“…This agreement extends to the results of E. L. Smith et al (1982). Their Figure 1 shows that spectral sensitivity during suppression is less than that during dominance and that there is no clear dependence of suppression depth on stimulus wavelength at wavelengths above 480 nm.…”

“…These data were obtained by dividing contrast threshold during dominance by that during suppression, and the loss owing to suppression is represented by the displacement of an ordinate below the dashed line. If chromatic channels were more suppressed than luminance channels, as was suggested by E. L. Smith et al (1982), suppression depth would be greater at azimuths close to 135º and 315º, where the test stimulus is isoluminant with the background. There is a suggestion of such a trend in the data from subject D.L., but no such trend is evident for the other subjects.…”

“…E. L. Smith et al concluded that signals in chromatic visual channels are reduced more than those in luminance channels during suppression. E. L. Smith et al's (1982) result suggests a possible reason for the discrepancy between large perceptual losses and small sensitivity losses during binocular rivalry. Perhaps the perceptual loss during rivalry is due to the reduced signal in chromatic channels, whereas the detection of a test stimulus during suppression is mediated by the relatively unaffected luminance channels.…”

Binocular rivalry occurs when the two eyes are presented with incompatible stimuli and the perceived image alternates between the two stimuli. The aim of this study was to find out whether the periodic perceptual loss of a monocular stimulus during binocular rivalry is mirrored by a comparable loss of contrast sensitivity. We presented brief test stimuli to one eye while its conditioning stimulus was dominant or suppressed. The test stimuli were varied widely across four stimulus domainsnamely, the relative stimulation of medium-and long-wavelength-sensitive cones, duration, spatial frequency, and grating orientation. The result in each case was the same. Suppression depended slightly or not at all on the type of test stimulus, and contrast sensitivity during suppression was around 64% of that during dominance. The effect of suppression on sensitivity is therefore very weak, relative to its effect on the perceived image. Furthermore, suppression was largely independent of the similarity between the conditioning and the test stimuli, indicating that our results are better explained by eye suppression than by stimulus suppression. A model is presented to account for the small, monocular sensitivity loss during suppression: It assumes that test detection precedes conditioning stimulus perception in the visual pathway.

“…The chromatic pathways appear to be more affected by rivalry suppression than the achromatic pathway 42 . Moreover, Julesz & Miller 43 showed that binocular rivalry and binocular fusion may occur simultaneously within different spatial frequency bands.…”

SUPPLEMENTARY NOTESThis paper was originally published in SPIE Vol. 6224, Helmet-and Head-mounted Displays XI (July 2006). ABSTRACTWhen wearing a monocular head-mounted display (HMD), one eye views the HMD symbology while both eyes view an out-the-window scene. This may create interocular differences in image characteristics that could disrupt binocular vision by provoking visual suppression, thus reducing visibility of the background scene, monocular symbology, or both. However, binocular fusion of the background scene may mitigate against the occurrence of visual suppression, a hypothesis that was investigated in the present study. Observers simultaneously viewed a static background scene and HMD symbology while performing a target recognition task under several viewing conditions. In a simulated HMD condition observers binocularly viewed a background scene with monocular symbology superimposed. In another condition, viewing was dichoptic (i.e. completely different images were presented to the left and right eyes). Additionally, one control condition was implemented for comparison. The results indicate that for continuously presented targets binocular rivalry did not have significant effects on target visibility. However, for briefly presented targets, binocular rivalry was shown to increase thresholds for target recognition time in HMD and dichoptic viewing conditions relative to the control. Impairment was less in the HMD condition. Thus, binocular fusion of a background scene can partially mitigate against the occurrence of visual suppression. However, some suppression still exists which occurs between monocular pathways. Implications for the integration of monocular HMDs into Air Force training environments will be discussed.
