Where is our conscience

The relationship between mother and child might have been the evolutionary foundation of conscience. What is our conscience, and where does it come from?

That we have a conscience at all relates to how evolution has shaped our neurobiology for social living. Thus, we judge what is right or wrong using feelings that urge us in a general direction and judgement that shapes these urges into actions. This idea of conscience as a neurobiological capacity for internalizing social norms contrasts with strictly philosophical accounts of how and why we tell right from wrong.

Moreover, many of our moral rules — such as the idea that we should not betray our friends or abandon our children — have clearly been shaped by natural selection to optimize our capacity to live in groups. Other rules, for instance regarding the correctness of reciprocity, are similar: we feel quite intensely and innately that if someone gives us a gift of food, we should reciprocate on a future occasion.

Churchland briefly touches on how other primates, such as chimpanzees, have been observed acting in ways that echo conscience. These include behaviours analysed by primatologist Frans de Waal: cooperating towards common goals, sharing food, adopting orphans and grieving. Churchland argues that such examples point to the evolutionary origins of human conscience. To build that case, she first focuses on the fundamental bond between mothers and children. This relationship, she argues, was eventually extended across evolutionary time to mates, more distant kin, and friends.

Conscience is essential to our ability to sustain and benefit from such attachments. Every interaction we have with others helps form our conscience.

Our consciences are also formed by watching other people and understanding the choices they make. Imagine you and a friend are playing outside. Your friend falls down and hurts their knee. What would you do? Most people would either help their friend up or go find a trusted adult to help.

They have learned this is the right thing to do from prior experience or from watching others. How would you feel afterward? Most people would feel guilt for not helping. They might even feel shame for causing a friend even more distress. These emotions can manifest themselves in physical symptoms, like a stomachache.

Can you think of a time when you had to make a tough choice between right and wrong? What did your conscience tell you? Did you listen? Talk with an adult about how your conscience guides your daily life.

We are undergoing some spring clearing site maintenance and need to temporarily disable the commenting feature. Thanks for your patience. Drag a word to its definition. In each case, the train tipped over, spilling the water before it reached its destination.

This accident seemed to be caused by whomever had started the train. In some trials, the child was allowed to get paper towels to clean up the mess. In others, an adult grabbed the towels first.

But when an adult cleaned up the mess that a child had thought he had caused, the child still had dilated pupils afterward. This suggests these kids may have felt guilty about making the mess, the researchers say.

If an adult cleaned it up, the child had no chance to right that wrong. This left them feeling bad. We remain frustrated if someone else repairs the harm we accidentally caused. Guilt is an important emotion, she notes. And it starts playing a role early in life. As kids get older, their sense of guilt may become more complex, she says. Or they might feel guilty when they just think about doing something bad.

What happens inside someone when she feels pangs of conscience? Scientists have done dozens of studies to figure this out. Many of them focus on morality, the code of conduct that we learn — the one which helps us judge right from wrong.

Scientists have focused on finding the brain areas involved with moral thinking. To do this, they scanned the brains of people while those people were looking at scenes showing different situations. For instance, one might show someone hurting another.

Or a viewer might have to decide whether to save five fictional people by letting someone else die. But there turned out not to be one. In fact, there are several areas throughout the brain that turn on during these experiments. By working together, these brain areas probably become our conscience. This network is actually made up of three smaller networks, says Fiery Cushman of Harvard University in Cambridge, Mass.

This psychologist specializes in morality. One brain network helps us understand other people. Another allows us to care about them. The last helps us make decisions based on our understanding and caring, Cushman explains. The first of these three networks is made up of a group of brain areas that together are called the default mode network. It helps us get inside the heads of other people, so we can better understand who they are and what motivates them.

This network involves parts of the brain that become active when we daydream. It is part of the Ventrolateral Frontal Cortex, a region of the brain known for over years for being involved in many of the highest aspects of cognition and language.

To look into which part of this region actually controls our superior decision making , scientists carried out MRI scans in both humans and monkeys. They found one area of the cortex that had no equivalent in the macaque monkeys — an area called the lateral frontal pole prefrontal cortex. It does not seem to have an equivalent in the monkey.
