The visual system in object recognition
Iconic memory or visual sensory memory
captures an image of a visual stimulus for a brief period of time after the stimulus stops happening
What is the template theory?
Template theory is when your visual system compares a stimulus with a set of templates stored in your memory.
What is change blindness?
we fail to detect a change in an object or scene.
What is perception?
Perception uses previous knowledge to gather and interpret the stimuli registered by the senses.
What is illusory contours (subjective contours)?
is when we see edges even though they are not physically present in the stimulus.
Where is the primary visual cortex located and what is it responsible for?
It is located in the occipital lobe of the brain, and it is responsible for the basic processing of visual stimuli
What is Feature analysis theory?
we recognize objects by breaking them down into basic features and then putting those features together.
Inattentional blindness is when
we fail to notice a visible object or event because your attention is focused on something else.
What is Object recognition/Pattern recognition?
It is the brain's ability to identify and understand what an object is based on the visual information it receives.
Figure-ground relationship
Is when your visual perception, you can clearly see the figure as the main subject and the ground as the background, you can see them as seperate.
What is distal stimulus?
The actual object that is "out there" in the environment, for example, the pen on your desk.
_________ demonstrated a study that people require a relatively long time to decide whether one letter is different from a second letter when those two letters share a large number of critical features which is also an example of feature analysis.
Eleanor Gibson
People with ______ cannot recognize human faces, though they recognize other objects normally.
Prosopagnosia
In an ambigious figure ground relationship,
the figure and the ground reverse from time to time so that the figure becomes the ground and then becomes the figure again.
What is the proximal stimulus?
Is the information registered on your sensory receptors (cells that help your senses pick up information from the world) for example, the image that your pen creates on your retina.
______ and his colleagues developed a theory to explain how humans recognize three-dimensional shapes
Irving Biederman
Research shows that people are much more accurate in identifying upright faces compared to upside down faces, this phenomenon is called the
Face- inversion effect
What is sensory memory?
a large-capacity storage system that records information from each of the senses with reasonable accuracy.
The ________ is that a specific view of an object can be represented as an arrangement of simple 3-D shapes called _____, it can also be combined to form meaningful objects and young children can only see shapes but older children and adults can see ____
Recognition-by-components theory, Geons, geons
Viewer centered approach
is when we see an object from an unusual angle, and this object does not match any object shape stored in memory, we then mentally rotate the image of that object until it matches one of the views that are stored in memory.
