The influence of semantic ambiguity on word identification processes was explored in a series naming and lexical-decision experiments. There no reliable effect 2 experiments, although an advantage lexical decision obtained when orthographically legal nonwords were used. No found iexical illegal used, implying locus for the advantage. These results simulated by using distributed memory model that also produces disadvantage gaze duration has been with reading comprehension task. Ambiguity...
The purpose of this study was to assess cortical activation associated with the cross-education effect an immobilized limb, using functional magnetic resonance imaging.Fourteen right-handed participants were assigned two groups. One group (n = 7) wore a cast and strength trained free arm (CAST-TRAIN). second did not train (CAST). Casts applied nondominant (left) wrist hand. Strength training maximal isometric handgrip contractions (right hand) 5 d·wk(-1). Peak force (handgrip dynamometer),...
Although functional connectivity and associated graph theory measures (e.g., centrality; how centrally important to the network a region is) are widely used in brain research, full extent which these related underlying structural is not yet fully understood. Graph neural deep learning methods have been applied for this purpose, offer an ideal model architecture working with data given their ability capture maintain inherent structure. Here, we predict from sample of 998 participants Human...
A critical question in neuroscience is the extent to which structural connectivity of brain predicts localization function. Recent research has suggested that anatomical can predict functional magnetic resonance imaging (fMRI) responses several cognitive domains, including face, object, scene, and body processing, development word recognition skills (Osher et al., 2016; Saygin 2016). However, this technique not yet been extended skilled reading. Thus, we developed a computational model...
The neural pathways that contribute to force production in humans are currently poorly understood, as the relative roles of corticospinal tract and brainstem pathways, such reticulospinal (RST), vary substantially across species. Using functional magnetic resonance imaging (fMRI), we aimed measure activation pontine reticular nuclei (PRN) during different submaximal handgrip contractions determine potential role PRN modulation. Thirteen neurologically intact participants (age: 28 ± 6 yr)...
The purpose of the present experiment was (a) to replicate standard finding overadditivity between context and degradation when unrelated consists words, (b) assess Lukatela Turvey's assumption that a baseline consisting asterisks is functionally equivalent words
The theory of embodied cognition postulates that the brain represents semantic knowledge as a function interaction between body and environment. goal our research was to provide neuroanatomical examination using action-related pictures words. We used functional magnetic resonance imaging (fMRI) examine whether there were shared and/or unique regions activation an ecologically valid generation task motor in parietal-frontocentral network (PFN), stimulus format (pictures versus words) for two...
The automaticity of reading is often explored through the Stroop effect, whereby color-naming affected by color words. Color associates (e.g., 'sky') also produce a suggesting that automatic occurs to level semantics, even when sub-lexically pseudohomophone 'skigh'). However, several previous experiments have confounded congruency with contingency learning, faster responding for more frequent stimuli. Contingency effects reflect higher frequency-pairing word font in congruent condition than...
The relationship between structural and functional connectivity in the human brain is a core question network neuroscience, topic of paramount importance to our ability meaningfully describe predict outcomes. Graph theory has been used produce measures based on that are related connectivity. These commonly either shortest path routing model or diffusion model, which carry distinct assumptions about how information transferred through network. Unlike routing, assumes most efficient always...
