Research into Visual Perception conducted by Dickinson
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.
Dickinson undertook a series of detailed experiments into ‘Experience
and Visual Perception’ using stimuli consisting of arrangements
of letters (alphabetic characters) and playing cards.
C.A.Dickinson, "Experience and visual perception", Am.J.Psychol.,
Vol.37, pp.330-344 (1926). His account demonstrated that there
are three levels of human visual perception, which were termed: visual pattern, generic
object and specific object.
Dickinson did
not consider these three levels to be separate and distinct, but
progressive in nature - one
level developing into another. His 1926 paper is among the earliest
accounts to distinguish between three levels of perception broadly
corresponding to the modern definitions of detection, recognition and
identification
(terminology also important in the field of "Human Factors", as used
to develop improved instrumentation and other devices that incorporate
visual interfaces).
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).
