Recently, several studies have shown that while face-dependent activation within the core face network is observed from at least mid-childhood (Cohen Kadosh and Johnson 2007), face-specific response patterns continue to undergo a prolonged process of fine-tuning and they vary as a function of age and processing proficiency levels (Golarai et al. 2007).
In the context of language processing, proficiency and age of acquisition have reliably been shown to have a strong influence on the functional and structural architecture of the human brain.
A regression analysis using the accuracy rates for the out-of-scanner tasks assessed the differential influence of age or processing proficiency on activation within ROIs.
This suggests that while high processing proficiency might result in stronger neural responses, age was the main predictor of activation within the regions of the face network.
This lack of modulation may contribute to, or reflect, the lower face-processing proficiency levels at this age (Fig. 2 a, and as shown in the out-of-scanner tasks).
A smaller number of studies have suggested that face-processing abilities continue to improve during adolescence (Monk et al. 2003; Yurgelun-Todd and Killgore 2006; Pfeifer et al. 2011), with some studies observing a dip in face-processing proficiency in early adolescence (Carey et al. 1980; Thomas et al. 2007).
Aspects affecting assays include tumor heterogeneity, acquisition and processing of specimens, antibody choices, laboratory assessment protocols, reproducibility of procedures, external assessment of process, proficiency of laboratory workers, sufficiency of scoring positivity and cut-points for positivity [ 1].
Arab students have been shown to encounter greater difficulty with English spelling and word processing than proficiency equivalent ESL learners from other L1 backgrounds.
As business picks up, those companies will need more help processing claims, but proficiency at that takes a lot of experience and training.
Impaired problem solving, visual spatial processing, memory, and cognitive proficiency are consequences of severe alcoholism.
One reason causing such variability is that image quality and attributes vary between different data sets partially due to the differences in imaging modality, imaging parameter, animal model, neuron type, tissue processing protocol, and the proficiency of microscopic operator.
