“…The dissociation between face-specific and other object-specific size invariance, and its relation to emotion processing, remains an intriguing subject for future research. Moreover, the induced perception of physical proximity through additional contextual cues, such as depth-cued backgrounds, has been shown to enhance the early processing of anger expressions in looming faces 27 , 28 . This raises the question of the timing and mechanism of the integration of the physical distance of faces in lower- and higher-level processes.…”

“…Two studies reported interactions between stimulus size and emotional valence at mid-latency occipito-temporal components: for pleasant compared to neutral scenes between 150 and 300 ms 25 ; for positive and negative compared to neutral words between 340 and 480 ms 24 , whereas no interactions at early and later processing stages were found. In contrast, enhanced early effects (P1) have been reported for looming (i.e., size-increasing) angry compared with neutral faces 27 , 28 , and also the face-sensitive N170 has shown to be elevated for looming fearful compared with neutral faces 30 . Moreover, later effects (P3) were reported to be modulated by size for pain-administered faces 29 .…”

“…Notably, few studies have used event-related potentials (ERPs) to examine the influence of stimulus size on the neurophysiological processing of emotional stimuli (e.g., words 24 ; emotional scenes 25 ; feedback processing 26 ; looming faces 27 , 28 ; faces with administered pain 29 ; and peripherally threatening fearful and neutral faces 30 ) over time. Two studies reported interactions between stimulus size and emotional valence at mid-latency occipito-temporal components: for pleasant compared to neutral scenes between 150 and 300 ms 25 ; for positive and negative compared to neutral words between 340 and 480 ms 24 , whereas no interactions at early and later processing stages were found.…”

Seeing an angry individual in close physical proximity can not only result in a larger retinal representation of that individual and an enhanced resolution of emotional cues, but may also increase motivation for rapid visual processing and action preparation. The present study investigated the effects of stimulus size and emotional expression on the perception of happy, angry, non-expressive, and scrambled faces. We analyzed event-related potentials (ERPs) and behavioral responses of N = 40 participants who performed a naturalness classification task on real and artificially created facial expressions. While the emotion-related effects on accuracy for recognizing authentic expressions were modulated by stimulus size, ERPs showed only additive effects of stimulus size and emotional expression, with no significant interaction with size. This contrasts with previous research on emotional scenes and words. Effects of size were present in all included ERPs, whereas emotional expressions affected the N170, EPN, and LPC, irrespective of size. These results imply that the decoding of emotional valence in faces can occur even for small stimuli. Supra-additive effects in faces may necessitate larger size ranges or dynamic stimuli that increase arousal.

The accurate estimation of time‐to‐collision (TTC) is essential for the survival of organisms. Previous studies have revealed that the emotional properties of approaching stimuli can influence the estimation of TTC, indicating that approaching threatening stimuli are perceived to collide with the observers earlier than they actually do, and earlier than non‐threatening stimuli. However, not only are threatening stimuli more negative in valence, but they also have higher arousal compared to non‐threatening stimuli. Up to now, the effect of arousal on TTC estimation remains unclear. In addition, inconsistent findings may result from the different experimental settings employed in previous studies. To investigate whether the underestimation of TTC is attributed to threat or high arousal, three experiments with the same settings were conducted. In Experiment 1, the underestimation of TTC estimation of threatening stimuli was replicated when arousal was not controlled, in comparison to non‐threatening stimuli. In Experiments 2 and 3, the underestimation effect of threatening stimuli disappeared when compared to positive stimuli with similar arousal. These findings suggest that being threatening alone is not sufficient to explain the underestimation effect, and arousal also plays a significant role in the TTC estimation of approaching stimuli. Further studies are required to validate the effect of arousal on TTC estimation, as no difference was observed in Experiment 3 between the estimated TTC of high and low arousal stimuli.
