Sadness response strengthens with age
In study, older people reacted more strongly to sad scenes than twentysomethings did

As people grow older, sad films seem sadder.

In a recent study, people in their sixties felt sadder than people in their twenties did after viewing an emotionally distressing scene from a movie. This heightened emotional response to sorrow may reflect a greater compassion for other people and may strengthen social bonds, researchers propose.

The finding is an important contribution to emotion studies because it adds to a growing body of work showing that emotions don’t deteriorate, says Stanford University psychologist Laura Carstensen, who was not involved in the research. “One of the important findings of this is that the emotion system is in no way broken in old age,” she says.

To explore how feelings of sadness change with age, researchers led by Robert Levenson of the University of California, Berkeley brought 222 study participants into the laboratory to watch neutral, disgusting or sad movie clips. The volunteers made up three age groups: young people in their twenties, middle-aged people in their forties, and older people in their sixties. Before watching the movies, participants were hooked up to monitors that recorded physiological responses such as blood pressure, heart rate and breathing patterns.  

Levenson and his team chose two gut-wrenchingly sad scenes to elicit responses: In the first clip, from the movie 21 Grams, a mother is told of the deaths of her two young daughters. The second scene, from The Champ, depicts a young boy watching his father die after a boxing match. (The disgusting clips were also well chosen: They showed a woman eating horse rectum and a man sucking fluid from a cow’s intestines, both on NBC’s Fear Factor. The neutral scene showed two men talking about nothing in the absurdist film Stranger than Paradise.)

In addition to measuring physiological responses to the movie clips, the researchers asked people to describe how they felt. People in their sixties reported stronger feelings of sadness when they watched the sad scenes than did middle-aged or young people, the team found. Older people and middle-aged people also had stronger physiological responses to sad movies than did people in their twenties. People responded similarly to the disgusting scenes, regardless of age.

The findings, which appeared online July 22 in Social Cognition and Affective Neuroscience, suggest that sadness changes with age in a way that’s different than other emotions. “Sadness travels its own special route. In particular, sadness, we think, has a tendency to get a little sharper,” Levenson says.

Earlier studies, including some by Carstensen, have reported that in day-to-day life older people report experiencing more positive emotions than younger people. One explanation for this, says Carstensen, is that older people are more selective, so they may simply avoid sad situations more effectively than young people. And it’s plausible that overall, a person can be very happy and at the same time have a strong sadness response, Levenson says.

One reason for this keener sense of sadness might be that older people have experienced more losses and might be sensitized to sorrow, but Levenson doesn’t think so. When the researchers controlled for whether people had experienced major losses in their lives, the increased response remained.

Instead, Levenson thinks the heightened sadness response might be beneficial for maintaining and strengthening social ties. Sadness “is a very functional emotion,” Levenson says. “It’s an emotion that really brings people towards us and motivates them to help us.”

  • How about effects from generation differences? The oldest age group in this study were born in 1930-40's, where many of them did not have access to TV and movies throughout their childhood, which is the prime time to develop their core personalities. If they did, shows tended to be gentler. Twentysomethings were born into the era of excess (fake or not) violence, sensationalized TV news/shows, overflow of information.

  • I think that older people simply learn over time to put themselves in the place of others. They become less concerned with protecting their own feelings in the process. The empathy channels become more open. Sounds sappy and sentimental, but anger can flow through that channel as well as sympathy.

  • man’s embryonic development:


    We created man from an extract of clay. Then We made him as a drop in a place of settlement, firmly fixed. Then We made the drop into an alaqah (leech, suspended thing, and blood clot), then We made the alaqah into a mudghah (chewed substance)…” (Quran 23:12-14)

    Literally, the Arabic word alaqah has three meanings: (1) leech, (2) suspended thing, and (3) blood clot:

    In comparing a leech to an embryo in the alaqah stage, we find similarity between the two[1] as we can see in figure 1. Also, the embryo at this stage obtains nourishment from the blood of the mother, similar to the leech, which feeds on the blood of others.[2]



    Figure 1: Drawings illustrating the similarities in appearance between a leech and a human embryo at the alaqah stage. (Leech drawing from Human Development as Described in the Quran and Sunnah, Moore and others, p. 37, modified from Integrated Principles of Zoology, Hickman and others. Embryo drawing from The Developing Human, Moore and Persaud, 5th ed., p. 73.)

    The second meaning of the word alaqah is “suspended thing.” This is what we can see in figures 2 and 3, the suspension of the embryo, during the alaqah stage, in the womb of the mother.



    Figure 2: We can see in this diagram the suspension of an embryo during the alaqah stage in the womb (uterus) of the mother. (The Developing Human, Moore and Persaud, 5th ed., p. 66.)



    Figure 3: In this photomicrograph, we can see the suspension of an embryo (marked B) during the alaqah stage (about 15 days old) in the womb of the mother. The actual size of the embryo is about 0.6 mm. (The Developing Human, Moore, 3rd ed., p. 66, from Histology, Leeson and Leeson.)

