In their natural environment, animals often make decisions based on abstract relationships among multiple stimulus representations. Humans and other primates can determine not only whether a sensory stimulus differs from a remembered sensory representation, but also how they differ along a particular dimension. However, much remains unknown about how such relative comparisons are made, and which species share this capacity, in part because most studies of sensory-guided decision making have utilized instrumental tasks in which choices are based on very simple stimulus-response associations. Here, we used a two-stimulus-interval discrimination task to test whether rats could determine how two sequentially presented stimuli were related along the dimension of odor quality (i.e., what the stimulus smells like). At a central port, rats sampled and compared two odor mixtures that consisted of spearmint and caraway in different ratios, separated by a 2-4-s interval, and then entered the left or right reward port. Water was delivered at the left if the first mixture consisted of more spearmint than the second did, and at the right otherwise. We found that the difference in mixture ratio predicted choice accuracy. Control experiments suggest that rats were indeed basing their choices on a comparison of odor quality across mixtures and were not using associative strategies. This study is the first demonstration of the use of a sequential "more than versus less than" rule in rats and provides a well-controlled paradigm for studying abstract comparisons in a rodent model system. 相似文献

Occurrence of the home disadvantage in professional ice hockey was examined by analyzing shootout data from 2005 through 2008. Results indicated that teams involved in shootouts playing at their home arenas did not lose significantly more games at home than on the road. Results did not support the hypotheses that emphasize the roles of physical contact and diffusion of responsibility in accounting for past failures to find the home disadvantage in professional ice hockey. 相似文献

The current study was conducted on 60 Israeli female inmates. Our aim was to examine the differences among women convicted for drug, violence, and fraud offenses by socio-demographic variables and self-control and aggression levels. Results revealed that the drug group was characterized by measures attributed to chronic delinquency, and the fraud group was found to fit the pathway to low crime. At the same time, the violence group was not characterized by any of these patterns. The findings were discussed in relation to their theoretical contribution and applicability. 相似文献

Religiosity is a protective factor against illicit drug use, but further investigation is needed to delineate which components of religiosity are protective against use. A racially diverse sample (N = 962) was surveyed about religiosity, exposure to users, and recent use of marijuana, powder cocaine, ecstasy, and nonmedical use of opioids and amphetamine. Results suggest that identifying as Agnostic increased odds of use for each of the five drugs; however, this effect disappeared when controlling for religious importance and attendance. High levels of religious attendance were protective against recent use of marijuana and cocaine, but protective effects diminished when controlling for exposure to users, which was a robust predictor of use of every drug. Religion is a protective mechanism against drug use, but this effect may diminish in light of exposure to users. Alternative preventative methods need to be directed toward individuals who are not religious or are highly exposed to users. 相似文献

Research finds that Americans who espouse theologically conservative beliefs about the Bible generally oppose same‐sex marriage. Studies exploring this link, however, have been limited in that their operationalization of fundamentalist belief has been problematically conceptualized and they have potentially confounded the effect of conservative religious identity. The current study asks: (1) How do distinct beliefs about the nature and authority of the Bible influence same‐sex marriage support? (2) Do these beliefs influence same‐sex marriage support independently of conservative religious identity? (3) To what extent do Bible beliefs and conservative religious identity moderate one another's effects? And (4) to what extent are these factors moderated by religious tradition and frequency of Bible reading? Analyses of 2006 Portraits of American Life Study data reveal that while identifying as religiously conservative is the strongest predictor of opposition to same‐sex marriage, believing in inerrancy and creationism remain strong predictors in full models. I also find moderating effects between belief in creationism, inerrancy, inspiration; religious‐conservative identity; and religious tradition. Findings clarify how theological beliefs and religious identity shape support for same‐sex marriage across religious traditions. 相似文献

Implicit in much of the fatherhood discourse is the assumption that if fathers want to take an active role in their children's lives, they could and would do so. While research has highlighted the factors associated with fathers' involvement, very few, if any, of these studies have been guided by a theory that accounts for both fathers' involvement intentions and their ability to follow through on those intentions. The theory of planned behavior and its emphasis on attitudes, the beliefs of significant others, and whether one has control over engaging in behavior is a conceptual fit to respond to questions related to the complex nature of paternal involvement. Using data from the Fragile Families and Child Well‐being Study, the purpose of this study was to test the utility of the theory of planned behavior in predicting fathers' involvement intentions and reports of involvement. The results revealed that the theory of planned behavior can be useful in examining paternal involvement and should be used in future research to enhance the fatherhood literature. 相似文献
