The aim of this study was to explore the association between the consumption of sexually explicit media (SEM) depicting condom and non-condom use and HIV/STI-related sexual risk behavior among men who have sex with men (MSM) in Norway. We also explored whether the association between SEM consumption and STI-related sexual risk behavior is mediated by men’s sexual self-esteem and/or condom use self-efficacy. A cross-sectional online survey study was carried out in Norway in 2012. The final sample comprised 529 MSM in Norway. There was a bivariate association between the use of SEM picturing condom use and less STI-related sexual risk behavior. Further, the association between SEM consumption and sexual risk behavior was mediated by condom use self-efficacy. However, SEM did not influence sexual risk behavior via sexual self-esteem. The results offer important cross-cultural validation of recent comparative data from the US and may be used to promote HIV/STI prevention, in the sense that the actors in SEM may serve as role models in managing condom use in sexual contexts. 相似文献

Children actively and selectively transmit information to others based on the type of information and the context during learning. Four- to 7-year-old children preferentially transmit generalizable information in teaching-like contexts. Although 2-year-old children are able to distinguish between generalizable and non-generalizable information, it is not known whether they likewise transmit generalizable information selectively. We designed a behavioral study to address this question. Two-year-old children were presented with three novel boxes, identical except for their color. In each box, one of two equally salient actions led to a generalizable outcome (e.g., playing a [different] tune in each box), whereas the other led to a non-generalizable outcome (e.g., turning on a light, vibrating the box, or making a noise). In the discovery phase, children had a chance to discover the functions of each box presented one-by-one. Then, in the exploration phase, they were given the opportunity to independently explore all three boxes presented together. Finally, in the transmission phase, an ignorant recipient entered the room and asked the child to show them how these toys work. We measured whether children preferentially transmitted either generalizable or non-generalizable information when they were asked to demonstrate the function of the toys to a naïve adult. We found that children did not display any preference for transmitting generalizable information. These findings are discussed with respect to toddlers’ selectivity in transmitting information but also the development of sensitivity to information generalizability. 相似文献

Active social communication is an effective way for infants to learn about the world. Do pre‐verbal and pre‐pointing infants seek epistemic information from their social partners when motivated to obtain information they cannot discover independently? The present study investigated whether 12‐month‐olds (N = 30) selectively seek information from knowledgeable adults in situations of referential uncertainty. In a live experiment, infants were introduced to two unfamiliar adults, an Informant (reliably labeling objects) and a Non‐Informant (equally socially engaging, but ignorant about object labels). At test, infants were asked to make an impossible choice—locate a novel referent among two novel objects. When facing epistemic uncertainty—but not at other phases of the procedure—infants selectively referred to the Informant rather than the Non‐Informant. These results show that pre‐verbal infants use social referencing to actively and selectively seek information from social partners as part of their interrogative communicative toolkit.

Perceptual-role theories of mental qualities hold that we can discover the nature of a being’s mental qualities by investigating that being’s capacity to make perceptual discriminations. Many advocates of perceptual-role theories hold that the best explanation of these capacities is that mental quality spaces are homomorphic to the spaces of the physical properties that they help to discriminate. This paper disputes this thesis on largely empirical grounds, and offers an alternative. The alternative explains interesting patterns in our perception of color differences and similarities across edges, emphasizing the importance of visual discontinuities. Further, it provides a simple explanation of the intransitivity of indiscriminability. The homomorphism thesis can explain this intransitivity only with the addition of an independently unsupported empirical hypothesis. Also, in contrast to the homomorphism thesis, the alternative view is perfectly consistent with empirical data that suggest (a) that the visual system uses the dynamic allocation of a limited range of responses in order to discriminate a wider range of physical stimuli and (b) that we are much better at detecting changes in relative luminance than changes in absolute luminance. Moreover, it does all this while using a more efficient strategy for encoding sensory information. 相似文献

This study investigated the criterion‐related validity of cognitive ability as well as non‐cognitive ability measures and differences between ethnic majority (N=2365) and minority applicants (N=682) in Dutch police officer selection. Findings confirmed the relatively low predictive validity of cognitive ability generally found for police jobs. Previous research reported no differential prediction. The present study, however, found small but systematic evidence for differences in validity for the ethnic majority and minority group of both cognitive and non‐cognitive measures. For the minority group, training performance appeared to be mainly predicted by the cognitive ability test. For the majority group, cognitive ability showed very little predictive power. Non‐cognitive ability variables appeared to be somewhat more predictive in this group. 相似文献

Infants are curious learners who drive their own cognitive development by imposing structure on their learning environment as they explore. Understanding the mechanisms by which infants structure their own learning is therefore critical to our understanding of development. Here we propose an explicit mechanism for intrinsically motivated information selection that maximizes learning. We first present a neurocomputational model of infant visual category learning, capturing existing empirical data on the role of environmental complexity on learning. Next we “set the model free”, allowing it to select its own stimuli based on a formalization of curiosity and three alternative selection mechanisms. We demonstrate that maximal learning emerges when the model is able to maximize stimulus novelty relative to its internal states, depending on the interaction across learning between the structure of the environment and the plasticity in the learner itself. We discuss the implications of this new curiosity mechanism for both existing computational models of reinforcement learning and for our understanding of this fundamental mechanism in early development. 相似文献

AbstractA defender of any view of moral language must explain how people with different moral views can be be talking to each other, rather than past each other. For expressivists this problem drastically constrains the search for the specific attitude expressed by, say, ‘immoral’. But cognitivists face a similar difficulty; they need to find a specific meaning for ‘immoral’ that underwrites genuine disagreement while accommodating the fact that different speakers have very different criteria for the use of that term. This paper explains how neo-pragmatism deals with this issue while avoiding problems that arise with existing expressivist and cognitivist solutions. 相似文献

Nagel’s constitutive moral luck is one important type of moral luck, but discussions of it have tended to focus on temperament. Luck in how aware a person is of morally relevant aspects of her situation—awareness luck—though similar in some ways, also raises different issues. Luck in temperament impacts how difficult a person finds it to behave well, while awareness luck impacts whether she even recognizes that the situation is making a moral demand on her. For this reason, awareness luck raises some unique challenges for those who would deny the existence of moral luck. 相似文献
