Recent research suggests that information held in working memory can facilitate subsequent attentional processing. Here, we explore the negative corollary of this conception: Under which circumstances does information in working memory disrupt subsequent processing? Seventy participants performed visual discriminations in a dual-task paradigm. They were asked to judge colors or shapes in an online attention task under three different working-memory conditions: Same, Switch, or Unknown. In the Same condition, participants selectively maintained one visual feature in working memory, from the same dimension as in the online attention task. In the Switch condition, participants selectively maintained one visual feature in working memory, but had to focus on another visual dimension in the online attention task. In the Unknown condition, participants could not predict which visual feature would be relevant for the working-memory task. We found that irrelevant features in the online attention task were particularly difficult to ignore in the Switch condition, that is, when the irrelevant features belong to a visual dimension that is simultaneously prioritized in selective working memory. The findings are consistent with accounts in terms of neural overlap between working-memory and attention circuits, and suggest that mechanisms of selection, rather than resource limitations, critically determine the extent of visual interference. 相似文献

Current dynamic-epistemic logics model different types of information change in multi-agent scenarios. We generalize these
logics to a probabilistic setting, obtaining a calculus for multi-agent update with three natural slots: prior probability
on states, occurrence probabilities in the relevant process taking place, and observation probabilities of events. To match
this update mechanism, we present a complete dynamic logic of information change with a probabilistic character. The completeness
proof follows a compositional methodology that applies to a much larger class of dynamic-probabilistic logics as well. Finally,
we discuss how our basic update rule can be parameterized for different update policies, or learning methods. 相似文献

The aim of this paper is to examine W. V.Quine's theory of infants' early acquisition oflanguage, with a narrow focus on Quine's theory ofobservation sentences. Intersubjectivity and sensoryexperiences, the two features that characterise thenotion, receive the most attention. It is argued,following a suggestion from Donald Davidson, thatQuine favours a proximal theory of languageacquisition, i.e., a theory which is focused onprivate experiences as ultimate sources ofstimulation, contrary to a distal theory, where thestimulus source is located in externally observableobjects and events. I use the philosophical criticismof Donald Davidson, Dagfinn Føllesdal and CharlesTaylor to suggest an alternative account of languageacquisition, which emphasises the primacy ofparticipation and joint attention to external stimuli.I argue that such an alternative theory is moreconsistent with recent studies in child developmentand language acquisition. 相似文献

Two studies show that thinking about justice can both enhance and impede forgiveness, depending on whether thoughts about distributive and procedural justice for self and others are activated. In Study 1 (n = 197), participants expressed more forgiveness towards a prior transgressor when primed to think about justice for self or procedural justice for others, and less forgiveness when primed to think about distributive justice for others. Study 2 (n = 231) used an alternate priming method and replicated these effects by inducing an interpersonal transgression and measuring forgiveness intentions, emotions and behavior. Study 2 also showed that priming justice influences forgiveness especially when the perceived severity of an interpersonal offense is high. The current research shows that activating justice cognitions can enhance or impinge on forgiveness in predictable ways. We discuss contributions to emerging justice theory, potential implications, and future directions. 相似文献
