We examined whether the type of response used to report items recalled from short-term memory affects the age difference in verbal and spatial memory spans. Younger and older adults viewed either a series of letters or a series of locations in a grid, and then they reported their memory for the items either vocally or by using a touch screen. Overall, age differences were larger for spatial mem...

Getting insufficient sleep has serious consequences in terms of mental and physical health. The current study is the first to approach insufficient sleep from a self-regulation perspective by investigating the phenomenon of bedtime procrastination: going to bed later than intended, without having external reasons for doing so. Data from a representative sample of Dutch adults (N = 2431) reveale...

OBJECTIVE We aimed to investigate the prevalence of the metabolic syndrome (MetS) and its individual components in subjects with bipolar disorder (BD) compared to those with major depressive disorder (MDD) and non-psychiatric controls. METHODS We examined 2431 participants (mean age 44.3±13.0, 66.1% female), of whom 241 had BD; 1648 had MDD; and 542 were non-psychiatric controls. The MetS was...

The reaction between reducing sugars and protein free amines, known as the Maillar reaction results in the formation of advanced glycation endproducts (AGEs). AGE modification changes the structure of proteins to amyloid cross-beta structure. These protein structures can activate receptors known as RAGE on glial cells (microglia and astrocytes), and induce the expression of inducible nitric oxi...

We show that deterministic systems with strong nonlinearities seem to be more appropriate to model sandpiles than stochastic systems or deterministic systems in which discontinuities are the only nonlinearity. In particular, we are able to reproduce the breakdown of Self-Organized Criticality found in two well known experiments, that is, a centrally fueled pile [Held et al. Phys. Rev. Lett. 65 ...
