Dissociating learning from performance |
Performance is something that one can easily measure. How well does a person remember some facts? How well can an athlete perform a particular task? Learning is something that needs to be inferred from performance - it cannot be observed directly... |

Driver distraction and cell phones |
In this interview Dr. David Strayer from the University of Utah talks about his research on driver distraction and how cell phone use while driving impacts driving behavior. Using different empirical approaches ranging from observational studies to... |

Dual task interference |
The dual-task interference paradigm is one of the hallmarks of Baddeley's approach to working memory. It assumes that if a task selectively interferes with a particular type of processing but not with another type of processing, then those two... |

Early language development |
The acquisition of language in infants has always been a fascinating topic. What do infants hear – prenatally and right after birth? What are infants sensitive to? How and when can they distinguish different words? When do they start to... |

Early left anterior negativity: ELAN |
The early left anterior negativity is a polarization of the electrical field as measured on the scalp through EEG. It appears very early in processing of auditory stimuli (around 150 ms). It is related to the coarse processing of syntactic... |

Edward Awh - Working Memory and Attention |
How many items can a person hold in working memory? This basic question about the basic capacity of human working memory has seen a resurgence of interest over the last ten years. The estimate of 7 plus or minus 2 often reported in textbooks of... |

EEG frequencies |
Professor Niels Birbaumer explains how they use different measures like EEG, MEG, etc. to measure different frequencies of brain waves. He explains how the different techniques allow access to different ranges of brainwaves and how obtaining such... |

EEG/MEG and the time course of language processing |
Electroencephalography (EEG) and magnetoencephalography (MEG) allow the analysis of cortical processing with a very high temporal resolution. The researcher can pinpoint very exactly at which point in time processing is affected by a particular... |

Ethical implications |
Dr. Niels Birbaumer discusses the ethical decisions that face patients, caregivers, and medical personnel when dealing with extreme situations like end stages of cancer or complete paralysis of the body. Decisions such as accepting or withholding... |

Evaluating Heuristics |
How do you evaluate heuristics? Dr. Gigerenzer emphasizes the two different existing approaches that describe the state of the field. In the descriptive approach, researchers try to find out whether people actually use a particular heuristic. In the... |
