance of your presentation start time by arriving early and testing your presentation A word of caution about computer presentations: Sometimes presenters are overzealous in their use of animation (e.g., each line of text “flies” onto the screen from different directions) or sound (e.g., each line of text is accompanied by sound effects) Overuse of animation can be distracting to the audience The special features of computer presentation software should be used sparingly to enhance key points The following tips can help presenters using a computer maximize the effectiveness of their presentation: Ⅲ Use sound effects and animation only to enhance a particular point in the talk Ⅲ If possible, use a remote mouse This will allow you to move away from the computer while speaking Ⅲ Make sure the contrasts between text and background are good under any lighting conditions (a dark room or bright room) Ⅲ Practice going back to a particular slide in the presentation sequence An audience member may ask a question that requires you to show a slide from the middle of the presentation Also, during the presentation you might accidentally advance the slides and wish to back up Ⅲ Make sure that the presentation is set to advance slides with a mouse click Presetting a time (duration) for each slide makes the presentation hands free but also requires the presenter to stick to a very strict schedule for the presentation Ⅲ If using a new version of a software program, make sure you also create a separate file for the same presentation and save it as an older version of the program so that if the conference does not have the latest version of the program, you will still be able to open your file Ⅲ Time your presentation so that you know how long it will take Ⅲ Determine beforehand which material you would delete from your presentation if you had less time than you originally thought you would have Ⅲ Practice your presentation with slide transitions Laser pointer A laser pointer is a handheld device that casts a small circle of red light onto a screen Presenters can use it to point to a particular part of a projection screen Laser pointers must be used with caution; the beam can cause retinal damage if it is cast directly at someone’s eye Format Color The use of color on slides can enhance a presentation Strong, bright colors should be used, and cluttered backgrounds should be avoided A consistent color theme should be used throughout the presentation With the exception of photographs, which can have many colors, no more than two to three colors should be used per slide The following are V I S U A L S F O R P R E S E N TAT I O N S effective color combinations that also work for people who are color-blind: Ⅲ Ⅲ Ⅲ Ⅲ black on white, red on white, turquoise on black, and magenta on black Number of slides in a presentation Many people find that their talk is well timed if they budget one slide for every to of talk time Each should address only one main point or issue Fonts If the slides are projected onto a standard screen, and the room is not too large, a font of at least 24 points should suffice for text (larger is almost always better) The font style and color should be consistent across all slides Standard capitalization rules should be followed; text in all capital letters is difficult to read Italic rather than bold or underlining is best to highlight points A single style for bullet lists should be used throughout the presentation More than one bullet shape can be used to show different levels of bulleting (as in some of the figures in this chapter), but the system should be consistent throughout Text The text on slides should be as concise as possible The text should usually take the form of points rather than paragraphs The text should reinforce, but not match, what the speaker is saying In general, slides should include at least the following (not an exhaustive list): Ⅲ Ⅲ Ⅲ Ⅲ Ⅲ Ⅲ Ⅲ author’s title and affiliation, diagram explaining the study design, diagram explaining the procedure, pictures of stimuli or procedure, table or figure summarizing results, discussion, and acknowledgment of collaborators and funding agencies.1 Also, consider preparing an extra slide or two to help answer questions you anticipate from the audience These might summarize additional analyses or plans for future research designs Handouts Handouts are used in certain disciplines (e.g., linguistics) when the stimuli and examples are complex When a presenter gives the audience handouts, they can refer back to the examples throughout the talk Many handouts include only the slides used in the presentation plus any references Although providing full-scale handouts is an option, a lot less paper is used (and wasted) if more than one slide is included on each page Handouts can be an asset in talks where the presenter really wants to make a lasting impression (e.g., job For further information about preparing visuals for presentations, consult the following sources: Kosslyn, S M (2007) Clear and to the point: psychological principles for compelling PowerPoint presentations New York, NY: Oxford University Press; Morgan, S., & Whitener, B (2006) Speaking about science: A manual for creating clear presentations New York, NY: Cambridge University Press 179 180 D I S P L AY I N G Y O U R F I N D I N G S talks) because audience members get something to take away with them and the presenter appears well prepared The downside to handouts is that the audience can skip ahead, reading the handout and not paying attention to the speaker Handouts should include the following: Ⅲ a cover sheet with the title of the research, all authors and affiliations, and contact numbers or addresses or both; Ⅲ the slides presented as well as any additional images that