Mother chimps crucial for offspring’s social skills

13.09.2013
Orphaned chimpanzees are less socially competent than chimpanzees who were reared by their mother.

Researchers from the Max Planck Institute for Psycholinguistics in Nijmegen, The Netherlands, observed that orphaned chimpanzees frequently engaged in social play, but their play bouts were much shorter and resulted in aggression more often. Apparently, chimpanzee mothers endow their offspring with important social skills.

It may not come as a surprise, but mother chimpanzees seem to be important for the development of social skills in young chimpanzees. "Orphaned chimpanzees had more difficulties to successfully coordinate their social play interactions," says Edwin van Leeuwen from the Comparative Cognitive Anthropology Research Group at the Max Planck Institute for Psycholinguistics. "Since social play comprises a complex context in which signals about intentions need to be communicated, it seems that orphaned chimpanzees have missed out on valuable lessons from their mothers."

Van Leeuwen and his co-authors Innocent Mulenga and Diana Lisensky compared the play behaviour of 8 orphaned and 9 mother-reared juvenile chimpanzees at the Chimfunshi Wildlife Orphanage Trust in Zambia. In this institution the orphan chimpanzees are initially cared for by humans. As soon as they are strong enough – usually with one or two years of age – they grow up in an orphan chimp group. “The chimps in the study were between four and nine years old, so they have kind of been raising each other”, explains van Leeuwen. The orphaned and mother-reared chimpanzees matched in age and sex.

Based on previous research, the scientists expected the orphaned juveniles to play less frequently and smoothly than the mother-reared chimpanzees: After all, the orphans had missed their most important caretaker throughout a sensitive socialisation period, and continued to lack a safe and facilitating social environment provided by their mothers.

Contrary to their expectations, the orphaned chimpanzees engaged in social play more frequently than the mother-reared juveniles, although for shorter amounts of time. But social play of the orphaned juveniles resulted more often in aggression than social play of the young chimps that were reared by their mother. "Although the orphaned chimps were motivated to play," Van Leeuwen says, "it seems that they were less able to coordinate their play bouts and prevent them from resulting in aggression."

Just like in humans, chimpanzee mothers seem to be important for the development of adequate social skills in their offspring, the researchers conclude. Van Leeuwen: “Mothers seem to prepare their offspring for challenges that are very important for successful group-living. For orphans, however, the presence of other adult role models may alternatively be beneficial for boosting social competence, which is an important consideration to entertain for sanctuaries dealing with integrations of chimpanzees.”

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Im Focus: A space-time sensor for light-matter interactions

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.

The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...

Im Focus: A transistor of graphene nanoribbons

Transistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years' time. An international research team working with Empa has now succeeded in producing nanotransistors from graphene ribbons that are only a few atoms wide, as reported in the current issue of the trade journal "Nature Communications."

Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the...
