Play behavior in crocodilians

Play behavior in crocodilians is not uncommon, but it remains virtually undescribed in scientific literature. I present the first overview of play behavior of three types (locomotor play, object play and social play) in crocodilians based on original observations, published...

Animal welfare: Could adult play be a false friend?

There is no consensus regarding the functions of play. As play behavior is a characteristic of young stages of development, it has been suggested that the higher prevalence of adult play observed in domestic animals could be the result of...

Play fighting versus real fighting in piglets (Sus scrofa): Similar patterns, different structure

When animals engage in ‘non-serious' fighting (play-fighting) they ‘borrow' motor patterns especially from the aggressive context. It may be difficult to distinguish play- and real-fighting. This is particularly true for piglets (Sus scrofa), which can use play-fighting as a substitute...

Atypical play experiences in the juvenile period has an impact on the development of the medial prefrontal cortex in both male and female rats

In rats reared without play, or with limited access to play during the juvenile period, the dendrites of pyramidal neurons of the medial prefrontal cortex (mPFC) exhibit more branching than rats reared with more typical levels of play. This suggests...

Do bumble bees play?

A variety of animals have been found to interact with and manipulate inanimate objects ‘just for fun', that is, to play. Most clear examples of object play come from mammals and birds. However, whether insects interact with inanimate objects as...

Play behaviour positively relates to weight gain, feeding behaviour and drinking behaviour in weaner pigs (Sus scrofa)

Engagement in play behaviour has been associated with the presence of positive affective states and, thus, proposed to be an indicator of positive animal welfare. However, the interpretation of play in animals remains challenging due to the complexity of motivating...

Animal agency, animal awareness and animal welfare

In nature, animals need to actively engage with the environment in order to prosper in survival and reproduction. Hence, agency is a central adaptive characteristic of animal life. In this paper, I propose that from the adaptive/functional point of view,...

Environmental challenge and animal agency

Challenges are there to be overcome – seen usually as problems to avoid rather than as opportunities to enjoy. However, for humans a life without challenge would be likely to be dull and boring, lacking the enthusiasm and satisfaction that...

The rough-and-tumble play of rats as a natural behavior suitable for studying the social brain

Laboratory rats have been an important model species with which to study the neurobiology of rough-and-tumble play (RTP). RTP in rats involves competition to gain access to the partner's nape of the neck, which is nuzzled with the snout if...

Social play experience in juvenile rats is indispensable for appropriate socio-sexual behavior in adulthood in males but not females

Social play is a dynamic and rewarding behavior abundantly expressed by most mammals during the juvenile period. While its exact function is debated, various rodent studies on the effects of juvenile social isolation suggest that participating in play is essential...
