Secondly, the tumour maximal intensity voxel was used because it is largely operator independent, so it controlled for subjective differences in region of interest drawing between centres.
For the purpose of our analyses, we assumed that the score on the applied knowledge test provided a measure of performance that was not influenced by possible subjective biases regarding region of primary medical qualification or ethnicity.
As for the virtual sounds reproduced in the rear region in subjective listing tests, listeners reflected that the perceptual distortions of Cheng's methods were the most serious.
The finding that activity in the vmPFC/OFC shows a strong positive response to learned value fits neatly with a large body of evidence linking this region with subjective valuation [ 11, 30 35], in particular the finding that the vmPFC/OFC encodes the value of a variety of different goods [ 30, 32, 35, 36], which is likely to depend upon prior experience of identical or similar goods.
Parallel to activity in nodes processing object-related impulses is activity in key cerebral regions responsible for subjective assessment and validation: multiple medial regions of the cerebral hemispheres including the pre-SMA, the anterior, mid and perigenual cingulate cortices and medial prefrontal cortex [62].
The scientists also tapped into a recently available, region-by-region assessment of subjective well-being, called the Gallup-Healthways Well-Being Index.
These findings also suggest a possible dissociation between responses in these regions, reflecting subjective impact and experiencing of anxiety-inducing distraction (left visual cortex and vmPFC) vs. actual/objective impact on WM performance (right visual cortex).
All systems for dividing ecological regions are subjective as they require weighting of competing factors, and the use of arbitrary limits and cut-off values, causing a degree of controversy over their adequacy (Omernik 2004), notably regarding their application to Indonesian conservation (Jepson and Whittaker 2002).
They also knew that subjective well-being varies greatly from region to region in the U.S., and is linked to lesser forms of altruism, like volunteer work and charitable giving.
To achieve this objective, and due to a lack of data regarding comfort in built environments in this region, experimental and subjective studies were carried out in 5 big hospitals and 50 small and large shopping centers, distributed in 25 districts of urban areas in Northern Madagascar.
