“…The findings of Takahashi and Lore (1983) also support Taylor's (1980) interpretation that juvenile social interactions predict adult aggressiveness. Furthermore, they reveal that adult social play can be measured independently of agonistic behavior.…”

“…A recent theoretical analysis of social play function has postulated that juvenile play may be the primary, initial impetus to engage in spontaneous social interaction and may thus serve to repeatedly bring the individual into physical contact with its social group (Meaney, Stewart, & Beatty, 1985). Other theorists have proposed that social play is an immature form of adult behavior (Takahashi & Lore, 1983;Taylor, 1980) or a form of practice for adult interaction (Panksepp, Siviy, & Normansell, 1984). At present, there is no conclusive evidence or convincing demonstration that can deal with the essential question: What is the biological function of social play?…”

“…Adult play fighting behavior, like that ofjuveniles, is not accompanied by piloerection and is totally lacking in submissive postures. It is also of interest to note that, as animals attain sexual maturity, the quality of social play undergoes little, if any change (Adams & Boice, 1983;Drews, Forand, Gipe, Challel, & Gay, 1982;Takahashi & Lore, 1983;Taylor, 1980). Social play peaks during the developmental interval preceding puberty, that is, 30-40 days of age (Thor & Holloway, 1984a).…”

“…One interpretation of this major change in behavioral ontogeny is related to the coincidental occurrence of sexual maturation and the morphological development of structures supporting male aggressive and sexual behaviors, namely, testicular androgens and androgen-affected systems of the CNS. Indeed, Taylor (1980) affect juvenile play fighting. For example, the increase in circulating androgens associated with the onset of puberty may trigger the development of dopamine autoreceptors in the mesolimbic projection areas, which, in concert with similar endocrinological effects in other feedback systems, may fundamentally alter sensation-seeking behaviors (Spear & Brake, 1983).…”

Pre-and postpubertal play soliciting behavior was observed in intact males, castrate males, sham-operated males, and female controls. Although play soliciting decreased markedly with age in all groups, male treatment groups did not differ reliably on pre-or postpubertal tests. Males, however, engaged in reliably greater play soliciting than females on all measures in both preand postpubertal tests. These results suggest that the major decrease in social play associated with the attainment of sexual maturity is apparent in the play soliciting behavior of both sexes and may be attributed to maturation effects other than that associated with gonadal hormones. The results are discussed in reference to organizational and activational effects of male gonadal hormones on measures of social play behavior.

“…Behavioral changes in cocaine-treated offspring may begin early in life, while the pup is still in the nest, and could change the caretaking behavior of the mothers. There is also evidence for prenatal cocaine-induced suppression of weanling play behavior (23), which has been shown to influence subsequent adult social interactions (22). We suggest that prenatal cocaine exposure results in an overall enhanced reactivity to environmental stimuli that can be observed as alterations in behavior throughout development by tests sensitive to these particular alterations.…”

Children prenatally exposed to cocaine are reported to exhibit inappropriate social behavior, including aggression. We have recently observed a similar phenomenon in rats prenatally exposed to cocaine. Pregnant females were injected twice daily with 15 mg/kg cocaine hydrochloride or saline on gestation days l-20. Offspring were tested for social behavior towards two unfamiliar, untreated rats of the same age and sex. Cocaine-treated males (90 PND) took longer to reciprocate contact and cocaine-treated females (60 PND) spent more time rough grooming unfamiliar females. Male cocaine offspring (180 PND) tested for aggression exhibited an increased frequency and duration and decreased latency to chase an intruder. ACTH was lower in cocaine-treated males (150-180 PND) following plus-maze exposure or exposure to an unfamiliar male. Our data indicate that prenatal cocaine treatment in rats increases fear or aggression responses, dependent on sex and stimulus situation. KeywordsCocaine; Prenatal; Development; Social behavior; Aggression; ACTH; HPA axisThe Alarming rise of cocaine abuse among pregnant women has promoted much concern over the potential behavioral effects on prenatally exposed neonates and infants (4,20). Offspring of mothers that have abused cocaine during pregnancy have exhibited signs of increased irritability and altered state lability as newborns (2,3). Research has also shown that young children prenatally exposed to cocaine are somewhat aggressive, show poor social attachment, and display abnormal play behavior in unstructured environments (7,18). These data are suggestive of a cocaine-induced, abnormal development of socioemotional behavior. However, mothers who have abused cocaine during pregnancy have been shown to bond poorly to their infants (1), making it difficult to determine if the origin of these deficits occur as a direct result of cocaine acting on the developing fetus, being raised in an unstable or abusive environment in which parental drug abuse may be prevalent, or a combination thereof.Recent animal research on the effects of prenatal cocaine exposure has begun to focus on behaviors that appear to be similar to the behaviors exhibited by human offspring prenatally exposed to cocaine. Rodent studies suggest that offspring exposed prenatally to cocaine exhibit signs of behavioral abnormalities including increased "emotionality" and neophobia (5,8), and aggression towards an intruder (9). Though these studies employed cross-fostered Copyright © 1995 offspring, another recent study found that untreated offspring fostered to cocaine-treated mothers also displayed higher levels of shock-elicited aggression (6), suggesting a possible postnatal environmental influence.Based on the previous findings of abnormal behavioral responses of fear and aggression in male rats upon reaching puberty or adulthood, respectively (8,9), the present study was undertaken to determine if these kinds of behaviors changes were task or sex related. We hypothesized that the appearance of the behaviors w...
