“…Given that emotional information draws attentional resources away from inhibition processing, the subjects had to inhibit emotional processing in order to accomplish the task, thereby leading to an inverted N2. These findings are consistent with Yu et al’s [23] study and a previous study in our laboratory [24] in which N2 was found to be smaller for emotional conditions than for neutral condition. Thus, in the present experiment, the smaller N2 in the NP condition may be a reflection of individuals controling and shifting their attention away from the position where threatening pictures had been presented previously.…”

This study used the location negative priming (NP) paradigm and the recording of event related potentials (ERPs) to examine the mechanism of the impact of emotional stimulus on subsequent spatial attentional processing. The results showed relative to the happy and neutral condition, a significant behavioural NP effect, as well as decreased N2, increased N2pc and P3 amplitudes for NP condition were found selectively in the fearful prime distractor condition. These findings suggest that the effect of fearful stimulus on location NP may be related to early inhibition processing. Larger P3 amplitudes may reflect the use of increased cognitive resources when one is necessary for overcoming the tendency to avoid viewing the position where a fearful stimulus has recently been seen.

“…Few studies have directly investigated how emotional stimuli interact with neural timing systems to modulate temporal distortions (e.g., 56, 77, 89, 167, 181, 233, 240). A neurobiologically inspired model of time perception, namely the SBF model (4, 158, 159), in conjunction with known mechanisms by which affective stimuli modulate neural activity, may provide an important starting point for assessing how emotional stimuli modulate the inputs and/or outputs of neural timing systems.…”

Like other senses, our perception of time is not veridical, but rather, is modulated by changes in environmental context. Anecdotal experiences suggest that emotions can be powerful modulators of time perception; nevertheless, the functional and neural mechanisms underlying emotion-induced temporal distortions remain unclear. Widely accepted pacemaker-accumulator models of time perception suggest that changes in arousal and attention have unique influences on temporal judgments and contribute to emotional distortions of time perception. However, such models conflict with current views of arousal and attention suggesting that current models of time perception do not adequately explain the variability in emotion-induced temporal distortions. Instead, findings provide support for a new perspective of emotion-induced temporal distortions that emphasizes both the unique and interactive influences of arousal and attention on time perception over time. Using this framework, we discuss plausible functional and neural mechanisms of emotion-induced temporal distortions and how these temporal distortions may have important implications for our understanding of how emotions modulate our perceptual experiences in service of adaptive responding to biologically relevant stimuli.

Time perception has been shown to be altered by emotions. This study employed event-related potentials (ERPs) to examine the effects of two threat-related emotions on the judgment of time intervals in the range of 490–910 ms. We demonstrated that disgust and fear have distinct influences on time perception. At the behavioral level, disgusted faces were estimated longer and fearful faces were estimated shorter (i.e., the generalization gradient for the disgusted faces was shifted left while the generalization gradient for the fearful faces was shifted right) when compared with neutral faces. Accordingly, the contingent negative variation, an online ERP index of timing, displayed larger area in disgust and smaller area in fear conditions when compared with neutral condition (disgust = 1.94 ± 2.35 μV•s, neutral = 1.40 ± 2.5 μV•s, and fear = 1.00 ± 2.26 μV•s). These findings indicated that specific neural mechanisms may underlie the attention effects of different subtypes of threat-related emotions on timing; compared with neutral faces, fearful faces are likely to attract more attentional resources while disgusted faces may attract less attentional resources for emotional processing. The major contribution of the current study is to provide neural correlates of fear vs. disgust divergence in the aspect of time perception and to demonstrate beyond the behavioral level that the categorization of threat-related emotions should be refined so to highlight the adaptability of the human defense system.
