Unconditional love is known as affection without any limitations, or love without conditions. This term is sometimes associated with other terms such as true altruism or complete love. Each area of expertise has a certain way of describing unconditional love, but most will agree that it is that type of love which has no bounds and is unchanging. It is a concept comparable to true love, a term which is generally used to describe love between lovers. Unconditional love is also used to describe love between family members, comrades in arms and between others in highly committed relationships. An example of this is a parent's love for their child; no matter a test score, a life changing decision, an argument, or a strong belief, the amount of love that remains between this bond is seen as unchanging and unconditional.
In Christianity, unconditional love is thought to be part of the Four Loves; affection, friendship, eros, and charity. In ethology, or the study of animal behavior, unconditional love would refer to altruism which in turn refers to the behavior by individuals that increases the fitness of another while decreasing the fitness of the individual committing the act. In psychology, unconditional love refers to a state of mind in which one has the goal of increasing the welfare of another, despite any evidence of benefit for oneself. The term is also widely used in family and couples counseling manuals. Dogs are often considered to be examples of animals displaying unconditional love.
Conditional love
Some authors make a distinction between unconditional love and conditional love. In conditional love: love is 'earned' on the basis of conscious or unconscious conditions being met by the lover, whereas in unconditional love, love is "given freely" to the loved one "no matter what". Loving is primary. Conditional love requires some kind of finite exchange, whereas unconditional love is seen as infinite and measureless. Unconditional love should not be mistaken with unconditional dedication: unconditional dedication or "duty" refers to an act of the will irrespective of feelings (e.g. a person may consider they have a duty to stay with someone); unconditional love is an act of the feelings irrespective of will.
Unconditional love separates the individual from her or his behaviors. However, the individual may exhibit behaviors that are unacceptable in a particular situation. To begin with a simple example: one acquires a puppy. The puppy is cute, playful, and the owner's heart swells with love for this new family member. Then the puppy urinates on the floor. The owner does not stop loving the puppy, but needs to modify the behavior through training and education.
Neurological
There has been some evidence to support a neural basis for unconditional love, showing that it stands apart from other types of love.
In a study conducted by Mario Beauregard and his colleagues, using an fMRI procedure, they studied the brain imaging of participants who were shown different sets of images either referring to "maternal love" (unconditional love) or "romantic love". Seven areas of the brain became active when these participants called to mind feelings of unconditional love. Three of these were similar to areas that became active when it came to romantic love. The other four active parts were different, showing certain brain regions associated with rewarding aspects, pleasurable (non sexual) feelings, and human maternal behaviors are activated during the unconditional love portions of the experiment. Through the associations made between the different regions, results show that the feeling of love for someone without the need of being rewarded is different from the feeling of romantic love.
Along with the idea of "mother love", which is associated with unconditional love, a study found patterns in the neuroendocrine system and motivation-affective neural system. Using the fMRI procedure, mothers watched a video of them playing with their children in a familiar environment, like home. The procedure found part of the amygdala and nucleus accumbenswere responsive on levels of emotion and empathy. Emotion and empathy (compassion) are descriptives of love, therefore it supports the idea that the neural occurrences are evidence of unconditional love.