    The third meaning of the word alaqah is “blood clot.” We find that the external appearance of the embryo and its sacs during the alaqah stage is similar to that of a blood clot. This is due to the presence of relatively large amounts of blood present in the embryo during this stage[3] (see figure 4). Also during this stage, the blood in the embryo does not circulate until the end of the third week.[4] Thus, the embryo at this stage is like a clot of blood


    .
    Figure 4: Diagram of the primitive cardiovascular system in an embryo during the alaqah stage. The external appearance of the embryo and its sacs is similar to that of a blood clot, due to the presence of relatively large amounts of blood present in the embryo. (The Developing Human, Moore, 5th ed., p. 65.)

    So the three meanings of the word alaqah correspond accurately to the descriptions of the embryo at the alaqah stage.
    The next stage mentioned in the verse is the mudghah stage. The Arabic word mudghah means “chewed substance.” If one were to take a piece of gum and chew it in his or her mouth and then compare it with an embryo at the mudghah stage, we would conclude that the embryo at the mudghah stage acquires the appearance of a chewed substance. This is because of the somites at the back of the embryo that “somewhat resemble teethmarks in a chewed substance.”[5] (see figures 5 and 6).




    Figure 5: Photograph of an embryo at the mudghah stage (28 days old). The embryo at this stage acquires the appearance of a chewed substance, because the somites at the back of the embryo somewhat resemble teeth marks in a chewed substance. The actual size of the embryo is 4 mm. (The Developing Human, Moore and Persaud, 5th ed., p. 82, from Professor Hideo Nishimura, Kyoto University, Kyoto, Japan.)




    Figure 6: When comparing the appearance of an embryo at the mudghah stage with a piece of gum that has been chewed, we find similarity between the two.

    A) Drawing of an embryo at the mudghah stage. We can see here the somites at the back of the embryo that look like teeth marks. (The Developing Human, Moore and Persaud, 5th ed., p. 79.)

    B) Photograph of a piece of gum that has been chewed.

    How could Muhammad, may the mercy and blessings of God be upon him, have possibly known all this 1400 years ago, when scientists have only recently discovered this using advanced equipment and powerful microscopes which did not exist at that time? Hamm and Leeuwenhoek were the first scientists to observe human sperm cells (spermatozoa) using an improved microscope in 1677 (more than 1000 years after Muhammad). They mistakenly thought that the sperm cell contained a miniature preformed human being that grew when it was deposited in the female genital tract.[6]

    Professor Emeritus Keith L. Moore[7] is one of the world’s most prominent scientists in the fields of anatomy and embryology and is the author of the book entitled The Developing Human, which has been translated into eight languages. This book is a scientific reference work and was chosen by a special committee in the United States as the best book authored by one person. Dr. Keith Moore is Professor Emeritus of Anatomy and Cell Biology at the University of Toronto, Toronto, Canada. There, he was Associate Dean of Basic Sciences at the Faculty of Medicine and for 8 years was the Chairman of the Department of Anatomy. In 1984, he received the most distinguished award presented in the field of anatomy in Canada, the J.C.B. Grant Award from the Canadian Association of Anatomists. He has directed many international associations, such as the Canadian and American Association of Anatomists and the Council of the Union of Biological Sciences.

    In 1981, during the Seventh Medical Conference in Dammam, Saudi Arabia, Professor Moore said: “It has been a great pleasure for me to help clarify statements in the Quran about human development. It is clear to me that these statements must have come to Muhammad from God, because almost all of this knowledge was not discovered until many centuries later. This proves to me that Muhammad must have been a messenger of God.”[8] (To view the RealPlayer video of this comment click here).

    Consequently, Professor Moore was asked the following question: “Does this mean that you believe that the Quran is the word of God?” He replied: “I find no difficulty in accepting this.”[9]

    During one conference, Professor Moore stated: “....Because the staging of human embryos is complex, owing to the continuous process of change during development, it is proposed that a new system of classification could be developed using the terms mentioned in the Quran and Sunnah (what Muhammad, may the mercy and blessings of God be upon him, said, did, or approved of). The proposed system is simple, comprehensive, and conforms with present embryological knowledge. The intensive studies of the Quran and hadeeth (reliably transmitted reports by the Prophet Muhammad’s companions of what he said, did, or approved of) in the last four years have revealed a system for classifying human embryos that is amazing since it was recorded in the seventh century A.D. Although Aristotle, the founder of the science of embryology, realized that chick embryos developed in stages from his studies of hen’s eggs in the fourth century B.C., he did not give any details about these stages. As far as it is known from the history of embryology, little was known about the staging and classification of human embryos until the twentieth century. For this reason, the descriptions of the human embryo in the Quran cannot be based on scientific knowledge in the seventh century. The only reasonable conclusion is: these descriptions were revealed to Muhammad from God. He could not have known such details because he was an illiterate man with absolutely no scientific training.”[10]

  • This is very interesting. I would love to see a study of older people who have had Botox treatments since 2006, when they were approved by the FDA versus older people who have never had any Botox treatments. Given this article recently in Science News, "Botox injections put a crease in emotional evaluations "

    I would think that older people who have been exposed to botox injections for a prolonged time would feel a great deal less. i would suspect that older people have stronger feelings because the neural pathways to those feelings have been constantly re-enforced through use over time. They just simply have had more time to respond to feelings.

  • Can we please stick to science and not outdated religious conjecture. The man created from clay and a puff of breath, or a woman's rib along with other religious myths belong in the fairy tale section not the science section please.
