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 ...
She proposed an alternative mechanism, attenuation theory. This theory supports an early-selection filter. However, in this case, the filter also attenuates stimuli presented to the unattended channel. If the stimuli pass a threshold, it will leak through the filter and can be attended to.
mass attenuation coefficient, also called mass extinction coefficient, is the attenuation coefficient divided by density; see mass attenuation coefficient for details; absorption cross section and scattering cross section are both quantitatively related to the attenuation coefficient; see absorption cross section and scattering cross section ...
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 ...
The attenuation in the signal of ground motion intensity plays an important role in the assessment of possible strong groundshaking. A seismic wave loses energy as it propagates through the earth (seismic attenuation). This phenomenon is tied into the dispersion of the seismic energy with the distance. There are two types of dissipated energy:
In psychoanalysis, resistance is the individual's efforts to prevent repressed drives, feelings or thoughts from being integrated into conscious awareness. [1]Sigmund Freud, the founder of psychoanalytic theory, developed the concept of resistance as he worked with patients who suddenly developed uncooperative behaviors during the analytic session.
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.

Attenuation distortion is the distortion of an analog signal that occurs during transmission when the transmission medium does not have a flat frequency response across the bandwidth of the medium or the frequency spectrum of the signal. [1] Attenuation distortion occurs when some frequencies are attenuated more than other
