The second thing is if you look at play, it shows an age related change. So as animals grow older, the nature of their play changes. The rules begin to shift somewhat, which makes some sense. If you look at little children, infants playing versus five year olds playing versus 12 year olds playing, they don\u2019t all play the same, and that\u2019s true in other animals as well; there are changes in play behaviour. Now, one question we\u2019ve asked is what if you manipulate the amount of play animals are allowed to engage in. So what we can do is we can say we\u2019ll take an animal when they\u2019re weaned and we\u2019ll place them with an adult animal. Adult rodents don\u2019t play with the offspring; they interact with the offspring, they\u2019ll tolerate the play for a few seconds then they don\u2019t want to do it. It\u2019s really one sided because it\u2019s rough and tumble play and you couldn\u2019t have an adult male rat playing with an animal that\u2019s a fraction of his size without hurting the animal probably. So we\u2019ve got the situation where we take away the infants, or the juveniles now, place them with an adult, or several adults, so now we\u2019ve manipulated the number of animals that are there. Or we can have them live with one sibling, or several siblings, so controlled two things here; we\u2019ve manipulated two things: the amount of social interaction which will vary with the number of animals you\u2019re living with, and the amount of play. The more animals there are to play with, the more play you\u2019re going to engage in, which makes sense. <\/p>\n","protected":false},"excerpt":{"rendered":"
