Background This study attempted to examine the impact of each cognitive processing style (bottom-up, top-down) on attention patterns following a traumatic experience by measuring attentional blink (AB).
Methods Participants were 37 university students with no direct experience of traffic accidents. They were randomly assigned to either a single-task (bottom-up processing) group or a dual-task (top-down processing) group, who performed the Rapid Serial Visual Presentation (RSVP) after watching an analogue trauma video. The correct response rate to target stimuli was then compared between groups based on stimulus type and stimulus presentation interval.
Results In the dual-task group, no significant differences were found. However, in the single-task group, a trend towards a decrease in the correct response rate to the target stimulus was observed 200 ms after the presentation of the traumatic stimulus (i.e., AB).
Conclusions This tendency can be explained by the phenomenon of automatic attentional capture by traumatic stimuli, suggesting a relationship between bottom-up processing and attentional bias.
Background This study aimed to identify the effect of momentary Attentional Blink (AB) in temporarily stressful situations to reveal the relationship between emotion and attention after a traumatic experience.
Methods Participants were 57 college students randomly assigned to either an experimental group (n=30) that watched news videos depicting disasters or a control group (n=27) that did not watch them. This was followed by the Rapid Serial Visual Presentation (RSVP) task for both groups. AB appeared when T1 was a news threat stimulus for the experimental and control group; the shorter the presentation interval between T1 and T2, the stronger the AB. On the other hand, when news-neutral stimuli were presented in T1, the AB pattern between the groups changed. The AB pattern appeared regardless of the type of word presented to the control group in T1; however, in the experimental group, the AB pattern appeared only when the news-neutral word was presented in T1.
Results The results suggest that AB appears when T1 is a traumatic stimulus. However, when T1 is a conditioned traumatic stimulus, the AB pattern varies depending on whether the participant watched the disaster video.
Conclusions Our results expand on existing studies by confirming the AB effect in trauma-related neutral stimuli and trauma stimuli.
