All of our thoughts are attached to emotions. They are like Siamese twins. In fact the link to emotions is so strong that our clearest memories, those with vivid details are the emotionally charged ones. In fact you can remember so far back to your childhood, your favorite toys, warm moments or painful ones like falling off your bicycle because they were emotionally charged events. In that regard, the Swiss psychologist Jean Piaget (1896 to 1980), a pioneer in the study of child development, described a "logic of emotions.". According to Piaget, the emotions are both the engines and mediators of our thought processes, perceptions and activities. They control and assess what we think and what will be stored in our memories and what will not.
