Introduction Inattentional Blindness: missing a salient stimuli when busy performing a task Simons and Chabris (1999) Gorillas in Our Midst study
Variables
Independent Variables – Priming/Non-Priming Words – Attention Set • Red • Blue
Dependent Variable – Rate of Inattentional Blindness
Methods
55 participants (29 male & 26 female) Mean Age = 19.4 Participants were randomly assigned to one of the following conditions
Priming Red Priming Blue Non-Priming Red Non-Priming Blue
Results Overall 49.1% of the participants missed red and blue superhero character x² (6, N=55) = 7.629, p=.267 Priming Group: 40% (12 of 30) Non-Priming Group: 64% (16 of 25)
Priming

Red
37.5% (6 of 16)
69.2% (9 of 13)
Blue
42.8% (6 of 14)
58.3% (7 of 12)
Discussion
The study demonstrated inattentional blindness. Based upon the results, it can be inferred that priming does not have an effect upon inattentional blindness – May need to run more participants to be sure that this is the case Results support the early selection theory of attention (Lachter, Forster, & Ruthruff, 2004) – No perception without attention (Mack & Rock, 1998) Future Directions: – Neutralizing Attention Sets – Reduce Cognitive Load
