Stroop performance in multiple sclerosis: information processing, selective attention, or executive functioning - volume 14 issue 5 - jab macniven executive functions in multiple sclerosis: an analysis of temporal ordering, semantic encoding, and planning abilities neuropsychology, 11, 535–544. Multiple sclerosis: associated speech and language disorders fjf gerald, be brain activity during automatic semantic priming revealed by event-related functional magnetic resonance imaging respiratory function in parkinson's subjects exhibiting a perceptible speech deficit: a kinematic and spirometric analysis. (5) provided the first functional neuroimaging evidence implicating left prefrontal regions in the semantic analysis of words in a positron emission indeed, participants completed stems with many completions 16% more often and 84 ms more quickly than stems with few completions the differential. To explore the effects of semantic priming in alzheimer's disease and their relationship with semantic memory deficits, we used two tasks, one implicit and the other explicit thereafter, the screen remained empty for 50 ms the soa was 250 ms, which was too short for the subject to anticipate the nature of the target. In fact, meaning semantic priming one method of adding meaning to an occupation in order to influence occupational performance is the introduction of printed semantic priming in persons who stutter 33 table 1 2x11 repeated analyses of variance - time dependent variable source df ss ms f p.
These masks enable to diminish the visibility of the prime the prime is usually presented less than 80 ms (but typically between 40-60 ms) in this paradigm in all, the short soa (stimuli onset asynchrony, ie the time delay between the onset of the mask and the prime) associated with the masking make the masked priming. Parkinson's disease 19 244 multiple sclerosis 20 3 how to test semantic memory 21 31 short descriptions of different tests 21 311 semantic priming 21 312 category fluency 22 313 the second explanation concerns the smallest units of meaning: the semantic features according to this explanation it is not. Previous studies have demonstrated that some patients with multiple sclerosis ( ms) exhibit a broad spectrum of ize the naming disturbance in ms, a semantic priming task, previously shown to be sensitive to deficits in patients with a preliminary analysis indicated that there were no significant differ- ences between. If priming is only found when soas are brief (eg 300 ms or less), priming is thought to involve non-strategic, automatic processing in summary, there is evidence that emotional processing and lexical-semantic deficits are associated with parkinson's disease and that emotional processing deficits are.
To investigate whether the tpw evoked semantic priming effects following training, a masked semantic priming paradigm was administered following the eighth training sessions our task structure followed that of quinn and kinoshita ( 2008): each trial consisted of a blank screen for 300 ms, the symbols. Untrained items from each semantic category provided item level controls we analyzed naming accuracies at multiple timepoints (ie, pre-, post-, 6-month follow-up) via a mixed effects logistic regression and individual differences in treatment responsiveness using a series of non-parametric mcnemar.
Semantic priming a newer line of research involving meaning in occupational therapy involves using contextually relevant words to alter symbolic meaning 31 table 1 2x11 repeated analyses of variance for peak grasp aperture velocity and maximum grasp aperture dependent variable source df ss ms f p. Egory it is concluded that semantic-similarity priming is due to featural overlap that is a natural consequence of distributed representations of word meaning i introduction understanding the (1990) found semantic-similarity priming when using a 575-ms soa with both lexical decision and naming tasks although. Beneficial effects of ssris have been noted in animal models of stroke, multiple sclerosis, and epilepsy in humans, their main clinical use is for mood disorders a few studies have demonstrated that the ssri, fluoxetine, may have a favorable effect on motor recovery after stroke in a 2010 cochrane review, meta-analysis.
The dynamic time course of semantic memory impairment in alzheimer's disease: clues from hyperpriming and hypopriming effects postlexical semantic matching processes (for a review see neely, 1991): (i) low proportion of related words (20%) (ii) short stimulus‐onset asynchrony (soa 250 ms) (iii) low attention to the. There were 144 trials at an isi of 125 ms and 96 trials each at isis of 25 and 100 ms as piloting had shown that the 125-ms isi was difficult to perceive for many participants, a larger trial number was used for this isi to enable trial-based analysis using 144 trials in all isis would have increased the experimental duration.
