Infant Attention Is Dynamically Modulated With Changing Arousal Levels

Traditional accounts of developing attention and cognition emphasize static individual differences in information encoding; however, work from Aston‐Jones et al. suggests that looking behavior may be dynamically influenced by autonomic arousal. To test this model, a 20‐min testing battery constituting mixed photos and cartoon clips was shown to 53 typical 12‐month‐olds. Look duration was recorded to index attention, and continuous changes in arousal were tracked by measuring heart rate, electrodermal activity, and movement levels. Across three analyses, we found that continuous changes in arousal tracked simultaneous changes in attention measures, as predicted by the Aston‐Jones model. It was also found that changes in arousal tended to precede (occur before) subsequent changes in attention. Implications of these findings are discussed.     

Can we make sense of learning theory?

This article discusses a range of theoretical models of the learning process that have been published in recent years, and examines whether it is possible to relate them systematically to one another. Problems in such an enterprise include those of terminology; globe trotting; the development of separate schools of research that have proceeded largely independently, each with their own central concerns, perspectives, and methodology; and the problem of whether the various different activities popularly described by the word learning do in fact have anything much in common. Despite these difficulties, however, the article argues that the various major models each contain certain key concepts, not necessarily identical in each model, from which it is possible to produce a meta-model - a framework or cognitive map within which the individual models can be located and therefore better understood. The article ends by proposing one such meta-model, and suggesting some ways in which it might be used.     

For Oscar Glory Or Oscar Money?

This paper investigates the effect of Oscar nominations and awards on movies’ financial success by estimating the impact on weekly returns and on movies’ survival time. Our findings suggest that nominations for Oscars generate substantial extra revenues, while winning an award contributes only little to this extra rent.     

The Appeal of Media Populism: The Media Preferences of Citizens with Populist Attitudes

Although a growing body of literature points to the particular media diet of populist voters, we know too little about what specific media preferences characterize citizens with populist attitudes. This article investigates to what extent citizens with antiestablishment and exclusionist populist attitudes are attracted to attitudinal-congruent media content. We collected survey data using a nationally representative sample (N = 809) and found that citizens’ preferences for media content are in sync with their populist attitudes. Beyond having a tabloidized and entertainment-based media diet, populist voters self-select media content that actively articulates the divide between the “innocent” people and “culprit” others. These findings provide new insights into the appeal of different types of media populism among citizens with populist attitudes on different dimensions.     

Communicative Antecedents of Political Persuasion: Political Discussion,Citizen News Creation,and the Moderating Role of Strength of Partisanship

Although much attention has been paid to how media use and interpersonal discussion motivate people to engage in political persuasion, and despite recent efforts to study the role of digital media technologies, less is known about the creation of news and public affairs content online. This study sheds light on how online content creation works alongside other communicative behaviors, such as news use and political discussion, to affect attempted political persuasion. Using two-wave panel survey data, we find that political discussion and citizen news creation mediate the relationships between online and traditional news use, on one hand, and attempted persuasion, on the other. Furthermore, strength of partisanship moderates the relationship between content creation and attempted persuasion. Findings are discussed in light of their implications for the political communication and public sphere processes.     

Sharing the Stage

Despite the proliferation of research on social media and journalism, only a few studies have analyzed how journalists in Latin America embrace the affordances of social platforms for journalism practice. Based on a survey of 877 Latin American reporters, this article examines the platforms journalists use and how they use them. The broad finding is that, despite the great popularity of Facebook in the region, Twitter is the most important platform for daily newsgathering and journalistic work. Journalists turn to Twitter to find sources and stories, showing an important openness to participatory journalism. Yet, they mistrust information provided from political sources. Our findings show that different regions in Latin America work with social media in different ways, and local journalistic cultures have an impact on these adoptions, especially in the case of Brazil. Further research and implications for the field are discussed.
