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.\u003c\/p\u003e","brand":"Mia Karts","offers":[{"title":"Default Title","offer_id":51735412605216,"sku":"NEW0306456958","price":189.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/7426\/3840\/files\/61g3TcL2vjL.jpg?v=1779484227","url":"https:\/\/miakarts.com\/products\/new-aspects-of-human-ethology-recent-advances-in-phytochemistry-0306456958","provider":"Miakarts Books","version":"1.0","type":"link"}
