Forscher haben sich mit dem Verhalten von Rhesusaffen beschäftigt – und dabei herausgefunden, dass sie uns Menschen ähneln.

In , his colleague James Robertson produced a short and controversial documentary film, titled A Two-Year-Old Goes to Hospital, demonstrating the almost-immediate effects of maternal separation.

Bowlby de-emphasized the mother's role in feeding as a basis for the development of a strong mother—child relationship, but his conclusions generated much debate.

It was the debate concerning the reasons behind the demonstrated need for maternal care that Harlow addressed in his studies with surrogates.

Physical contact with infants was considered harmful to their development, and this view led to sterile, contact-less nurseries across the country.

Bowlby disagreed, claiming that the mother provides much more than food to the infant, including a unique bond that positively influences the child's development and mental health.

To investigate the debate, Harlow created inanimate surrogate mothers for the rhesus infants from wire and wood. For this experiment, he presented the infants with a clothed mother and a wire mother under two conditions.

Overwhelmingly, the infant macaques preferred spending their time clinging to the cloth mother. Harlow concluded that there was much more to the mother—infant relationship than milk, and that this "contact comfort" was essential to the psychological development and health of infant monkeys and children.

It was this research that gave strong, empirical support to Bowlby's assertions on the importance of love and mother—child interaction. Successive experiments concluded that infants used the surrogate as a base for exploration, and a source of comfort and protection in novel and even frightening situations.

When the infant's surrogate mother was present, it clung to her, but then began venturing off to explore. If frightened, the infant ran back to the surrogate mother and clung to her for a time before venturing out again.

Without the surrogate mother's presence, the monkeys were paralyzed with fear, huddling in a ball and sucking their thumbs. In the "fear test", infants were presented with a fearful stimulus, often a noise-making teddy bear.

When the surrogate mother was present, however, the infant did not show great fearful responses and often contacted the device—exploring and attacking it.

Another study looked at the differentiated effects of being raised with only either a wire-mother or a cloth-mother. Harlow's interpretation of this behavior, which is still widely accepted, was that a lack of contact comfort is psychologically stressful to the monkeys, and the digestive problems are a physiological manifestation of that stress.

The importance of these findings is that they contradicted both the traditional pedagogic advice of limiting or avoiding bodily contact in an attempt to avoid spoiling children, and the insistence of the predominant behaviorist school of psychology that emotions were negligible.

Feeding was thought to be the most important factor in the formation of a mother—child bond. Harlow concluded, however, that nursing strengthened the mother—child bond because of the intimate body contact that it provided.

He described his experiments as a study of love. He also believed that contact comfort could be provided by either mother or father. Though widely accepted now, this idea was revolutionary at the time in provoking thoughts and values concerning the studies of love.

Some of Harlow's final experiments explored social deprivation in the quest to create an animal model for the study of depression.

This study is the most controversial, and involved isolation of infant and juvenile macaques for various periods of time.

Monkeys placed in isolation exhibited social deficits when introduced or re-introduced into a peer group. They appeared unsure of how to interact with their conspecifics , and mostly stayed separate from the group, demonstrating the importance of social interaction and stimuli in forming the ability to interact with conspecifics in developing monkeys, and, comparatively, in children.

Critics of Harlow's research have observed that clinging is a matter of survival in young rhesus monkeys, but not in humans, and have suggested that his conclusions, when applied to humans, overestimate the importance of contact comfort and underestimate the importance of nursing.

Harlow first reported the results of these experiments in "The Nature of Love", the title of his address to the sixty-sixth Annual Convention of the American Psychological Association in Washington, D.

Beginning in , Harlow and his students began publishing their observations on the effects of partial and total social isolation. Partial isolation involved raising monkeys in bare wire cages that allowed them to see, smell, and hear other monkeys, but provided no opportunity for physical contact.

Total social isolation involved rearing monkeys in isolation chambers that precluded any and all contact with other monkeys. Harlow et al.

These monkeys were then observed in various settings. For the study, some of the monkeys were kept in solitary isolation for 15 years.

In the total isolation experiments, baby monkeys would be left alone for three, six, 12, or 24 [20] [21] months of "total social deprivation".

The experiments produced monkeys that were severely psychologically disturbed. Harlow wrote:. No monkey has died during isolation.

When initially removed from total social isolation, however, they usually go into a state of emotional shock, characterized by One of six monkeys isolated for 3 months refused to eat after release and died 5 days later.

The autopsy report attributed death to emotional anorexia. The effects of 6 months of total social isolation were so devastating and debilitating that we had assumed initially that 12 months of isolation would not produce any additional decrement.

This assumption proved to be false; 12 months of isolation almost obliterated the animals socially Harlow tried to reintegrate the monkeys who had been isolated for six months by placing them with monkeys who had been raised normally.

Harlow wrote that total social isolation for the first six months of life produced "severe deficits in virtually every aspect of social behavior".

Since Harlow's pioneering work on touch research in development, recent work in rats has found evidence that touch during infancy resulted in a decrease in corticosteroid , a steroid hormone involved in stress, and an increase in glucocorticoid receptors in many regions of the brain.

Investigators have measured a direct, positive relationship between the amount of contact and grooming an infant monkey receives during its first six months of life, and its ability to produce antibody titer IgG and IgM in response to an antibody challenge tetanus at a little over one year of age.

Touch deprivation may cause stress-induced activation of the pituitary—adrenal system , which, in turn, leads to increased plasma cortisol and adrenocorticotropic hormone.

