This research opens the door to much-needed neurophysiological studies of spontaneous synchronization in monkeys, which could shed light into human behavioral dysfunctions such as those observed in patients with autism spectrum disorders, echopraxia and echolalia<\/strong> \u2013 where patients uncontrollably imitate others.<\/p>\n In the research, published today in the journal Scientific Reports<\/i>, the team led by Naotaka Fujii developed an experimental set-up to test whether pairs of Japanese macaque monkeys synchronize a simple push-button movement.<\/p>\n Before the experiment, the monkeys were trained to push a button with one hand. In a first experiment the monkeys were paired and placed facing each other and the timing of their push-button movements was recorded. The same experiment was repeated but this time each monkey was shown videos of another monkey pushing a button at varying speeds<\/strong>. And in a last experiment the macaques were not allowed to either see or hear their video-partner.<\/p>\n The results show that the monkeys modified their movements \u2013 increased or decreased the speed of their push-button movement – to be in synchrony with their partner, both when the partner was real and on video. The speed of the button pressing movement changed to be in harmonic or sub-harmonic synchrony with the partners’ speed. However, different pairs of monkeys synchronized differently and reached different speeds, and the monkeys synchronized their movements the most when they could both see and hear their partner.<\/p>\n The researchers note that this behavior cannot have been learnt by the monkeys during the experiment, as previous research has shown that it is extremely difficult for monkeys to learn intentional synchronization<\/strong>.<\/p>\n They add: “The reasons why the monkeys showed behavioral synchronization are not clear. It may be a vital aspect of other socially adaptive behavior, important for survival in the wild<\/strong>.”<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":" From the RIKEN press release via EurekAlert!: Japanese researchers show for the first time that primates modify their body movements to be in tune with others, just like humans do….

<\/a>Japanese researchers show for the first time that primates modify their body movements to be in tune with other<\/strong>s, just like humans do. Humans unconsciously modify their movements to be in synchrony with their peers.
\nFor example, we adapt our pace to walk in step or clap in unison at the end of a concert. This phenomenon is thought to reflect bonding and facilitate human interaction<\/strong>. Researchers from the RIKEN Brain Science Institute report today that pairs of macaque monkeys also spontaneously coordinate their movements to reach synchrony.<\/p>\n
