The Effect of Threatening Stimuli on Attentional Blink
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.
期刊介绍:
The journal Stress aims to provide scientists involved in stress research with the possibility of reading a more integrated view of the field. Peer reviewed papers, invited reviews and short communications will deal with interdisciplinary aspects of stress in terms of: the mechanisms of stressful stimulation, including within and between individuals; the physiological and behavioural responses to stress, and their regulation, in both the short and long term; adaptive mechanisms, coping strategies and the pathological consequences of stress.
Stress will publish the latest developments in physiology, neurobiology, molecular biology, genetics research, immunology, and behavioural studies as they impact on the understanding of stress and its adverse consequences and their amelioration.
Specific approaches may include transgenic/knockout animals, developmental/programming studies, electrophysiology, histochemistry, neurochemistry, neuropharmacology, neuroanatomy, neuroimaging, endocrinology, autonomic physiology, immunology, chronic pain, ethological and other behavioural studies and clinical measures.
