Effects of Color versus Black and White Pictures on Children's Storytelling Buffy Dubreuil, Reane Laurin, and Phyllis Schneider Department of Speech Pathology & Audiology, University of Alberta Does color make a difference? Previous research: the ways stories are presented to children will affect the quality of stories they tell/retell (Schneider, 1996; Schneider & Dubé, 1997, 2005) There appears to be an assumption that color pictures are preferable to black and white ones Evidence: requests to color the pictures of the Edmonton Narrative Norms Instrument (ENNI) Research on the issue is very limited (studies of test stimuli found no effects – Brownell, 2000; Husband & Hayden, 1996) It is possible that color might make a difference in a narrative context Might attract and hold children’s attention better Might help them focus on salient elements Current study compared story stimuli in color and black and white on measures of story quality and quantity Research question: Does the type of visual stimuli (color versus black and white) affect children’s narratives as measured by 1) story grammar, 2) number of words, or 3) number of different words? Methods Participants 22 children aged 4-6 Mean 59.98 mos. (SD 7.52 mos.) range 48.30-77.77 mos. attended preschools or daycares in Edmonton, AB Materials Pictures from the Edmonton Narrative Norms Instrument* (ENNI; Schneider, Hayward, & Dubé, 2006) – first episodes of stories A3 and B3 (5 pictures each) A color version of each story was created See first picture from each story in color and black and white below Procedure Each child was seen individually in his/her preschool All children first told the ENNI* training story Then child told one of each story and condition (total of 2 stories) Presentation of story (A3, B3) and condition (color, B&W) was counterbalanced Examiner prompts were limited Stories were audiotaped and later transcribed Stories were scored for Story Grammar (ENNI*) Total Number of Words and Number of Different Words was calculated using CLAN Data analysis Stories told in the Color and B&W conditions were compared using paired samples t-tests Alpha:.05 for each test Beta:.30 (to provide a level higher than which a non-significant result would be considered truly not significant) *See the ENNI website for more information about the ENNI: www.rehabmed.ualberta.ca/spa/enni No comparison was significant. All p values exceeded the Beta of.30 (ranging from.72-.87) Thus in no case did children provide more or better information with color pictures 17 of the children were also asked which story they preferred 9 preferred the story they saw in color but: only 4 said they preferred it because of color 7 preferred the story they saw in black and white 1 liked both equally Reasons given for preference: most commonly, something about the story content (type of animal, setting, etc.) Conclusion: The same results will be obtained with color and black-and-white picture stimuli.
