We Help Friends Due To Empathy; Relatives Due To Expectation Of Reciprocity

ScienceDaily (Mar. 24, 2008) — Empathy is an emotional reaction to the plight of others. Empathy can lead to altruistic behaviour, i.e. helping someone with the sole intention of enhancing that person’s wellbeing. If we see people in difficulty, for example, we feel the same emotions, and this may prompt us to help them. Yet the relationship between empathy and altruism is still far from clear. Psychologist Lidewij Niezink has researched this subject. She concluded that when we help friends in need, we are prompted by feelings of empathy, and that when we help relatives we do so because we have expectations of reciprocity.

Niezink will receive her PhD on 27 March 2008 at the University of Groningen. She measured the empathic responses by telling the participants in the study about a young woman who is in a wheelchair following a serious accident. The participants then had to answer a series of questions designed to show how much they sympathise and identify with the woman.
Social comparison
Among other things, Niezink studied the empathetic reactions of people who often compare themselves with others. ‘We all compare ourselves with the people around us, but some people do this more than others. When the people in this group compare themselves with someone in a worse position, they often experience negative emotions such as tension, agitation, anxiety and irritation.’ Niezink discovered that these negative emotions are actually an expression of empathy. These people feel involved with the person in need, and identify with him/her. The negative emotions are a way of expressing this.
Family and friends
Niezink also studied the role of empathetic feelings in relationships with friends and family members. She discovered that we help friends for different reasons than family members. ‘People help friends out of feelings of empathy, but they help family members because they have expectations about reciprocation.’ This result is surprising, because it was always assumed that empathy was primarily a characteristic of family relationships. ‘But it is logical when you think about it. When you move house, it’s always your brother who comes to help. You can usually rely on family. We do not choose our families, but we do choose our friends. We feel a greater sense of connection with friends, so feelings of empathy are more important.
Altruistic options model
Niezink also compared various studies of empathy, and concludes that the methods varied quite considerably. ‘They are not talking about the same concept. That makes it more difficult to study altruism.’ Niezink then developed the ‘altruistic choice model’. The model works as follows. You see the suffering of others and this leads to a feeling of empathy, over which you have no control. This can be followed by various emotional responses: sympathizing/identifying with the person in question, concern or ‘softheartedness’ (tender feelings). These are responses that we can influence. These responses, in turn, can lead to compassion and altruism, i.e. understanding the other person’s suffering and the willingness to alleviate it. According to Niezink: ‘Altruism is a choice and something that we can actively cultivate when we observe others in need.’
Negative perception unjustified
Niezink is surprised about the fact that altruism is undervalued in our society. ‘We are pack animals. We cannot exist in isolation, so it is no scandal if we are willing to help each other. I’m not saying we must, but we can. Altruism makes the world a more pleasant place.’ It is rewarding to help someone. ‘Some people say, therefore, that helping others is based on selfish motives. If you help someone and it has positive consequences for you, that does not mean to say that your underlying motives are not altruistic.'

Feeling Close To A Friend Increases Progesterone, Boosts Well-being And Reduces Anxiety And Stress

http://www.sciencedaily.com/releases/2009/06/090602171941.htm
ScienceDaily (June 3, 2009) — Why does dishing with a girlfriend do wonders for a woman's mood?

A University of Michigan study has identified a likely reason: feeling emotionally close to a friend increases levels of the hormone progesterone, helping to boost well-being and reduce anxiety and stress.
"This study establishes progesterone as a likely part of the neuroendocrine basis of social bonding in humans," said U-M researcher Stephanie Brown, lead author of an article reporting the study findings, published in the current (June 2009) issue of the peer-reviewed journal Hormones and Behavior.
A sex hormone that fluctuates with the menstrual cycle, progesterone is also present in low levels in post-menopausal women and in men. Earlier research has shown that higher levels of progesterone increase the desire to bond with others, but the current study is the first to show that bonding with others increases levels of progesterone. The study also links these increases to a greater willingness to help other people, even at our own expense.
"It's important to find the links between biological mechanisms and human social behavior," said Brown, is a faculty associate at the U-M Institute for Social Research (ISR) and an assistant professor of internal medicine at the U-M Medical School. She is also affiliated with the Ann Arbor Veterans Affairs Hospital. "These links may help us understand why people in close relationships are happier, healthier, and live longer than those who are socially isolated."
Progesterone is much easier to measure than oxytocin, a hormone linked to trust, pair-bonding and maternal responsiveness in humans and other mammals. Oxytocin can only be measured through an invasive spinal tap or through expensive and complex brain imaging methods, such as positron emission tomography scans. Progesterone can be measured through simple saliva samples and may be related to oxytocin.
In the current study, Brown and colleagues examined the link between interpersonal closeness and salivary progesterone in 160 female college students.
At the start of the study, the researchers measured the levels of progesterone and of the stress hormone cortisol in the women's saliva, and obtained information about their menstrual cycles and whether they were using hormonal contraceptives or other hormonally active medications.
To control for daily variations in hormone levels, all the sessions were held between noon and 7 p.m.
The women were randomly assigned to partners and asked to perform either a task designed to elicit feelings of emotional closeness or a task that was emotionally neutral.
In the emotionally neutral task, the women proofread a botany manuscript together.
After completing the 20-minute tasks, the women played a computerized cooperative card game with their partners, and then had their progesterone and cortisol sampled again.
The progesterone levels of women who had engaged in the emotionally neutral tasks tended to decline, while the progesterone levels of women who engaged in the task designed to elicit closeness either remained the same or increased. The participants' cortisol levels did not change in a similar way.
Participants returned a week later, and played the computerized card game with their original partners again. Then researchers measured their progesterone and cortisol. Researchers also examined links between progesterone levels and how likely participants said they would be to risk their life for their partner.
"During the first phase of the study, we found no evidence of a relationship between progesterone and willingness to sacrifice," Brown said. "But a week later, increased progesterone predicted an increased willingness to say you would risk your life to help your partner."
According to Brown, the findings are consistent with a new evolutionary theory of altruism which argues that the hormonal basis of social bonds enables people to suppress self-interest when necessary in order to promote the well-being of another person, as when taking care of children or helping ailing family members or friends.
The results also help explain why social contact has well-documented health benefits---a relationship first identified nearly 20 years ago by U-M sociologist James House.
"Many of the hormones involved in bonding and helping behavior lead to reductions in stress and anxiety in both humans and other animals. Now we see that higher levels of progesterone may be part of the underlying physiological basis for these effects," Brown said.
