LITERATURE REVIEW
Multimedia Effects
Multiple modality story
Variables
Credibility
Newsworthiness
Recall
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
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.
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.
METHOD CONTINUED
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.
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).

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
Time control
Future Research Number of multimedia elements
Type of multimedia elements
More dependent variables
