The most prominent theories of reading consider reading comprehension ability to be a direct consequence of lower-level reading skills. Recently however, research has shown that some children with poor comprehension ability perform normally on tests of lower-level skills (e.g., decoding). One promising line of behavioral research has found semantic processing differences between good and poor c...

Multisensory processes facilitate perception of currently-presented stimuli and can likewise enhance later object recognition. Memories for objects originally encountered in a multisensory context can be more robust than those for objects encountered in an exclusively visual or auditory context [1], upturning the assumption that memory performance is best when encoding and recognition contexts ...

11 Electroencephalography is one of the most popular psychophysiological methods in clinical and 12 preclinical research and provides a recording that reflects the global electrical activity of the 13 brain – the EEG. A limitation of the EEG is that it represents the summation of all the electrical 14 activity at a given moment in time, making it difficult to isolate the activity associated wit...

Electromagnetic activity is generated by neurons in the cerebral cortex and subcortical structures of the brain. Neurons generally differ from other cell types of the body by being specialized for the reception, integration, and conduction of excited states. The shape of the neuron is related to its specialized function. Two types of branching extension of the cell body, the dendrite and the ax...

A method of accurate storage and on-line preprocessing of an EEG signal, preceding and following a trigger signal, elicited by button pressing, is described. The method was used to study the changes occurring in the power of the rhythmic activity within the alpha band in central areas, during voluntary, self-paced movement in 10 normal humans. A short-lasting decrease or phasic event-related de...

Auditory alarm misperception is one of the critical events that lead aircraft pilots to an erroneous flying decision. The rarity of these alarms associated with their possible unreliability may play a role in this misperception. In order to investigate this hypothesis, we manipulated both audiovisual conflict and sound rarity in a simplified landing task. Behavioral data and event related poten...

We present a new technique for studying the activation of semantic and phonological codes in speech planning using event-related brain potentials (ERPs) that extend a well-established behavioral procedure from speech production research. It combines a delayed picture-naming task with a priming procedure. While participants prepared the production of a depicted object's name, they heard an audit...
