-play is all motor activity performed postnatally that appears to be purposeless, in which motor patterns from other contexts may often be used in modified forms and altered temporal sequencing
-can be problems around this definition
what can repetitive pacing show in a zoo animal
-boredom
-frustration
-lacks purpose
why may play seem ‘apparently purposeless’
-observer may fail to decipher the immediate benefit of play
-the true benefit (function) may not occur until much later
-the benefits may be multiple and confounding
costs of play

-reduced vigilance
-increased predation
-risk of injury
-85% of prey get killed by predators whilst playing
taxonomic occurrence of play

play in meerkats
-lynda Sharpe tested several ideas such as subsequent fighting success, reduce aggression, social cohesion and dispersal partnerships in meerkats but none of these were a reason for play
-only 6% of the waking day spent playing
-when they did play it was chaos
-they tried painting rings on their tails to try and relate behaviour to individuals
-tested meerkats because they’re easy to study and friendly with humans

-cats play with rodent prey
-gulls drop-catching stones or tired migrants (supporting idea that play is practice for hunting )
-kingfishers catching sticks
locomotor play
-2 hypotheses: it provides ‘lay of the land’, and provides exercise and development of motor skills
social play
-hypotheses are that it enhances social skills, that it facilitates long term relationships and enhances cognitive skills
-play fighting in mammals- example in children especially boys
-gorillas flash their teeth in play fighting if the fighting gets too rough to show that they’re still playing
-other social play signals are: head (shaking, ear, eye movement, open mouth), vocalisation, tail (posture, wagging), ambulatory (gambling, stalking, shaking), body posture (bow, roll on back, crouch and stare, outstretched paw)
why is playing fair beneficial
-gains of cheating are low e.g. exclusion from groups
general play theory from Marek Spinka
play creates novel situations and therefore enables animals to deal better with unexpected events later in life
-rates deprived of play respond negatively to the unexpected
