An example of when task-irrelevant stimuli are difficult to ignore. It occurs when you are tasked with saying the color of different words  when the words are also colored. For example, the word blue might be colored red, or the word yellow might be colored green. The conflict between the word and its coloration causes difficulty when determining the color.

Attentional capacity

Selective attention is the psychological process of focusing on a specific subset of available sensory information while ignoring other distracting stimuli. Because it acts as a filter for incoming sensory data, selective attention helps explain why some environmental stimuli are consciously perceived and others are not.

Selective Attention

Distractions

Paying attention to more than one thing at a time. In a sense attention is being divided among different stimuli.

Divided attention

When the focus of someone's attention quickly changes, often due to some significant stimuli (i.e. loud noise, bright light, etc)

Attentional capture

- Overt and Covert attention
- Fixation
- Saccadic eye movement
- Visual scanning

Focuses of research on eye movement

The physical properties of the stimulus, such as color, contrast or movement, that influence attention.

Stimulus salience

How features (color, motion, shape, etc.)  come together through attention to form a perception of an object.
