PREVIOUS RESEARCH:
Recall seven digits either in silence, irrelevant speech, vocal music, or instrumental music.
Participants were able to recall more digits when recalling in silence, than in any other condition

PREVIOUS RESEARCH
University undergraduates studied twenty lists in backgrounds of similar onset words, rhyming words, dissimilar words or in silence
No significant difference between any of the conditions, other than the silence condition, in which students recalled the most amount of words
Baddeley, & Salame, 1982

PROCEDURE
Participants randomly assigned to two groups.
• Control Group: 12 words presented on PowerPoint in silence.
• Experimental Group: 12 words presented with visual distraction (image in the background) and auditory distraction (song playing on speakers).

RESULTS
Experimental Group (Distractions) -M = 5.50 -SD = 1.43 Control Group (No Distractions) -M = 3.9 -SD = 1.10

RESULTS
t(18) = 2.799, p = .174.
The results failed to support our hypothesis and are not in agreement with previous research.
