NCIDQ IDFX COMPREHENSIVE EXAM 2026
QUESTIONS WITH SOLUTIONS GRADED A+
◉ Theory. Answer: The most fundamental beginning of design.
◉ Design History. Answer: A valuable contribution to design theory by
suggesting how past designs solved certain problems or represented
particular ideal.
◉ Environmental Design. Answer: A theory that focuses on the
interaction between humans and their environments that attempts to
develop a rational design approach based on scientific research rather
than anecdotal evidence or personal philosophy. Often does not take into
account the interaction between humans and buildings.
◉ Evidence Based Design. Answer: Basing design in credible research
that links one or more environmental elements with a desired outcome.
Often used in healthcare but has been applied to education and
workplace design.
◉ Functionalism. Answer: A simple rational design solution to design
problems without extraneous decoration. Reduced interiors to only what
was required to meet strict functional needs without unnecessary
decorations.
,◉ Le Corbusier. Answer: A house is a machine for the living
◉ Gestalt Pyschology. Answer: a psychological approach that
emphasizes that we often perceive the whole rather than the sum of the
parts
◉ Simultaneous Constrast. Answer: a phenomenon in which a color
appears to change depending on the background color.
◉ Grouping. Answer: humans perceive separate units in the visual field
as a group, through proximity, similarity, direction, and context
◉ Closure (form constancy). Answer: the tendency to perceive
incomplete forms as a whole
◉ Continuity. Answer: the tendency to see a line or shape as continuing
in a particular direction rather than making a sharp turn.
◉ Simplicity. Answer: humans prefer the simplest, most stable
organization of forms. the brain organizes forms into the fewest number
of lines or parts.
◉ Figure-ground. Answer: the was form (figure) is distinguished from
surroundings (ground)
,◉ Perceptual Constancy. Answer: perceiving objects as unchanging
(having consistent lightness, color, shape, and size) even as illumination
and retinal images change
◉ Shape Constancy. Answer: the perception of objects as having their
original shape regardless of change in orientation or point of view.
◉ Size Constancy. Answer: the perception of objects having the same
size regardless of viewing distance.
◉ Lightness Constancy. Answer: the perception of objects to have the
same lightness or darkness regardless of the illumination of the space in
which it is viewed
◉ Color Constancy. Answer: the perception of an objects color as the
same regardless of the lighting conditions
◉ Binocular Disparity. Answer: the difference in the retinal images of
the left and right eye which allows the viewer to perceive distance and
three-dimensions
◉ Interposition. Answer: a distant object may appear to be overlapped or
partly hidden by a closer object
, ◉ Linear Perspective. Answer: parallel lines appear to recede toward a
single point in the distance
◉ Atmosphere Perspective. Answer: haziness of an object that increases
with distance caused by small particles in the air
◉ Texture Perspective. Answer: the density of a texture seems to
increases as the distance for the viewer increases.
◉ Size Clues. Answer: when wo objects are the same size but the further
one will make a smaller image on the retina than the closer
◉ Horizon Line Relationship. Answer: the closer an object is to the
horizon line the further away it is.
◉ Cue Inconsistency. Answer: visual cue inconsistencies such as an
unpleasant smell in a restaurant or echoes in a small intimate space
◉ Political conditions. Answer: A social and cultural belief that
influence interior design through political thought that creates awareness
to a design ideal
◉ Economic Conditions. Answer: A social and cultural belief that
influence interior design through the economic growth at the time.
