Bronchophony may be caused by a solidification of lung tissue around the bronchi – which may indicate lung cancer – or by fluid in the alveoli, which may indicate pneumonia. However, it may also have benign causes, such as wide bronchi. As such, it is usually an indication for further investigation rather than the main basis of a diagnosis.
The only difference between whispered pectoriloquy and bronchophony is the volume at which the patient is asked by the clinician to repeat "ninety-nine" or "baseball." That is, in whispered pectoriloquy, the repeated words are whispered at low volume, and in bronchophony, they are spoken at normal volume.
Egophony (British English, aegophony) is an increased resonance of voice sounds [1] heard when auscultating the lungs, often caused by lung consolidation and fibrosis.It is due to enhanced transmission of high-frequency sound across fluid, such as in abnormal lung tissue, with lower frequencies filtered out.
Symptoms are also grouped in to negative and positive for some mental disorders such as schizophrenia. [36] Positive symptoms are those that are present in the disorder and are not normally experienced by most individuals and reflects an excess or distortion of normal functions; [ 37 ] examples are hallucinations , delusions , and bizarre behavior.
In this case, that parameter is whether air conduction is better than bone conduction. Thus, a "positive" result indicates the healthy state, in contrast to many other medical tests. Therefore, some prefer to avoid using the terms "positive" or "negative", and simply state if the test was normal or abnormal.
However, choices which are made on a person's behalf in their best interest do show a tendency for choice-supportive memory bias. Random selection: People do not show choice-supportive biases when choices are made randomly for them. [12] This is because choice-supportive memory bias tends to arise during the act of making the decision.
Diagram relating pre- and post-test probabilities, with the green curve (upper left half) representing a positive test, and the red curve (lower right half) representing a negative test, for the case of 90% sensitivity and 90% specificity, corresponding to a likelihood ratio positive of 9, and a likelihood ratio negative of 0.111.
The framing effect is a cognitive bias in which people decide between options based on whether the options are presented with positive or negative connotations. [1] Individuals have a tendency to make risk-avoidant choices when options are positively framed, while selecting more loss-avoidant options when presented with a negative frame.
