Sex-specific differences in olfactory sensitivity for putative human pheromones in nonhuman primates
Laska M Wieser A Salazar LT 《Journal of comparative psychology (Washington, D.C. : 1983)》2006,120(2):106-112
In humans, the volatile C19-steroids androsta-4,16-dien-3-one (AND) and estra-1,3,5(10),16-tetraen-3-ol (EST) have been shown to modulate autonomic nervous system responses, and to cause hypothalamic activation in a gender-specific manner. Using two conditioning paradigms, the authors here show that pigtail macaques and squirrel monkeys of both sexes were able to detect AND and EST at concentrations in the micromolar and mM range, respectively. Male and female spider monkeys, in contrast, differed markedly in their sensitivity to these two odorous steroids, with males not showing any behavioral responses to the highest concentrations of AND tested and females not responding to the highest concentrations of EST. These data provide the first examples of sex-specific bimodal distributions of olfactory sensitivity in a nonhuman primate species. 相似文献

The purpose of this paper is to demonstrate that Leibniz’s form/matter defense of omnipotence is paradoxical, but not irretrievably
so. Leibniz maintains that God necessarily must concur only in the possibility for evil’s existence in the world (the form
of evil), but there are individual instances of moral evil that are not necessary (the matter of evil) with which God need
not concur. For Leibniz, that there is moral evil in the world is contingent on God’s will (a dimension of divine omnipotence),
with the result that even though it is necessary that God exerts his will, there are particular products of his will that
are contingent and unnecessary—including human moral evil. If there are instances of evil which are contingent on God’s will
and yet unnecessary, then the problematic conclusion for Leibniz’s view must be that human evil depends upon divine concurrence,
not just for its possibility in the world (which is necessary) but for its instance (which is contingent). If the form/matter
defense of omnipotence contains a true paradox, then God concurs in the form as well as the matter of evil. To assuage this
difficulty for Leibniz, I will argue that he could either give up an Augustinian notion of evil, or rely upon a distinction
between *potenta absoluta* and *potenta ordinate*, which was popular among important thinkers in the medieval period. 相似文献

Factor analyses were conducted on scores from the Reynolds Adolescent Adjustment Screening Inventory (RAASI; Reynolds, 2001 ) representing at‐risk Latino youth. The 4‐factor model of the RAASI did not exhibit a good fit. However, evidence of generalizability for Latino youth was noted. 相似文献

Building on the theory of reasoned action (I. Ajzen & M. Fishbein, 1973, 1980; M. Fishbein & I. Ajzen, 1975) and expectancy theory, the authors examined the mediating role of alcohol expectancies in adolescent drinking behaviors by testing whether alcohol expectancy outcomes and valuations (the extent to which these outcomes are perceived as good or bad) mediate the association between peer influences and lifetime alcohol use. Early adolescents (N = 904) from 2 public middle schools in western Michigan completed a battery of questionnaires. Overall, results showed that alcohol expectancies and valuations partially mediated the relations between peer influences (peer use and peer approval) and lifetime alcohol use. The findings suggest that associating with peers who are perceived as using alcohol and approving of drinking may influence adolescents’ alcohol expectancies. The authors briefly discuss future research directions and implications for prevention. 相似文献

An active duty Air Force ground combat unit (n = 189) completed surveys about trauma and combat exposure, mood symptoms, and meaning in life. Two dimensions of deployment-related traumas were assessed: combat (e.g., firing weapons, being fired upon) and aftermath (e.g., seeing dead bodies, injury). Results of regression analyses indicated that Airmen who experienced more intense combat reported less presence of meaning in life, although the significant interaction with gender suggested declines in meaning in life were especially pronounced among males with higher combat intensity. In contrast, more intense aftermath exposure was associated with slightly stronger meaning in life, with no differences by gender. Intensity of combat exposure might differentially affect perceived meaning in life for male versus female combatants. 相似文献

Research shows high risk for depression among immigrant Latinas known to increase during the acculturation process. Several barriers such as stigma and low health literacy result in an under-utilization of needed treatment among these women. In response, this study replicated the effectiveness of a Spanish language fotonovela, a form of Entertainment–Education (E–E), designed to increase depression literacy, decrease stigma, and increase help-seeking knowledge and behavior in Latinos. Specifically, this study evaluated a fotonovela delivered in a multifaceted approach to health education used by promotoras. A pretest–posttest randomized control group experimental design with 142 immigrant Latinas at risk for depression was employed. Results indicate significant posttest improvements in depression knowledge, self-efficacy to identify the need for treatment, and decreased stigma in experimental as compared to control group participants. Findings support the application of E–E health literacy tools such as fotonovelas, delivered in multifaceted approaches to health education used by promotoras, to Latinas at risk for mental health concerns. 相似文献

Twenty neonates of depressed and nondepressed mothers failed to show an initial visual preference for their mother's versus a female stranger's face/voice. Subsequently, infants were habituated to their mother's face and voice. Infants of depressed mothers required 1/3 more trials and almost twice as long to habituate. A posthabituation test with their mother and a different female stranger revealed a preference for the stranger's face for 9 out of the 10 newborns of the nondepressed mothers. Again, the infants of depressed mothers displayed no visual preference. These findings reveal differences in depressed mothers newborns' speed of habituation and face/voice preferences. ©2002 Michigan Association for Infant Mental Health. 相似文献

Predicting having a best friend in young children: individual characteristics and friendship features 总被引:1,自引:0,他引:1
In this study, the authors investigated the characteristics that predict best friend status in young children. One hundred and twenty-four preschool, kindergarten, and first-grade children identified their "best friend" and up to four "other friends" in their class. Teachers completed a questionnaire about each friendship to determine positive and negative features of the relationships. First, the authors used individual characteristics to predict if a child had a best friend. The variables age, gender, and peer acceptance predicted that a child would have a best friend. Second, positive friendship features positively predicted best friendships in analyses of all friendship pairs. Best friendships are meaningful relationships to children even at this young age and offer children more positive experiences than do other friendships. 相似文献
