Since then, a modest number of - searchers have developed our knowledge of this kind of activity, using a variety of methods, and addressing some quite fundamental questions about age changes, sex diff- ences, nature and function of behaviour. In this chapter I will review work on this topic, mentioning particularly the interest in comparing results from different informants and different methods of investigation. Briefly, rough-and-tumble play (or R\u0026amp;T for short) refers to a cluster of behaviours whose core is rough but playful wrestling and tumbling on the ground; and whose general characteristic is that the behaviours seem to be agonistic but in a non-serious, playful c- text. The varieties of R\u0026amp;T, and the detailed differences between rough-and-tumble play and real fighting, will be discussed later. 2. A BRIEF HISTORY OF RESEARCH ON R\u0026amp;T In his pioneering work on human play, Groos (1901) described many kinds of rough-and-tumble play. However, R\u0026amp;T was virtually an ignored topic from then until the late 1960's. There was, of course, a flowering of observational research on children in the 1920s and 1930s, especially in North America; but this research had a strong practical o- entation, and lacked the cross-species perspective and evolutionary orientation present in Groos' work.\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9781475785791\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9780306456954\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9781475785791","offer_id":39414907207773,"sku":"9781475785791","price":160.49,"currency_code":"EUR","in_stock":true},{"title":"Hardcover - 9780306456954","offer_id":51779027526,"sku":"9780306456954","price":160.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/440f2216-03f5-4bc9-894a-3a8a9212b5f1.jpg?v=1761800443","url":"https:\/\/shop.autorenwelt.de\/products\/new-aspects-of-human-ethology-von-klaus-atzwanger-karl-grammer-alain-schmitt-katrin-schafer-hrsg","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
