Illusory


Definition:

  • (a.) Deceiving, or tending of deceive; fallacious; illusive; as, illusory promises or hopes.

Example Sentences:

  • (1) Enhancement of the VEP of the illusory figure stimuli was observed for a specific component (N2), whereas the amplitude values at the central components and the occipital P120 (P2) and P280 (P3) were almost the same as the reference values.
  • (2) If a segment of a line differs in luminance or color from the rest of the line, three illusory phenomena may be perceived: a reduction in contrast of the line segment relative to the background, subjective contours running perpendicularly to the ends of the line segment, and spread of color or brightness surrounding the line segment.
  • (3) However, in free fall even without head tilts there was a significant suppression of nystagmus relative to 1 G and 1.8 G force backgrounds, thus potentially masking an effect of head tilt on suppression in 0 G. We have retested four of the original subjects with 90 degrees head tilts to maximize the likelihood of detecting suppression in 0 G. Although nystagmus and illusory after-rotation were suppressed by post-rotary head tilts in normal and high gravitoinertial force environments, there was still no evidence of suppression in free fall.
