Attenuation theory, also known as Treisman's attenuation model, is a model of selective attention proposed by Anne Treisman, and can be seen as a revision of Donald Broadbent's filter model. Treisman proposed attenuation theory as a means to explain how unattended stimuli sometimes came to be processed in a more rigorous manner than what ...
Transient hepatic attenuation differences (THAD) are areas of enhancement during the arterial phase of contrast CT of the liver. THAD is thought to be a physiological phenomenon resulting from regional variation in the blood supply by the portal vein and/or the hepatic artery .
The accentuation effect is often found in group interactions, with group members exaggerating the differences between their ingroup and outgroup.For those in the ingroup, the accentuation of characteristics were less for the ingroup than the outgroup, suggesting that this effect may be due to distancing the outgroup from the ingroup.
The focus is an area that extracts information from the visual scene with a high-resolution, the geometric center of which being where visual attention is directed. Surrounding the focus is the fringe of attention, which extracts information in a much more crude fashion (i.e., low-resolution).
The "floor effect" is one type of scale attenuation effect; [3] the other scale attenuation effect is the "ceiling effect". Floor effects are occasionally encountered in psychological testing , when a test designed to estimate some psychological trait has a minimum standard score that may not distinguish some test-takers who differ in their ...
A specific implementation of 1D transient elastography called VCTE has been developed to assess average liver stiffness which correlates to liver fibrosis assessed by liver biopsy. [23] [24] This technique is implemented in a device which can also assess the controlled attenuation parameter (CAP) which is good surrogate marker of liver ...
The "ceiling effect" is one type of scale attenuation effect; [1] the other scale attenuation effect is the "floor effect".The ceiling effect is observed when an independent variable no longer has an effect on a dependent variable, or the level above which variance in an independent variable is no longer measurable.

Liver failure is the inability of the liver to perform its normal synthetic and metabolic functions as part of normal physiology. Two forms are recognised, acute and chronic (cirrhosis). [ 1 ] Recently, a third form of liver failure known as acute-on-chronic liver failure ( ACLF ) is increasingly being recognized.
