Interference Effect.

Interference Effect

Interference effect- a "competition" between mental processes. It occurs when two or more perceptual or cognitive processes are in conflict. Because human perception and cognition analyze and process information independant of one another, the output of these systems should be congruent. However, if they are incongruent, then additional time and process will be required in order to resolve the conflict.

Interference effects of perception:

• Stroop interference- a result from conflicting code combinations.
  
• Garner interference-a result from an interaction between closely placed objects that visually interact with one another.

Interference effects of cognition:

• Proactive interference-existing memories interfere with learning.
• Retroactive interference-learning interferes with existing memories.
