Illusory Upward Self-Motion Results in a Decrease in Perceived Room Temperature
نویسندگان
چکیده
Purpose: Stationary observers often experience illusory self-motion (vection) when they are exposed to large patterns of optic flow. The effect of different temperatures on the strength of vection was investigated. Method: Eleven participants were exposed to visual stimuli that induced illusory motion (up, down) in three room temperatures (26 ̊C 27 ̊C, 21 ̊C 22 ̊C, 5 ̊C 6 ̊C). Participants rated (a) the vection magnitude, and (b) the room temperature (twice; before and after vection). Results: Upward vection was rated as stronger than downward vection in the 26 ̊C 27 ̊C temperature. In addition, after experiencing upward and downward vection, subjective ratings of room temperature decreased and increased, respectively, when the room temperature was 26 ̊C 27 ̊C. This effect was not observed when the room was 5 ̊C 6 ̊C. Conclusion: These results suggest that a cross modal association exists between the direction “up” and 26 ̊C 27 ̊C temperatures.

Illusory scene distortion occurs during perceived self-rotation in roll
We report a novel illusory distortion of the visual scene, which became apparent during both: (i) observer rotation inside a furnished stationary room; and (ii) room rotation about the stationary observer. While this distortion had several manifestations, the most common experience was that scenery near fixation appeared to sometimes lead and other times lag more peripheral scenery. Across a se...
متن کاملInfluence of Visual Motion, Suggestion, and Illusory Motion on Self-Motion Perception in the Horizontal Plane
A moving visual field can induce the feeling of self-motion or vection. Illusory motion from static repeated asymmetric patterns creates a compelling visual motion stimulus, but it is unclear if such illusory motion can induce a feeling of self-motion or alter self-motion perception. In these experiments, human subjects reported the perceived direction of self-motion for sway translation and ya...
متن کاملHunger enhances vertical vection.
Hunger was found to facilitate visually induced illusory upward and downward self-motions (vertical vection), but not illusory self-motion in depth (vection in depth). We propose that the origin of this hunger effect lies in the possibility that vertical self-motions (both real and illusory) are more likely to induce changes in visceral state.
متن کاملAnomalous Motion Illusion Contributes to Visual Preference
This study investigated the relationship between the magnitude of illusory motion in the variants of the "Rotating Snakes" pattern and the visual preference among such patterns. In Experiment 1 we manipulated the outer contour and the internal geometrical structure of the figure to test for corresponding modulations in the perceived illusion magnitude. The strength of illusory motion was estima...
متن کاملIllusory Motion and Mislocalization of Temporally Offset Target in Apparent Motion Display
When a visual target briefly appears in a display containing visual motion information, the perceived position of the target is mislocalized forward along its direction of motion. This phenomenon is assumed to be caused by the interaction between the transient onset signal of the target and motion information. However, while transient onset and offset signals are important for the establishment...
