Rewarding properties of social interactions in adolescent and adult male and female rats: Impact of social versus isolate housing of subjects and partners
Abstract
Social interactions have been shown to be rewarding for adolescent and adult rats; however, there has been little emphasis on comparing the strength of the rewarding value of social stimuli across ontogeny. Since age differences in social interactions may vary with sex or housing circumstances, the present study assessed social conditioned place preference (CPP) in adolescent and adult male and female Sprague‐Dawley rats housed either socially or in isolation and conditioned with either group‐housed or isolate‐housed partners. Isolated animals of both sexes and ages demonstrated social CPP, with the strongest preference emerging in adolescent males. Social CPP was not evident in group‐housed adults whereas group‐housed adolescents developed a preference for the compartment previously paired with similarly housed partners; however, when socially housed adolescents were conditioned with isolated partners, social CPP did not emerge. Age differences in social CPP may reflect age‐related neural alterations in brain systems implicated in regulation of social behavior. © 2004 Wiley Periodicals, Inc. Dev Psychobiol 45: 153‐162, 2004.

If two individuals have similar motivation to play they are both more likely to perform high levels of play, while individuals with divergent motivation to play could result in the less motivated animal not necessarily participating in play, but rather avoiding it if given the possibility to do so.
“it has been suggested that if two individuals have similar motivation to play they are both more likely to perform high levels of play, while individuals with divergent motivation to play could result in the less motivated animal not necessarily participating in play, but rather avoiding it if given the possibility to do so (Douglas et al., 2004;Varlinskaya et al., 1999;Vanderschuren, 2010).”

Positive social stimuli act as natural rewards, and in humans positive social signs such as smiling faces activate reward circuitry.
“Positive social stimuli act as a natural reward; rodents demonstrate conditioned preferences for places previously paired with a social partner (Douglas et al. 2004; Thiele et al. 2008), and in humans, positive social signs such as smiling faces activate reward circuitry (Tsukiura and Cabeza 2008).”

Compared with children, adolescents spend more time with their peers and report more positive affect from this activity.
“Some studies have found that, compared with children, adolescents spend more time with their peers, and report more positive affect from this activity [15,16].”

The opportunity to play with another animal is more rewarding for adolescent rats than for adult rats.
“Conditioned place preference paradigms, in which one compartment is associated with social interaction and the time spent in that compartment is compared with time spent in other compartments, demonstrate that the opportunity to play with another animal is more rewarding for adolescent rats than it is for adults (e.g.[15]).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
