What Are The Theories Behind This Worksheet?

Filtering, commonly known as Mental Filters, is one of the cognitive distortions whereby people tend to focus on one aspect of a situation: usually the negative side/ negative information/ negative details.

People who battle mental filtering often tend to magnify the negative side of a situation while filtering out the positives.

Many psychologists have found a strong link between focusing on negative details with depression, anxiety, and self-esteem. Research shows that there is a cognitive bias for dwelling on one’s shortcomings that can lead to fixating on negative feedback. (NESS LABS, no date)

Mental filtering can also have a detrimental impact on our self-confidence and personal growth. In order to manage this cognitive distortion, one has to learn to subconsciously manage negative thought patterns and begin to see their efforts and hard work in a more positive outlook.
