Perceived stigma, mental health, and campus support among Latina/o and White college students.

College campuses can play a pivotal role in promoting mental health awareness and reducing stigma among college students. This study examines the effect of Latina/o and White students' mental health on their perceived self stigma and public stigma and the moderating role of college and university campuses' support toward perceived stigma. Survey responses of 51,821 Latina/o and White college students were examined.

Longitudinal evidence for the emergence of multiple intelligences in assistance dog puppies.

Cognitive test batteries suggest that adult dogs have different types of cognitive abilities that vary independently. In the current study, we tested puppies repeatedly over a crucial period of development to explore the timing and rate at which these different cognitive skills develop. Service dog puppies (n = 113), raised using two different socialization strategies, were either tested longitudinally (n =91) or at a single time point (n = 22).

Citizen Science as a New Tool in Dog Cognition Research.

Family dogs and dog owners offer a potentially powerful way to conduct citizen science to answer questions about animal behavior that are difficult to answer with more conventional approaches. Here we evaluate the quality of the first data on dog cognition collected by citizen scientists using the Dognition.com website.

Bonobo but not chimpanzee infants use socio-sexual contact with peers.

Bonobos have been observed to use socio-sexual behavior at higher frequency than chimpanzees. Little is known about the developmental influences that shape this behavior in bonobos. We compared the social sexual behavior of wild-born bonobo (n = 8) and chimpanzee (n = 16) infants in an experimental feeding test.

Tolerance allows bonobos to outperform chimpanzees on a cooperative task.

To understand constraints on the evolution of cooperation, we compared the ability of bonobos and chimpanzees to cooperatively solve a food-retrieval problem. We addressed two hypotheses. The "emotional-reactivity hypothesis" predicts that bonobos will cooperate more successfully because tolerance levels are higher in bonobos.

Increased amphetamine-induced locomotion during inactivation of the basolateral amygdala.

At low doses, amphetamine has been shown to produce reliable increases in locomotor activity through its actions on the mesolimbic dopamine (DA) terminals in the nucleus accumbens (NAC). The basolateral amygdala (BLA) has recently been reported to have anatomical projections to the NAC, suggesting that it might serve to alter or modulate the function of the NAC. To test this hypothesis, the current experiment produced lidocaine-reversible lesions of the BLA and assessed changes in NAC function by examining alterations in locomotor activity in response to s.
