A study published by psychology professor and the University of Erasmus in Rotterdam, Netherlands, investigated the way in which the processes involving knowledge, including thought, experience, and the use of the senses influence the concept of Love. According to Sandra Langeslag, who is the professor conducing the research, when she asked people what they thought about the concept of love; she got varied reactions that fluctuated between the positive feelings of love and its counterpart; hatred.

The science behind love

According to the data collected by Professor Langeslag from varied collected data and brainwave analysis, people answered positively to questions that included whether positive thoughts (kind, smart, considerate, gentle) relating to one´s beloved person could increase the feeling of love.

On the other hand, when they were asked if negative thoughts of personality could increase love, they answered that love tended to decrease.

The way in which love improves cognition

People tend to pay more attention to information related to their beloved ones. In this respect, when a person´s beloved one is a fan of, or interested in a given subject, that person will pay more attention to the things that their beloved one is interested in. On the contrary, people may lose concentration due to the fact that he/she is constantly thinking about the other person, affecting work or personal performance.


According to Professor Langeslag, feelings of love toward another person might be controlled.

Based on the study, being able to control one´s own feelings of love may be beneficial for conserving emotional health and well-being. For example; one might wish to change his/her own feelings of love in building toward a stable marriage by simply directing positive feelings toward the other individual.

Professor Langeslag began to do research on the concept of love when she was an undergraduate student. It was also the reason she chose to study biopsychology, comprising of chemical and neurological processes that interconnect with human behaviour.
