AI Article Synopsis

  • Illusory motion refers to the perception of movement in stationary images that have repeating light and dark patterns.
  • The study aimed to test a hypothesis that suggests our brains integrate velocity information from these patterns by summing them up.
  • Results from psychophysical experiments indicated that this summation rule accurately predicts how we perceive motion, helping to illuminate how our visual system processes local motion signals.

Article Abstract

Illusory motion is a phenomenon in which stationary images with repeating luminance gradient patterns appear to be moving. In this study, we conducted experiments focusing on illusory motion to verify the hypothetical rule that velocity information, extracted from local luminance patterns, is integrated by summation in visual information processing. This rule is based on the hypothesis of velocity integration, and could estimate perceived velocity of stimulus. The summation rule was evaluated by a psychophysical experiment. Our results showed that the summation rule unbiasedly predicted perceived velocity, suggesting that an algorithm for integrating velocity information in illusory motion is based on the summation rule. These results would contribute to understanding of the spatial integration of local motion signals in visual information processing.

The current study sought to examine factors that affect vection (the illusory experience of self-motion in the absence of real motion), visually-induced motion sickness, and one's sense of presence in a passive virtual reality driving simulation by exposing participants to 60-s pre-recorded driving laps and recording their self-reported metrics as well as their head motion patterns during the laps. Faster virtual driving speed (average 120 mph vs. 60 mph) resulted in significantly higher ratings of vection and motion sickness.

Visual perceptual learning plays a crucial role in shaping our understanding of how the human brain integrates visual cues to construct coherent perceptual experiences. The visual system is continually challenged to integrate a multitude of visual cues, including form and motion, to create a unified representation of the surrounding visual scene. This process involves both the processing of local signals and their integration into a coherent global percept.

Article Synopsis
  • Visual illusions are systematic misperceptions that reveal how our brains construct visual experiences, with the "frame effect" being a notable example where moving frames mislead our perception of an object's position.
  • A newly identified illusion, the "split stimulus effect," shows that symmetrical motion of overlaid frames can cause observers to perceive two instances of a single stimulus, as evidenced by participants sometimes reporting two dots when only one was shown.
  • This study also explored factors influencing the illusion, such as frame speed and spatial attention, and demonstrated that individuals can hold conflicting perceptual predictions about the same object, shedding light on the underlying mechanisms of visual perception.

We explored in 75 s long trials the effects of visually induced self-rotation and displacement (SR&D) on the horizontally extended right arm of standing subjects (N = 12). A "tool condition" was included in which subjects held a long rod. The extent of arm movement was contingent on whether the arm was extended out Freely or Pointing at a briefly proprioceptively specified target position.

We showed to the same observers both dynamic and static 2D patterns that can both evoke distinctive perceptions of motion or optic flow, as if moving in a tunnel or into a dark hole. At all times pupil diameters were monitored with an infrared eye tracker. We found a converging set of results indicating stronger pupil dilations to expansive growth of shapes or optic flows evoking a forward motion into a dark tunnel.
