VISUAL ATTENTION
Visual attention is the psychological process that helps us to transform chaotic visual scenes into ordered information.
We use it all the time (and especially in the hidden
objects games!)
VISUAL SEARCH
Can you find a panda?
Visual search is a process of active scanning of the visual environment for a particular object – target, among other objects – distractors.

SUBSEQUENT SEARCH
MISSES
The effect has been found in 1960 by
surgeons
Other tumors may be missed in an X-ray if
the first tumor has already been found
So surgeons found the underlying disease and missed the others
RAPID SERIAL VISUAL PRESENTATION METHOD
Is used in «Spritz» speed reading
RSVP helps to study the timing of vision
Stimulus, like numbers, letters or pictures, are
rapidly presented (15-75 milliseconds) at one location of the visual field
THE PROCEDURE
You will see a series of letters, in quick succession, with two numbers (between 1 and 9) interspersed.
Your task is to remember the SECOND number presented.
The presentation is like:
ATTENTIONAL BLINK
Discribed in 1992 by Raymond, Shapiro and Arnell
People found the first target, but they typically failed to find the second one if it appeared in 200 to 500 milliseconds to the first
T1 and T2 – targets, numbers – distractors.
1 second of the presentation,
We have to find the two targets by focusing at the center of the screen.
POSSIBLE EXPLANATIONS
One of the most famous is the limited-capacity attentional resources theory
Other explanation refers to inability to keep appropriate attentional control
or
Uncertainty and confusion of identification the targets
