Overall, the results showed that attentional selection based on color occurred early enough to attenuate (but not completely block) semantic processing. One study used MRI to measure the brain activity of subjects while they made semantic decisions. That is, the content of these processes is knowledge about particular entities, events, and relationships. processing of the word that does occur. Semantic and Linguistic Grammars both define a formal way of how a natural language sentence can be understood. Both of these areas have been shown to be involved in many tasks dealing with processing the meaning of words or sentences. Other studies used contrasting tasks to focus subjects' attention on either meaning or word form. Where is the semantic system? In each case, the conditions differ in the extent to which conceptual information about the stimulus can be retrieved. semantic activation in two ways: 1) due to an increase in number of activated word candidates, semantic activation may be too weak to surface as an eye movement to the respective semantic competitor, or 2) semantic activation may be amplified as a function of maintaining one (or few) word candidates for a longer period of time. The lateral prefrontal area seems to be important in holding in mind the information relevant to the task. Their pattern of results shows a frontal–posterior subdivision of MTL activation that depends on the level or depth of semantic processing (coarse versus fine-grained judgments), reminiscent of the orthogenetic (global-to-local) principle in microgenesis. of information and leads to better recall. A common task for studying the brain systems involved in semantic processing is to ask subjects to give the use of a common noun (e.g., hammer). The neural network underlying normal semantic processing has also been studied widely in functional neuroimaging studies of healthy participants; however, these techniques have produced inconsistent findings and are not in complete agreement with neuropsychological studies. The first two possibilities will be peculiar to individual experiments, whereas results that bear on possibility (3) will be more informative about human neurophysiology. The left posterior brain area found to be more active during the processing of the meaning of visual words did not appear until a much later time (500 msec). … When subjects think of the use of a noun, there is an area of positive electrical activity over frontal electrodes starting about 150 msec after the word appears. By continuing you agree to the use of cookies. It is believed that the right hemisphere of the brain commands divergent semantic processing through its coarse grained, large windows of temporal integration. This distinction might be unimportant if the abstraction process is gradual and continuous, such that there is no functional difference between highly abstract multimodal and amodal representations. Generally speaking, the advantage of more efficient semantic processing for pictures than for Chinese characters refers to general processing differences. Positive Mood Can Increase or Decrease Message Scrutiny: The Hedonic Contingency View of Mood and Message Processing Duane T. Wegener Yale University Richard E. Petty Ohio State University Stephen M. Smith North Georgia College Currently dominant explanations of mood effects on persuasive message processing (i.e., cognitive capacity and feelings as information) predict that … A complete theory of human sentence comprehension therefore needs to … An interesting question is whether semantic priming can also increase product liking by enhancing the ease of perceptual processing. Neural Correlates of Semantic Competition during Processing of Ambiguous Words Natalia Y. Bilenko*, Christopher M. Grindrod**, Emily B. Myers, and Sheila E. Blumstein Abstract & The current study investigated the neural correlates that underlie the processing of ambiguous words and the poten-tial effects of semantic competition on that processing. Although the ventrolateral prefrontal cortex includes much of the classical ‘Broca's area’ and is often associated narrowly with speech production, a variety of neuroimaging and neuropsychological evidence indicates that this region plays a key role in top-down activation and selection of semantic information (Jefferies & Lambon Ralph, 2006; Thompson-Schill, D'Esposito, Aguirre, & Farah, 1997; Wagner, Pare-Blagoev, Clark, & Poldrack, 2001). Compositional semantics. Thus, beat gesture and pitch accent may facilitate semantic processing interactively. semantic (ALS) reward and sentence-level semantic (SLS) reward as metrics to improve the quality of text descriptions. A second result suggested that semantic processing was simply not engaged for words outside of the “spatial spotlight”—words on the unattended side elicited little sign of a negative peak in the N400 latency range (i.e., no N400). Participants indicated whether the word target was related to the context word. This effect occurs above chance probability for combined semantic and phonemic relations, and has been viewed as indicative of bidirectional information flow between both lexical processing levels , , . Indeed, recent research by Shoben and Medin [1987] suggests that simple feature-list models may be inadequate to model even some adjective-noun combinations. Accordingly, they found evidence for ACEs in progressive sentences, but not in perfect sentences. To facilitate the learning, we build a new FAshion CAptioning Dataset (FACAD), which In one condition, the auditory stimuli consisted of a single recorded voice, and in the other condition, the auditory stimuli consisted of several different voices. When the subjects showed high confidence and correctly retained the information, the fMRI measured increased activity in the left prefrontal regions. semantic organization per se and increase the likelihood that the deficits lie in one of the many processes involved in access to that information. On the unattended side, there was no difference between related and unrelated trials (no N400 effect), indicating that semantic relationships were not noticed. Results illustrate that the anatomy of this high-level cognitive activity is similar enough among individuals to produce focal average activations that are both statistically significant and reproducible. conditioned response. inflectional processing (MacWhinney & Leinbach, 1991; Joanisse & Seidenberg, 1999), semantic processes have been included to help explain the processing of homophone verbs (e.g. These variables could, in principle, influence the kind of grounded conceptual-semantic representations reviewed (Bergen & Wheeler, 2010). false memory phenomena has increased substantially. trait term (i.e., the name of the trait category) should increase the likelihood that subjects will categorize the stimulus person in terms of the activated category.1 The act of categorization may in turn affect how the stimulus information is processed. The variety of this content is impressive, encompassing object, action, social, self, spatial, and other domains, yet all of it shares a common basis in sensory–motor–affective experience, learning through generalization across individual exemplars, and progressive abstraction from perceptual detail. The small N400 effect for nominally unattended words may indicate that spatial attention is less effective in the auditory than visual modality, or may have reflected slippage of attention to the wrong ear on a small proportion of trials. p(xjc) / p(cjx) p(x) (2) Implied here is the assumption that p(cjx) is proportional Less typical activation is sometimes reported in (c) the left posterior middle temporal and parietal regions associated with semantic processing of auditory and visual stimuli, (d) the triangular part of inferior frontal gyrus involved in accessing phonology from semantics, and (e) the left posterior putamen involved in memory-guided movements with (f) left middle frontal activation when phonological information is minimal or conflicting (Chinese vs. English and Kanji vs. Chinese). One method with which false memories are studied involves using word list paradigms that are based on properties of semantic association and that reliably reveal robust false memory effects. I return to this point about the timing of attentional processes just below, and in the section entitled Preparing to Process Words. Truth-conditional semantics. The results of this experiment support the hypothesis that the bilateral IFG is involved in lexical-semantic processing under conditions of increased competition, showing increased activation for ambiguous words in the presence of a single disambiguating related word compared to unambiguous words. The general semantic network is also virtually identical to the ‘default-mode’ network, defined as regions that show higher levels of activity during passive and ‘resting’ states than during attentional tasks (Binder et al., 1999, 2009; Buckner et al., 2008; Spreng et al., 2009).
