Research into Visual Perception conducted by Henle
From the mid-1920s to the early 1940s the influence of past experience
on human visual perception was a popular research area. Many investigators
employed arrangements of simple two-dimensional geometrical shapes,
sometimes alone and sometimes embedded in more complex forms.
Henle conducted
research into human visual perception using alphabetic characters
and their mirror reversals as the stimuli in his experiments. The results
of
this work were published in 1942:
M.Henle, "An experimental investigation of past experience as a determinant
of visual form perception",
J.Exptl.Psychol., Vol.30, pp.1-21 (1942).
Following on from previous work by Gottschaldt and Braly (among others),
Henle argued that since the effect on perception of both object shape and past
experience had
been
established,
both
these factors
must
be
recognised.
He
suggested that if an object is very familiar to the observer then
the effect of past experience may be dominant, the opposite being true
for complex,
unfamiliar objects.
This Section consists of short summaries of historial research and theories
into human visual perception of simple two-dimensional objects (these
are extracted and summarised from a Ph.D. Thesis [67] dated
1996).
