In understanding the causes of adverse impact, a key parameter is the Black-White difference in cognitive test scores. To advance theory on why Black-White cognitive ability/knowledge test score gaps exist, and on how these gaps develop over time, the current article proposes an inductive explanatory model derived from past empirical findings. According to this theoretical model, Black-White gr...

The acoustic cues of the speech signals which are consisted of consonants and vowels are very important for speech perception in noisy competing situations. Since the perception in noise test is one of the valuable measures in the perception/production abilities, so the objective of this study is to determinate a norm for word recognition in white noise (WN) with a signal-to-noise ratio (SNR) b...

The McCollough orientation-contingent color aftereffect could be equally well elicited by either a full test pattern of black and white stripes or a similar test pattern that was largely occluded by white surfaces, provided the latter stripes were made to appear as through continuing under the white surfaces--by means of stereo depth cues. The color aftereffect appeared concentrated around the ...

We re-examine the theoretical concept of a production function for cognitive achievement, and argue that an indirect production function that depends upon the variables that constrain parents’ choices is both more tractable from an econometric point of view, and more interesting from an economic point of view than is a direct production function that depends upon a detailed list of direct input...
