This study investigated whether humans recognize different emotions conveyed only by the kinematics of a single moving geometrical shape and how this competence unfolds during development, from childhood to adulthood. To this aim, animations in which a shape moved according to a happy, fearful, or neutral kinematics were shown, in a forced-choice p...

We report an effect of anomalous transparency that is similar to other phantom effects. In an experiment aimed at testing the combined role of (i) motion of the occluding surface and (ii) lightness contrast and polarity on the perception of anomalous transparency, we found that transparency is perceived only with low contrast, and enhanced when the...

We present results from two experiments aimed at studying the direction of Mona Lisa's gaze and its affective expression. In experiment 1 we studied the effect of retinal image size on the perception of her gaze by manipulating observation distances of a high-quality print of the painting. Participants (N = 30) were asked to answer a simple questio...

Digital contact tracing apps have been introduced by governments as a strategy to limit the spread of the COVID-19 pandemic. Digital contact tracking is an alternative to traditional contact tracing performed by human tracers who have to reconstruct each contact an infected person had in the recent past by means of interviews. The Italian governmen...

In this study, we investigated whether the difficulties in body motion (BM) perception may led to deficit in emotion recognition in Autism spectrum disorder (ASD). To this aim, individuals with high-functioning ASD were asked to recognise fearful, happy, and neutral BM depicted as static images or dynamic point-light and full-light displays. Result...

According to the Polyvagal theory, the vagus nerve is the key phylogenetic substrate that supports efficient emotion recognition for promoting safety and survival. Previous studies showed that the vagus nerve affects people’s ability to recognize emotions based on eye regions and whole facial images, but not static bodies. The purpose of this study...

With the increasing presence in our lives of interactive and technological items, the concept of “experience” becomes crucial in both the design and the evaluation phases. When aiming to measure such experience, researchers typically adopt self-report methodology. However, it has been established that also unconscious motives (i.e., emotions, impli...

Full-text available
E-motions are defined as those affective states the expressions of which—conveyed either by static faces or body posture—embody a dynamic component and, consequently, convey a higher sense of dynamicity than other emotional expressions. An experiment is presented, aimed at testing whether e-motions are perceived as such also by individuals with aut...

Background Neuroimaging studies suggest that the inferior frontal operculum (IFO) is part of a neuronal network involved in facial expression processing, but the causal role of this region in emotional face discrimination remains elusive. Objective We used cathodal (inhibitory) tDCS to test whether right (r-IFO) and left (l-IFO) IFO play a role in...

Full-text available
In the present study, we examine how person categorization conveyed by the combination of multiple cues modulates joint attention. In three experiments, we tested the combinatory effect of age, sex, and social status on gaze-following behaviour and pro-social attitudes. In Experiments 1 and 2, young adults were required to perform an instructed sac...

Illusory Line Motion (i.e., a static line, presented after a lateral cue, is perceived as movement in the opposite direction to the cue) has been used to study a phenomenon of perceptual asymmetry. We have demonstrated the presence of an illusion of leftward movement, even in the presence of bilateral symmetrical cues. We have classified this pheno...
Article
Transcutaneous vagus nerve stimulation (tVNS) has been shown to promote inferences of emotional states based on eye-related information provided by facial expressions of emotions. Eye gaze direction can influence the allocation of attentional sources when processing facial emotional stimuli. Here we sought for further evidence indicating whether tV...

Full-text available
The recognition of emotional body movement (BM) is impaired in individuals with Autistic Spectrum Disorder ASD, yet it is not clear whether the difficulty is related to the encoding of body motion, emotions, or both. Besides, BM recognition has been traditionally studied using point-light displays stimuli (PLDs) and is still underexplored in indivi...
Article
Mental imagery can be depictive or propositional and it has been linked to aesthetic preferences in literature and visual art, but little is known about their interaction with face perception. This study used a 5-points rating scale to examine if aesthetic preferences for a set of Picasso’s paintings and photographs from assorted artists were modul...

The role of distinct cortical regions in guiding social orienting needs further investigation. Our aim was to explore the contribution of the frontal eye field (FEF) in early orienting of attention towards stimuli with social value. We used a TMS-EEG approach to investigate event related potentials (ERPs; no-TMS block) and TMS evoked potentials (TE...

