The eyewitness experience is extraordinarily complex, given the influence of attentional-related phenomena, such as the weapon focus effect and inattentional blindness. There remains uncertainty as to how the weapon focus effect might occur in relation to inattentional blindness, and how the unusualness of a weapon might shape these experiences. Therefore, this study investigated the influence of context and the weapon focus effect within an inattentional blindness paradigm. Naive participants completed a dual counting task whilst they viewed a short video of a busy medical centre or classroom setting. During this video, an actor walked into the scene and held out a stethoscope or a gun. Post-video questions revealed that most participants missed the object's presentation, however, the gun was significantly more likely to be noticed than the stethoscope. There was also no difference between rates of inattentional blindness for the stethoscope across the different conditions. Further, eye-tracking data found no statistically significant difference in fixation across the conditions. It did, however, reveal that some participants spent time fixating on the object despite experiencing inattentional blindness. Therefore, this study challenged the role of unusualness in eliciting the weapon focus effect and showed that weapons do not always capture attention during attention-demanding tasks. It also showed that fixations towards the weapon does not always result in conscious recognition. This study has implications for understanding how attention can influence eyewitness testimonies. Future research should consider the role of threat in eliciting the weapon focus effect within this paradigm.
