The match-to-sample task has been shown to be an effective tool to understand the impact of sleep deprivation on short-term memory. One research study [9] compared performance on a traditional sequential test battery with that on a synthetic work task requiring subjects to work concurrently on several tasks, testing subjects every three hours during 64 hrs of sleep deprivation.
The single n-back test used was the visual test, leaving out the audio test. [12] In 2011, the same authors showed long-lasting transfer effect in some conditions. [13] Two studies published in 2012 failed to reproduce the effect of dual n-back training on fluid intelligence. These studies found that the effects of training did not transfer to ...
For example, consider a 1 Jy signal from a radio source at a redshift of 1, at a frequency of 1.4 GHz. Ned Wright's cosmology calculator calculates a luminosity distance for a redshift of 1 to be 6701 Mpc = 2×10 26 m giving a radio luminosity of 10 −26 × 4 π (2×10 26 ) 2 / (1 + 1) (1 + 2) = 6×10 26 W Hz −1 .
In psychology and cognitive neuroscience, pattern recognition is a cognitive process that matches information from a stimulus with information retrieved from memory. [1]Pattern recognition occurs when information from the environment is received and entered into short-term memory, causing automatic activation of a specific content of long-term memory.
A comparison between a typical normalized M cone's spectral sensitivity and the CIE 1931 luminosity function for a standard observer in photopic vision. In the CIE 1931 model, Y is the luminance, Z is quasi-equal to blue (of CIE RGB), and X is a mix of the three CIE RGB curves chosen to be nonnegative (see § Definition of the CIE XYZ color space).
Woodsworth (1913) and Margaret and Edward Strong (1916) were the first people to experimentally use and record findings employing the delayed matching to sample task to analyze recognition memory. [7] Following this Benton Underwood was the first person to analyze the concept of recognition errors in relation to words in 1969.

In cognitive psychology, a recall test is a test of memory of mind in which participants are presented with stimuli and then, after a delay, are asked to remember as many of the stimuli as possible. [1]: 123 Memory performance can be indicated by measuring the percentage of stimuli the participant was able to recall. An example of this would be ...
