Interference Effect
- ‘ a phenomenon in which mental processing is made slower and less accurate by competing mental processes ‘
- occur when two or more perceptual or cognitive processes are in conflict.
- There are 4 type of interference effect:
- Stroop interference
- Aspect that irrelevant stimulus that triggers a mental process that interferes with the processes involved in stimulus-related aspect.
- When the name of colour printed is not match with the colour, naming the colour of the word will take longer time. For example, the green colour is paint to the word “yellow”.
2.Garner interference
- An irrelevant variation of a stimulus triggers a mental process involving a relevant aspect of the stimulus.
- For example, naming the column of shapes which stand alone is easier and quicker than naming either of the columns located together.
3. Proactive interference
- Occurs when two similar information (current & previous information) mixed up.
- We know that red mean stop and green refer to go, but we can see that image below creates interference.
4.Retroactive interference
- Happens when learning interferes with existing memories.
- For example, we know that traffic arrow means go and red colour mean stop, then a red arrow in a new traffic light can make very dangerous interference and confusion.
