A continuous performance task, continuous performance test, or CPT, is any of several kinds of neuropsychological test that measures a person's sustained and selective attention. Sustained attention is the ability to maintain a consistent focus on some continuous activity or stimuli , and is associated with impulsivity .
An enhancement is to use a phase-locked loop to lock the startable oscillator to a more accurate continuous-running crystal oscillator using a technique that preserves the original trigger alignment. The classic Hewlett Packard 5359A Time Synthesizer used a triggered ECL delay-line oscillator synchronized to a crystal oscillator using a ...
For individuals between the ages of 4–5, the T.O.V.A test is 10.9 minutes long, while for older individuals the test lasts 21.6 minutes. The test may be presented as either a Visual or Auditory test, but both measure the same variables. During the first section of the test, the objective is to measure attention during a boring task.
The artificial landscapes presented herein for single-objective optimization problems are taken from Bäck, [1] Haupt et al. [2] and from Rody Oldenhuis software. [3] Given the number of problems (55 in total), just a few are presented here. The test functions used to evaluate the algorithms for MOP were taken from Deb, [4] Binh et al. [5] and ...
On 5 January 1975, the 12-bit field that had been used for dates in the TOPS-10 operating system for DEC PDP-10 computers overflowed, in a bug known as "DATE75". The field value was calculated by taking the number of years since 1964, multiplying by 12, adding the number of months since January, multiplying by 31, and adding the number of days since the start of the month; putting 2 12 − 1 ...
Using the ACS software, examiners can compare performance on these two subtests with performance on the WAIS-IV and WMS-IV, which allows for a more integrated assessment of functioning. In 2011, Crawford et al. made available free computer software that allows the assessor to calculate important supplementary values.
Nesplora Aula is a psychological test in virtual reality that measures attentional processes in children from 6 to 16 years of age. It is a level III C Continuous Performance Test (CPT) that combines auditory and visual stimuli in a virtual environment: a school classroom, alive and organic, with the distractors of that environment.
Plot of the Rosenbrock function of two variables. Here a = 1 , b = 100 {\displaystyle a=1,b=100} , and the minimum value of zero is at ( 1 , 1 ) {\displaystyle (1,1)} . In mathematical optimization , the Rosenbrock function is a non- convex function , introduced by Howard H. Rosenbrock in 1960, which is used as a performance test problem for ...
