We measured Event-Related Potentials (ERPs) and naming times to picture targets preceded by masked words (stimulus onset asynchrony: 80 ms) that shared one of three different types of relationship with the names of the pictures: (1) Identity related, in which the prime was the name of the picture ("socks" - ), (2) Phonemic Onset related, in which the initial segment of the pri...

Subjects were presented with a series of pictures, some of which were general (girl walking down the path) and others specific (girl hiking down the path). These pictures were matched with sentences which were either general or specific ("The girl is walking [hiking] down the path.") Subsequently, a forced-choice picture recognition test was administered in which subjects saw pairs of pictures ...

We investigated whether speakers represent their partners' task in a joint naming paradigm. Two participants took turns in naming pictures; occasionally the (initial) picture was replaced by a different picture (target), signaling that they had to stop naming the initial picture. When the same participant had to name the target picture, he or she completed the name of the initial picture more o...

Primary progressive aphasia (PPA) is a neurodegenerative syndrome that causes a gradual atrophy of the left hemisphere language network, leading to impairments of object naming (anomia) and word comprehension. In 33 human subjects with PPA, object naming and word comprehension were explored with N400 potentials elicited by picture-word or picture-picture matching tasks. Two mechanisms of impair...

In picture-word interference experiments, participants name pictures (e.g., of a cat) while trying to ignore distractor words. Mean response time (RT) is typically longer with semantically related distractor words (e.g., dog) than with unrelated words (e.g., shoe), called semantic interference. Previous research has examined the RT distributional characteristics of distractor effects by perform...

The enhancement of cognitive function in healthy subjects by medication, training or intervention yields increasing political, social and ethical attention. In this paper facilitatory effects of single-pulse TMS and repetitive TMS on a simple picture naming task are presented. A significant shortening of picture naming latencies was observed after single-pulse TMS over Wernicke's area. The accu...

objectives: semantic feature analysis was designed to improve lexical retrieval of aphasic patients via activation of semantic networks of the words. in this approach, the anomic patients are cured with semantic information to assist oral naming. the purpose of this study was to examine the effects of semantic feature analysis treatment on anomia of two nonfluent aphasic patients. methods: a si...

Young and old adults were shown pictured or written verbs and asked to name them as quickly as possible. Simultaneous multiple regression was used to investigate which of a set of potential variables predicted naming speed. Age of acquisition was found to be an important predictor of naming speed in both young and old adults, and for both word and picture naming. Word frequency predicted pictur...
