4. Overanalyzing rejection
Our brain is like a computer processor: It has a finite amount of processing power, or intellectual resources, that can be used in a given moment. Any competing task (or emotional state) that occupies too much of our intellectual firepower impacts our ability to concentrate, focus, problem-solve, be creative, or use other cognitive abilities; as a result, our functioning IQ is temporarily lowered.
To demonstrate this principle, try walking while counting down from 1000 by sevens (1000, 993, 986, etc.). You will soon stop walking. Why? Your brain has to work so hard to do this math that it doesn’t have enough resources left to tell your legs to put one foot in front of the other.
Most common competing tasks do not have a significant impact on our ability to work or study. Most of us can do homework while listening to music and can become absorbed in a book while eating.
However, some psychological habits consume such huge amounts of intellectual resources that they diminish our cognitive capacities. Few people are aware that these psychological habits have such a detrimental effect, so they are unlikely to pause what they’re doing—and this can seriously affect a person’s ability to perform a task at full capacity.
5 Common Psychological Habits that Impair Intellectual Functioning
Replaying upsetting, frustrating, or distressing events over and over again—especially when doing so frequently or habitually—can make our minds race with thoughts or stir us up emotionally, severely taxing our intellectual resources. In addition to impacting our cognitive functioning, brooding (also known as ruminating) can present real dangers to our emotional and even our physical health. (See The Seven Hidden Dangers of Brooding.)
2. Unresolved Guilt
We all feel guilty from time to time. When we do, we typically apologize or take some kind of action to resolve our guilty feelings. However, when guilt is not addressed and repeatedly pops into your mind, it creates a huge cognitive distraction that seriously impairs cognitive functioning. The solution is to put guilty feelings behind you as best you can. (See The Secret of Effective Apologies.)
3. Ineffective Complaining
Most people are likely to share their frustrations with friends than discuss them with someone who could help to resolve them. The problem is that, each time we tell our tale, we become frustrated and annoyed. Anger and frustration require significant processing power and enable ineffective complaints to become a regular drain on our brainpower.
4. Overanalyzing Rejection
Rejection creates emotional pain that significantly impacts our mood and has a serious impact on cognitive functioning. It also causes us to become self-critical, a habit that further damages our self-esteem, extending the duration of our emotional distress—and with it, our compromised cognitive abilities. (See 10 Surprising Facts about Rejection.)
Many people don’t consider worrying harmful. “I’m just a bit of a worrier,” we might say with a wry smile. But worrying creates an uncomfortable and unpleasant emotional state, and it can be seriously distracting. When we’re worried about something, it tends to take priority in our minds, and push everything else to the side. Fortunately, it’s easier to address and resolve worry (by thinking through potential solutions) than it is anxiety. (See The Difference between Anxiety and Worry.)
