Sleep processes in good sleeper and poor sleeper

Sleeper effects.

Early experience preserves and refines many capabilities that emerge prenatally. Here we describe another role that it plays -- establishing the neural substrate for capabilities that emerge at a much later point in development. The evidence comes from sleeper effects: permanent deficits when early experience was absent in capabilities that normally emerge long after birth. We provide evidence ...

Sleep medicine: no sleeper when it comes to profits.

• Increased consumer focus on sleep by education, regulation and patient selfawareness.7 Sleep medicine is a relatively new field that was officially recognized in the 1960s. Today, an estimated 50 million to 70 million Americans suffer from sleep-related problems.1 The first sleep disorder clinic was opened in 19702 at Stanford University by William Dement, MD. Today more than 2,000 sleep cent...

Microtubule Disassembly: When a Sleeper Is Activated

Tubulin modifications are emerging as interesting mechanisms to regulate microtubule dynamics. A new study shows that phosphorylation of α-tubulin by the atypical kinase PHS1 leads to rapid disassembly of cortical microtubules in plant cells that are under hyperosmotic stresses.

In search of reliable persuasion effects: III. The sleeper effect is dead. Long live the sleeper effect.

The sleeper effect in persuasion is a delayed increase in the impact of a message that is accompanied by a discounting cue. Despite a long history, the sleeper effect has been notoriously difficult to obtain or to replicate, with the exception of a pair of studies by Gruder et al. (1978). We conducted a series of 16 computer-controlled experiments and a replication of the Gruder et al. study to...
