    Attention • Some aspects of our perception are under our  conscious attentive control. • Example:  In a large crowd, we can concentrate on  listening to some people and ignoring others. • However, other perceptual processes occur  automatically and we cannot consciously control  them.

    Automatic Processes: The Stroop Effect • Some abilities which once required attention  can become automatic through practice. • An example of such learned automaticity is  found in the Stroop Interference Effect. • Stroop found that the act of reading could  interfere with your ability to perform simple  perceptual distinctions like naming colors.

    The Stroop Effect • For adults, reading has become such an automatized  process that it is very difficult to turn off.  Thus, it can  cause errors when what you’re reading conflicts with  what you’re trying to attend to.   • Automatic processes occur even when you try to over- ride them.
