Positive thinking can feel like a job to do, while negative thinking seems to happen more automatically. In fact, this is true at a very fundamental level of the brain, studies show. It is called the negativity bias.
The human brain is sophisticated. In fact, it separates us from all other animals. It allows us to have abstract ideas and to solve complex problems. We are rational social beings, or are we?
Brain training is a hot topic. It’s a million-dollar business and its popularity is still increasing. We have been interested in increasing people’s intelligence since the study of intelligence, but computerized brain training is a relatively new invention.
A number of studies have examined how stress affects learning and memory, but the literature has shown mixed results.

Much evidence has associated dopamine with the brain’s reward system. For this reason, dopamine has been called the “feel good” or pleasure chemical. Stimulation of the neurotransmitter, dopamine, makes us feel good.
When we solve problems and make decisions and judgments, we very often use mental shortcuts (so-called heuristics). We use these heuristics if we neither have resources nor time to compare all available information before making a choice. In other words, heuristics ease the cognitive load
When we sleep, we undergo different stages of sleep. The deepest stage of sleep is REM (rapid eye movement) sleep. It has been called so because it can be recognized by rapid, random eye movements. This stage of sleep normally occurs in the early hours
The deeper we process information, the better we will remember it. It’s as simple as that. Luckily, there is a way to improve our memory, but it takes effortful and intentional processing. This means, if we want to improve our memory, we must practice.
