An intro to psychology about sensation and perception

1. Psychology101
Sensation
&

2. is the process that allows our
brains to take in information via
our five senses, which can then be
experienced an interpreted by the
brain.

3. can be defined as our recognition and
interpretation of sensory information.
Perception also includes how we
respond to the information.

4. Is the primary process by which we obtain
knowledge about the world we live in. it involves
the taking in of information, through the
activity of our sense organs responding to
external stimulation (Sensation), followed by the
processing of that information to make sense of
what we see, hear, smell, taste, and touch.
Perception

5. Perception
Is an active process of
extracting information
from the impingements of
energy on our sense
organs. When we
perceive we interpret,
organized, and often
elaboration on the raw
materials of sensation.

6. Short Activity
Direction:
Say a word what comes
first from your mind when
you see this picture

10. Localization
Constant
Recognition
Discerning what objects are.
Keeping the appearance of the objects, even if their
images in the eye are changing.
To locates objects or determining where objects are.
Major Functions of the Visual Perceptual System

11. Gestalt Principles of Grouping
Gestalt
- A group of influential German Psychologist
among them Max Wertheimer, Kurt Koffka and
Wolfgang Kohler. They theorized that we
perceive figures and forms as whole patterns that
are more than simple sum of individual sensation

12. Localization

13. 4 Laws of Perception

14. Depth Perception
Known as pictorial cues
because they are widely used
by artist to show three
dimensional images on a flat
surface.

15. Relative Size
If an image contains an
array of similar objects
that differ in size, we
interpret the smaller
objects as being farther
away. This phenomenon
works particularly well
when we know the true
sizes of the objects.

16. Superimposition
If one is positioned
so that it obstructs
the view of
another, we
perceive the
overlapping object
as near.

17. Relative Height
Among similar
objects, those that
appears higher are
perceived as being
farther away. The
“higher” column
perceived as farther
behind the “lower”
column.

18. Linear Perspective
When parallel
lines appear to
meet. They are
perceived as
vanishing in the
distance.

19. Motion Parallax
Refers to the
relative
movement of
objects at
different
distances from
the observers.

20. Motion Perception
Localizing an object sometimes
requires determining the movement
of objects.

21. Template Theory
When the teacher writes
letter “E” on the
blackboard, we read it as
such after comparing this
stimulus to the templates
of alphabet forms in our
memory to produce the
closest match.
Recognition

22. Prototype Theory
The theory argues
that every
member of a
particular
category shares
certain key visual
attributes.

23. Feature Theory
These features are
extracted from the
present stimulus and
combined and
compared with a
bank of such features
in permanent
memory.

24. Perceptual Constancies
Constant
Size Constancy Lightness Constancy Color Constancy

25. Shape Constancy Location Constancy

26. Last Activity
SAY the Color but
don’t READ the Color
