Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
The smallest amount by which two sensory stimuli can differ in order for an individual to perceive them as different.
- ‘The difference threshold is the amount of change needed for us to recognize that a change has occurred.’
- ‘In compression coding of picture sequences, a measure of picture difference is generated and compared with a picture difference threshold.’
- ‘We finally see that the difference threshold criteria is fulfilled at 1.725 m.’
- ‘Consequently, a sudden increase in the difference curve is observed at the force peaks, and we have used a difference threshold of 20 pN to identify and localize force events.’
- ‘The most sensitive pigeons had difference thresholds of approximately 0.05 log unit, which corresponds to a difference of about 10% in luminance.’
- ‘The ‘minimum difference threshold’ mentioned above is important from a global performance point of view as well.’
- ‘While, for a given sense modality, there is (subject to the limitations above) one and only one absolute threshold, there are an infinite number of possible difference thresholds, since the size of the difference threshold depends on the magnitude of the stimuli involved.’
- ‘The blue solid line shows the classification performance as a function of the LLR difference threshold.’
- ‘For the Steady-Pedestal Paradigm, the difference thresholds ranged from 0.085 to 0.189 among observers and were significant.’
- ‘In this type of task, intervals are repeatedly presented in a series of trials, and an index of variability, such as a difference threshold, can be estimated.’
- ‘This might be seen as an estimate of the difference threshold.’
- ‘The difference threshold is sometimes called the just noticeable difference, and it depends on the strength of the stimulus.’
