This article presents a model of reading comprehension that accounts for the allocation eye fixations college students scientific passages. The deals with processing at level words, clauses, and text units. Readers make longer pauses points where loads are greater. Greater occur while readers accessing infrequent integrating information from important making inferences ends sentences. forthe gaze duration on each word as function involvement various levels processing. is embedded in...

The cognitive processes in a widely used, nonverbal test of analytic intelligence, the Raven Progressive Matrices Test (Raven, 1962), are analyzed terms which distinguish between higher scoring and lower subjects common to all items on test. analysis is based detailed performance characteristics, such as verbal protocols, eye-fixation patterns, errors. theory expressed pair computer simulation models that perform like median or best college students sample. processing characteristic an...

The brain activation of a group high-functioning autistic participants was measured using functional MRI during sentence comprehension and the results compared with those Verbal IQ-matched control group. groups differed in distribution two key language areas. autism produced reliably more than Wernicke's (left laterosuperior temporal) area less Broca's inferior frontal gyrus) area. Furthermore, connectivity, i.e. degree synchronization or correlation time series activation, between various...

The question of how the human brain represents conceptual knowledge has been debated in many scientific fields. Brain imaging studies have shown that different spatial patterns neural activation are associated with thinking about semantic categories pictures and words (for example, tools, buildings, animals). We present a computational model predicts functional magnetic resonance (fMRI) for which fMRI data not yet available. This is trained combination from trillion-word text corpus observed...

The comprehension of visually presented sentences produces brain activation that increases with the linguistic complexity sentence. volume neural tissue activated (number voxels) during sentence was measured echo-planar functional magnetic resonance imaging. modulation by observed in a network four areas: classical left-hemisphere language areas (the left laterosuperior temporal cortex, or Wernicke's area, and inferior frontal gyrus, Broca's area) their homologous right-hemisphere areas,...

The brain activation of a group high-functioning autistic participants was measured using functional magnetic resonance imaging during the performance Tower London task, in comparison with control matched respect to intelligent quotient, age, and gender. 2 groups generally activated same cortical areas similar degrees. However, there were 3 indications underconnectivity autism. First, degree synchronization (i.e., connectivity or correlation time series activation) between frontal parietal...

This article compares several methods of presenting text, including a new paradigm that produces reading-time data with many the characteristics naturally occurring eye-fixation data. In paradigm, called moving window condition, reader presses button to see each successive work in and previous is removed when appears. The words appear same position they would normal test, word-length information available peripheral vision. results are qualitatively quantitatively compared obtained by...

Brain activity in people with high-functioning autism has been shown to be atypical a number of ways, including reduced synchronization across areas activation measured by functional magnetic resonance imaging. This atypicality observed mostly during the performance cognitive tasks. study compares resting-state network 57 participants and control matched for age intelligence quotient. The results indicate that both groups have is very similar volume organization, but this much more loosely...

Strategic differences in spatial tasks can be explained terms of different cognitive coordinate systems that subjects adopt.The strategy mental rotation occurs many recent experiments uses a system denned by the standard axes our visual world (i.e., horizontal, vertical, and depth axes).Several other possible (and hence strategies) for solving problems occur psychometric tests ability are examined this article.One alternative demands each test item, resulting around arbitrary, taskdefined...

Brain activation and functional connectivity were investigated in high functioning autism using magnetic resonance imaging an n-back working memory task involving photographic face stimuli. The group showed reliably lower compared with controls the inferior left prefrontal area (involved verbal processing maintenance) right posterior temporal (associated theory of mind processing). participants also a somewhat different location fusiform than control participants. These results suggest that...

This study was undertaken to correlate functional recovery from aphasia after acute stroke with the temporal evolution of anatomic, physiological, and changes as measured by MRI.Blood oxygenation level-dependent contrast echo-planar MRI were used map language comprehension in 6 normal adults 2 adult patients during presenting aphasia. Perfusion, diffusion, sodium, conventional anatomic follow physiological structural changes.The activation pattern for showed predominately left-sided...
