Analysis of Different Types of Attentional Interference Compared to Working Memory

Previous studies have shown a relationship between working memory (WM) and the Color-Word Stroop Task (CWS). Newer Stroop-like tasks such as the Color-Block Stroop-like Task (CBS) have been shown to cause interference but the nature of the interference is unclear. This study attempted to compare CWS and CBS to tests of working memory, specifically the Digits Span Backward task (DB) and an Operation Span (OSPAN) task. The first experiment involved no auditory stimuli. No significant correlation was found between WM and CWS. This led to a second experiment with the digit span administered auditorily. Again, no significant correlation between CWS and WM was found. Inadequate attentional load is believed to be the most probable cause for the lack of correlation. Results of other findings are discussed in light of these results and suggestions for future research are put forth
