Participants read sentences containing high- or low-frequency target words under normal reading conditions disappearing-text (in which the word that was fixated disappeared after 60 ms). Even though had ms, there still a robust frequency effect wherein readers longer on than high-frequency words. Thus, results are consistent with cognitive-control models of eye movement control and inconsistent visual/oculomotor-control models. Although uptake visual information is clearly important for...

Immersive technologies, such as Virtual Reality (VR), have great potential for enhancing users' emotions and wellbeing. However, how immersion, Environment contents, sense of presence (SoP) influence emotional responses remains to be clarified efficiently foster positive emotions. Consequently, a total 26 participants (16 women, 10 men, 22.73 ± 2.69 years old) were exposed 360-degree videos natural social contents on both highly immersive Head-Mounted Display low computer screen. Subjective...

Understanding the influence of emotions on social interactions is important for a global understanding dynamics human behavior. In this study, we investigated interplay between emotions, spontaneous approach or avoidance tendencies, and regulation interpersonal distance. Fifty-seven healthy adults participated in three-part experiment involving exposure to approaching withdrawing emotional faces (neutral, happy, sad, fearful, disgusted, angry). The sequence began with an initial computerized...

Hemispheric specialization in saccadic control is still under debate. Here we examine the latency, gain, and peak velocity of reactive voluntary leftward rightward saccades to assess respective roles eye hand dominance.Participants with contrasting dominance were asked make toward a target displayed at 5°, 10°, or 15° left right central fixation point. In separate sessions, elicited by Gap-200, Gap-0, Overlap-600, Antisaccade procedures.Left-right asymmetries not found saccade latencies but...

In recent years, an increased demand for improving mental health and well-being led to developing procedures capable of enhancing positive experiences. One highly attractive candidate evoking experiences is Virtual Reality (VR), as VR enables users experience various situations in controlled safe environments. This overview first investigates how emotions, are interconnected. Then, about why induce emotions adult provided. Methodological ethical considerations technology, measurements VR’s...

In the antisaccade task, subjects must execute an eye movement away from a visual target. Correctly executing requires inhibiting prosaccade toward target and programming to opposite side. This could be based on inversion of vector, corresponding distance between fixation point target, or motor vector unwanted prosaccade. We dissociated two vectors by means saccadic adaptation. Adaptation can observed when systematic targeting errors are caused displacement during saccade. progressively...

Neuroimaging studies have shown that the dominant eye is linked preferentially to ipsilateral primary visual cortex. However, its role in perception still misunderstood. We examined influence of dominance and strength on saccadic parameters, contrasting stimulations presented two hemifields.Participants with contrasted (left or right) (strong weak) were asked make a saccade toward target displayed at 5° 7° left right fixation cross. In some trials, distractor 3° eccentricity also was either...

Previous studies have demonstrated a left perceptual bias while looking at faces, due to the fact that observers mainly use information from side of face (from observer's point view) perform judgment task. Such is consistent with right hemisphere dominance for processing and has sometimes been linked gaze bias, i.e. more and/or longer fixations on face. Here, we recorded eye-movements, in two different experiments during gender task, using normal chimeric faces which were presented above,...

Abstract Age-related changes in emotional processing are complex, with a bias toward positive information. However, the impact of aging on responses everyday situations remains unclear. Virtual Reality (VR) has emerged as promising tool for investigating processing, offering unique balance between ecological validity and experimental control. Yet, limited evidence exists regarding its efficacy to elicit emotions older adults. Our study aimed explore age-related differences immersion both...

It is well known that the saccadic system presents multiple asymmetries. Notably, temporal (as opposed to nasal) saccades, centripetal centrifugal) saccades (i.e., recentering bias) and from abducting eye concomitant adducting eye) exhibit higher peak velocities. However, these naso-temporal centripetal-centrifugal asymmetries have always been studied separately. thus unknown which asymmetry prevails when there a conflict between both asymmetries, i.e., in case of nasal or centrifugal...

In the temporal vicinity of a saccade onset, visual stability is transiently disrupted and briefly flashed stimuli undergo systematic perceptual mislocalization. Specifically, when stimulus around localization judgments are grossly biased toward endpoint. This peri-saccadic compression increases with amplitude. Previous studies have typically used rather large amplitudes. present study, we investigate systematically pattern errors for small sizes (2°-10°), taking into account both amplitude...

Around the onset of a saccade toward target, localization judgments are systematically biased endpoint. This perisaccadic compression is thought to be related transsaccadic reorganization and due interfering motor signals in visual maps. It has, however, only been investigated for saccades targeting single target. Here, we examined whether saccade-sequence programming stationary target(s) would affect pattern briefly flashed stimulus. We presented targets that could induce either or...

To compare the amount, retention, and extinction of saccadic adaptation in two groups: 9 adults (23-36 years old) children (11-14 old).The paradigm used was a classical double-step target to elicit shortening saccade gains response 2° backward step (20% eccentricity). Two conditions were run pre- postadaptation phases without with postsaccadic visual feedback, allow examination retention adaptation.Adaptation reactive saccades occurred as well adults. Both groups showed progressive amplitude...
