This camera eye’s view shows 
how a scene appears to subjects 
wearing an inverting optical 
device when they tilt their 
heads slightly.

    What, then, does Stratton’s 
experiment demonstrate about 
upright vision? We can grant 
that sensory-motor 
coordination can adapt to 
inverted images and that 
tactual and proprioceptive 
perception are sufficiently 
malleable that these sensations 
will, with time, be "captured" 
by vision, thus abolishing the 
intersensory disharmony that 
occurs at the outset. We also 
can grant that the optically 
altered scene will become 
increasingly "normal" in 
appearance and that the 
environmental scene can 
ultimately appear upright with 
respect to gravity, but still not 
necessarily grant that a change 
in perceived egocentric 
orientation occurred. My own 
reading of Stratton’s report is 
that the scene continued to 
appear upside down in relation 
to himself (or at least to his 
head) throughout the 
experiment.

    Consider this report of the 
last day of the experiment:

       As long as the new 
    localization of my body was 
    vivid, the general experience 
    was harmonious, and 
    everything was right side up. 
    But when, for any of the 
    reasons already given—–an 
    involuntary lapse into the 
    older memory-materials, or a 
    willful recall of these older 
    forms—–the pre-experimental 
    localization of my body was 
    prominently in mind, then as I 
    looked out on the scene before 
    me, the scene was 
    involuntarily taken as the 
    standard of right directions, 
    and my body was felt to be in an 
    inharmonious position with 
    reference to the rest. I seemed 
    to be viewing the scene from an 
    inverted body.