Likewise, researchers suggest, regular and "natural" stimulation of the skin may moderate these pituitary—adrenal responses in a positive and healthful way.

Harlow was well known for refusing to use conventional terminology, instead choosing deliberately outrageous terms for the experimental apparatus he devised.

This came from an early conflict with the conventional psychological establishment in which Harlow used the term "love" in place of the popular and archaically correct term, "attachment".

Such terms and respective devices included a forced-mating device he called the "rape rack", tormenting surrogate-mother devices he called " Iron maidens ", and an isolation chamber he called the " pit of despair ", developed by him and a graduate student, Stephen Suomi.

In the last of these devices, alternatively called the "well of despair", baby monkeys were left alone in darkness for up to one year from birth, or repetitively separated from their peers and isolated in the chamber.

These procedures quickly produced monkeys that were severely psychologically disturbed, and used as models of human depression. Harlow tried to rehabilitate monkeys that had been subjected to varying degrees of isolation using various forms of therapy.

Today, we are psychiatrists trying to achieve normality and equanimity. Many of Harlow's experiments are now considered unethical —in their nature as well as Harlow's descriptions of them—and they both contributed to heightened awareness of the treatment of laboratory animals, and helped propel the creation of today's ethics regulations.

The monkeys in the experiment were deprived of maternal affection, potentially leading to what we now refer to as "panic disorders".

William Mason, another one of Harlow's students who continued conducting deprivation experiments after leaving Wisconsin, [34] has said that Harlow "kept this going to the point where it was clear to many people that the work was really violating ordinary sensibilities, that anybody with respect for life or people would find this offensive.

It's as if he sat down and said, 'I'm only going to be around another ten years. What I'd like to do, then, is leave a great big mess behind.

Stephen Suomi , a former Harlow student who now conducts maternal deprivation experiments on monkeys at the National Institutes of Health , has been criticized by PETA and members of the U.

Yet another of Harlow's students, Leonard Rosenblum, also went on to conduct maternal deprivation experiments with bonnet and pigtail macaque monkeys, and other research, involving exposing monkeys to drug—maternal-deprivation combinations in an attempt to "model" human panic disorder.

Rosenblum's research, and his justifications for it, have also been criticized. A theatrical play, The Harry Harlow Project , based on the life and work of Harlow, has been produced in Victoria and performed nationally in Australia.

Die Anzahl der Gene zunächst auf Rhesusaffen leben in Asien, ihr Verbreitungsgebiet erstreckt sich von Afghanistan über Indien — ihrem Hauptverbreitungsgebiet — bis ins südliche China und Thailand.

Verwilderte Gruppen leben auch in Florida und auf Puerto Rico. Rhesusaffen sind wie alle Altweltaffen tagaktiv.

Je nach Lebensraum können sie sich vorrangig am Boden oder in den Bäumen aufhalten. Sie bewegen sich meist quadruped auf allen vieren fort und können auch gut schwimmen und dabei Distanzen bis zu einem Kilometer zurücklegen.

In ihrem Gruppenverhalten entsprechen Rhesusaffen den übrigen Makaken. Weibchen verbleiben zeitlebens in ihrer Geburtsgruppe, Cliquen nahe verwandter Weibchen bilden so den matrilinearen Kern der Gruppe.

Männchen müssen beim Eintreten der Geschlechtsreife ihre Geburtsgruppe verlassen und verbringen ihr Leben oft in mehreren Gruppen hintereinander.

Die Weibchen etablieren eine stabile, dauerhafte Rangordnung, die vorwiegend vom Rang der Mutter abhängt und unter anderem in besserem Zugang zu Nahrungsquellen sichtbar wird.

Die Rangordnung der Männchen ist weniger stabil, der Status der Männchen basiert auf einer Kombination aus sozialem und aggressivem Verhalten.

Wenn ein Männchen die dominante Rolle in der Gruppe innehat, behält es diese für durchschnittlich zwei Jahre bei, ehe es von einem anderen verdrängt wird.

Das Territorialverhalten ist wenig ausgeprägt: Die Streifgebiete der einzelnen Gruppen überlappen und verschiedene Gruppen treffen sich häufig, was meistens friedlich abläuft.

Rhesusaffen kommunizieren mit einer Reihe von Lauten und Gesten. Häufig sind Gurr- und Grunzlaute zu hören, etwa bei der Fortbewegung oder wenn sich ein Tier einem anderen zum Grooming annähert.

Es gibt auch Zwitscherlaute, die eine Nahrungsquelle anzeigen, schrille Alarmschreie und Drohlaute. Während Tiere, die in höheren Regionen leben, eine fixe Paarungszeit haben im Herbst, sodass die Jungen im Frühling zur Welt kommen , gibt es bei Flachlandbewohnern keine eindeutigen Zeiten.

Die Tragzeit beträgt rund Tage, meist kommt ein einzelnes Jungtier zur Welt. Nicht nur die Mutter, sondern auch andere Weibchen der Gruppe und gelegentlich auch Männchen kümmern sich um das Junge, das im zweiten Lebenshalbjahr entwöhnt wird.

Rhesusaffen können bis zu 30 Jahre alt werden. Rhesusaffen werden in ihrem westlichen Verbreitungsgebiet Pakistan, Indien vor allem von Leoparden gerissen.

Aber auch Bengaltiger und Wölfe stellen eine Gefahr für die Primaten dar. Junge Tiere werden auch von Bengalkatzen oder Rohrkatzen gerissen.

Im Hinduismus gelten Rhesusaffen als heilige Tiere.
