AbstractSocial play behavior was studied in eleven groups of tame, color-ringed Arabian babblers (Turdoides squamiceps) at the Shezaf nature reserve near Hazeva in the Rift Valley in Israel. 2500 instances of play were recorded in 950 hours of observations carried out from July 1981 to June 1983. Four hours of play interactions were recorded on video-tape and were analyzed using slow-motion techniques. Babblers' play fits all the criteria for 'social play' described by Loizos (1967) and by Muller-Schwarze (1978). The most common forms of play observed were wrestling, displacement (king-of-the-hill), chases, and tug-of-war. Several play-signals were identified: crouching, rolling over, elevation of sticks, play bow, establishing eye contact and freezing briefly in the middle of play. No vocal play-signals were observed. The ontogeny of play is briefly described. Play activity diminishes with age. Dominants play less than subordinates. Babblers tend to play with individuals close to them in rank. Breeding females rarely play. There was no effect of age, dominance or gender on the type of play. When playing, dominants use play-signals more often than subordinates do. Social tension in a group inhibited play activity. Babblers play more in summer than in winter. Bouts of play tend to alternate with bouts of allopreening. Food supplementation increased both activities. Play is more demanding than allopreening, both physically and socially. It is suggested that in babblers testing the social bond is a major component in both social play and allopreening.

AbstractActions called play signals have evolved in many species in which social play has been observed. Despite there being only few empirical demonstrations, it generally is accepted that play signals are important in the initiation ("I want to play") and maintenance ("I still want to play") of ongoing social play. In this study I consider whether a specific and highly stereotyped signal, the bow, is used to maintain social play in adult and infant domestic dogs, infant wolves, and infant coyotes. To answer this question the temporal placement of bows relative to actions that are also used in other contexts (dominance or predatory encounters) such as biting accompanied by rapid side-to-side shaking of the head was analyzed to determine if bows performed during ongoing social play are used to communicate the message "I want to play despite what I am going to do or just did - I still want to play". The non-random occurrence of bows supports the hypothesis that bows are used to maintain social play in these canids when actions borrowed from other contexts, especially biting accompanied by rapid side-to-side shaking of the head, are likely to be misinterpreted.

AbstractThe present study examined the hypothesis that gelotophobia blurs the emotional responses between ridicule and good-natured teasing. Ridicule should induce negative feelings and teasing happiness and surprise in individuals not suffering gelotophobia. Gelotophobes will discriminate less between the two. Their responses to teasing will be similar to ridicule. A sample of adults (N = 105) specified which emotions they would experience in nine scenarios of social interactions pre-selected to represent bullying ridicule or good-natured teasing. Ridicule elicited strong responses of shame, fear and anger, and other negative emotions but low happiness and surprise. Responses of gelotophobes and non-gelotophobes were highly parallel, with the exception that among extreme gelotophobes stronger shame and fear were displayed than among non-gelotophobes. Good-natured teasing seemed to elicit happiness and surprise and low levels of negative emotions among the non-gelotophobes. Among the gelotophobes, however, it was the negative emotions; primarily shame, fear, and anger that were exhibited as the emotional response pattern. In fact, the emotion profile to good-humored teasing was highly similar to the profile in response to the bullying-ridiculing situations. Gelotophobes' perceptions do not discriminate between playful teasing and good-natured teasing. They do not identify the safe and non-threatening quality of the teasing situations. Treatment of gelotophobes should, therefore, involve helping them to identify the play-signals, i.e., the meta-message that the interaction is playful, for fun and that no harm is intended.