would not have appeared clearly on a projector; Ⅲ efficient use of space—more than one slide is included on each page, with handouts printed double-sided (pages numbered); and Ⅲ references cited in the presentation Example 14.1 A researcher was interested in autobiographical memory, particularly the nature of the events that are remembered from one’s life The researcher wanted to determine whether people’s memory for events is influenced by three factors: (a) age at the time of the memory, (b) how surprising the event was, and (c) how positive the event was The researcher assessed the frequency of memories for four types of events: surprising positive events (e.g., winning the lottery), surprising negative events (e.g., injury in an accident), unsurprising positive events (e.g., graduating from college), and unsurprising negative events (e.g., death of a parent after a long illness) The participants were 60 individuals aged 50 to 60 years Testing involved two separate sessions The first session was a personal interview in which participants were asked to recount 10 memories from each decade of their lives In the second session, days later, participants were asked to decide, for each of the memories they had recounted, whether they remembered the event as surprising or not surprising and whether they remembered it as positive or negative The researcher prepared slides for a 15-min talk, shown in Figures 14.1–14.10 Variables for Example 14.1 Independent Variables Age at time of memory (decades 0–9, 10–19, 20–29, 30–39, 40–49) Surprise of event (surprising, not surprising) Positivity of event (positive, negative) Dependent Variable Frequency of memories V I S U A L S F O R P R E S E N TAT I O N S Ⅵ Figure 14.1 Slide of Sample Presentation The Good Old Days? Investigating the Content of Autobiographical Memories Natalie Smith, Jordan Jones, and Kate Green The text font should be at least 24 points The color combination should be effective and consistent The first author is usually (but not always) the person giving the talk Anywhere State University Ⅵ Figure 14.2 Slide of Sample Presentation What Is Autobiographical Memory? Memory for events in our lives Changes across life span in the number of memories: o Childhood amnesia o Reminiscence bump o Recency Ⅵ Figure 14.3 Slide of Sample Presentation What Is the Content of Autobiographical Memories? Memories for emotional events (e.g., Cole, 2009) Unanswered questions Positive or negative emotions? Surprising or nonsurprising events? Wording slide titles as questions can be an effective presentation strategy 181 D I S P L AY I N G Y O U R F I N D I N G S Ⅵ Figure 14.4 Slide of Sample Presentation Present Research Purpose Amount of text on the screen should be kept to a minimum Investigate content of autobiographical memories o Positive/negative o Surprising/nonsurprising Ⅵ Figure 14.5 Slide of Sample Presentation Method Participants 60 individuals aged 50 to 60 years Procedure: Session Recount 10 memories per decade Session 2 days Rate memories: (a) surprising? (b) positive? Aspects of the methodology are usually presented in the same order they would appear in an APA-formatted paper (e.g., participants, materials, procedure) Font and style will often depend on the overall design requirements of the presentation and may differ from what would be used in a paper Ⅵ Figure 14.6 Slide of Sample Presentation 70 Surprising-Positive Unsurprising-Positive Surprising-Negative Unsurprising-Negative 60 50 Percentage 182 40 30 20 10 0–9 10–19 20–29 30–39 40–49 Age at Time of Memory (Decade) Keep graphics simple V I S U A L S F O R P R E S E N TAT I O N S Ⅵ Figure 14.7 Slide of Sample Presentation Results Proportion of memories for surprising, negative events increased across the life span Proportion of memories for surprising, positive events decreased across the life span Proportion was higher of surprising than nonsurprising memories across the life span Ⅵ Figure 14.8 Slide of Sample Presentation Why More Surprising Memories? Surprising = distinctive? o Many of the memories were of novel experiences Surprising = traumatic? o Many of the memories were of unexpected accidents Surprising = life altering? o Many of the memories were of new and unexpected opportunities Ⅵ Figure 14.9 Slide of Sample Presentation Why More Surprising, Negative Memories in Later Decades? Erosion of tendency to “remember the good times”? Future research required to systematically evaluate these possibilities 183 184 D I S P L AY I N G Y O U R F I N D I N G S Ⅵ Figure 14.10 Slide 10 of Sample Presentation Conclusions Content of autobiographical memories varies across the life span o In early decades, tendency to report memories of surprising, positive events A reference slide would require too much text Presenters can provide references to the audience in a handout o In later decades, tendency to report memories of surprising, negative events Ⅵ Checklist for Effective Visuals for Presentations Ⅲ Ⅲ Ⅲ Ⅲ Ⅲ Ⅲ Ⅲ Ⅲ Font type, size, and color are consistent across slides Ⅲ Ⅲ If multiple figures are used, axes are consistent across figures where possible Text is large enough to be read from a distance (at least 24 points) There are no more than 12 lines of text per slide Text is clearly organized (e.g., using bullets or numbering) Text is limited to that which is absolutely necessary One main idea or topic is on each slide Color scheme (if any) is consistent Color combinations are carefully considered; bright colors give a professional appearance Only key findings (those related to hypotheses and conclusions) are presented Index A Abbreviations, 13, 34, 49, 116, 117 Abstracts, 165 Acknowledgments section, 165, 174 Address labels, 167 Affiliations, 165 Agglomerative cluster analysis, 125–126