Abstract Background: The Modified Valence Hypothesis (MVH) posits that emotional encoding of facial expressions requires early and holistic (global or configural) processing mainly engaging the right hemisphere. There is evidence that the inferior frontal gyrus belongs to an emotional empathy circuit that operates on emotional processing and soci...
Article
Full-text available
In two experiments we investigated whether stimuli that elicit automatic orienting of attention (i.e., arrow or averted gaze) could drive apparent motion perception in one of two possible directions, modulating the effect of a low-level property (the orientation of elements along the motion direction). To this end, the competing motion paradigm was...

Infographics are a common visual means to inform users. This paper investigates how lay people of different age, gender and educational background perceive the use of infographics for information visualization in daily tasks. We chose three topics of general interest: weather, study and work, and three infographics, one for each topic. We administe...

According to both experimental research and common sense, classical music is a better fit for figurative art than jazz. We hypothesize that similar fits may reflect underlying crossmodal structural similarities between music and painting genres. We present two preliminary studies aimed at addressing our hypothesis. Experiment 1 tested the goodness...

The ability of individuals to understand other people as beings who have intentional and mental states is fundamental to adapt to our social world. To this end, our perceptual and neural systems have evolved to extract useful information from faces and moving bodies of other humans to allow reciprocal social interactions and communication.

Motor resonance (MR) involves the activation of matching motor representations while observing others' actions. Recent research has shown that such a phenomenon is likely to be influenced by higher order variables such as social factors (e.g., ethnic group membership). The present study investigates whether and how the perception of a social threat...

Cuts between different focal lengths (such as transitions from long-shot to close-up) are widely used in video editing. The question is still open whether and how cuts alter the perception of temporal continuity. To investigate this issue, two experiments were carried out, with animations representing Michotte-type launch and entraining effects as...

Background: The moving human body is a nuance-rich cue of others’ attitude: patients with Autism Spectrum Disorder (ASD) often fail to figure out its meaning and show anomalous pattern of brain activation during motion perception. Besides, their ability to recognize emotion is generally impaired, especially when conveyed by biological elements – mo...

Adaptive adjustments of strategies are needed to optimize behavior in a dynamic and uncertain world. A key function in implementing flexible behavior and exerting self-control is represented by the ability to stop the execution of an action when it is no longer appropriate for the environmental requests. Importantly, stimuli in our environment are...

Although a visual illusion is often viewed as an amusing trick, for the vision scientist it is a question that demands an answer, which leads to even more questioning. All researchers hold their own chain of questions, the links of which depend on the very theory they adhere to. Perceptual theories are devoted to answering questions concerning sens...

An experiment is presented, aimed at preliminary testing the hypothesis according to which facial expressions related to specific emotions, such as anger, fear, and joy, incorporate a sense of dynamicity and are used to enhance the representation of motion in static artworks. Since a growing body of evidence shows that motion is one of the core com...
Conference Paper
Full-text available
Three experiments are presented, aimed at testing the impact of emotional facial expressions (EFEs) on perceived dynamicity in figurative artworks. Our working hypothesis, tested in a preliminary study (Actis-Grosso & Zavagno, 2013), is that emotional faces portrayed in pictures may convey information about implied motion and therefore may contribut...

Gaze-following behaviour is considered crucial for social interactions which are influenced by social similarity. We investigated whether the degree of similarity, as indicated by the perceived age of another person, can modulate gaze following. Participants of three different age-groups (18-25; 35-45; over 65) performed an eye movement (a saccade)...

Full-text available
Our daily experience shows that the CNS is a highly efficient machine to predict the effect of actions into the future; are we so efficient also in reconstructing the past of an action? Previous studies demonstrated we are more effective in extrapolating the final position of a stimulus moving according to biological kinematic laws. Here we address...
Conference Paper
Full-text available
Background / Purpose: Human ability to extrapolate the final position of a moving target is improved (i.e. more accurate and precise) when the target moves according to biological kinematic laws (Posso et al 2006 (1)). The ability to predict the future state of a moving object is essential for programming successful actions, and has been interpre...

