Previous studies have shown that the perceived duration of symmetrical visual patterns is longer than that of asymmetrical ones. In a different context, regular visual stimuli have been found to be judged as lasting longer than irregular ones. A recent replication study reported that the effect of symmetry on time perception might not be robust; however, the study jumbled the effects of regularity and symmetry. The stimuli used in our previous study on the effect of regularity were qualitatively and quantitatively different from those used in the study addressing symmetry. Moreover, the hypothesized underlying mechanisms involved in the effects of regularity and symmetry were completely different. Taken together, the present commentary claims that combining these findings based on the superficial similarity of these phenomena would lead to flawed scientific discussions.

When looking at visual stimuli, context often easily affects elements of perception and cognition such as aesthetic evaluation, memory, and time perception. However, the relationships between aesthetic evaluation and time perception as influenced by context are not fully understood. This study’s aim was to examine whether context can influence not only aesthetic evaluation but also time perception. To achieve this, a temporal reproduction task was used. Participants viewed stimuli in either an art context or a realistic context. Identical affective pictures were presented in one of three durations (2500 ms, 4500 ms, or 6500 ms) and the participants reproduced their perceived viewing time for each picture. The pictures were rated as more pleasant when viewed in the art context compared to the realistic context. Additionally, the perceived duration of identical visual stimuli differed according to the particular context. Thus, contextual differences were found to be attributed to different operations of a switch within the internal clock. In sum, context can influence both aesthetic evaluation and time perception.

The neural basis of time perception remains unknown. A prominent account is the pacemaker-accumulator model, wherein regular ticks of some physiological or neural pacemaker are read out as time. Putative candidates for the pacemaker have been suggested in physiological processes (heartbeat), or dopaminergic mid-brain neurons, whose activity has been associated with spontaneous blinking. However, such proposals have difficulty accounting for observations that time perception varies systematically with perceptual content. We examined physiological influences on human duration estimates for naturalistic videos between 1–64 seconds using cardiac and eye recordings. Duration estimates were biased by the amount of change in scene content. Contrary to previous claims, heart rate, and blinking were not related to duration estimates. Our results support a recent proposal that tracking change in perceptual classification networks provides a basis for human time perception, and suggest that previous assertions of the importance of physiological factors should be tempered.

In the domain of aesthetic preference, previous studies focused primarily on exploring the factors that influence aesthetic preference while neglecting to investigate whether aesthetic preference affects other psychological activities. This study sought to expand our understanding of time perception by examining whether aesthetic preference in viewing paintings influenced its perceived duration. Participants who preferred Chinese paintings ( n = 20) and participants who preferred western paintings ( n = 21) were recruited to complete a temporal reproduction task that measured their time perception of Chinese paintings and of western paintings. The results showed that participants who preferred Chinese paintings exhibited longer time perceptions for Chinese paintings than for western paintings, while the participants who preferred western paintings exhibited longer time perceptions for western paintings than for Chinese paintings. These results suggested that aesthetic preference could modulate our perceived duration of painting presentation. Specifically, individuals perceive longer painting presentation durations when exposed to the stimuli matching their aesthetic preferences.

The accuracy with which observers could judge whether two visual stimuli were the same or different was measured with the rating method of detection theory. For judgments of whether two pictures referred to natural or manufactured things, the shape of the obtained receiver operating characteristic (ROC) was consistent with the observers adopting an optimal decision strategy. A similar result was found for judgments of complex but meaningless visual patterns. For judgments of whether two colours that differed along a simple sensory dimension were the same or different, however, the resulting ROC was consistent with the observers adopting a suboptimal differencing strategy. The accuracy of the judgments did not depend on the visual field to which the stimuli were presented.

While the effects of synthesised visual stimuli on time perception processes are well documented, very little research on time estimation in human movement stimuli exists. This study investigated the effects of movement speed and agency on duration estimation of human motion. Participants were recorded using optical motion capture while they performed dance-like movements at three different speeds. They later returned for a perceptual experiment in which they watched point-light displays of themselves and one other participant. Participants were asked to identify themselves, to estimate the duration of the recordings, and to rate expressivity and quality of the movements. Results indicate that speed of movement affected duration estimations such that faster speeds were rated longer, in accordance with previous findings in non-biological motion. The biasing effects of speed were stronger for watching others’ movements than for watching one’s own point-light movements. Duration estimations were longer after acting out the movement compared with watching it, and speed differentially affected ratings of expressivity and quality. Findings suggest that aspects of temporal processing of visual stimuli may be modulated by inner motor representations of previously performed movements, and by physically carrying out an action compared with just watching it. Results also support the inner clock and change theories of time perception for the processing of human motion stimuli, which can inform the temporal mechanisms of the hypothesised separate processor for human movement information.

Previous studies have shown that the perceived duration of visual stimuli can be strongly distorted by auditory stimuli presented simultaneously. In this study, we examine whether sounds presented separately from target visual stimuli alter the perceived duration of the target’s presentation. The participants’ task was to classify the duration of the target visual stimuli as perceived by them into four categories. Our results demonstrate that a sound presented before and after a visual target increases or decreases the perceived visual duration depending on the inter-stimulus interval between the sounds and the visual stimulus. In addition, three tones presented before and after a visual target did not increase or decrease the perceived visual duration. This indicates that auditory perceptual grouping prevents intermodal perceptual grouping, and eliminates crossmodal effects. These findings suggest that the auditory–visual integration, rather than a high arousal state caused by the presentation of the preceding sound, can induce distortions of perceived visual duration, and that inter- and intramodal perceptual grouping plays an important role in crossmodal time perception. These findings are discussed with reference to the Scalar Expectancy Theory.
