limen,threshold- the smallest detectable sensation jnd,just-noticeable difference- (psychophysics) the difference between two stimuli that (under properly controlled experimental conditions) is detected as often as it is undetected Based on WordNet 3.0, Farlex clipart collection. © 2003-2012 Princeton...
3.The difference threshold is not the same for all the senses. very large (20 percent)difference is necessary for some changes in taste to be detected, for instance. In contrast, a difference is noticeable if a musical tone becomes slightly higher or lower in pitch by only about 0.33 perce...
The just-noticeable difference (JND) is the smallest change in sensation that a person is able to detect 50 percent of the time. The difference threshold is a measure of the smallest increase or decrease in a physical stimulus that is required to produce the JND. A person holding a 5-poun...

唯一明显的差异(JND)是一个人在50%的时间内能够检测到的最小的感觉变化。差异阈值是产生JND所需的物理刺激的最小增加或减少的度量。一个持有5磅重物的人会注意到增加了一磅,但一个已经持有100磅的人将无法感觉到额外的一磅。150多年前,研究人员Ernst Weber(1795-1878)观察到,所有感官的JND取决于变化的比例或...
Consumer surplusis defined as the difference between the value that a consumer places on the units purchased and the amount of money that was required to pay for them. the demand curve is the willingness of consumers to pay for each additional unit. ...
The causal effect of a treatment for each individual is defined as the difference in the outcome for an individual had they received that treatment compared to the outcome had they not received it. This is practically impossible to measure directly since typically, only one treatment condition ...
A response to KCl was defined as a ratio increase >10% above baseline. Cells that did not reach this KCl threshold were not included in the analyses. Analysis Fluorescence values for each individual cell were calculated as the mean fluorescence intensity in a user-defined region of interest in...
Δσa and Δσb are the critical threshold of coal at Stages I and Ⅱ, respectively. Δσc is the peak deviatoric stress. As the temperature becomes higher, thermal stress inside the coal induces the swelling in matrix particles and the total matrix volume is expanded (Yin et al., 2013...