In the classical Poggendorff illusion, a rectangular surface partially occludes an oblique line, and it lead to perceive as misaligned the two ends of the line segment, when, in fact, they are aligned. The illusion persists when the obscuring rectangle is replaced by Kanizsa-like subjective contours (Tibber et al. 2008) and when both the rectangle...
Conference Paper
Full-text available
In the classical version of the Poggendorff illusion the two ends of a straight line segment passing behind an obscuring rectangle appear offset when, in fact, they are aligned. Previous research (Tibber et al., 2008) showed that the illusion persists when the obscuring rectangle is replaced by Kanizsa-like subjective contours. Spoto et al. (2008)...
Article
The flash-lag effect (FLE) consists in perceiving a briefly presented stationary stimulus to lag behind an aligned moving stimulus. This study investigates the effects of actively controlling the moving stimulus. By means of a robotic arm, observers continuously moved a dot along a circular trajectory, and a flash was displayed closely at unpredict...
Article
  Individuals make localization errors when asked to localize the perceived onset (starting point; SP) and offset (vanishing point; VP) of a moving target. For VP, a position shifted forward is usually indicated, whereas for SP two conflicting spatial mislocations are reported (i.e., one in the direction of motion and the other in the direction opp...
Conference Paper
Full-text available
When observers are asked to localize the starting point (SP) of a moving target, the perceived position is reported both in and opposite to the direction of motion. It is still not clear under which conditions the perceived SP is mislocalized back or forth. Although research has shown a remarkable inter-individual variability, only few studies ment...
Article
By means of a careful search we found several representations of dynamic contents of events that show how the depiction of the passage of time in the visual arts has evolved gradually through a series of modifications and adaptations. The general hypothesis we started to investigate is that the evolution of the representation of the time course in...
Conference Paper
Deviations of the judged from the actual moving target onset (starting point, SP) have been reported both in- and opposite to- the direction of motion, but it is still not clear under which conditions the perceived SP is mislocalized back or forth. To solve this ambiguity we changed the typical experimental paradigm to obtain an estimation of SP as...

Simultaneous lightness contrast is stronger when the dark and light backgrounds of the classic display (where one of the targets is an increment and the other is a decrement) are replaced by articulated fields of equivalent average luminances. Although routinely attributed to articulation per se, this effect may simply result from the increase in h...
Conference Paper
Observers make localization errors when asked to localize the perceived onset (starting point, SP) and offset (vanishing point, VP) of a moving target. Four experiments are presented, aimed to test the influence on SP and VP errors of the modulation of target’s velocity in the first- (Experiment 1) and the last-part (Experiment 2) of a 12.5° path....
Conference Paper
Judgements of moving target position are typically displaced for both onset (starting point, SP) and offset (vanishing point, VP) localization. For VP, participants usually indicate a position shifted forward, whereas for SP two conflicting spatial mislocations are reported (i.e., one in the direction of motion and the other in the direction opposi...

Full-text available
Participants asked to judge the final position of a moving target typically indicate a position shifted forward. In the 6 experiments reported here, participants were asked to indicate both the starting position (SP) and the vanishing position (VP) at the onset and offset of a moving target. Results confirmed the forward displacement of the VP and...

Curvature and velocity of human movements covary in a way described by an empirical relation known as the Two-Thirds Power Law. The visual system is particularly sensitive to this covariation, suggesting that this motor rule implicitly constrains perception. By using a visual extrapolation task, we investigated whether motion imagery is constrained...

In this paper we demonstrate the existence of simultaneous lightness contrast in displays in which the target patches are both more luminant than their surrounds. These effects are not predicted by theories of lightness that assume that the highest luminance in a scene is perceived as white, and anchors all the other luminances. We show that the st...

A grey patch set against a dark background looks lighter than an identical grey patch set against a light background. Typically, the grey of the patches is more luminant than the dark background, and less luminant than the light background. A weaker effect also obtains when the two target greys are both less luminant than their backgrounds. Yet, no...

The phenomenon studied is the perception of well known structures, the elements of which are moving in the visual field and only briefly join together. Consider a horizontal bar traveling along the equator of the screen, and a capital letter F placed in the middle of the screen, with its foot in contact with the trajectory of the bar. There is a mo...
