What's the difference between illusory and veridical?

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.
  • (4) Illusory size perception based on localization of objects in depth in such pictures nonetheless occurred.
  • (5) This remarkable tendency to estimate one's own image too thin in female schizophrenics is interpreted as an illusory approximation to an ideal image.
  • (6) These findings suggest that among a group of would-be slimmers who claim to be unable to lose weight there will be some who have become metabolically adapted to a low-energy diet and others whose inability to lose weight is illusory.
  • (7) Brown used the money to pay illusory profits to other investors and spent much of the rest on himself.
  • (8) One of the common responses to criticism of psychics is to suggest that even if their powers are illusory, there is no harm done.
  • (9) Incongruous and illusory depth cues, arising from 'interference patterns' produced by overlapping linear grids at the edges of escalator treads, may contribute to the disorientation experienced by some escalator users, which in turn may contribute to the causes of some of the many escalator accidents which occur.
  • (10) The apparent displacement was correlated with lateral heterophoria in the occluded eye, and phoria was necessary for the illusory displacement.
  • (11) A theory of perception is extended to figural after-effects which has been used already to rationalize the illusory phenomena of static visual illusions, fluctuating figures and visual illusions of motion.
  • (12) Furthermore, the disintegration of information from the neck position receptors from those of the otolith system can lead to additional illusory positional sensations.
  • (13) Illusory brightness effects are also observed in connection with the different organizations of this ambiguous figure.
  • (14) The results from Experiment 2 revealed a reversal of the effect of global goodness on the rate of illusory conjunctions: Illusory conjunctions of negative- and positive-diagonal line segments were more likely to occur in diagonal arrangements.
  • (15) It forces us to act even when so many comforts seem unaffected, and the threat so far off, if not illusory.
  • (16) The reverse sequence of illusory motion is experienced during deceleration.
  • (17) Still, there's an upside to 007's monogamy, and it may just explain how this much-maligned film has wheedled its way so irrevocably into my affections: uniquely in the world of Bond, it allows a vein of romantic adventure to develop that's real, not illusory.
  • (18) The demonstrations and experiments suggest that depth from an uncrossed disparity can be extrapolated from, not just interpolated between, illusory or real contours to form perceptually a background surface.
  • (19) When presented with such partial cues, observers report perceiving 'illusory' contours and surfaces (forms) in regions having no physical image contrast.
  • (20) Furthermore, a new demonstration is presented that indicates that interocularly-induced illusory contours 'capture' and extend the monocularly-induced local color spreading, resulting in global color spreading (neon color spreading).

Veridical


Definition:

  • (a.) Truth-telling; truthful; veracious.

Example Sentences:

  • (1) We studied how much blue, green, or red light had to be added to or subtracted from white to obtain veridical hue perception (blue, green, red, or their complementary colours) at various locations in the temporal visual field.
  • (2) This rotation is believed to pose a problem with veridical stereoscopic localization.
  • (3) It is controversial whether or not veridical feedback is necessary to bring about increases in alpha activity in the feedback situation and has been suggested that the instructional variable may be a crucial determinant of outcome.
  • (4) What happens to the timing of the grasp movements involved in catching a ball when optical expansion information is not veridically provided?
  • (5) In light of these two qualitatively different deficits, possible mechanisms are discussed how the two signals may interact towards a more veridical visual localization.
  • (6) When room reflectance was high (T60 approximately 1.7 s for the range of frequencies used), initial reports of distance were often overestimates; upon repeated presentation, judgments in the high reflectance room became more nearly veridical.
  • (7) However, in the presence of colour contrast, significantly higher levels of luminance contrast are required to achieve a veridical velocity than for monochromatic stimuli with only luminance contrast.
  • (8) If fear faces are functionally analogous to prepared stimuli, then, even in the absence of veridical support for an expectation of shock, they should retain excitatory strength, whereas happy faces should not.
  • (9) Phenomenal geometry is expected to apply to both veridical and illusory perceptions.
  • (10) Once distorted, return to veridical attitude perception can be gradual because, in the absence of complimentary canal or visual information, recovery is dependent upon relatively slow cognitive appreciation of a prevailing otolith position signal.
  • (11) However, there was one noticeable exception; during the combination 'head rotation on stationary trunk', Ss veridically perceived their trunk as stationary (compatible with the notion that the sum yielded 'zero').
  • (12) This study was designed to determine whether veridical interpersonal perceptions can be found on the basis of physiognomic cues.
  • (13) Results demonstrated considerable veridicality, especially by male judges and of stimulus persons occupying categories which imply physical attributes.
  • (14) This lack of correlation suggests that the responses obtained when viewing either the DOG target or retinoscope beam may not represent a veridical measure of TA.
  • (15) From published data it has been possible to calculate the magnitude of the vertical disparities that the human visual system must be able to discriminate in order for depth constancy to have the observed level of veridicality.
  • (16) Perceptual content is how the external intentional object perspectivally appears from moment to moment and how it is perceptually taken to be, veridically or not.
  • (17) The obtained data indicate that increasing the availability of binocular disparity by increasing viewing screen width favors veridical rotation perception.
  • (18) Regardless of hand used, right-handers bisected vertical lines significantly above veridical center.
  • (19) This report examines the accuracy or veridicality of information obtained through interviews with drug addicts.
  • (20) The CIE 1931 (x, y) chromaticity coordinates corresponding to a veridical hue perception were subtracted from the chromaticity coordinates of the white (0.35, 0.35) in order to obtain the threshold differences (dx, dy) in chromaticity coordinates.
