| Abstract | Tested the hypothesis that negative emotions lead to a reduced information-processing capacity and that this is observable even on a very basic level of information processing. In an experimental study, 102 participants (aged 18-44 years) were assigned to 3 independent groups. By means of a 3-minute video, either a negative, a positive, or a neutral mood was then induced. Shortly after the video, 2 acoustic stimuli with increasing information were presented, while the P3 component of the event-related brain potential on these stimuli was measured as a psychophysiological indicator of cognitive resource allocation. In addition, the experimental manipulation was checked by assessing subjective and external mood ratings as well as cortical alpha activity. Results show that the videos did in fact induce positive, neutral, or negative mood. Moreover, even when controlling for video-related unspecific cortical arousal, a significant emotional aftereffect was found on the P3 component of the event-related brain potential, indicating reduced information-processing capacity, particularly in the negative mood condition. The data support H. C. Ellis and P. W. Ashbrook's model of emotional aftereffects on cognitive processes. As those effects were observable after an event that did not demand a high amount of cognitive resources, this suggests that even tasks that do not heavily engage central processing resources and are not likely to be influenced by cognitive strategies seem to be affected by a negative emotional state.
