Catastrophic forgetting occurs when connectionist networks learn new information, and by so doing, forget all previously learned information. This workshop focused primarily on the causes of catastrophic interference, the techniques that have been developed to reduce it, the effect of these techniques on the networks' ability to generalize, and the degree to which prediction of catastrophic for...

The sources of forgetting in working memory (WM) are a matter of intense debate: Is there a time-related decay of memory traces, or is forgetting uniquely due to representation-based interference? In a previous study, we claimed to have provided evidence supporting the temporal decay hypothesis (S. Portrat, P. Barrouillet, & V. Camos, 2008). However, reanalyzing our data, S. Lewandowsky and K. ...

Despite numerous efforts extolling the virtues of formal modeling (Epstein 2008; Schank 2001; Smith & Conrey 2007; Marewksi & Olsson 2009; Farrell & Lewandowsky 2010; Weinhardt & Vancouver 2012; Smaldino et al. 2015), there remains widespread resistance among social and behavioral scientists to adopt formal modeling in their general research approach. In addition to the technical challenge pose...

Pachyonychia congenita (PC) is a rare genodermatosis affecting the nails and other ectodermal tissues. It is mainly characterized by gross thickening of all finger and toe nails. Different additional clinical features are observed; they fit into two major types: the Jadassohn-Lewandowsky and the Jackson-Lawler syndrome. The condition is usually transmitted as an autosomal dominant trait, though...

This issue of Philosophical Transactions examines the relationship between scientific uncertainty about climate change and knowledge. Uncertainty is an inherent feature of the climate system. Considerable effort has therefore been devoted to understanding how to effectively respond to a changing, yet uncertain climate. Politicians and the public often appeal to uncertainty as an argument to del...
