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 ...
Others, such as Treisman, believed that Broadbent's model did not account for all such findings. Treisman, a PhD student under Broadbent, proposed feature integration theory, which asserted that to form a perceptual object, we must first look at its features in the preattentive stage and then bind them in the focus attention stage.

Roy employs a six-step nursing process: assessment of behaviour; assessment of stimuli; nursing diagnosis; goal setting; intervention and evaluation. In the first step, the person's behaviour in each of the four modes is observed. This behaviour is compared with norms and is deemed either adaptive or ineffective.
A nursing diagnosis may be part of the nursing process and is a clinical judgment about individual, family, or community experiences/responses to actual or potential health problems/life processes. Nursing diagnoses foster the nurse's independent practice (e.g., patient comfort or relief) compared to dependent interventions driven by physician ...
The mental status examination (MSE) is an important part of the clinical assessment process in neurological and psychiatric practice. It is a structured way of observing and describing a patient's psychological functioning at a given point in time, under the domains of appearance, attitude, behavior, mood and affect, speech, thought process, thought content, perception, cognition, insight, and ...
Feature integration theory is a theory of attention developed in 1980 by Anne Treisman and Garry Gelade that suggests that when perceiving a stimulus, features are "registered early, automatically, and in parallel, while objects are identified separately" and at a later stage in processing.
Nancy Roper, when interviewed by members of the Royal College of Nursing's (RCN) Association of Nursing Students at RCN Congress in 2002 in Harrogate [5] stated that the greatest disappointment she held for the use of the model in the UK was the lack of application of the five factors listed below, citing that these are the factors which make ...
Evidence for the pre-attentive state comes from Treisman's own studies. In a well-known study, Treisman created a display of four objects flanked by two black numbers. The display flashed on a computer screen for 1/5 of a second and followed by a random-dot masking field to eliminate residual perception of the stimuli after the stimuli were ...
