A recent theoretical account posits that, during the acquisition of word recognition in childhood, the pressure to couple visual and language representations in the left hemisphere (LH) results in competition with the LH representation of faces, which consequently become largely, albeit not exclusively, lateralized to the right hemisphere (RH). We explore predictions from this hypothesis using ...

The claim that event-related potentials (ERPs) index familiarity was assessed by acquiring ERPs during a recognition memory task in which participants were instructed to adopt different decision criteria in separate retrieval phases. In one, the instructions were to respond "old" only when confident that this was the correct response, and to respond "new" otherwise (the conservative condition)....

We conjecture that the thought processes used to solve dominant strategy games and mixed strategy games are quite distinct. Two-person games with dominant strategies can be treated as simple decision problems that involve no assessment of one’s partner. By contrast, two-person games with mixed strategies require that one think about one’s partner. We measure differences in electroencephalogram ...

We examined the effects of syntactic (tense) violations occurring on regularly versus irregularly inflected verbs using event-related brain potentials (ERPs). Participants read sentences in which the main verb varied in terms of regularity (regular vs. irregular), frequency (high vs. low), and grammaticality (tense violation vs. no tense violation). For regular verbs, we found a reliable N400 e...

Two experiments investigated the processes underlying the picture superiority effect on recognition memory. Studied pictures were associated with higher accuracy than studied words, regardless of whether test stimuli were words (Experiment 1) or pictures (Experiment 2). Event-related brain potentials (ERPs) recorded during test suggested that the 300-500 msec FN400 old/new effect, hypothesized ...

Objectives: Recent studies with event-related brain potentials (ERPs) investigating music processing found (early) negativities with righthemispheric predominance as a response to inappropriate harmonies within sequences of chords. The stimuli used in those studies were fairly artificial in order to control the experimental factors (e.g. variations in tempo and loudness were eliminated). This r...

Difficulties in phonological processing are currently considered one of the major causes for dyslexia. Nine dyslexic children and eight control children were investigated using functional magnetic resonance imaging (fMRI) during nonoral reading of German words. All subjects silently read words and pronounceable non-words in an event related potentials (ERP) investigation, as well. The fMRI show...

Mulla, Ali, "Electroencephalographic correlates of spatial attention index the degree of online control in goal-directed reaching" (2012). Electronic Thesis and Dissertation Repository. Paper 567. Abstract Goal-directed reaches performed with limb vision (i.e., closed-loop: CL) are more accurate than their limb occluded (i.e., open-loop: OL) counterparts. This finding is frequently attributed t...

Within the dual-process perspective of recognition memory, it has been claimed that familiarity is sufficient to support recognition of single items, but recollection is necessary for associative recognition of item pairs. However, there are some reports suggesting that familiarity might support associative recognition judgments when the items form an easy to access bound representation. In con...
