2014-09-23ZeitschriftenartikelSelf-organized criticality as a fundamental property of neural systems The neural criticality hypothesis states that the brain may be poised in a critical state at a boundary between different types of dynamics. Theoretical and experimental studies show that critical systems often exhibit ...

2012-09-11ZeitschriftenartikelThe effect of task order predictability in audio-visual dual task performance: Just a central capacity limitation? In classic Psychological-Refractory-Period (PRP) dual-task paradigms, decreasing stimulus onset asynchronies (SOA) between the two tasks typically lead to increasing reaction times (RT) to the second task and, when task ...
