Transfer of information between senders and receivers, of one kind or another, is essential to all life. David Lewis introduced a game theoretic model of the simplest case, where one sender and one receiver have pure common interest. How hard or easy is it for evolution to achieve information transfer in Lewis signaling?. The answers involve surprising subtleties. We discuss some if these in terms of evolutionary dynamics in both finite and infinite populations, with and without mutation. 相似文献

The aim of this study was to assess both violent and nonviolent offending behavior in a single, mixed‐sex population. The rationale for this is that the two types of offending are usually researched separately, despite evidence that they overlap. A comprehensive measure of general violence, intimate partner violence (IPV), and nonviolent offending behavior was administered to 116 men and 181 women, together with measures of personality and personality disorder (PD) traits, to investigate whether predictors of violent and nonviolent offending were similar or different for men and women. Men were found to perpetrate higher levels of general violence and nonviolent offenses than women, but women perpetrated significantly more IPV than men. Cluster B PD traits predicted all three offense types for women and also men's general violence and nonviolent offending. Women's general violence and men's non‐violence also had one unique risk factor each, low agreeableness, and low conscientiousness, respectively. The main difference was for IPV, where men's IPV was predicted by cluster A PD traits, indicating that men's and women's risk factors for IPV may be different, although their risk factors for the other offense types were fairly consistent.

The first explicit argument for the incompatibility of externalism in the philosophy of mind and a priori self-knowledge is
Boghossian’s discrimination argument. In this essay, I oppose the third premise of this argument, trying to show by means
of a thought experiment that possessing the “twater thought” is not an alternative, a fortiori not a relevant alternative,
to having the “water thought.” I then examine a modified version of Boghossian’s argument. The attempt is made to substantiate
the claim that the standard incompatibilist support for its second premise is untenable. Furthermore, a third Boghossian-style
argument is rejected on the ground that either its second premise cannot be warranted in the way suggested by incompatibilists
or its third premise is mistaken because having the “twater thought” instead of the “water thought” is not relevant. Finally,
it is argued that the discrimination argument cannot be saved by invoking closure. The upshot of my discussion is that a compatibilist
can dismiss Boghossian-style arguments for incompatibilism without having to deal with fundamental issues concerning self-knowledge
and the nature of slow switching. 相似文献

The efficiency of cognition is modulated by energetic factors like effort, fatigue or circadian variation, which affect even
the most basic cognitive operations. For instance, speeded detection in simple reaction-time (SRT) tasks usually slows down
over time. The literature suggests that either mindlessness due to routinization or mental fatigue due to attentional resource
depletion might underlie this decrement. We tested these assumptions in three 25-min visual SRT tasks using easy-to-detect
high-intensity and hard-to-detect low-intensity stimuli presented in both blocked and mixed fashion. Mindlessness theory predicts
that less monotonous stimulation (i.e. the mixed presentation) would mitigate the time-related decrement for high- and low-intensity
stimuli alike, whereas resource-depletion theory predicts opposite effects of mixed presentation on high- versus low-intensity
stimuli. Indeed, stimulus intensity and presentation mode cross-interacted significantly, indicating that the performance
decline was steeper for high-intensity stimuli but less steep for low-intensity stimuli during mixed compared to blocked presentation,
respectively. These results strongly suggest that the time-related efficiency decrement during prolonged SRT performance is
related to accumulating mental fatigue. A conjecture is put forward that explains both resource depletion and mindlessness
from the perspective of self-regulation. Our study underscores the need to incorporate energetic factors into models of cognition
to facilitate their translation into real-world applications. 相似文献

The purpose of this study was to investigate consumption patterns of gay‐oriented sexually explicit media (SEM) among men who have sex with men (MSM) in Norway, with a particular emphasis on a possible relationship between gay SEM consumption and HIV risk behavior. Participants included 529 MSM living in Norway recruited online to complete a SEM consumption and sexual risk survey. Of the 507 participants who responded to the all items measuring exposure to SEM, 19% reported unprotected anal intercourse with a casual partner (UAI) in last 90 days, and 14% reported having had sero‐discordant UAI. Among those with UAI experience, 23% reported receptive anal intercourse (R‐UAI) and 37% reported insertive anal intercourse (I‐UAI). SEM consumption was found to be significantly associated with sexual risk behaviors. Participants with increased consumption of bareback SEM reported higher odds of UAI and I‐UAI after adjusting for other factors using multivariable statistics. MSM who started using SEM at a later age reported lower odds of UAI and I‐UAI than MSM who started earlier. Future research should aim at understanding how MSM develop and maintain SEM preferences and the relationship between developmental and maintenance factors and HIV sexual risk behavior. 相似文献

One of the most significant recent advances in the study of semantic processing is the advent of models based on text and other corpora. In this study, we address what impact both the quantitative and qualitative properties of corpora have on mental representations derived from them. More precisely, we evaluate models with different linguistic and mental constraints on their ability to predict semantic relatedness between items from a vast range of domains and categories. We find that a model based on syntactic dependency relations captures significantly less of the variability for all kinds of words, regardless of the semantic relation between them or their abstractness. The largest difference was found for concrete nouns, which are commonly used to assess semantic processing. For both models we find that limited amounts of data suffice in order to obtain reliable predictions. Together, these findings suggest new constraints for the construction of mental models from corpora, both in terms of the corpus size and in terms of the linguistic properties that contribute to mental representations. 相似文献

This review explores social psychological perspectives on the complex relationship between religion and anti‐Black prejudice in the United States. We examine the different ways in which religiosity has been conceptualized by behavioral scientists. We consider the methodological limitations of previous research, as well as how the advent of priming research introduces new empirical questions regarding religiosity and anti‐Black prejudice, such as whether activation of different religious conceptions (e.g., God versus religion) or priming via different types of stimuli (e.g., words versus images) produces different outcomes. Finally, we discuss the lack of diverse samples in the present literature and highlight the need for additional research with Black American respondents. Conclusions consider the real world implications of links between religion and anti‐Blackness for both White individuals (e.g., intergroup relations) and Black individuals (e.g., psychological functioning). 相似文献

Extending our understanding of the interplay between visual and cognitive processes during reading is essential to understand how reading develops and changes across the lifespan. Monitoring readers' eye movements provides a fine-grained online protocol of the reading process as it evolves over time, but until recently eye movements have rarely been collected for young developing and ageing people. Developmental eye-tracking constitutes an emerging and innovative field that addresses various theoretical questions related to changes in the process of reading across the lifespan and the mechanisms that drive intra-individual trajectories and create inter-individual differences among readers. The aim of this editorial is to briefly summarise the current state of the field and to outline which questions are currently being investigated and presented in this Special Issue. 相似文献

We investigated the time course of anaphor resolution in children and whether this is modulated by individual differences in working memory and reading skill. The eye movements of 30 children (10–11 years) were monitored as they read short paragraphs in which (1) the semantic typicality of an antecedent and (2) its distance in relation to an anaphor were orthogonally manipulated. Children showed effects of distance and typicality on the anaphor itself and also on the word to the right of the anaphor, suggesting that anaphoric processing begins immediately but continues after the eyes have left the anaphor. Furthermore, children showed no evidence of resolving anaphors in the most difficult condition (distant atypical antecedent), suggesting that anaphoric processing that is demanding may not occur online in children of this age. Finally, working memory capacity and reading comprehension skill affect the magnitude and time course of typicality and distance effects during anaphoric processing. 相似文献
