  2. Introduction • Multimedia • Internet-based • Convergence Journalism

  3. Literature Review • Multimedia Effects • Multiple modality story • Variables • Credibility • Newsworthiness • Recall

  4. Research question • RQ：Do multiple multimedia elements influence an online news story’s credibility, newsworthiness, and recall? • Hypothesis: Multimedia elements will enhance a news story’s: • (1) Credibility • (2) Newsworthiness • (3) Recall

  5. Method • Experiment • One-Factor Within-Subjects Design • Post-Test Only • Variables • IV: Modality 1) text-only 2) text with multiple multimedia elements (text plus photos, audio, and video) • DV: Credibility, newsworthiness, and recall.

  6. Method Continued • Sample (1) Sixty students from Midwest University. (2) Random sample & snowball sampling. • Procedure (1) News stories and questionnaires posted on SurveyGizmo. (2) Emails to subjects. • Stimuli (1) Text-only stories: a) carbon footprint of orange juice, b) baseball bat production, and c) rope climbing to maintain wind turbines. (2) Multimedia stories: a) immigration and assimilation in U.S. high schools, b) sea turtle extinction, and c) safety of tap water. (3) 500 words text & video without stamp. (4) Random orders according to last name.

  7. Method Continued -- Measures • Credibility • Believability, objectivity, trustworthiness, fairness, accuracy, and thoroughness of the news’ story. • 9-item Likert-type scales. • Newsworthiness • Significance or effect, interest or relevance. • 9-item Likert-type scales. • Recall • Comprehensibility • Fill-in-the-blank & multiple choice questions.

  8. Results • Use repeated-measures ANOVA to analyze each hypothesis. • Credibility • Supported (F(1, 47) = 8.394, p = .006 < .01 → Text-only < Multimedia). • Newsworthiness • Supported (F(1, 47) = 36.726, p = .000 < .001 → Text-only < Multimedia). • Recall • Supported (F(1, 36) = 8.969, p = .005 < .01 → Text-only < Multimedia). Mean Score

  9. discussion • Implications • Multimedia stories are perceived as more credible and newsworthy than text-only stories,and participants could remember more details from stories with multiple multimedia elements than from stories that were text-only. • Limitations • Timecontrol • FutureResearch • Numberofmultimediaelements • Typeofmultimediaelements • Moredependentvariables
