Memory for Semantically Related and Unrelated Declarative Information: The Benefit of Sleep, the Cost of Wake
(Public Library of Science, 2012)
Numerous studies have examined sleep's influence on a range of hippocampus-dependent declarative memory tasks, from text learning to spatial navigation. In this study, we examined the impact of sleep, wake, and time-of-day ...
Failure of Working Memory Training to Enhance Cognition or Intelligence
(Public Library of Science, 2013)
Fluid intelligence is important for successful functioning in the modern world, but much evidence suggests that fluid intelligence is largely immutable after childhood. Recently, however, researchers have reported gains ...
Perceptual Grouping and Visual Enumeration
(Public Library of Science, 2012)
We used lateralized Event-Related Potential (ERP) measures – the N2pc and CDA/SPCN components – to assess the role of grouping by target similarity during enumeration. Participants saw a variable number (0, 1, 2 or 3) of ...
First Is Best
(Public Library of Science, 2012)
We experience the world serially rather than simultaneously. A century of research on human and nonhuman animals has suggested that the first experience in a series of two or more is cognitively privileged. We report three ...
Human Visual Search Does Not Maximize the Post-Saccadic Probability of Identifying Targets
(Public Library of Science, 2012)
Researchers have conjectured that eye movements during visual search are selected to minimize the number of saccades. The optimal Bayesian eye movement strategy minimizing saccades does not simply direct the eye to whichever ...
